This paper provides a unified approach to study the influence of uncertainty and spillovers on the direction of R&D policy when firms engage in international R&D competition. When the reward to the winner is exogenously given, it is shown that whether a government will tax or subsidize its firm...

This paper studies the implications of international trade in a general equilibrium model in which the returns to scale are internal and firms choose their production technologies. The production function generated from internal increasing returns and the choice of technology leads to the...

This paper studies impacts of factor endowment on international trade in a general equilibrium model in which firms choose their technologies endogenously. Though countries only differ in factor endowment ex ante, countries may also differ in their chosen technologies. If industries choose...

This paper studies the impact of international trade in a general equilibrium model in which heterogeneous firms engage in oligopolistic competition. An increase of the size of the market leads to a decrease of the equilibrium price and an increase of per capita consumption. The opening of...

The impact of international trade is studied in a general equilibrium model in which firms engage in oligopolistic competition and linkage effects are present. Results are derived analytically. If countries have the same technologies and the same labor endowment, core-periphery pattern arises...

This paper studies the implications of international trade in a general equilibrium model in which the returns to scale are internal and firms choose their production technologies. The production function generated from internal increasing returns and the choice of technology leads to returns to...

This article studies the determinants of a firm's organizational form in the context of an imperfectly competitive industry. There are two kinds of organizational forms: the multidivisional form (M-form) and the unitary form (U-form). An M-form firm suffers from ignorance of demand externalities...

In this general equilibrium framework, the transportation sector is modeled as a distinct sector with increasing returns. A more advanced technology has a higher fixed cost but a lower marginal cost of production. Even with both manufacturing firms and transportation firms engaged in...
