Observable versus unobservable R&D investments in duopolies

Journal of Economics - We study a quantity-setting duopoly with homogeneous products in which two firms first make their cost-reducing R&D investments, and then compete in quantities. When...     

The impacts of PTA formation on small economies’ tax competition for FDI inflows

This paper examines why small economies are so eager to form or join preferential trade agreements (PTAs), as observed in the East Asia and the Central Europe, taking consideration of the strategic impacts of PTA formation on tax competition for foreign direct investment (FDI) inflows. Based on a simple model where three asymmetric countries compete for FDI inflows, we demonstrate that PTA formation provides a strategic advantage to a small member country of PTA in competing for FDI inflows not only with respect to a non-member country but with a large member country when the integrated market size is large enough. In addition, it is shown that it might be an out-of-equilibrium path strategy for a non-member small economy to exert efforts to induce FDI inflows, because the excessive subsidies to induce FDI inflows might outweigh the gains from the FDI inflows due to strategic disadvantage in tax competition after PTA formation. These findings explain why small economies are mainly driven by the expected economic benefits including FDI inflows from joining PTA.     

Welfare effects of competitive lobbying efforts in international oligopoly markets

Conventionally, rent-seeking activities have been considered to deteriorate social welfare and to distort resource allocation. This paper examines whether rent-seeking behavior can improve social welfare by focusing on the welfare effects of firms’ competitive lobbying efforts when governments can impose market entry regulation against foreign firms. We demonstrate that competitive lobbying efforts can improve social welfare when such lobbying efforts are directed to reduce market entry barriers. In addition, social welfare can be maximized when the government shows the maximum sensitivity to the foreign firm's political contributions while maintaining competitive market structure. Moreover, it is shown that the dominant strategy for a domestic firm is to allocate more resources to R&D sectors while it is optimal for foreign firms is to exert more efforts in lobbying to reduce the market entry barriers when a government makes political economic approach in market entry regulations.
