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

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...

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...
