International Productivity Differences: A Nested Test of Increasing Returns to Scale Models

这个项目的目的是确定国际生产率差异和比例模型的收益增加如何解释国际贸易的模式。该项目的第一阶段涉及编制世界贸易环境的详细数据库，其中将载有1963-1992年期间75个国家54个工业的双边贸易流量、工业生产、资源资源和投入产出关系的数据。这是一项雄心勃勃的数据收集工作，但完全可以实施，并将向公众提供。该项目的第二阶段将确定最适合理解生产力和人力资本在美国经济成功中的作用的贸易模式。没有这些信息，就不可能设计出明智的公共政策，无论是积极的还是不干预的。通过提供这些信息，这项研究的结果应该有助于政策制定者在美国和全球范围内建立更强大的经济。

The purpose of this project is to determine how international productivity differences and increasing returns to scale models can explain patterns of international trade. The first phase of the project involves developing a detailed database of the world trading environment that would contain data on bilateral trade flows, production by industry, resource endowments, and input-output relationships for 54 industries in 75 countries over the period 1963-1992. This is an ambitious data gathering exercise, but is fully implementable and will be made publicly available. The second phase of the project will identify models of trade that are most appropriate for the purpose of understanding the role of productivity and human capital for U.S. economic success. Without such information it is impossible to design informed public policy, be it pro-active or noninterventionist. By providing this information, the results of this research should aid policy-makers in building a stronger economy, both within the United States and globally.
