价格影响食品购买决策，特别是在低收入社区，因为这些社区的食品零售商（包括超市）的渠道有限。本研究的目的是研究小型城市食品商店和最近的超市之间主食定价的差异，以及定价差异是否因小型商店和大型零售商之间的距离而变化。 2014 年，在明尼阿波利斯/圣路易斯的 140 家小型商店（街角商店、加油站、一元店和药店）走访期间测量了 15 种主食的价格。明尼苏达州保罗和他们最近的超市。使用控制商店类型的混合模型来估计以下之间的平均价格差异：(a) 较小的商店和超市； (b) 孤立的小型商店（距离最近的超市 >1 英里）和非孤立的小型商店； (c) 将较小的商店隔离在美国农业部确定的食品沙漠内部和外部。平均而言，除白面包外的所有商品在小型商店中都比超市贵 10-54% (p < 0.001)。与非独立商店相比，大多数商品的价格通常没有显着差异。在孤立的商店中，食品沙漠内部与外部没有价格差异。我们得出的结论是，与最近的超市相比，无论距离远近，较小的食品店大多数主食的价格都较高。需要更多的研究来检验不同零售场所的主食价格。
Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger retailers. In 2014, prices were measured for 15 staple foods during store visits in 140 smaller stores (corner stores, gas-marts, dollar stores, and pharmacies) in Minneapolis/St. Paul, MN and their closest supermarket. Mixed models controlling for store type were used to estimate the average price differential between: (a) smaller stores and supermarkets; (b) isolated smaller stores (>1 mile to closest supermarket) and non-isolated smaller stores; and (c) isolated smaller stores inside versus outside USDA-identified food deserts. On average, all items except white bread were 10–54% more expensive in smaller stores than in supermarkets (p < 0.001). Prices were generally not significantly different in isolated stores compared with non-isolated stores for most items. Among isolated stores, there were no price differences inside versus outside food deserts. We conclude that smaller food stores have higher prices for most staple foods compared to their closest supermarket, regardless of proximity. More research is needed to examine staple food prices in different retail spaces.
