We develop a competitive search model involving multiple regions, geographically mobile work- ers, and moving costs. Equilibrium mobility patterns are analyzed and characterized, indicating that shocks to a particular region, such as a productivity shock, can propagate to other regions through...

This paper investigates the impacts of progressive trade openness, technological externalities, and heterogeneity of individuals on the formation of entrepreneurship in a two-country occupation choice model. We show that trade opening gives rise to a non-monotonic process of international...

We investigate the incentive and the welfare implications of a merger when heterogeneous oligopolists compete both in process R&D and on the product market. We examine how a merger affects the output, investment, and profits of firms, whether firms have merger incentives, and, if so, whether...
