We use a sales database of farmers market vendors in the Washington, D.C., area to estimate how first half 2020 sales were impacted by the COVID-19 outbreak. We use 2019 data as a counterfactual for sales that would have occurred in 2020 in the absence of COVID-19. For neighborhood weekend markets that were able to remain open during the pandemic, the change in 2020 average sales between the winter and spring is between 75% and 79% lower than in 2019. Other farmers markets, particularly weekday markets in business districts, experienced delayed openings or were closed for the entire year.

US farmers market managers must be strategic in deciding which vendors sell at their markets. They would benefit from understanding how market characteristics impact vendor sales, although the few studies that have explored this topic have found inconclusive results. We use a unique panel database of sales at 13 farmers markets to estimate how vendors' sales are influenced by the characteristics of their farmers market. We find that average sales at weekend farmers markets becomes increasingly large as farmers markets increase in size. At weekday markets, average sales increase as small markets add vendors but eventually decline as markets become larger. These results could occur if weekend markets attract shoppers from increasingly greater distances as they become larger, while average sales eventually decline as weekday markets increase in size due to vendor competition. Produce vendors experience higher average sales at weekend markets than weekday markets and experience a relatively small increase in sales as market size increases. Vendors of hot prepared foods experience higher sales at weekday markets [EconLit Citations: Q10, Q12, Q13].
