中文摘要
共享经济最引人注目的发展之一,是按需服务不受约束的迅猛扩张。在本文中,我们考察此类平台的一个子集——在线外卖平台(如 Grubhub、UberEats、DoorDash)——如何影响美国家庭的备餐与就餐行为。为此,我们利用 Grubhub 平台于 2005 年至 2019 年间分批进入美国各县的事实,采用双重差分方法。结果表明,此类外卖服务的可得性导致在家备餐时间显著减少,而外出就餐并未发生相应变化。在需求更大以及餐馆数量更多的地区,这一效应有所增强;而在经济可行性较低的情形下(即失业率较高的地区以及子女较多的家庭),该效应减弱。我们还考察了 Grubhub 服务的可得性与随后人口身体质量指数 (BMI) 变化之间的关联。本文讨论了其对研究、消费者、平台以及公共卫生的启示。本文由 Anindya Ghose(信息系统)接受。补充材料:在线附录和数据文件可在 https://doi.org/10.1287/mnsc.2023.02636 获取。
Abstract
One of the most notable developments of the sharing economy is the unfettered proliferation of on-demand services. In this work, we examine how a subset of such platforms, online food delivery (e.g., Grubhub, UberEats, DoorDash), has affected the meal preparation and dining behaviors of American households. To do so, we exploit the phased entry of the platform Grubhub into U.S. counties from 2005 to 2019 using a difference-in-difference approach. Results indicate that the availability of such delivery services leads to a significant reduction in time spent preparing meals within the home, with no concomitant change in dining out. This effect is intensified in areas subject to greater demand and in areas with a greater number of restaurants but abates when less economically feasible (i.e., in areas with higher unemployment and households with more children). We also explore the association of Grubhub availability with subsequent changes in population body mass index. Implications for research, consumers, platforms, and public health are discussed.
