In the paper we introduce technological comparative advantage and transaction costs into the Heckscher-Olin (HO) model and refine the HO theorem, the Stolper-Samuelson theorem, the Rybczynski theorem, and factor equalization theorem. The refined core theorems can be used to accommodate recent...

This paper shows that a 2 x 2 Ricardian model has a unique general equilibrium, and the comparative statics of the equilibrium involve discontinuous jumps. If partial division of labor occurs in equilibrium, the country producing both goods would impose a tariff, whereas the country producing a...

This paper introduces technological differences and transaction costs into the Heckscher-Ohlin (HO) model and examines the HO theorem, factor price equalization theorem, the Stolper-Samuelson theorem and the Rybczynski theorem. It shows that the HO theorem can be refined, and that the factor...

This paper develops a Ricardian model with transaction costs and endogenous and exogenous comparative advantages. It shows that the level of division of labour and trade increases as transaction conditions improve. It identifies the conditions for trade negotiations that result in zero tariff...

This paper develops a general equilibrium model with transaction costs and endogenous and exogenous comparative advantages. In the model, the governments are allowed to choose between tariff war, tariff negotiation, and laissez faire regimes. The model shows that the level of division of labor...

The paper introduces asymmetric production conditions between firms and asymmetric transaction conditions between countries into the Murphy-Shleifer- Vishny model of industrialization. It explores a general equilibrium mechanism that generates circular causation loop that each firm’s...

The paper introduces differences in production and transaction conditions between countries into a model of monopolistic competition. It applies inframarginal analysis to show that, as transaction conditions are improved, the general equilibrium may jump discontinuously across different patterns...
