I. Introduction

1. We have been asked by National Cable & Telecommunications Association and United States Telecom AssociationFootnote 1 to review and comment on Next Generation Connectivity: A Review of Broadband Internet Transitions and Policy from Around the World, a draft report submitted to the Federal Communications Commission by the Berkman Center for Internet and Society.Footnote 2

2. Our declaration responds specifically to National Broadband Plan Notice #13,Footnote 3 in which the Commission asked for comment on six specific issues:

  1. Does the study accomplish its intended purposes?
  2. Does the study provide a complete and objective survey of the subject matter?
  3. How accurately and comprehensively does the study summarize the broadband experiences of other countries?
  4. How much weight should the Commission give to this study as it develops a National Broadband Plan?
  5. Are additional studies needed along the lines of the Berkman Study?
  6. Please provide any other comments on the Berkman Study that you deem relevant.

3. We conclude that the Berkman Study does not provide a complete or objective survey of the subject matter, nor does it present an accurate or comprehensive summary of the evidence regarding broadband policies in other countries. The study does not serve the Commission's announced purpose of obtaining an "independent expert review of existing literature and studies about broadband deployment and usage throughout the world."Footnote 4 Rather, the study appears to be explicitly biased towards a particular policy agenda, advancing findings and conclusions that conflict with the accumulated evidence found in existing research. The study's attempt to provide new evidence that contradicts this mounting body of evidence fails badly. Accordingly, the Commission should not rely on the Berkman Study's findings in developing its National Broadband Plan.

4. Specifically and most importantly, the Commission should reject what the Berkman Study refers to as its "most surprising and significant" finding, namely that

"open access" policies – unbundling, bitstream access, collocation requirements, wholesaling, and/or functional separation – are almost universally understood as having played a core role in the first generation transition to broadband in most of the high performing countries; that they now play a core role in planning for the next generation transition; and that the positive impact of such policies is strongly supported by the evidence of the first generation broadband transition.Footnote 5

We agree with the Berkman Study that such a finding – if it were supported by the evidence – would indeed be both "surprising" and "significant." Wishing, however, cannot make it so: the incontrovertible fact is that open access policies have not been shown to increase broadband adoption, availability, or infrastructure investment. To the contrary, the bulk of the available evidence points in the opposite direction, and the Berkman Study provides no new evidence that supports a different conclusion.

5. The remainder of this declaration is organized as follows. In Section II, we briefly present our qualifications. In Section III, we discuss the Berkman Study's "review of existing literature and studies about broadband deployment and usage," including its over-reliance on a single, fatally flawed regression analysis to support its conclusions and its failure to mention, let alone comprehensively review, much of the available research on the impact of unbundling policies in the U.S. and around the world. In Section IV, we examine the Berkman Study's "case studies" of broadband policies in selection countries, and find them to be in many cases factually inaccurate, generally misleading, and, overall, unsupportive of the report's conclusions. In Section V, we point out various other errors and omissions in the Berkman Study, which taken together demonstrate further that the report's conclusions cannot be relied upon as the basis for decisions by the Commission. In Section VI, we present a brief summary of our conclusions.

Soumission (suite)

III. The Berkman Study's Conclusions are not Supported by Quantitative Analysis

9. The Berkman Study focuses on two market characteristics associated with broadband diffusion: the intensity of competition and the rate of investment. Unfortunately, it focuses almost exclusively on intra-platform competition and public investment. It discounts the significance of platform competition and of private investment, allowing its authors to ignore the link between policies that promote private investment in competitive platforms, on the one hand, and market performance, on the other.

10. The Berkman Study claims that its attachment to intra-platform competition through mandated network unbundling of incumbent telecommunications networks at regulated prices is grounded in empirical analysis. However, it largely ignores the vast empirical literature that finds no general relationship between network unbundling and broadband penetration, while focusing on one study, by John de Ridder,Footnote 6 which appears to find such a relationship. Based on its re-estimation of de Ridder's original specifications, the Berkman Study finds that mandatory unbundling policies increase broadband penetration by one percent per year. As we explain in Section III (A) below, however, subsequent research demonstrated that de Ridder's results are spurious; and, our further econometric analysis demonstrates that the Berkman Study's efforts to resuscitate de Ridder's results are unsuccessful. Simply put, the quantitative analysis upon which the Berkman Study bases its conclusion that unbundling increases broadband penetration is invalid.

11. Given the Berkman Study's emphasis on unbundling and its mandate to "review existing literature and studies about broadband deployment and usage," we were surprised at its cursory treatment of the extensive existing literature on the effects of unbundling regulation, which on balance fails to support the proposition that unbundling enhances penetration, but does find that unbundling reduces investment incentives, especially for new technologies such as fiber to the premises.Footnote 7

12. In section III (B) below, we conduct the broader review of the existing literature we would have expected to find in the Berkman Study. Our review demonstrates that the bulk of the existing quantitative research finds no basis for concluding that unbundling leads to higher levels of broadband penetration, increased infrastructure investment, or other positive effects on significant public policy objectives.

A. The Berkman Study's "Do-Over" of the de Ridder Study is Fatally Flawed

13. In this section, we review the Berkman Study's econometric analyses, from which it concludes that unbundling policies increase broadband penetration. These analyses are based on the 2007 OECD de Ridder Study. Based on its econometric analysis, the Berkman Study concludes that

consistent with the findings of this recent work, and inconsistent with a recent critique of it, econometric analysis supports the proposition that unbundling contributed to broadband penetration in OECD countries. Indeed, new analyses we perform on the existing data suggest that the effect was larger than previously thought, the confidence level higher, and the finding more robust.Footnote 8

As we demonstrate below, the Berkman Study's econometric analysis does not support any of these conclusions.

14. The de Ridder Study presents least-squares regression results for a model that takes the general form:

Qtot it = a 0 + a 1 GUyrs it + Σ j = 1 n b j X j , it + e it


  • Qtot represents total broadband penetration (as measured by the ratio of broadband connections to population in each country);
  • GUyrs represents the number of years since unbundling policies were enacted in each country;
  • X represents a vector of other explanatory variables (denoted by the index variable j) such as urbanization, average age, or median income;
  • i is an index variable representing the country and t is an index variable representing time;
  • a and b are regression coefficients; and
  • e is a random and identically distributed error term that captures variance unexplained by the model.Footnote 9

15. Simply put, the thesis being tested is that, holding other factors constant, unbundling policies increase broadband penetration, with the effect increasing with the length of time unbundling policies have been in place. Thus, de Ridder estimates least squares regression parameters for various regression specifications to determine whether the coefficient on the unbundling variable (a1 in the equation above) is positive and statistically significant.

16. Specifically, the de Ridder Study estimates seven different regression equations that include the GUyrs policy variable. Four of those seven equations yield a positive coefficient for this variable that is significant at the 5 percent level. On this basis, de Ridder concludes that "unbundling (as measured by GUyrs) is currently more significant than platform competition in explaining broadband penetration."Footnote 10 Obviously, this result supports the Berkman Study's pro-unbundling position.

17. However, the de Ridder Study was effectively critiqued in a 2008 paper by Boyle, Howell and Zhang.Footnote 11 By estimating de Ridder's regressions with robust standard errors, their paper demonstrates that the statistical significance of GUyrs disappears after controlling for heteroskedasticity. In addition, Boyle, Howell, and Zhang showed that GUyrs was likely serving as a proxy for the natural diffusion of broadband into the economy – that is, rather than capturing the time elapsed since the adoption of unbundling, GUyrs was actually capturing, at least in part, the time elapsed since the introduction of DSL.Footnote 12 Indeed, when Boyle, Howell, and Zhang controlled for the number of years broadband service had been available in each country, the GUyrs variable became insignificant in both an economic and statistical sense.Footnote 13

18. The Berkman Study seeks to resuscitate the de Ridder results by making two significant modifications. First, it modifies the GUyrs variable, either by replacing it with a zero-one indicator variable for unbundling, or by replacing the values of GUyrs used by de Ridder with new values.Footnote 14 Second, it applies a more sophisticated econometric technique, utilizing a mixed-effects regression model.Footnote 15 Based on these changes, the Berkman Study concludes that unbundling, whether represented by an indicator variable or a continuous time variable, is generally significant and positive, i.e., that unbundling increases broadband penetration.Footnote 16

19. The Berkman Study's econometric analysis is flawed for three primary reasons. First, it simply fails to address the Boyle-Howell-Zhang critique of the de Ridder Study, which showed that the GUyrs variable is capturing the natural diffusion of broadband over time rather than the effect of unbundling. Second, the mixed effects regressions presented in the Berkman Study fail a Hausman Test for specification, implying that the mixed effects model is inappropriate for this data set and does not produce reliable results. Third, its decision to simply replace the values of the key variable (GUyrs) with values more consistent with its prior beliefs is simply unjustifiable as a matter of econometric technique.

