July 2011The Costs of Free Entry: An Empirical Study of Real Estate Agents in Greater Boston
with Parag A. Pathak: w17227
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 properties to sell, decreases the market share of experienced agents, and leads to a reduction in average service quality. These empirical patterns motivate an econometric model of the dynamic optimizing behavior of agents that serves as the foundation for simulating counterfactual market structures. A one-half reduction in the commission rate leads to a 73% increase in the number of houses each agent sells and benefits consumers by about $2 billion. House price appreciation in the first half of th...
November 2008Tracing the Woes: An Empirical Analysis of the Airline Industry
with Steven Berry: w14503
The U.S. airline industry went through tremendous turmoil in the early 2000's. There were four major bankruptcies and two major mergers, with all legacy carriers reporting a large profit reduction. This paper presents a structural model of the airline industry, and estimates the impact of demand and supply changes on profitability. We find that, compared with the late 1990s, in 2006, a) air-travel demand was 8% more price sensitive; b) passengers displayed a strong preference for direct flights, and the connection semi-elasticity was 17% higher; c) the changes of marginal cost significantly favored direct flights. These findings are present in all the specifications we estimated. Together with the expansion of low cost carriers, they explained more than 80% of the decrease in legacy carrie...

December 2003Estimating the Effects of Global Patent Protection in Pharmaceuticals: A Case Study of Quinolones in India
with Shubham Chaudhuri, Pinelopi K. Goldberg: w10159
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 prices for medicines, with adverse consequences for the health and well-being of their citizens. On the other hand, research-based global pharmaceutical companies, argue that prices are unlikely to rise significantly because most patented products have therapeutic substitutes. In this paper we empirically investigate the basis of these claims. Central to the ongoing debate is the structure of demand for pharmaceuticals in poor economies where, because health insurance coverage is so rare, almost all medi...
