ns Industry Broadband Deployment, Hearings before the U.S. Senate Commerce Committee, 107 Cong. 2 sess. (Government Printing Office, 2002). Notes to Appendix 1. The Reg variables are dummy variables reflecting the nature of regulation in each state. In addition, I use dummy variables for each Bell company to capture any company- specific effects. 2. The detailed results for all regressions are available from the author. 3.

In addition to the regression results reported in table 5-7, I estimated twelve separate regressions of annual RBOC capital expenditures in each of four years-2000, 2001, 2002, and 2003-on the exogenous variables shown in table A-1, excluding UNE-P but using the Notes to Page 178 FCC data on CLEC share for each of three years, 2001, 2002, and 2003. I estimated another twelve separate regressions for only those states (thirty-four) for which the FCC reported CLEC share data in every year for 2001-03. Thus twenty-four regressions were estimated in toto. The coefficients for the CLEC share variable were positive in nineteen cases and negative in five cases. Of the nineteen positive coefficients, only two were statis- tically significant at the 5 percent confidence level and another three at the 10 percent level. Index Access charges.
