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...

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....

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.

Broadband is becoming increasingly important to national economies and the personal lives of users. However, broadband availability and adoption are not diffusing in rural and urban areas at the same rates. This article updates the rural broadband digital divide, with special attention paid to...

The newest dimension of the digital divide is access to broadband (high-speed) Internet service. Using comprehensive U.S. data covering all forms of access technology (chiefly DSL and cable modem), I look for evidence of unequal broadband availability in areas with high concentrations of poor,...

I develop a new approach for sample selection problems that allows parametric forms of any type to be chosen for both for the selection and the observed variables. The Generalized Parametric Selection (GPS) model can incorporate both duration and count data models, unlike previous parametric...
