We show that the number of merger proposals (frequency-based deterrence) is a more appropriate indicator of underlying changes in merger policy than the relative anti-competitiveness of merger proposals (composition-based deterrence). This has strong implications for the empirical analysis of...

Our concern is with a firm-specific industrial policy. When R&D subsidies or taxes are differentiated among firms, the question arises which firms in an industry should receive such support. We analyze a situation where firms differ in their R&D technologies in two distinct ways: They differ...

This paper explores the relationships between the growth in the medical workforce in an aging society and employment in other sectors of the economy, based on data from the United States since 1985. Employment in medical services grew, but did not displace employment in other sectors uniformly....

This informal paper explores models of competitive insurance market equilibrium when individuals of initially similar apparent risk experience divergence in risk levels over time. The information structure is modeled in three alternative ways: all insurers and insureds know risk at any point in...