20. In what follows, we present the results of our own regression analysis of the basic de Ridder/Berkman model. Our regressions utilize additional years of data (thus significantly increasing the number of observations, as well as utilizing more recent observations), and apply more appropriate regression specifications and techniques. As we demonstrate, when additional years of data and additional relevant explanatory variables are added – that is, when the model is more fully and correctly specified, and applied to a more complete data set – the effect of unbundling not only disappears but reverses: Rather than increasing broadband penetration, our results demonstrate that unbundling reduces it.

1. The Inclusion of Relevant Data and Explanatory Variables Reverses the Effect of Unbundling on Penetration

21. The primary reason for the de Ridder Study's decision to limit observations to these two years was its use of regressions that include the price of DSL service, for which data is only available for 2002 and 2005. Perhaps because it initially focuses on replicating the de Ridder regressions, the Berkman Study also uses only data from 2002 and 2005.

22. However, as the Berkman Study explains, because the price of DSL service is correlated with the unbundling variable,Footnote 17 it is not appropriate to use price as a separate explanatory ("right-hand-side") variable. Accordingly, in most of its regression specifications, the Berkman Study drops the DSL price variable, which would have allowed it to utilize additional years of data. As we explain further below, our regression analyses rely on data from 2001-2006, for a total of 168 observations.

a. Least-Squares Regression Results

23. To examine the effect of both increases in sample size and the natural diffusion of broadband into the economy, we perform regression analysis on fourth quarter OECD data from 2001 through 2006. Table 1 lists the variables used in the analysis and presents summary statistics. The regression data reflects a 28-country (rather than 30-country) sample, because we were unable to determine the date of DSL availability in Greece and the Slovak Republic.Footnote 18

Table 1: Summary Statistics for Regression Data of 28 OECD Countries (168 Observations)
Variable Description Mean Standard Deviation Minimum Maximum
Qtot Broadband Penetration 9.976 8.497 0.010 31.788
GUyrs Years since unbundling enacted 3.940 2.942 0.000 11.000
unbundled =1 if guyrs > 0

0.839 0.368 0.000 1.000
DSLyears Time since DSL was available 4.238 1.813 0.166 7.667
Pop dens Population density 139.838 133.943 2.527 489.183
Pops Population in millions 40.719 58.814 0.287 299.715
Gdp Gross Domestic Product per capita in US PPP 28720.140 11688.920 6178.182 80471.400
State owned = 1 if network was state owned
= 0 otherwise
0.071 0.258 0.000 1.000

It should be noted that the simple correlation coefficient between variables GUyrs and DSLyears is 0.58. This indicates that, as expected, the two variables share a moderate to strong positive correlation.

24. Table 2 below presents least squares regression results of "reduced form" specificationsFootnote 19 that include DSLyears, and estimate the effect of unbundling using either the GUyrs variable or, in some specifications, Unbundled, which is a one-zero indicator variable.

Variable Coefficient Robust t-Stat Coefficient Robust t-Stat
  Specification 1 Specification 2

Note 1: For both specifications, a White test for heteroskedasticity rejects the null hypothesis of homoskedasticity. We therefore present the regression results with t-Statistics generated from White-Huber standard errors, which account for correlation between the right hand side variables and the error terms in the regression.

Note 2:
*** Denotes significance at 1 percent; (back to table 2)
** denotes significance at 5 percent. (back to table 2)

GUyrs 0.339 1.46
Unbundled -2.232 ** -1.98
DSLyears 2.900 *** 10.21 3.253 *** 16.85
pop dens 0.012 *** 3.19 0.013 *** 3.48
Pops -0.017 *** -4.03 -0.013 *** -3.56
Gdp 0.000 *** 5.06 0.000 *** 7.71
state owned -7.400 *** -4.26 -9.602 *** -6.17
Constant -10.042 *** -7.43 -10.544 *** -9.17
  N = 168 N = 168
  R-squared = 0.72 R-squared = 0.72
  F (zero slopes) = 83.94 F (zero slopes) = 76.41

25. To begin, the regression results in Table 2 first show that the explanatory variables in the model are, in general, statistically significant at a 1 percent significance level. Specifically, the coefficient on DSLyears is positive and significant in both regression specifications, and positive coefficients on population density and GDP indicate that broadband penetration tends to be higher in wealthier economies and in countries with higher population densities, but lower in larger countries (those with large populations) and in countries where the telecommunications network is state-owned. All of these effects are of the anticipated sign.

26. Regarding unbundling, the Berkman Study found that the effect of GUyrs was positive and statistically significant at 1 percent. But when DSLyears is inserted into the equation, as in Specification 1, the effect disappears, indicating that the number of years unbundling policies have been in place has no independent effect on broadband penetration, and confirming the result in Boyle-Howell-Zhang that GUyrs is simply a proxy for the number of years since DSL was first introduced.Footnote 20

27. As explained above, the correct question with respect to unbundling is whether it shifts the technology diffusion curve, so that, other things equal, broadband penetration increases more rapidly in countries that adopt unbundling. To test this proposition, we introduce the indicator variable Unbundled in a regression that also controls for the time that DSL has been available in each country. The second regression specification in Table 2 provides the results of this test: as the table shows, the coefficient on Unbundled is negative and statistically significant.Footnote 21 This result indicates that unbundling has slowed the pace of broadband adoption in the sample countries, a result which directly contradicts the Berkman Study, but, as we note below, is consistent with prior empirical research.

b. Fixed Effects, Random Effects, and Generalized Least Squares

28. We next extend the above regressions to the estimation of fixed effects, random effects, and generalized least-squares models. A fixed effects regression essentially involves the inclusion of country-specific indicator variables in the model, and is a common practice in panel datasets. Random effects regressions take advantage of variation across countries without the inclusion of indicator variables for each country in an attempt to estimate the right hand side variables in a more efficient manner than fixed effects. Applying generalized least squares to panel data allows one to control for both heteroskedasticity (a cross-sectional data problem) and autocorrelation (a time-series problem).

Pops -0.5699 *** -2.89 -0.0137 -0.85 -0.0296 ** -2.34
Gdp 0.0009 *** 5.24 0.0004 *** 4.7 0.0007 *** 6.31
Constant 14.199 0.6 -11.351 *** -4.64 -17.321 *** -5.06
  N = 168 N = 168 N = 168
  R-squared (within) = 0.88 R-squared (within) = 0.86 Chi-Squared = 1367.86
  R-squared (between) = 0 R-squared (between) = 0.33    
  R-Squared (overall) = 0.01 R-Squared (overall) = 0.61    

29. The results reported in Table 3 show that the Unbundled variable has a negative coefficient when any of these panel data techniques is used. In the case of fixed and random effects, the Unbundled variable is negative and statistically significant at 1 percent. In the GLS model controlling for both autocorrelationFootnote 22 and heteroskedasticity, Unbundled is again negative, and significant at 5.4 percent. Therefore, panel data analysis supports the least-squares results presented in Table 2 above – namely, that unbundling reduces broadband penetration.

30. It is also worth noting that in the fixed effects regression, the effect for the United States is both positive and statistically significant. That is, the fixed effect regression indicates that the United States has broadband penetration above what the model predicts based on the other control variables in the model, such as wealth and population density. Moreover, the United States fixed effect is statistically significant at 1 percent both in regressions that apply traditional standard errors and in regressions that use robust heteroskedastic-consistent standard errors. This finding indicates that a characteristic not specifically controlled for in the model is causing higher broadband penetration in the U.S. than the model itself predicts. Plausible candidates for such a characteristic include tastes (i.e. consumer preferences), the presence of robust infrastructure competition, or policy variables (other than unbundling) not captured in the model.

2. The Mixed Effects Regressions in the Berkman Study Fail a Hausman Specification Test

31. As noted above, in addition to least squares models, the Berkman Study estimated a mixed effects model,Footnote 23 which contains both fixed and random effects. In a mixed effects model, fixed effects are estimated directly and the random effects are calculated indirectly via an estimated variance-covariance matrix.Footnote 24 As a result, a mixed effects estimator attempts to take advantage of information contained in variation between countries, whereas the fixed effects estimator includes controls for each specific country. Both techniques allow one to estimate a regression coefficient on a variable such as GDP or GUyrs, but the two estimation techniques analyze the data differently. A benefit of the random effects model is that it has greater degrees of freedom, because the estimation of many indicator variables is unnecessary.Footnote 25 Random effects estimation, however, relies on an assumption that the random effect itself is uncorrelated with the right hand side variables in the regression, which may be unlikely.

32. The key factor in selecting between fixed effects and random effects models is whether the assumptions underlying the random effects approach holds. If the effect is uncorrelated with other right hand side variables, then random effects is consistent and efficient relative to fixed effects. If this assumption fails, however, random effects models are inconsistent, and the fixed effects approach is preferred.

