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.
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
Reporting on cutting-edge advances in economics, this book presents a selection of commentaries that reveal the weaknesses of several core economics concepts. Economics is a vigorous and progressive science, which does not lose its force when particular parts of its theory are empirically invalidated; instead, they contribute to the accumulation of knowledge. By discussing problematic theoretical assumptions and drawing on the latest empirical research, the authors question specific hypotheses and reject major economic ideas from the “Coase Theorem” to “Say’s Law” and “Bayesianism.” Many of these ideas remain prominent among politicians, economists and the general public. Yet, in the light of the financial crisis, they have lost both their relevance and supporting empirical evidence. This fascinating and thought-provoking collection of 71 short essays written by respected economists and social scientists from all over the world will appeal to anyone interested in scientific progress and the further development of economics.
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.
When a giant invades the peaceful kingdom of the Tatrajanni and takes the different-looking girl prisoner, it takes the combined efforts of the wise woman of the mountain, the Prince, and the girl herself to rid the kingdom of the intruder.
This updated and expanded 1985 edition of the classic 1974 work covers deindustrialisation, industrial and competition policy, the public enterprise sector, regional and urban policy, and privatisation, as well as focussing on the firm and the industrial sector in all its facets. It remains the key work on industrial economics.
