This paper studies a Ricardian model of international trade with a continuum of products in a general equilibrium model in which firms engage in oligopolistic competition. It provides a bridge between trade models based on perfect competition and models based on imperfect competition. Compared...

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...

The impact of international trade on a firm’s degree of specialization and income distribution is studied in a general equilibrium framework in which firms engage in oligopolistic competition. International trade increases a firm’s degree of specialization, but the number of goods a country...

The presence of circular causality in a region through factor returns is studied in a general equilibrium model in which firms producing final products engage in oligopolistic competition. The intermediate input is produced by capital and labor with a constant returns to scale technology. If the...

The impact of financial integration and product market integration is studied in a general equilibrium model with increasing returns in both the manufacturing sector and the financial sector. Firms engage in oligopolistic competition. An increase of the degree of competition in the financial...