33. The appropriate test for determining which approach is preferred is the Hausman Specification Test,Footnote 26 which we applied to the data used in the de Ridder and Berkman analyses. The test is constructed as follows. First, both models are estimated in accordance with the original de Ridder specification, with price on the right-hand side. Next, the coefficients and variance-covariance matrices are statistically compared between the two models. If significant differences exist, then a mixed (or random) effects approach is superior. Otherwise, the fixed effects regression is preferred. We found that the Berkman Study's mixed-effects model failed the Hausman Test: That is, contrary to the Berkman Study's contentions, the mixed effects model does not offer statistical efficiency above that of the fixed effects model. Moreover, when we estimated the fixed effects model using the de Ridder data, the positive effects of unbundling highlighted in the Berkman Study disappear.

34. To perform the Hausman Test, we first estimated a fixed effects model on the following variables:Footnote 27

  • log of DSL price (lnpdsl)
  • Urbanization (uurb)
  • Facilities competition (Cfac)
  • Years of unbundling (GUyrs)
  • Indicator variable for 2005 (Dummy)

We found that the coefficient on GUyrs is statistically insignificant.

35. Next, we estimated both a random effects model and a mixed effects model using identical regressors to the fixed effects regression outlined above. The Hausman Test generated a Chi-Squared statistic of 3.33 when comparing random to fixed effects, and a statistic of 4.04 when comparing the mixed and fixed effects estimates. Neither of these statistics was sufficiently large to reject the null hypothesis that fixed effects is the more efficient estimator.Footnote 28 Consequently, the regression results presented in the Berkman Study are questionable not only because of the limited data sample and the exclusion of a relevant variable, but also because they result from use of an inappropriate regression technique.

3. The Berkman Study Makes Inappropriate Modifications to the Data

36. In several of its regression specifications, the Berkman Study changes the underlying data used by de Ridder. Specifically, as shown in Table 4.8 of the Berkman Study, the authors altered 17 of the 30 values of GUyrs from the values used in the original de Ridder analysis. Using the altered data, the Berkman Study finds that GUyrs "seems to have larger effects" and "is much more significant."Footnote 29 Given the nature of the data alterations, these results are hardly surprising.

37. As the Berkman Study notes, its data alterations result "in many more countries defined to have GUyrs = 0 than before."Footnote 30 More specifically, the countries for which GUyrs were set to zero were Belgium, United States, United Kingdom, Luxembourg, Germany, Ireland, Poland, and Greece. The average value of Qtot in 2005 for these eight countries was 11.22, significantly below the average of 14.14 for all 30 countries. (The lower average for the eight "zeroed-out" countries is driven primarily by Ireland, Poland, and Greece, which have particularly low broadband penetration.) Thus, the positive effect of GUyrs in the regression specifications utilizing the altered data is the result of the exclusion of three countries that had very low broadband penetration but had adopted unbundling. In addition, the United States is assigned zero years of unbundling in 2005 despite the fact that it began to require unbundling in 1996 and, for a time, even required line sharing. And Germany is also assigned a zero, despite the fact that ECTA reported that it had 2.5 million unbundled lines devoted to broadband out of a national total of 10.7 million broadband lines!Footnote 31 In other words, many of the regression results reported by the Berkman Study are the result of simply replacing the values for selected observations with data points that are more favorable to its conclusions. Obviously, the Commission should not base its policies on analyses of what amounts to manufactured data.

B. The Evidence from Other Quantitative Studies Does Not Support Unbundling

38. In addition to the de Ridder Study, there is a significant body of quantitative research into the effects of mandatory unbundling on broadband penetration. Despite its mandate to conduct a "review of existing literature and studies about broadband deployment and usage," the 231-page Berkman Study devotes only half a paragraph to reviewing this literature, briefly mentioning only five studies, two of which it concedes do not find unbundling to have a significant effect on penetration. Nevertheless, based on its highly selective literature review, the Berkman Study concludes that "unbundling had a positive and significant effect on levels of penetration."Footnote 32 In this section, we conduct a more complete review of the existing literature and show, contrary to the Berkman Study's conclusion, that the vast majority of studies find either no relationship or a negative relationship between unbundling and broadband penetration. We also note that most studies also find evidence that platform competition – i.e., the U.S. model, which is rejected by the Berkman Study – does have a positive and significant effect. In short, the quantitative evidence is directly contrary to the Berkman Study's policy recommendations.

1. Summary of Prior Empirical Studies

39. Table 4 summarizes the pre-existing empirical literature on broadband penetration, availability, and mandated unbundling. As the table shows, the bulk of the studies surveyed do not support the proposition that mandated unbundling, with its focus on intraplatform competition, increases broadband penetration or deployment. Most studies find the relationship to be either a negative or insignificant. The few studies reporting positive effects fail to provide persuasive evidence, owing to various biases and data deficiencies. On the other hand, the majority of the studies examining the role of inter-platform competition (all but one) find that competition across platforms leads to increased broadband penetration. Thus, the existing literature suggests that mandatory unbundling is either ineffective or counterproductive in increasing broadband penetration.

Table 4: Summary of Empirical Studies

* Distaso, Lupi & Mantenti (2005) find that inter-platform competition is a substantial driver of broadband penetration, and that competition within the market for DSL services does not play a significant role. Somewhat paradoxically, the researchers also find that a decrease in the local loop unbundling price has a positive and significant effect on penetration. However, as noted above, their econometric analysis assumes that mandated access prices are exogenous, implying that this effect may reflect reverse causality.

40. In addition to the studies summarized in Table 4, there is a substantial empirical literature on the relationship between unbundling and investment. As we discuss below, the evidence from these studies strongly supports the hypothesis that unbundling regulation reduces infrastructure investment

2. Studies Finding Negative and/or Insignificant Effects of Unbundling on Penetration

41. As shown in Table 4, we identified nine studies that find either a negative or an insignificant effect of unbundling on broadband penetration.

42. First, using a cross-section of 46 U.S. states from the year 2000, Aron and Burnstein (2003) estimate the effect of intermodal competition on broadband penetration, relative to the effect of simple broadband availability, while controlling for various demand and cost drivers.Footnote 33 The authors measure head-to-head intermodal competition as the percentage of the population in a given state residing in cities where both cable modem and DSL are deployed; broadband availability is measured by the percentage of the population of a given state residing in cities where cable modem or DSL have been deployed. The demand controls include the percentage of households with internet access and an education metric; the cost controls include a metric for teledensity (measuring the number of switched access lines per mile), the average length of a local switched access line, and the regulated price of an unbundled network element.Footnote 34

43. The regression results reveal that, although broadband penetration is positively correlated with broadband availability, this effect disappears after controlling for intermodal competition. Thus, for a given level of demand and cost drivers, an increase in broadband availability in areas without intermodal competition does not stimulate additional adoption of broadband. Furthermore, the relationship between unbundled access prices and penetration is not statistically significant.Footnote 35

44. Analyzing a cross-section of 30 OECD countries from the year 2001, Bauer, Kim, and Wildman (2003) examine the effect of various policy variables on broadband penetration, including unbundling, cable-telco cross ownership, and government funding for broadband.Footnote 36 The researchers allocated the countries in their sample into one of three clusters, depending on the extent to which each of these policies was in place. The authors find that two factors, the population density and the "preparedness" of a given country (as captured by an index measuring attitudes towards advanced information technologies and the availability of complementary technologies, such as computers) are consistently significant in explaining broadband penetration. The analysis fails to detect any statistically significant relationship between membership in a given policy cluster and broadband penetration.Footnote 37

45. Denni and Gruber (2005)Footnote 38 analyze biannual state-level panel data from 1999 to 2004 in an effort to determine the extent to which intra- versus inter-platform competition affects broadband penetration, using a logistic model of technology diffusion. The dependent variable in their model is the ratio of broadband subscribers to the population of a given state. Inter-platform competition is measured with a modified version of the traditional Herfindahl index, using technologies' market shares instead of firms' market shares.Footnote 39 Intra-platform competition is measured somewhat differently, using a special case of the Herfindahl index that applies when all firms have symmetric shares.Footnote 40 Due to the potential endogeneity of these competition indices, the authors use lagged values of the endogenous variables as instruments.

46. The authors find that inter-platform completion plays a far more important role than intra-platform competition in determining the rate of diffusion of broadband infrastructure: Inter-platform competition is shown to have a substantial positive effect on diffusion in the long run, whereas intra-platform competition has only a small initial effect that rapidly dissipates. Furthermore, the authors find that mandatory unbundling actually inhibits broadband penetration. Specifically, the results indicate that the share of central offices upgraded for equal access has a negative and statistically significant effect on the rate of broadband diffusion.Footnote 41

47. Distaso, Lupi, and Manenti (2005) develop and estimate a model of oligopolistic competition between differentiated products to analyze the relative importance of intra-platform competition and inter-platform competition in driving broadband adoption.Footnote 42 A key implication of their theoretical model is that inter-platform competition (between alternative platform providers such as cable companies and fiber-optic providers) should be more effective than intra-platform competition (competition among incumbents and DSL providers using unbundled loops) in increasing broadband penetration.Footnote 43

48. When estimating their model, the authors employ a panel data set of 14 European countries running from the fourth quarter of 2000 through the second quarter of 2004. The dependent variable in each of their econometric specifications is broadband penetration, as measured by the percentage of all access lines (copper, cable, fiber, and satellite) that have been upgraded to transmit high-speed data.Footnote 44 The authors measure the degree of intra-platform competition as the level of concentration in the DSL market, using a standard Herfindahl index. The degree of inter-platform competition is modeled using a modified Herfindahl index, computed using technologies' market shares instead of firms' market shares, as in Denni and Gruber (2005). To control for potential endogeneity of the competition metrics, the two Herfindahl indices are instrumented using their lagged values.

