Abstract:	In this paper we evaluate scale efficiency patterns of local operating companies in the US telecommunications industry. Scale efficiency is defined as the ability of each company to operate as close to its most productive scale size as possible, and is calculated using data envelopment analysis. The analysis of scale efficiencies is conducted for a set of 39 local operating companies, over six time periods: 1975, 1978, 1981, 1984, 1987 and 1990. During these time periods, several technical and institutional changes took place in the industry which are likely to have had an impact on the abilities of the companies to exploit feasible scale efficiencies, and we find that scale efficiencies have steadily increased over these time periods. We also establish that the Bell operating companies are no different from the independent companies in their ability to be scale efficient; single-state firms are relatively more scale efficient; line digitization, during the periods studied, has not significantly impacted scale efficiency; and firms belonging to multi-company parents are more scale efficient. Additionally, policy regime changes, such as the introduction of intra-LATA toll market competition and incentive regulation schemes, have positively impacted firms` abilities to attain scale efficiency, while micro-segment competition in local markets have, so far, not had the expected impact.
