The Competitive Structure of U.S. Agricultural Exports
通过分析美国农产品出口定价对汇率变动的反应，检验出口市场的竞争结构，发现棉花、玉米和大豆的定价不支持价格歧视，而小麦贸易中两大进口国可能利用市场力量压低价格。
Abstract The competitive structure of U.S. agricultural exports is examined using a model of exporter behavior based on pricing decisions across destination markets. Market power is revealed in the adjustment patterns of export prices in response to exchange rate movements. The results reject the hypothesis that the export pricing decisions by U.S. firms are consistent with price discrimination across destination markets for cotton, corn, and soybeans. The strongest evidence against the competitive market structure is obtained for international trade in wheat, where results indicate that the two largest importers (Soviet Union and PRC) may exert market power to obtain lower prices.
