Abstract
This study analyzes the merger effects for 25 Incumbent Local Exchange Carriers over the period 1996–2005 using stochastic frontier analysis with a time-varying inefficiency model. We further conduct a comparison of results between the stochastic frontier analysis and the Malmquist index method. The empirical results indicate that the sample of telecommunications firms has experienced deterioration in average productivity growth following mergers. Significantly, both approaches suggest that firms that do not merge underperform in terms of average productivity growth.
