Although regulatory authorities are putting more emphasis to the long-run effects of mergers and acquisitions due to their effects on innovation, several merger proposals have been challenged due to their adverse innovation effects. In a simple model with endogenous R&D investment, we show that...

We show a new way through which patent protection affects innovation. We show that patent protection may reduce the final goods producers' incentives for innovation in industries with imperfectly competitive input markets. The input market structure may play an important role in this respect.

We show that the relationship between higher productivity of the foreign firm and host country welfare depends on the reason for foreign direct investment (FDI). If the reason for FDI is to get the advantage of cheap labor, higher productivity of the foreign firm may reduce host-country welfare....

Assuming linear demand and unit transportation cost, Head and Ries (2003, 'Heterogeneity and the FDI versus export decision of Japanese manufacturers', Journal of the Japanese and International Economies) conclude that the theoretical prediction of Helpman et al. (2004, 'Export versus FDI with...

We show the impact of technology licensing on optimal patent policy. Strong patent protection that eliminates imitation may not be the equilibrium outcome in the presence of licensing. Depending on the cost of innovation, licensing may either increase or reduce the strength of the patent protection.

We consider the welfare effect of cross-border merger in presence of international R&D competition. Cross-border merger increases domestic welfare if the bargaining power of the foreign firm and the slope of the marginal cost of R&D are sufficiently low. Otherwise, domestic welfare is lower...

Considering Cournot competition, this note shows that, if the firms differ in labor productivities, the equilibrium wage rates under a centralized labor union are not independent of the number of firms and product differentiation if the labor union charges a uniform wage rate. However, if the...

This paper considers welfare effects of entry when the incumbent firm behaves like a Stackelberg leader in the product market. In contrast to the existing literature, we show that entry may increase welfare for any cost asymmetries between the firms. Using a general demand function we show the...

We show that the relationship between higher productivity of the foreign firm and host country welfare depends on the reason for foreign direct investment (FDI). If the reason for FDI is to get the advantage of cheap labor, higher productivity of the foreign firm may reduce host-country welfare....

We show that if patent protection and trade secrecy generate asymmetric market structure, an innovator may prefer patent protection than trade secrecy even if the diffusion probability is higher under the former but it increases market concentration by preventing some imitators. So, whether an...
