Geography Matters: International Trade Patterns and the Indirect Land Use Effects of Biofuels
研究了国际贸易模式如何影响全球粗粮生产对价格变化的反应，发现地理因素在生物燃料政策导致的土地利用变化中起关键作用。
This article investigates the relationship between international trade patterns and the global distribution of coarse grain production responses to market developments in the United States. Our null hypothesis is that world markets are fully integrated, rendering the geographic persistence of bilateral trade flows irrelevant in the global production response to a change in U.S. prices. The alternative hypothesis allows price transmission to vary along with the intensity of competition among countries in specific markets. Using data from 1975 to 2002, we reject the null hypothesis. Our work has direct implications for the analysis of the global land use impacts of biofuel mandates.