49. Consistent with their theoretical predictions, the authors find that, although interplatform competition is a substantial driver of broadband adoption, competition within the market for DSL services – the type of intra-platform competition that mandatory unbundling of broadband is designed to stimulate – does not play a significant role.Footnote 45

50. Cava-Ferreruela and Alabau-Munoz (2006),Footnote 46 employing data from a panel of 30 OECD countries from 2000 to 2002, explore the determinants of wireline broadband coverage, (defined as the percentage of local loops that are DSL-enabled), as well as cable broadband coverage (defined as the percentage of homes passed by cable television networks).Footnote 47 The analysis indicates that gross national income per capita is the single most important determinant of both DSL coverage and cable coverage. The authors also find evidence that the share of DSL-enabled local loops is dramatically higher in countries where inter-platform competition is more robust, whether measured by the presence of cable infrastructures or by the number of competitors operating competing broadband platforms. In contrast, neither the existence of unbundling regulations nor the number of unbundled loops is found to be significantly correlated with DSL coverage.Footnote 48

51. Using a panel of 30 OECD countries from 1999-2003, Wallsten (2006) investigates the determinants of broadband subscribers per capita. Wallsten's regression analysis includes dummy variables for (1) various types of unbundling regulation (full unbundling, bitstream unbundling, and subloop unbundling); (2) collocation regulations; and, (3) access price regulation. The regressions also control for GDP per capita, and the number of fixed telephone lines per capita.Footnote 49

52. In his fully specified model, which includes time and country fixed effects, Wallsten finds no consistent evidence that full unbundling has a positive effect on penetration. The effect of full unbundling is positive and significant in some specifications, negative and significant in others, and statistically insignificant in his full specifications that include all covariates. With respect to bitstream unbundling, the estimated coefficients are positive, but statistically insignificant in the full specification. Furthermore, with respect to sub-loop unbundling, the effect on penetration is consistently negative and statistically significant. Wallsten does find evidence that on-site collocation requirements are positively and significantly correlated with penetration. However, he also finds a negative and statistically significant relationship between regulation of collocation charges and broadband penetration.Footnote 50

53. Waverman, Meschi, Reillier, and Dasgupta (2007) employ a panel of 12 European countries from 2002-2006 to estimate the effect of unbundling on broadband penetration.Footnote 51 The researchers' control variables include GDP, a lagged Herfindahl index (computed using technology platform shares) and the share of internet-ready cable plant.Footnote 52 Mandatory unbundling is captured with a variable measuring the price of a fully unbundled local loop as well as the number of years since unbundling was implemented. The coefficient on the unbundled price is also allowed to vary depending on whether bitstream access is available. The authors report that the number of years since adoption of unbundling has no statistically significant effect on penetration, and that the coefficients on the unbundled price variables are negative and statistically significant. This implies that that lower unbundling rates induced substitution away from alternative platforms and toward copper platforms, and that the net effect over the sample period was to steeply reduce the number of broadband consumers.Footnote 53

54. As noted above, Boyle, Howell, and Zhang (2008) analyze a panel of 30 OECD countries from 2002 – 2005 to estimate the determinants of broadband penetration under two sets of specifications.Footnote 54 In one set of regressions, unbundling is measured with a simple indicator variable equal to one if the country has implemented local loop unbundling in the year in question, and zero else. In a second set of specifications, unbundling is measured as the number of years since local loop unbundling was first implemented. The authors control for the retail price of DSL, the urban percentage of the population, the age of the population, and the number of non-DSL connections as a percentage of total broadband connections (to control for the presence of competing platforms).

55. The second set of regressions also includes a variable equal to the number of years for which broadband technology has been available in each country, to control for diffusion of broadband over time. (In the absence of this control variable, the unbundling variable employed in the second set of regressions might simply reflect spurious, diffusiondriven correlations). In all specifications, the authors find that the relationship between unbundling and penetration is statistically insignificant.Footnote 55 Finally, the authors do not find a statistically significant relationship between platform competition and penetration, although, unlike most researchers, they do not attempt to correct for endogeneity in the competition metric.

56. Finally, using a biannual panel of 27 European countries from 2002 to 2007, Wallsten and Haulsaden (2009) investigate the effects of unbundling on the penetration of nextgeneration broadband technology.Footnote 56 The authors estimate a regression in which the number of fiber broadband connections per capita is specified as a function of GDP per capita and the number of unbundled lines per capita (defined as the number of per-capita DLS connections offered over either unbundled loops or through bitstream unbundling). The authors also include country and time fixed effects. Estimating separate equations for incumbents and entrants, the authors find, in both cases, that the relationship between unbundling and fiber per capita is negative and statistically significant.Footnote 57

3. Studies Finding Positive Effects of Unbundling on Penetration

57. Garcia-Murillo (2005) analyzes a cross-section of countries from 2001 to investigate the factors determining broadband availability and penetration, using two types of specifications.Footnote 58 The first set of results is of limited interest in the current context, because the dependent variable is a simple, binary indicator of whether broadband has been deployed at all in a given country. Such an analysis is incapable of assessing the degree to which unbundling does (or does not) increase penetration or investment in countries where broadband has already been deployed.

58. The dependent variable employed by Garcia-Murillo in the second set of regressions, the percentage of internet users subscribing to broadband, is more relevant. Explanatory variables in these regressions include GDP per capita, the retail price of broadband, the number of broadband providers, the percentage of internet users, and an indicator for unbundling, which is found to be positive and statistically significant in one specification. However, the sample size is quite small (less than 20), and many of the econometric results are quite anomalous, which calls the overall reliability of the model into question. For example, GDP per capita is found to have no statistically significant effect on penetration, while the estimated relationship between broadband penetration and the retail price of broadband is positive and statistically significant.Footnote 59

59. Grosso (2006) analyzes a panel of 30 OECD countries from 2001-2004, and estimates an econometric model in which broadband penetration is a function of several variables, including a dummy variable for local loop unbundling.Footnote 60 Additional independent variables in the model include GDP per capita and lagged broadband penetration, as well as a variant of the Herfindahl index computed using technology (platform) shares to measure crossplatform competition. The econometric results indicate a negative and statistically significant relationship between the Herfindahl index and broadband penetration, indicating that crossplatform competition increases broadband penetration. In addition, the relationship between unbundling and penetration is positive and statistically significant. However, due in part to data limitations, several key explanatory variables are omitted from the analysis, including demand and cost drivers such as the price of broadband and population density.Footnote 61

60. Importantly, both Garcia-Murillo (2005) and Grosso (2006), along with nearly all empirical researchers, assume that unbundling policies are exogenous when estimating the effect of unbundling on broadband penetration. This ignores the fact that regulatory outcomes such as mandated access prices and the adoption of unbundling policy regimes are subject to political and administrative processes, which implies that they are endogenous.Footnote 62 Endogeneity bias is driven by the fact that regulators may respond to incumbents' infrastructure investments by providing easier access to entrants (by mandating unbundling and/or lowering access prices). Thus, unbundling may appear to drive increased investment and broadband penetration, when in fact the causation runs in the opposite direction. Only a handful of studies have attempted to assess the empirical magnitude of this source of bias. Those that have find substantial evidence of endogenous regulation.Footnote 63

61. Moreover, as we discussed above in the context of the de Ridder Study, few empirical studies control for the fact that the passage of time should have a substantial effect on penetration, due to technology diffusion. So-called general purpose technologies, such as broadband, tend to follow a well-known "S-shaped" curve as they mature.Footnote 64 While initially only early adopters find it worthwhile to purchase the technology, eventually the technology achieves mass-market acceptance and adoption accelerates. Finally, the rate of adoption begins to level off as saturation approaches, and the few remaining non-adopters tend to be those who place a relatively low value on the technology. As noted above, Boyle et. al. (2008) have shown that failure to control for diffusion over time can lead to spurious correlations between unbundling and penetration. Furthermore, this effect will be exacerbated by endogenous regulatory outcomes, to the extent that regulatory commitment problems become more acute with movements along the diffusion curve, as broadband adoption – and the infrastructure investments that make it possible – begin to accelerate.

