We provide an explanation for the growth of intermediated local foods based on the observation that consumers prefer to buy local foods as part of a shopping basket that includes both local and non-local items. We test our hypothesis using data from a natural experiment conducted by Relay Foods, an online retailer based in the U.S. state of Virginia, and a multi-variate logit model of shopping-basket demand. We find significant complementarities among items in a sample shopping basket that are not reflected in estimates from a discrete-choice model of category demand. Estimates of a structural pricing-and-local-content model reveal important incentives for retailers to offer local foods as part of a broader selection of grocery items. 收起
