Dr. Katie Harris-Lagoudakis's article "The New Normal: Grocery Shopping Behavior Changes Before and After the COVID-19 Vaccine" has been accepted at Applied Economic Perspectives and Policy.

The article uses transaction data from a large grocery store retailer to describe changes in grocery shopping behavior associated with the progression of the COVID-19 pandemic before and after the vaccines were developed. The authors find that in general, households increased their spending and decreased their number of transactions early in the pandemic. They also find changes in a store’s spending and transactions, along with the healthfulness of these purchases, vary significantly with the racial composition of a store’s market and these differential changes persisted after vaccines were available.
