Do Fast-Food Chains Price Discriminate on the Race and Income Characteristics of an Area?
检验了快餐店在不同种族和收入特征的地区是否收取不同价格，基于新泽西和宾夕法尼亚400多家餐厅的数据，发现黑人比例每增加50%，餐价约上涨5%。
Abstract This article reports tests for differences in prices charged by fast-food restaurants that serve markets with customers of widely divergent incomes and ethnic backgrounds. The data contain detailed prices on items sold at over 400 Burger King, Wendy's, KFC, and Roy Rogers restaurants in New Jersey and Pennsylvania locations. I find significant differences in price based on the race and income characteristics of a zip-code region. When income and cost differences are taken into account, meal prices rise approximately 5% for a 50% rise in the black population.
