We study the economic behaviors and demographics of Amazon Mechanical Turk (MTurk) workers during the COVID-19 pandemic, and compare it to a pre-pandemic MTurker sample, a student sample, and a representative sample of the United States. We find that MTurkers during the pandemic behave differently than previous MTurkers in many contexts, even after accounting for changes in demographic composition. These MTurkers behave more similarly to a pre-pandemic representative sample than a student sample. Additionally, we revisit gender differences in preferences and document fewer and smaller differences in many contexts. These results help contextualize online research conducted during the pandemic.
