Roughly one half of hospitals in the U.S. are in rural areas, yet researchers have largely studied the effects of hospital ownership in the urban context. We examine differences in the provision of profitable and unprofitable medical services in rural areas across nonprofit, for-profit, and...

Precision medicines inherently fragment treatment populations, generating small-population markets, creating high-priced "niche busters" rather than broadly prescribed "blockbusters". It is plausible to expect that small markets will attract limited entry in which a small number of...

Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct-firm price competition with nested CES or nested logit demands. We show that the Herfindahl index provides an adequate measure of the welfare distortions introduced by market power, and that the induced...

We present a dynamic quantity setting game, where players may continuously adjust their quantity targets, but incur convex adjustment costs when they do so. These costs allow players to use quantity targets as a partial commitment device. We show that the equilibrium path of such a game is...

The majority shareholder in a closely held corporation may use its control of the corporate machinery to appropriate wealth from the minority, and it is difficult for the majority to make a binding commitment not to do so. This paper models the interaction between majority and minority...

We show that industrial ownership structures, such as keiretsu groupings in Japan, may significantly impact firms' incentives to engage in FDI. While the previous literature has mainly focused on the cost of capital advantages enjoyed by keiretsu firms, this paper examines two relatively...
