本文研究了具有CES型上层效用函数的张伯林-李嘉图模型中的交易模式和交易收益。结果表明，在自由贸易条件下出现了强烈的完全专业化倾向，从各国福利的角度来看，自由贸易比自给自足更可取。本文还考虑了被称为半自给自足的贸易制度，在这种制度下，一个部门处于自由贸易之下，而另一个部门处于关闭状态。分析表明，如果消费中的跨部门替代是有弹性的，那么自由贸易不一定会在所有国家获得比半自给自足更高的福利。
This paper investigates trade patterns and the gains from trade in a Chamberlinian-Ricardian model with a CES type of upper-tier utility function. It is shown that a strong tendency toward complete specialization emerges under free trade and that free trade is preferable to autarky from the viewpoint of each country’s welfare. This paper also considers the trade regime called semi-autarky, in which one sector is under free trade, while the other is closed. The analysis demonstrates that free trade does not necessarily attain higher welfare in all countries relative to semi-autarky if cross-sector substitution in consumption is elastic.
