Spatial Distribution of Retail Sales

摘要: We examine the distribution of sales for a retail chain in Houston market using spatial gravity model. Unlike previous empirical studies, our approach models dependencies among both consumers and retailers. The results show that forms dependence exert statistically economically significant impacts on estimates parameters models. Contrary to suggestions (Gautschi, D. A. (1981). “Specification Patronage Models Retail Center Choice,” Journal Marketing Research 18, 162–174.) as well (Eppli, M. J., J. Shilling. (1996). “How Critical Is Good Location Regional Shopping Center?” Real Estate 12, 459–468.), importance distance parameter may be greatly understated. Thus, ignoring lead overestimation deterministic extent trade areas, underestimate good locations.
