本文研究了消费网络外部性存在下的贸易自由化效应。该框架适用于网络产品的选择，并对全球化与文化的争论提供了启示。在扩展的李嘉图国际贸易模型中，本文证明了：(1)如果自由贸易均衡是唯一的，贸易不次于自给自足；（ii）在自由贸易条件下，如果两国都是多样化的（网络竞争），贸易并不优于自给自足，但如果两国都是同质化的（网络垄断），贸易可能优于自给自足；（iii）当多个自由贸易均衡存在时，如果一个国家在自给自足的情况下是同质的，那么这个国家的每个人都可能从自由贸易中损失。在贸易自由化中，进口网络商品的消费者往往获利，而出口网络商品的消费者往往亏损。
This paper studies the effects of trade liberalization in the presence of consumption network externalities. The framework is applicable to the choice of network products and sheds light on the debate on globalization and culture. In an extended Ricardian model of international trade the paper shows that: (i) trade is not Pareto inferior to autarky if the free trade equilibrium is unique; (ii) trade is not Pareto superior to autarky if both countries are diverse (network competition) under free trade, but can be if each country is homogenous (network monopoly); (iii) and when multiple free trade equilibria exist everybody in a country can lose from free trade if that country is homogenous under autarky. Consumers of imported network goods tend to gain, while consumers of exported network goods tend to lose from trade liberalization.
