本文的主要目的是描述现有文献中很少关注的几种情况下福利改善的条件。第一个目标是展示一个国家因政策从自给自足转向自由贸易而消除过剩供应所能获得的收益。第二个目标是描述向经济中引入新商品将产生福利收益的条件。讨论的第三个主要领域是将作者的方法论扩展到可以影响其贸易条件的大型开放经济体。用于说明消除过剩供应和引入新商品所带来的收益的技术具有更广泛的适用性；它们可用于从文献中获取和综合一些福利结果。
The primary purpose of the paper is to provide characterizations of the conditions for welfare improvements in several situations that have received very little attention in the existing literature. The first aim is to exhibit the gains that can accrue to a country from the elimination of excess supplies as a result of a policy move from autarky to free trade. The second aim is to characterize the conditions under which the introduction of new goods into the economy will generate welfare gains. The third main area discussed is the extension of the authors’ methodology to a large open economy that can influence its terms of trade. The techniques used to illustrate the gains from eliminating excess supplies and from the introduction of new goods have a much wider applicability; they may be used to obtain and synthesize several welfare results from the literature.
