The focus of this thesis is on issues of empirical industrial organization. Specifically, I utilize tools and ideas from Industrial organization to study areas of health and history. In Chapter 1, I examine the relationship between how hospital ownership is organized and the intensity of competition in the US health care market. I study the question using an empirical entry model. These models typically exhibit multiple equilibria. To resolve this problem, a novel algorithm that computes all the equilibria of the game is developed. My findings suggest that for-profit and not-for-profit hospitals can be regarded as supplying differentiated products. I also find evidence suggesting that markets that have both types of hospitals enjoy a higher level of health care services. Chapter 2 is coauthored with Eugene Choo. In this chapter, we investigate the variation of winning bids in slave auctions held in New Orleans from 1804 to 1862. Specifically, we measure the variation in the price of slaves conditional on their geographical origin. Previous work using a regression framework ignored the auction mechanism used to sell slaves. This introduces a bias in the conditional mean of the winning bid. Unfortunately, the number of bidders is unobserved by the econometrician. We adopt the standard framework of a symmetric independent private value auction and propose an estimation strategy to overcome this bias. We find the number of bidders had a significant positive effect on the average winning bid. The price variation according to the geographical origin of slaves found in earlier work continued to persist after accounting for the omitted variable. Chapter 3 is coauthored with Henry Overman, Diego Puga, and Matthew Turner. In this chapter, we study the relationship between urban sprawl and obesity. Using data that tracks individuals over time, we find no evidence that urban sprawl causes obesity. We show that previous findings of a positive relationship most likely reflect a failure to properly control for the fact the individuals who are more likely to be obese choose to live in more sprawling neighborhoods. Our results indicate that current interest in changing the built environment to counter the rise in obesity is misguided.
Essays on Microeconomics and Industrial Organisation aim to serve as a source and work of reference and consultation for the field of Microeconomics in general and of Industrial Organisation in particular. Traditionally, Microeconomics is essentially taught as theory and hardly ever an estimation of a demand, production and cost function is offered . Over the last two decades, however, Microeconomics has greatly broadened its field of empirical application. Therefore, this text combines microeconomic theories with a variety of empirical cases. The standardised microeconomic analysis of demand, production and costs is set forth along with appropriate econometric techniques. The text consists of four parts: Demand, Production and Costs (Supply), Market and Industrial Structure and Failure of Market and Industrial Regulation. It includes eleven new chapters with respect to the first edition.
Empirical Studies in Industrial Organization brings together leading scholars who present state-of-the-art research in the spirit of the structure-conduct-performance paradigm embodied in the work of Leonard W. Weiss. The individual chapters are generally empirically or public policy oriented. A number of them introduce new sources of data that, combined with the application of appropriate econometric techniques, enable new breakthroughs and insights on issues hotly debated in the industrial organization literature. For example, five of the chapters are devoted towards uncovering the link between market concentration and pricing behavior. While theoretical models have produced ambiguous predictions concerning the relationship between concentration and price these chapters, which span a number of different markets and situations, provide unequivocal evidence that a high level of market concentration tends to result in a higher level of prices. Three of the chapters explore the impact of market structure on production efficiency, and three other chapters focus on the role of industrial organization on public policy. Contributors include David B. Audretsch, Richard E. Caves, Mark J. Roberts, F.M. Scherer, John J. Siegfried and Hideki Yamawaki.
Conventional economic analysis of property rights in natural resources is too narrow and restrictive to allow for effective comparisons between alternative institutional structures. In this book, a conceptual framework is developed for the analysis of the
Written solely for the undergraduate audience, Industrial Organization: Theory and Practice, which features early coverage of Antitrust, punctuates its modern introduction to industrial organization with relevant empirical data and case studies to show students how to apply theoretical tools.
Applied Industrial Organization offers a perspective on the richness of empirical industrial organization studies. Some papers derive empirical implications from theoretical models, but other papers start from empirical evidence and construct a theory. Three major topics are explored: the role of innovation, the evolution of market structure and firms, and the determinations of performance. As the central force of market economies, innovation is the essence of competition and results in changes to market structures. Other forces driving the evolution of markets and firms are also analyzed. Finally, the determinants of profitability are investigated. In particular, characteristics such as price flexibility, successful lenders and monopoly regulation are examined. Contributors include F.M. Scherer, Paul Geroski, John Hey, David Audretsch, Manfred Neumann, among others.
