LOCATION, PLANTING DECISIONS, AND THE MARKETING OF QUALITY-DIFFERENTIATED AGRICULTURAL COMMODITIES
建立模型分析地理分散的农户在收获后营销年度内的均衡种植与营销决策，关注两种质量差异化农产品（生物技术与非生物技术），并考察营销环境对空间种植模式的影响。
In a marketing environment, the demand conditions, the costs of shipping and storing grain varieties, the interest rate on farm loans, and the distribution of cropland in the area are important determinants of growers' planting decisions. In this article, I focus on a market for two quality-differentiated agricultural commodities: one produced with the use of biotechnology and the other, without. I develop a model for analyzing the equilibrium planting and marketing decisions made by geographically dispersed producers during the marketing year following harvest. I identify the types of marketing environments leading to a greater concentration of equilibrium acreage planted to a particular grain variety near the market and investigate the effects of the marketing environment on the spatial patterns of equilibrium land allocation among grain varieties.