4. Studies Relating Unbundling to Network Investment

62. There is also a large body of empirical work focusing on the relationship between mandatory unbundling and network investment, which has demonstrated that mandatory unbundling discourages investment by both incumbents and entrantsFootnote 65 and thus calls into question the "stepping stone" hypothesis,Footnote 66 which posits that mandatory unbundling can create a set of "rungs" on a "ladder of investment" allowing entrants to invest gradually in their own facilities. Indeed, the primary author of the ladder of investment thesis, Dr. Martin Cave, has acknowledged that it "remains no more than a hypothesis, as scientific testing of an imprecise proposition of this kind remains problematic."Footnote 67 The most recent authoritative review of the literature on unbundling and investment examines more than 20 empirical studies of access regulation and investment incentives, and concludes that while additional research could be useful, "most of the evidence shows that local loop unbundling…discourages both ILECs and CLECs from investing in networks."Footnote 68 The summary table from that study is reproduced as Exhibit E to this Declaration.

63. The Berkman Study does not express disagreement with the above results. Rather, it simply ignores the effect of policy on private network investment. Instead it focuses approvingly on public investment in broadband network infrastructure. It should be noted that many countries whose regulatory policies have failed to induce investment by incumbents or entrants are now turning to public investment to remedy their policy errors.Footnote 69 We doubt that U.S. authorities would welcome such an outcome.

  2. 7 The United States has been a leader in network investment, in large part as a result of its rejection of overly broad unbundling policies, but the Berkman Study chooses to ignore this encouraging result, perhaps because it conflicts with its policy recommendations.

  10. 15 The de Ridder Study performs least-squares regressions on a 30 country sample from 2005, and a pooled 54 observation sample by adding 24 data points from 2002; it also differenced the two data sets and performed regressions on the resulting 24-country sample. The regressions on the differenced data, however, did not include the GUyrs variable, as differencing it would result in a constant of 3 across all observations, which would result in the dropping of the variable from the regression. That is, one cannot estimate a regression parameter for a "variable" that does not vary. (back to footnote reference 15)

  13. 18 Our regression data are presented in Exhibit D, so that others can replicate our results and also perform original analysis using the data. We also note that more recent OECD reports have updated certain data series. To be clear, we have used broadband penetration data from Table 1G of the OECD's December 2008 Broadband Report. These data are available from the OECD Broadband Portal, at,3343,en_2649_34225_38690102_1_1_1_1,00.html. Prior series are available in the December reports for various years, which are available at,3381,en_2649_34225_1_119656_1_1_1,00.html. (back to footnote reference 18)
  14. 19 The exclusion of price in the equations is appropriate because price is an endogenous variable that is likely correlated with the disturbance term in the Qtot regression.. Under a linear two equation model with Qtot and Price as dependent variables, the Price equation would serve as the cost equation, with the right hand side variables that affect the build out and operation of the broadband network. Population density, for example, would be a natural cost shifter that would serve this purpose. Substituting for price in the Qtot equation then yields the reduced form equation, which excludes Price, but still controls for its affect. An alternative approach would be to instrument for Price using two-stage least squares. Additional data on price over time would be required to perform this correction. (back to footnote reference 19)
  15. 20 Our confidence in this conclusion is further strengthened by the fact that, if we replicate the Berkman Study's misspecification, we get the same result: When DSLyears is removed from our regression, GUyrs becomes positive and statistically significant at 1 percent. (back to footnote reference 20)
  16. 22 An AR1 process was estimated, yielding a constant autocorrelation coefficient of 0.99 for all countries. There were 28 separate estimated covariances for the heteroskedasticity correction. Relaxing the heteroskedasticity correction yields similar results. The population variable, however, is insignificant, and the p-value for the Unbundled variable is 0.08.

In particular, substituting that formulation of GUyrs still results in a failure of both random and mixed effects relative to fixed effects. Moreover, the GUyrs variable in the fixed effects model is not statistically significant. (back to footnote reference 28)

IV. The Berkman Study's Conclusions are not Supported by Qualitative Analysis

64. To advance its case for an expanded network unbundling regime in the United States, the Berkman Study attempts to buttress its quantitative analysis with extensive discussions of unbundling policies in various OECD countries. While it does not suggest that every country that has pursued unbundling has achieved success through such a policy, its general conclusion is that unbundling has generally had favorable effects. As we explain below, like the quantitative evidence, the qualitative evidence does not support the Berkman Study's conclusions.

A. The Alleged Successes

65. The Berkman Study concludes that network unbundling has generated competition, lower prices, and greater broadband penetration in several Nordic countries, the Netherlands, France, the United Kingdom, and Japan. A careful examination of available data for each of these countries suggests that the Berkman Study's conclusions are either incorrect or, at best, vastly overstated.

1. The Nordic Countries and Netherlands

66. A cursory look at the OECD broadband penetration rankings reveals that a large share of the best performers are cold, northern countries – Denmark, Norway, Sweden, Finland, Netherlands, and Iceland occupy the top six positions. Countries with more moderate climates, such as Italy, Spain, New Zealand, and Australia are far down the OECD list. Equally important, despite substantial differences in policy across these Nordic countries, all are converging to a very similar level of broadband penetration as Figure 1 shows.Footnote 70 This might suggest that cultural, weather, or other demand factors explain a large share of the variance in penetration, but the Berkman Study chooses to focus on network access policies. Its discussion of even the "best" performers is not persuasive.

Figure 1 : Broadband Penetration, 2001-08
Broadband Penetration, 2001-08

Source: OECD [Description of figure 1]

67. In discussing the Nordic countries, the Berkman Study is somewhat equivocal about the effects of network unbundling. With respect to Denmark, for example, it simply concludes that

Competition developed both within each technological platform, and across platforms; to some extent benefiting from unbundling when it was available, and to some extent benefiting from relatively low levels of investment necessary to upgrade an existing infrastructure like cable….Footnote 71

The report does not point out to the reader that cable modems exceed the number of unbundled and shared lines in Denmark,Footnote 72 or that cable modem competition in Denmark was highly developed before the recent growth of unbundled lines to deliver DSL.Footnote 73 Thus, intra-platform competition appears to have followed inter-platform competition in Denmark, and the available empirical evidence suggests that such inter-platform competition is far more important than intra-platform competition.

68. In Sweden, platform competition has also been responsible for more broadband subscriptions than has network unbundling. As of the first quarter of 2009, cable connections and non-incumbent telco fiber to the home, provided largely over government fiber networks, accounted for 1.2 million connections while DSL over unbundled and shared loops for only 600,000 connections, and the number of lines delivered over unbundled/shared lines is actually declining.Footnote 74 Much of Sweden's "success' derives from its government-provided fiber, not from network unbundling. Nevertheless, the Berkman Study relies on the views of the Swedish regulator:

Convinced by the perceived success of unbundling in fostering competition, investment, and innovation in its broadband markets, concerned about managing the transition to next generation networks, and possibly smarting from the long fought battle over bitstream access, the Swedish regulator PTS concluded that it would best manage the transition to next generation connectivity by imposing functional separation on its incumbent.Footnote 75

69. This is a curious conclusion, given that the incumbent has not been among the leaders in the EU in network investment and only has 12 percent of the country's fiber connections. The transition to next generation networks in Sweden has been over networks built largely by municipal governments, not by the incumbent operator.

70. The Berkman Study's dismissal of the effect of unbundling in Finland is similarly curious. It asserts that "Finland was the first Nordic country to introduce unbundling, in 1996. Unbundling seems to have had little or no effect in the Finnish market, however."Footnote 76 But according to latest ECTA data, broadband delivered over unbundled and shared loops accounted for 25 percent of all broadband lines while they accounted for only 18 percent in Sweden, a country that the Berkman Study argues is a "perceived success of unbundling." Notably, Finland – an early adopter of network unbundling – has not deployed any fiber to the home according to the ECTA data.

71. Finally, in the case of Netherlands, the Berkman Study suggests that network unbundling plays a critical role in allowing facilities-based entrants, the cable companies, to address customers in areas where they lack facilities. But unbundled and shared lines accounted for only about 680,000 lines in March 2009 while broadband over cable accounted for 2.2 million lines according to the latest ECTA data. And despite the Berkman Study's glowing description of the incumbent's (KPN's) decision to offer unbundled fiber to its competitors, the latest ECTA data show no such unbundling. Perhaps more important, the ECTA data show that entrants have 140,000 subscribers over their own fiber, but KPN has none, and the latest data from IDATE show that KPN has yet to even deploy FTTH.Footnote 77

2. France

72. The Berkman Study makes much of differences between France's and Germany's unbundling policies. It paints the French policy since 2002 in very rosy terms, pointing out that an EC infringement action forced the French regulator to mandate lower rates for unbundled and shared loops. Subsequently, in 2003 new entrants expanded rapidly. By contrast, the German regulator is described as unwilling to enforce an unbundling regime that works.Footnote 78 These differences in policy lead the Berkman Study to opine that: "Despite having roughly similar GDP per capita (Germany slightly higher) and population concentration (France slightly higher), the two countries present quite different trajectories."Footnote 79 What trajectories is it referencing? A quick look at Figure 2 shows that the trajectory of broadband penetration since 2003 is very similar in the two countries. Why worry about differences in unbundling policy, given this obvious fact? Figure 2 shows that Germany actually experienced slightly greater broadband growth after 2003, a result that is largely due to the greater growth of inter-platform competition from cable television. Germany now has about 2 million cable broadband subscribers – more than twice the number in France.Footnote 80

73. Moreover, both France and Germany remain far below the Nordic countries and Netherlands in terms of broadband penetration. Neither has yet to deploy much fiber to the subscriber. France had only 40,000 fiber loops in the first quarter of this year, out of a total of more than 18 million broadband connections; Germany had none. By contrast, Verizon alone had 3.3 million FTTH broadband connections at the end of the third quarter of 2009. Thus, while unbundling has created competition among suppliers of DSL in France, it has not led entrants or incumbents to invest much in fiber to the subscriber. Despite the Berkman Study's assertion that France Telecom has responded with "higher investment," its capital spending as a share of revenues remains mired in the very lowest echelons of capital spending among EU-15 incumbents.Footnote 81

3. The United Kingdom

74. Two of the authors of this declaration were co-authors of an earlier study of network separation policies that is being published this year in the Federal Communications Law Journal. In that article, we reviewed in great depth the results of Ofcom's new (2005) unbundling and functional separation policy. We concluded that under this policy the rate of growth of the UK's broadband subscribers had declined relative to the growth in the overall EU-15.

