摘要：

Several numerical model experiments are used to contrast computable general equilibrium (CGE) models explicitly incorporating imperfect competition with on the one hand 'textbook' comparative-advantage models and on the other hand competitive models based on the Armington approach. Imperfect competition has significant effects on inter-industry trade and welfare effects of trade liberalization. Less aggressive competition reduces elasticities of equilibrium quantities so that comparative advantage is not fully exploited. The Armington approximation is found to be a poor substitute for explicit incorporation of oligopolistic interaction and product differentiation at the firm level. © 1990.
