Neighborhood Differences in Retail Food Stores: Income Versus Race and Age of Population
研究发现，在黑人及老年人集中的社区，零售食品店的价格更高、质量与清洁度更低，且品牌和规格选择更少。
Retail food stores may vary from one location to another in terms of the price and quality of products offered for sale, selection of products and sizes available, and cleanliness of the stores themselves. The effects of socioeconomic characteristics of the neighborhoods in which stores are located on a set of store and product characteristics are estimated, holding constant factors that affect costs of the stores. The major finding is that consumers in neighborhoods with high concentrations of black and elderly people face higher prices, lower levels of quality and cleanliness, and less variety of prices, brands, and sizes.
