Spatial Pricing Patterns in the United States
用多元线性回归和Chow检验，发现竞争对手的位置和竞争强度是决定美国企业定价模式的关键因素，并识别出各州定价差异，地理价格歧视是最普遍的定价手法。
This paper is an empirical extension of spatial price theory with results being established by selected statistical approaches, namely multiple linear regression and Chow's test. The locational pattern of competitors as well as varying intensities of competition at different spatial market points are found to play dominant roles in determining the pricing patterns of American firms. Differences in the price practices of firms of different states are identified, and price discrimination over geographic space is found to be the most prevalent pricing technique.
