Abstract We use a dynamic international trade model to analyse the implications of international trade for agents’ preferences and economic growth. This model is based on the home market effect with external habit formation (“catching up with the Joneses”) and “learning by doing” in production. We demonstrate the following: the historical composition of consumption in countries determines industrialization after trade; the preferences of agents converge after trade, independent of the economic results; and the welfare effects of trade may be positive or negative depending on trading partner characteristics. In some scenarios, autarky is strictly preferred to trade. Thus, international trade does not necessarily imply greater welfare, as is the typical result in a static context under CES preferences.

国际贸易与“赶超”：消费模式是否趋同？

摘要 我们使用动态国际贸易模型来分析国际贸易对代理人偏好和经济增长的影响。该模型基于国内市场效应，在生产中形成外部习惯（“赶上邻居”）和“边做边学”。我们证明以下几点：各国消费的历史构成决定了贸易后的工业化；代理人的偏好在交易后收敛，与经济结果无关；贸易的福利影响可能是正面的，也可能是负面的，这取决于贸易伙伴的特征。在某些情况下，自给自足绝对是交易的首选。因此，国际贸易并不一定意味着更大的福利，这是 CES 偏好下静态背景下的典型结果。
