A Political-Economic Model of U.S. Bilateral Trade
构建了一个包含经济和政治变量的引力模型，分析影响美国与66个贸易伙伴双边贸易的因素，发现市场力量之外的政治因素同样重要。
A bstract-Interrelationships between economics and politics have long been recognized by scholars in the field of international relations. This paper attempts to identify and quantify the factors aflecting bilateral trade flows between the United States and other countries by developing a gravity type model. The model includes economic and political variables and is tested using data for sixty-six U.S. trading partners. Results indicate that pure economic variables which reflect market forces are not the only factors affecting U.S. bilateral trade. Semi-cconomic and international political factors are also important.