75. Specifically, we showed that:

A comparison of UK broadband growth with growth in the EU-15 yields a similarly bleak conclusion about the effects of functional separation. According to ECTA data, between September 2002 and September 2005, when the new Ofcom policy went into effect, UK broadband lines increased at an annual rate of 76 percent while EU-15 broadband lines rose at a rate of 54 percent. Thus, prior to the change in policy, the rate of increase in UK broadband lines was 41 percent greater than the rate of increase in the EU-15. In the three years following the implementation of the new Ofcom policy, UK broadband line growth fell to 21 percent, and EU-15 broadband line growth fell to 23 percent.Footnote 82 …Thus, the new policy has been associated with a severe decline in UK growth relative to the growth in the EU-15. Indeed, the UK broadband growth rate is now less than the average rate for the entire EU-15, and broadband penetration in the UK has fallen relative to EU-15 penetration in the three years that the policy has been in place.Footnote 83

76. The recent ECTA data do not alter this conclusion; UK broadband subscriptions have grown more slowly than EU-15 subscriptions over the 3.25 years since the new unbundling regime went into effect in the third quarter of 2005. Nor do the ECTA data show any fiber deployment in the United Kingdom through the first quarter of this year. The policy has simply not worked to accelerate the growth of broadband or encourage deployment of a Next Generation Network.

4. Japan

77. The authors of the Berkman Study would have us believe that Japan's policy of network unbundling has been an unqualified success, although it admits that facilities-based competition is driving fiber deployment. It claims that the Japanese regulator's decision to require fiber unbundling has not deterred fiber investment: "…the overall level of investment in the fiber market questions the argument that open access deters investment."Footnote 84 However, we can find no evidence that NTT has actually delivered a significant number – or, for that matter, any number – of unbundled fiber connections. Fiber "unbundling" has not deterred NTT's investment in FTTH for a simple reason: fiber unbundling has not been implemented in a meaningful manner.

78. Contrary to the impression created by the Berkman Study, Softbank (Yahoo!BB) states in its most recent annual report that it is losing broadband DSL customers steadily, and it reports no customers over NTT's fiber plant. Indeed, the Softbank 2009 annual report downplays any discussion of the decline in its wireline broadband business, simply stating that it is reducing capital expenditures in its fixed-wire operations: "…the segment's profitability and cash flow are showing marked increases. This reflects a lower depreciation from the end of major capital expenditures, combined with a structural transformation toward businesses."Footnote 85 It is not investing in fiber to the home or any other form of residential connections, but rather shifting its attention to the business market.

79. In short, the unbundling era in Japan appears to be fading rapidly. DSL subscriptions have been declining for three years. Fiber connections, supplied by NTT and a host of other platform-based competitors now substantially exceed DSL connections. The principal competitors of NTT in delivering broadband over fiber optics are the country's power companies, not the companies who have used NTT's copper loops to deliver DSL service.Footnote 86 At this point, these power companies are deploying fiber without any apparent concern that they will have to unbundle their fiber networks. Platform competition, not network unbundling, is driving fiber deployment in Japan.

B. The Doubtful Cases or Outright Regulatory "Failures"

80. The Berkman Study reviews the regulatory developments in several OECD countries, citing their failure to embrace network unbundling, or the failure to implement it assertively, as a regulatory mistake. These countries include South Korea, Germany (already discussed), Italy, New Zealand, and Canada.

1. South Korea

81. No matter how the Berkman Study tries to characterize it, the South Korean broadband policy is a triumph for platform-based competition. The Study argues that:

The South Korean experience is more ambiguous on access, pointing more toward heavy government investment. Both (Japan and South Korea) suggest that a strong, professional regulator, exercising effective power over incumbent providers, can foster significant market development and competition.Footnote 87

82. But this "strong" regulation essentially amounted to subsidizing capital investments by the cable and electric utility companies, but discouraging these companies from offering retail broadband Internet services over their own platforms. As a result, new entrants sprang up offering broadband services over their own platforms and over the cable companies' and electric companies' networks.

83. As the Berkman Study correctly observes, this platform competition led to rapid growth in Korean broadband before any unbundling requirements were imposed on the incumbent telco, KT, in 2002. By that time, Korea had by far the highest broadband penetration in the OECD –21.8 percent versus an average of 4.8 percent in the OECD. Since 2002, Korea's penetration has grown very slowly, expanding by less than 50 percent to 32 percent in December 2008 while the average OECD country has nearly quintupled its penetration to 22.4 percent. Four Nordic countries and the Netherlands have surpassed Korea since its new unbundling requirement took effect in 2002.Footnote 88 Thus, unbundling had nothing to do with South Korea's spectacular early broadband growth.

2. Italy

84. The Italian regulator required network unbundling in 2001 and then required functional separation of Telecom Italia in 2006-08. As of March 2009, entrants using unbundled or shared lines accounted for 27 percent of all lines. The principal problem in Italy had been the absence of platform competition since it had virtually no cable television. Platform competition did emerge in the form of Fastweb'sFootnote 89 fiber deployment in large cities, but this deployment has now been halted. Fastweb has chosen to grow only through leasing Telecom Italia's loops now that functional separation of TI assures them of rapid access to TI's loops as TI's own retail division.Footnote 90 Thus, contrary to the Berkman Study's assertion that Fastweb will continue to deploy fiber and share it with TI, Fastweb has chosen to abandon further fiber investment because of recently improved access to TI's unbundled loops. Fastweb's recent decision is evidence of the adverse effect of mandated network sharing on investment in new technologies. But Italy's relatively low broadband penetration probably has little to do with its regulatory policy. Rather, it is likely a reflection of low personal computer penetration in the country.Footnote 91

3. New Zealand

85. New Zealand had decided not to mandate network unbundling in 2003, but the Communications Ministry changed course in 2006. The government imposed network unbundling and structural separation of Telecom New Zealand in December 2006, undoubtedly because broadband penetration was relatively low, and there was very little platform competition. Since that time, New Zealand's broadband penetration has grown more rapidly than the OECD average, but New Zealand's penetration is still below the OECD average. Moreover, there is no sign of fiber to the premises deployment by Telecom New Zealand or its competitors.

4. Canada

86. Canada's broadband policy has been similar to that in the United States. Canada has very strong platform competition from cable, a fact that propelled it to second place in OECD broadband penetration in 2001. As in the United States, cable broadband connections have exceeded DSL connections from the very beginning. Thus, inter-platform competition was extremely strong in Canada from the outset. Canada has had network unbundling regulations in place since 1997, but few entrants have succeeded in using unbundled loops for delivering broadband or other telecommunications services to residential customers perhaps because of the strength of inter-platform competition in most regional Canadian markets. Most of the local entrants using unbundled loops were unable to compete in this environment and either failed or were acquired. The Berkman Study is incorrect, however, when it asserts that "[t]here are no smaller entrants of note."Footnote 92 MTS-Allstream has been using Bell Canada's and Telus's local loops for years, but with little apparent effect on broadband penetration because its principal focus has been the business market, not the residential market. Thus, while unbundled loops have been available in Canada for more than a decade, they have not been used successfully by entrants to compete in the mass market for broadband services.

C. Conclusions

87. The Berkman Study has failed to unearth any systematic anecdotal information that mandated network unbundling has increased broadband penetration in OECD countries. This is hardly surprising given the preponderance of empirical studies which conclude that unbundling has limited or no effect. Its narrative does often suggest, however, that platform competition is important in driving competition in countries such as South Korea, the Nordic countries, Canada, and the Netherlands. This too is consistent with the published empirical evidence.

88. The Berkman Study's focus on unbundling of copper loops to promote intraplatform competition is misplaced. The issue for U.S. regulators today is not how to increase competition in DSL services, but rather how to encourage the development of new, faster networks. Even if unbundling copper loops had been a mild success in promoting DSL, this result would not suggest that a similar policy would be successful in promoting the development of new fiber-based networks. Indeed, we have shown that the empirical literature on network investment and access regulation shows that mandated access regulation reduces the incentive to invest in new network technologies.

