We document the numerical challenges we experienced estimating random-coefficient demand models as in Berry, Levinsohn, and Pakes (1995) using two well-known data sets and a thorough optimization design. The optimization algorithms often converge at points where the first- and second-order...

The use of incentive regulation and other alternative regulatory programs in U.S. electricity markets has grown during the past two decades. Within a stochastic frontier framework, I investigate the effect of individual programs on the technical efficiency of a large set of coal and natural gas...

Prior to the Telecommunications Act of 1996, many U.S. states restructured their regulatory framework by replacing rate-of-return regulation with competition in both the local exchange service and local long-distance markets and adopting price regulation (price caps and price freezes). Using a...
