Legal enforcement of bans on goods can reduce the size of the black market but lead to greater violence by increasing revenue in the illicit market. However, the link between enforcement and violence is not as simple as is suggested by the textbook model, even for a competitive market....

I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the United States. An interim of lighter regulation provides an "experiment" to test the regulatory regime's impact. The econometric model comprises an arrival process (for...

Our study extends the empirical literature on whether vertical restraints are anticompetitive. We focus on exclusive contracting in platform markets, which feature indirect network effects and thus are susceptible to applications barriers to entry. Theory suggests that exclusive contracts in...

The effects that regulation has on the innovation and the introduction of new telecommunications services have not been previously quantified in the literature. This study compares state-regulated services in Indiana under rate of return regulation (RoRR) and under alternative regulation. The...

This paper develops and compares specification tests for parametric duration models estimated with censored data. The tests are based on generalized residuals (the integrated hazard), which is exponentially distributed if the model is correctly specified. I present several conditional moment...

We explore the indirect network effect in the market for home video games. We examine the video game console makers’ strategic choice between increasing demand by lowering console price and by encouraging the growth of software variety. We also explore the existence of an applications barrier...
