This paper investigates the environment tax and trade liberalization with different market structures (pure oligopoly or mixed oligopoly) juxtaposing the substitutability of the goods (homogenous goods and differentiated goods), wherein environmental damage is associated with consumption. It...

This paper compares the optimal tariff and revenue maximizing tariffs in the presence of partial privatization. We show that in an international mixed oligopoly with asymmetric costs and partial privatization, when the marginal cost of the privatized firm exceeds a critical value, maximum...

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 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...

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...

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.
