Our study extends the empirical literature on whether verticalrestraints are anticompeti-tive. We focus on exclusive contracting inplatform markets, which feature indirect net-work effects and thus aresusceptible to applications barriers to entry. Theory suggests thatexclusive contracts in...

Cell phone use is increasing worldwide, leading to a concern that cell phone use while driving increases accidents. Several countries, three states and Washington, D.C. have banned the use of hand-held cell phones while driving. In this paper, we develop a new approach for estimating the...

This empirical examination compares product innovation under price caps and Rate of return regulation (RoRR) in US telecommunications. The econometric model comprises a count process (for product innovation) followed by a duration process (for regulatory delay). More services were created under...

Three goals of the 1996 Telecommunications Act are competition, efficiency, and explicit mechanisms to further universal service. The new universal service policies violate these goals. I review the policies (support for highcost and rural areas, low-income subscribers, and educational and...

The performance of auxiliary regression-based specification tests for parametric duration models estimated with censored data is evaluated. The test using asymptotic critical values has poor size. Bootstrapping corrects the size problem but results in a biased power curve.

This study's estimates of the reduction in accidents from a ban on cell phone use while driving are both lower and less certain than previous studies indicate.