89. The Berkman Study is critical of the United States and Canadian policies for not being sufficiently aggressive in promoting network sharing and is correspondingly approving of a general European regulatory bias towards encouraging such sharing. Unfortunately for the Europeans, their more aggressive regulatory policy has resulted in far less deployment of fiber in the European Union than in North America as demonstrated by Figures 3 and 4.

V. The Berkman Study's Analysis is Flawed in Other Significant Respects

90. In addition to the errors noted above, the Berkman Study relies on erroneous analyses or makes misleading assertions on a number of fronts. In the sections below, we focus on four of these: (A) its over-reliance on bivariate analysis and "scatter plots" to support its conclusions; (B) its mischaracterization of the evolution of U.S. broadband policy; (C) its mischaracterization of the policy consensus abroad, especially in the European Union.

A. The Berkman Study Relies Almost Exclusively on Bivariate Analysis

91. Bivariate analysis – the comparison of two sets of data to determine the extent to which one variable is correlated with another – can be a useful means of describing the relationships between variables, and as a starting point for more rigorous multivariate (i.e., regression) analysis. It cannot, however, take the place of multivariate analysis, and can almost never support valid findings of causality. Yet, the Berkman Study relies heavily on such analysis to support its conclusions, presenting scatter plot after scatter plot, depicting everything from the relationship between broadband penetration and entrepreneurship (Figure 2.3) to the relationship between average download speeds and median download speeds (Figure 3.191-i). Identifying and critiquing each and every instance in which the Berkman Study relies inappropriately (explicitly or implicitly) on such comparisons to support its conclusions would require far more space than we can justify here.

92. We do, however, point out one particularly egregious (and significant) example of how bivariate analysis can be used to present misleading information: Figure 4.2 of the Berkman Study (reproduced below) presents a scatter plot which shows the results of one of the two quantitative analyses contained in the study, a survey of broadband price and speed offerings by 59 companies in OECD countries. The Berkman Study relies heavily on this analysis for its conclusions, stating that the figure

shows that prices and speeds at the highest tiers of service follow a clear pattern. The highest prices for the lowest speeds are overwhelmingly offered by firms in the United States and Canada, all of which inhabit markets structured around "inter-modal" competition – that is, competition between one incumbent owning a telephone system, and one incumbent owning a cable system.Footnote 93

Moreover, subsequent to the study's release, author Yochai Benkler (in the course of responding to various criticisms of the study) posted a blog entry in which he stated that Figure 4.2 shows results that "are consistent with the open access hypothesis, and inconsistent with the inter-modal competition hypothesis," and that it supports "the basic storyline," that "Where a regulator rolled up its sleeves and really implemented open access, new and innovative entrants used the opportunity to invest in new service models and new electronics, introduced bundled voice over IP, or IPTV, or nomadic access."Footnote 94

Figure 5 : Berkman Study Scatter Plot of Broadband Prices and Speeds by Different Providers
Berkman Study Scatter Plot of Broadband Prices and Speeds by Different Providers

Source: Berkman Center analysis of OECD Broadband Statistics and Global Comms 3.0
Note: Includes highest speed offerings from US players with minimum 2 million subscribers [Description of figure 5]

93. While the Berkman Study's Figure 4.2 may appear visually to support the Berkman Study's "basic story line," the figure hardly constitutes "analysis" and provides virtually no basis for any conclusions about the relationship between unbundling and investment. For example:

  1. Most obviously, the figure fails to account for other variables that likely affect the cost (and hence price) of broadband services, such as loop lengths, urbanicity, dwelling type (multi-dwelling units vs. single-family homes), and topology;
  2. By the same token, the figure fails to account for policy variables other than unbundling (e.g., government subsidies) which likely affect both costs and prices;
  3. The data presented shows only each carrier's "highest speed offering," which may or may not be utilized by a significant number of consumers;Footnote 95
  4. The figure compares data points for firms (such as Verizon and Qwest) that serve large, low-density areas with firms (such as Fastweb) that serve only dense urban areas.

94. Thus, even leaving aside issues of measurement (e.g, whether advertised speeds faithfully reflect delivered speeds), the "analysis" in the Berkman Study's Figure 4.2 is in fact nothing more than a description of the relationship between two sets of variables, from which no conclusions about causality (let alone policy) can appropriately be drawn.

B. The Berkman Study Mischaracterizes the Evolution of U.S. Broadband Policy

95. The Berkman Study is being offered at a time when the Commission and the National Telecommunications and Information Administration (NTIA) are developing a broadband plan. At the same time, the FCC is considering new rules governing "network neutrality" on broadband networks. We are not aware, however, that the FCC is planning to revisit the rules that it has established to implement the network access requirements in the 1996 Telecommunications Act. Yet, the Berkman Study is openly critical of the evolution of these rules, seeing them as a reflection of incumbent "resistance" and "skeptical" courts.Footnote 96 In the course of its criticism, the Berkman Study mischaracterizes the evolution of U.S. policy towards unbundling.

96. At one point, the United States had the most ambitious and aggressive unbundling policy among the OECD countries. In implementing the 1996 Act, the FCC decided to require incumbents to unbundle every network element, not just the "local loop" that connects the subscriber to the carrier's wire center. Indeed, the incumbents were required to offer all of these elements as an "unbundled network element platform" or UNE-P at regulated rates based on forward-looking costs. No other country required such a wholesale offering. In addition, the FCC required the incumbents to share their subscriber loops with entrants seeking to offer only broadband services through the higher frequencies on the loop. The incumbents would be left with the lower frequencies to offer traditional telephone service.

97. This aggressive unbundling policy was contested in the federal courts as inconsistent with the requirements of the 1996 Act. The DC Circuit Court of Appeals and the Supreme Court forced the FCC to revise its unbundling rules in several ways. First, the Supreme Court overturned the FCC's approach to unbundling as overly broad because the Commission had failed to consider whether an entrant could self-provision the various unbundled elements or acquire them from a third party and because the Commission had considered any increase in costs a source of "impairment" that, in turn, required access to unbundled elements at regulated prices.Footnote 97

98. Second, the DC Circuit reversed the FCC's rules on line sharing in United States Telecommunications Association v. FCC, 290 F.3d 415 (2002) because the Commission had failed to evaluate the effects of inter-platform competition. The FCC complied in 2003 by dropping the line-sharing requirement. However, entrants would still be able to lease the entire local loop –a requirement that remains in place today.

99. Third, the DC Circuit was also skeptical of the FCC's ruling that virtually every network element, including mass-market switching, had to be offered by incumbents to competitors at regulated rates. The Court instructed the Commission to examine whether the unbundling of switching was required in every geographic market given the investment in switching by many new competitors in many urban markets. When the FCC failed to drop the requirement for unbundling switching services in its revised rules in 2003, the DC Circuit once again instructed the FCC to reconsider in a strongly-worded opinion. (United States Telecommunications Association v. FCC, 259 F3d. 572 (2003)) As a result, in 2004 the FCC was forced to eliminate unbundling of mass-market switching and, therefore, the UNE-P. However, competitors could still lease, among other network elements, the copper loop at regulated rates if they wished to offer broadband and any other telecommunications services.

100. Thus, the Berkman Study is incorrect when it asserts that:

By the fall of 2001 a new FCC had changed course. Between that fall and the spring of 2002, the FCC passed a series of decisions that abandoned the effort to implement open access, and shifted the focus of American policy from the idea of regulated competition within each wire – competition over the copper plant of the telephone company and over the coaxial cable of the cable company – to competition between the owners of the two wires.Footnote 98

To the contrary, neither the FCC nor state regulators in the U.S. "abandoned" local loop unbundling in 2002 or at any time since then. Competitors may still lease the local loop at regulated rates. However, they do not have the right to share the loop at even lower regulated rates.

