Identifying Buyer Market Areas and the Impact of Buyer Concentration in Feeder Cattle Markets Using Mapping and Spatial Statistics
通过地图和空间统计方法，分析美国四个主要肉牛饲养区买家的市场区域，发现买家采购区域大、形状不规则且重叠，在买家集中地区存在寡头买方行为，影响价格。
Abstract The size and shape of market areas for buyers from four major cattle feeding areas are determined by mapping data from the nation's largest video auction. Spatial statistics are also examined to determine their ability to identify market areas for feeder cattle. Mapping shows that procurement areas for feeder cattle buyers are large, irregularly shaped, and overlap substantially. A new statistic was developed to determine primary market areas. Feeder cattle buyers behave as oligopsonists in counties where most buyers are from one feeding area, and prices are higher for feeder cattle in counties where two or more market areas overlap.
