Abstract

Gaigné and Larue (American Journal of Agricultural Economics 98:1432–1449) examined the welfare implications of quality regulations within an international trade context, employing a general-equilibrium framework. Their study uses a CES (Constant Elasticity of Substitution) model and finds that stricter public standards might improve welfare. However, this conclusion was actually derived from a partial-equilibrium analysis. This note conducts a thorough general-equilibrium analysis and demonstrates that their anticipated outcome does not hold within their CES framework.

评《全球经济中的质量标准、产业结构与福利》

gaign和Larue （American Journal of Agricultural Economics 98:1432-1449）采用一般均衡框架，研究了国际贸易背景下质量法规对福利的影响。他们的研究使用了恒定替代弹性（CES）模型，发现更严格的公共标准可能会改善福利。然而，这个结论实际上是由部分平衡分析得出的。本报告进行了全面的一般均衡分析，并证明他们的预期结果不符合其CES框架。

期刊介绍： The American Journal of Agricultural Economics provides a forum for creative and scholarly work on the economics of agriculture and food, natural resources and the environment, and rural and community development throughout the world. Papers should relate to one of these areas, should have a problem orientation, and should demonstrate originality and innovation in analysis, methods, or application. Analyses of problems pertinent to research, extension, and teaching are equally encouraged, as is interdisciplinary research with a significant economic component. Review articles that offer a comprehensive and insightful survey of a relevant subject, consistent with the scope of the Journal as discussed above, will also be considered. All articles published, regardless of their nature, will be held to the same set of scholarly standards.