101. It is true, however, that as a result of these changes in U.S. policy, competitors' use of incumbents' unbundled network elements began to decline. A large share of this decline was due to the ending of the UNE-P caused by the FCC's decision to drop network switching from the list of required mandatory unbundled elements. These lines were not being used to offer broadband services, but rather to compete in the provision of traditional telephone services. Many entrants – including Covad, NorthPoint, Rhythms, and Net 2000 – had tried to offer DSL services over unbundled incumbent loops and even shared incumbent loops and had failed. Indeed, given the aggressive competition between cable companies and incumbent telephone companies in offering broadband, and despite the best efforts of state and federal regulators to create a favorable regulatory environment and low rates for unbundled elements, no U.S. broadband entrant that has relied on unbundled loops has been able to avoid bankruptcy.Footnote 99

102. The Berkman Study also presents an incomplete (and, as a result, misleading) discussion of the U.S. decision not to impose open access policies on cable broadband providers, implying that the FCC failed to actively consider imposing such rules on cable operators. As the Berkman Study tells it,

…around 1999-2000, as AT&T purchased major cable systems, a new question emerged – whether cable should be subject to the same kind of open access regulation. In several instances cable franchising authorities tried to do this; but the power to impose open access on cable operators was seen as residing in the FCC, not local authorities.Footnote 100

103. In fact, the FCC actively considered imposing open access as a merger condition at the time of the AT&T-TCI merger. After considering the matter, its Chairman at the time, William Kennard, explained the grounds for his decision to forego such a vast expansion of open access regulation onto the cable pipe. As he said in a September 1999 speech,

It is easy to say that government should write a regulation, to say that as a broad statement of principle that a cable operator shall not discriminate against unaffiliated Internet service providers on the cable platform. It is quite another thing to write that rule, to make it real and then to enforce it…. So, if we have the hope of facilitating a market-based solution here, we should do it, because the alternative is to go to the telephone world, a world that we are trying to deregulate and just pick up this whole morass of regulation and dump it wholesale on the cable pipe. That is not good for America.Footnote 101

C. The Berkman Study Mischaracterizes the Policy Consensus Abroad

104. The Berkman Study also goes out of its way to characterize foreign views of unbundling, seeking to present a picture of virtual unanimity among foreign regulators about unbundling's virtues, with the U.S. (along with a few others) as "recalcitrant" outliers.

105. While it is undeniably true that unbundling has played a larger role in some other countries than in the U.S., the reason for this result is not – as the Berkman Study suggests – because their regulators agree that intramodal competition (supported by unbundling) is generally superior to intermodal competition. To the contrary, there is a wide and deep consensus that conditions among and within countries vary widely, and that intermodal competition is superior wherever it is possible.

106. Consider, for example, the June 2009 report of the European Regulators Group (ERG),Footnote 102 which is cited numerous times by the Berkman Study for the proposition that foreign regulators support the unbundling of broadband networks. In fact, the ERG Report emphasizes that economic conditions vary from country to country, that the "economic viability of roll-out strategies is largely influenced by specific local characteristics,"Footnote 103 and that "[o]verall, the country cases support the result … that there are significant differences between and within countries, which reflect differences in the economics of NGA networks, resulting from e.g. different densities or loop length but also from the relevance of competitive pressure from cable networks."Footnote 104

107. For example, the ERG Report finds with respect to Korea and Japan that "Due to the high population density and greater proportion of aerial cables… it is relatively cheap to deploy fibre in these countries."Footnote 105 The ERG also notes approvingly that "Outside of Europe, AT&T is rolling out a FttCab network and Verizon offers FttH in certain US cities. This is in part because of the poor quality of existing DSL services (due to long copper lines) and because of strong competition from cable operators."Footnote 106

108. While the ERG Report acknowledges that various factors affect broadband penetration and investment, and that these factors vary across countries, it is unambiguous in its support for infrastructure competition, finding that "Competition, in particular infrastructure competition, promotes investment as can be seen in countries with high cable penetration. Regulation should set the framework in such a way that it promotes competition."Footnote 107 Thus, "Where it is practically and economically feasible to promote infrastructure based competition, this should be the aim of national regulatory authorities (NRAs)."Footnote 108

109. The Berkman Study does not stop, however, at mischaracterizing foreign regulators' opinions: It also mischaracterizes their actions. For example, at page 76, the Berkman Study lists as a core finding that "Access rules are now being applied to the next generation transition, particularly to fiber," and cites the ERG Report in support of this conclusion. In fact, however, the ERG Report states plainly that among European countries, "Unbundled fibre access is only available on regulated terms in the Netherlands."Footnote 109

Moreover, as noted above, the most recent ECTA and IDATE data show that the incumbent in the Netherlands (KPN) currently has no residential fiber loops to unbundle!

  2. 94 See (back to footnote reference 94)
  3. 95 The Berkman Study acknowledges that the U.S. has among the lowest "entry level" prices, and that this fact should lead to higher levels of penetration. It never reconciles this fact with its contention that penetration in the U.S. is low as a result of the absence of unbundling, which could only increase penetration to the extent it reduces prices. (back to footnote reference 95)
  4. 96 Berkman Study at 78. The Berkman Study's highly opinionated characterization of U.S. policy during the first decade of the 21st century is consistent with the previously expressed views of its principal investigator, Dr. Yochai Benkler, who (for example) has previously characterized the FCC's decision to classify cable modem service as an "information service" (a decision upheld by the Supreme Court in the Brand X case) as a "legally admissible policy error." See, Yochai Benkler, The Wealth of Networks (2006) at 400 (available at (back to footnote reference 96)
  5. 97 AT&T Corp. v. Iowa Utilities Board, 525 U.S. 366 (1999). ("The FCC cannot, consistent with the statute, blind itself to the availability of elements outside the incumbent's network. In addition, the FCC's assumption that any increase in cost (or decrease in quality) imposed by denial of a network element renders access to that element 'necessary,' and causes the failure to provide that element to 'impair' the entrant's ability to furnish its desired services, is simply not in accord with the ordinary and fair meaning of those terms.") (back to footnote reference 97)
  6. 98 Berkman Study at 82. (See also at 77: "Some form of open access regulation has at this point been adopted by every country in the OECD except the United States, Mexico, and the Slovak Republic (which has been in the process of passing unbundling requirements for over two years, but has not yet done so)." The Berkman Study then goes on to note that broadband penetration in both Mexico and the Slovak Republic is relatively low, apparently implying that there is a connection between low broadband penetration and the absence of unbundling in these countries. Yet, the Berkman Study provides no evidence whatsoever for this conclusion; to the contrary, its regression analysis of the determinants of broadband penetration suggests that penetration in these countries is explained by their relatively low incomes and population densities.)

Soumission (suite)

VI. Conclusions

110. In our opinion, for the reasons explained above, the Berkman Study does not constitute a sound foundation for decisionmaking by the Commission. The study is neither rigorous nor impartial, but instead presents a highly opinionated, and in many respects demonstrably incorrect, portrayal of the evidence as it relates to the effects of public policy on broadband penetration and other key indicators of performance in the broadband market. In particular, as we have demonstrated above, the weight of the evidence demonstrates that mandatory unbundling has reduced broadband penetration and deterred investment in broadband telecommunications infrastructure, and that mandatory unbundling of Next Generation infrastructures would have similar effects.

Exhibit B: Ehrlich Qualifications

Everett M. Ehrlich

Dr. Everett M. Ehrlich is one of the nation's leading business economists. His firm, ESC Company, combines economic analysis, business development, and communications skills to solve a wide range of business problems. ESC's diverse clientele have included leading firms in the financial, accounting, pharmaceutical, automotive, and other industries, and such diverse organizations as the Pew Center for Global Climate Change and the Major League Baseball Players Association. He also recently served as Executive Director of the CSIS Commission on Public Infrastructure under co-chairmen Felix Rohatyn and Warren Rudman; a bipartisan bill to enact their recommendations was introduced in the 110th Congress.

Dr. Ehrlich served in the Clinton Administration as Under Secretary of Commerce for Economic Affairs, the principal economic policy official for Commerce Secretaries Brown and Kantor and chief executive of the nation's statistical system. As such, he led the first comprehensive strategic review of the nation's economic statistics in four decades, leading to a major modernization of featured measures of the economy. He supervised the redesign of the 2000 decennial census. He co-chaired the White House working group on the restructuring of the U.S. economy in the face of information technology, was a leader in the U.S.' planning effort of the two G-7 "Jobs Summits," and oversaw the Administration's economic analysis of global climate change.

Prior to his service as Under Secretary, Dr. Ehrlich was Vice-President for Economic and Financial Planning, and for Strategic Planning, of Unisys Corporation, from 1988 to 1993. As such, he had responsibilities concerning corporate development and finance, formulating business strategy, and economic forecasting. He reported directly to two chairmen of the company. He has also been the Senior Vice-President and research director of the business-based think tank, the Committee for Economic Development.

Dr. Ehrlich earlier served as Assistant Director of the Congressional Budget Office, where he directed the CBO program in trade and technology, infrastructure and space transportation, energy and the environment, and agriculture. He joined CBO in 1977, after having served as a Legislative Aide to Congressman John Conyers, Jr., and having briefly taught economics at the university level.

Dr. Ehrlich is the author of two critically-acclaimed novels: Big Government (1998), and Grant Speaks (2000), both by Warner Books. He was, for eight years, a regular economics commentator on National Public Radio's Morning Edition, and his writings have appeared in The Financial Times, Investors Business Daily, The Christian Science Monitor, The Washington Post, The International Economy, The New York Review of Books¸ and other publications.

Dr. Ehrlich was born in New York City in 1950 and is a product of its public schools. He received a B.A. in 1971 from S.U.N.Y. Stony Brook and a Ph.D. in economics in 1975 from the University of Michigan. He lives with his family in Bethesda, Maryland, where he has coached little league, acted in children's theater, been wardrobe master for the high school chorus, and waits for the Washington Nationals to win the World Series.
