This study explores the possibility that local market power influences the observed asymmetric relationship between changes in wholesale gasoline costs and changes in retail gasoline prices. I exploit an original data set of weekly gas station prices in Southern California from September 2002 to May 2003, and take advantage of detailed station and local market level characteristics to determine the extent to which spatial differentiation influences price response asymmetry. I find that brand identity, proximity to rival stations, bundling and advertising, operation type, and local market features and demographics each influence a station's predicted price-response asymmetry.

Economic Models for Industrial Organization focuses on the specification and estimation of econometric models for research in industrial organization. In recent decades, empirical work in industrial organization has moved towards dynamic and equilibrium models, involving econometric methods which have features distinct from those used in other areas of applied economics. These lecture notes, aimed for a first or second-year PhD course, motivate and explain these econometric methods, starting from simple models and building to models with the complexity observed in typical research papers. The covered topics include discrete-choice demand analysis, models of dynamic behavior and dynamic games, multiple equilibria in entry games and partial identification, and auction models.

Although the airline, railroad, telecommunications, and electric power industries are at very different stages in adjusting to regulatory reform, each industry faces the same critical public policy question: Are policymakers taking appropriate steps to stimulate competition or are they turning back the clock by slowing the process of deregulation? This volume addresses that issue and identifies the next steps that policymakers should take to enhance public welfare in the provision of these services. Each chapter identifies the central policy issues that have arisen in each industry as it undergoes transformation to a deregulated environment. The authors reveal the flaws in the residual regulations and make the case for faster and more comprehensive deregulation. A concluding chapter identifies how interest groups continue to exert influence on regulatory agencies and on Congress, potentially undermining deregulation. The papers included here were initially presented in December 1999 at a conference sponsored and organized by the AEI–Brookings Joint Center for Regulatory Studies.
