In this analysis we examine the market entry patterns of new local telephon
e companies. We construct and estimate a multinomial logit model using info
rmation describing numbering code distribution within local telephone marke
ts and the associated income, density, and regulatory characteristics of th
ese markets. Our findings support the conventional wisdom that facilities-b
ased entry by new local competitors is more likely to occur in large urban
telephone markets. In addition, we present evidence that, with the exceptio
n of territories served by Ameritech, entry is more likely to occur in Bell
Operating Company service territories.
