The US airline industry went through tremendous turmoil in the early 2000s, with four major bankruptcies, two major mergers, and various changes in network structure. This paper presents a structural model of the industry and estimates the impact of demand and supply changes on profitability....

In this paper, we consider the empirical problem of estimating the underlying profit function of firms from “revealed choice” data on entry in a cross-section of oligopoly markets. One problem faced in the earlier literature is the problem of multiple equilibrium, which makes traditional...

This paper studies the real estate brokerage industry in Greater Boston, an industry with low entry barriers and substantial turnover. Using a comprehensive dataset of agents and transactions from 1998-2007, we find that entry does not increase sales probabilities or reduce the time it takes for...

Under the TRIPS agreement, WTO members are required to enforce product patents for pharmaceuticals. The debate about the merits of this requirement has been extremely contentious. Many low income economies claim that patent protection for pharmaceuticals will result in substantially higher...

Corn prices increased sharply in the summer of 2012 due to expected production shortfalls in the United States, which produces roughly 40% of the world's corn. A heat wave in July adversely affected corn production. We extend earlier statistical models of county-level corn yields in the Eastern...

It is well documented that, in the presence of substantial fixed costs, markets offer preference majorities more variety than preference minorities. This fact alone, however, does not demonstrate the market outcome is in any way biased against preference minorities. In this paper, we clarify the...

The recent financial crisis in Indonesia has resulted in dramatic price increases. Using very recent data, we investigate whether these price increases have impacted the cost-of-living of poor households in a disproportionately harsh way. We find that the poor have indeed been hit hardest. Just...

We consider nonparametric identification in models of differentiated products markets, using only market level observables. On the demand side we consider a nonparametric random utility model nesting random coefficients discrete choice models widely used in applied work. We allow for...

This paper considers the likely effect on the automobile industry of a free trade agreement between the U.S. and Mexico. As there are currently large restrictions on imports into Mexico, one important outcome of a free trade agreement would be the opening of the Mexican market to U.S. producers....

This paper estimates a model of airline competition that captures the two major features of the industry: product differentiation and economies of density. The results not only provide support to some of the traditional common wisdom in the industry, but are also useful for understanding major...
