A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

We show that, on average, product market competition acts as a disciplining force constraining managers from misreporting accounting information. Further, in a quasi-natural experiment that uses shifts in import tariffs to identify intensification of competition, difference-in-difference...

How should multilateral trade policy be designed in a world in which countries differ in terms of market access and technology, and firms with market power differ in terms of productivity? We answer this question in a model of monopolistic competition in which variable markups increasing in firm...

In this study, we examine the nature of Schumpeterian competition between entrants and incumbents. We argue that incumbents may respond to the threat of entry by either attacking the entrant or trying to learn from it, and that entrants, in turn, may react by either reciprocating the incumbent's...

This analysis introduces a theoretical framework for assessing the empirical discussion of asymmetric information amongst mortgage lenders and adds the idea of lender competition into this framework. Despite this addition, the results are generally consistent with existing empirical findings...

We consider licensing with a patent competition for a non-drastic process innovation among firms competing in a Cournot market. We study whether licensing improves social welfare, after taking rent dissipation into account. For licensing auction, welfare worsens for minor innovations and...

There is not a day goes by without a passionate debate concerning Big Tech companies; while the main concern of governments seems to be related to social justice, a growing worry is associated with the consequences that large firms have on consumer welfare; nowadays these big entities engage in...

The nature, and normative properties, of competition in health care markets has long been the subject of much debate. In this paper we consider what the optimal benchmark is in the presence of moral hazard effects on consumption due to health insurance. Intuitively, it seems that imperfect...

We describe a computerized experiment which can be used to introduce students to imperfect competition in courses on Introductory Economics, Industrial Organization, and Strategy & Management. In addition to introducing students to strategic thinking in general, the experiment serves to...
