These are reproduced in table A-3 for the various measures of UNE-P.2 The results in table A-3 are shown for several measures of the UNE-P rate across states. Despite the fact that this is a regulated price, no one can agree on what the price is at any point in time. I estimate these regressions for one measure published by Anna Maria Kovacs and Kristin Burns, four published by Billy Jack Gregg, and one by Hassett and his colleagues. 3 The last study was funded by AT&T and therefore undoubtedly contains UNE-P data from AT&T, the same source used by Willig and associates. Note that the significant, negative coefficient on the UNE-P rate variable for some of the regressions involving 1996-99 capital expenditures becomes insignificant for 2000-03 capital spending when the Kovacs and Burns Estimates of Bell Company Cumulative Expenditures Table A-3.
