Abstract

This paper investigates the effects of the SNAP Online Purchasing Pilot expansion (SNAP OPP) on SNAP households' online grocery shopping behaviors and the healthfulness of their food‐at‐home purchases. We explore quasi‐experimental estimates of the impact of online purchasing by leveraging a unique natural experiment: the staggered introduction of the SNAP OPP across US states. The analysis combines data on household food‐at‐home purchases around the time of the policy expansion with a dynamic difference‐in‐differences empirical strategy. The results indicate that the SNAP OPP increased the frequency of online grocery shopping, associated spending, and the healthfulness of food‐at‐home purchases among SNAP households.
