Clicks as a Healthy Alternative to Bricks: How Online Grocery Shopping Reduces Vice Purchases
研究发现，相比实体店，在线杂货购物中消费者会购买更少的不健康食品，因为线上展示降低了产品的生动性，从而减弱了即时满足的欲望。
Although consumers are concerned about their health, obesity statistics suggest that contextual factors often lead them to choose unhealthy alternatives (i.e., vices) rather than healthy ones (i.e., virtues). Noting the increasing prevalence of online grocery shopping, the authors focus on shopping channels as one such contextual factor and investigate how food choices made online differ from food choices made in a traditional brick-and-mortar store. A database study and three lab experiments demonstrate that consumers choose relatively fewer vices in the online shopping environment. Moreover, this shopping channel effect arises because online channels present products symbolically, whereas offline stores present them physically. A symbolic presentation mode decreases the products' vividness, which in turn diminishes consumers' desire to seek instant gratification and ultimately leads them to purchase fewer vices. These findings highlight several unexplored differences between online and offline shopping, with important implications for consumers, public policy makers, and retailers.
