Prior studies suggest that, with elastically supplied inputs, free entry may lead to an inefficiently high number of firms in equilibrium. Under input scarcity, however, the welfare loss from free entry is reduced. Further, free entry may increase use of high-quality inputs, as oligopolistic...

The main purpose of this paper is to estimate an equilibrium model of private and public school competition that can generate realistic pricing patterns for private universities in the U.S. We show that the parameters of the model are identified and can be estimated using a semi-parametric...

It is well recognized by economists that long-term contracting under an array of price and non-price provisions may be an efficient response to small-numbers bargaining problems. Empirical work to distinguish such issues from predictions of models of market power and bargaining has been sparse,...

Non-competitive conduct can be assessed by estimating the size of the markup or Lerner index achieved in a market. The markup implies a price elasticity of demand faced by the representative firm. For a given markup, non-competitive conduct is greater the more elastic is the market elasticity of...

We describe changes over time in inequality in postsecondary education using nearly seventy years of data from the U.S. Census and the 1979 and 1997 National Longitudinal Surveys of Youth. We find growing gaps between children from high- and low-income families in college entry, persistence, and...

Theory suggests that bank integration (financial integration generally) can magnify or dampen the business cycles, depending on the importance of shocks to firm collateral versus shocks to the banking sector. In this paper, we show empirically that bank integration across U.S. states over the...

We examine the impact of loss of U.S. patent exclusivity (LOE) on the prices and utilization of specialty drugs between 2001 and 2007. We limit our empirical cohort to drugs commonly used to treat cancer and base our analyses on nationally representative data from IMS Health. We begin by...

We examine the evolving structure of the U.S. hospital industry since 1970, focusing on how ownership form influences entry and exit behavior. We develop theoretical predictions based on the model of Lakdawalla and Philipson, in which for-profit and not-for-profit hospitals differ regarding...

The view that the strength of the dollar in the early 1980s was associated with persistent restructuring of United States industry is supported by correlations between exchange rate patterns and data on business formation, business failure and sectoral investment in new plant and equipment....

We examine whether and to what extent consolidation in the U.S. health insurance industry is leading to higher employer-sponsored insurance premiums. We make use of a proprietary, panel dataset of employer-sponsored healthplans enrolling over 10 million Americans annually between 1998 and 2006...
