The public debate over the merits of the federal expansion to state unemployment insurance (UI) programs began even before the Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed in March 2020. The controversy over whether expanded and extended UI benefits discourage some recipients from returning to work flares up each time the temporary programs expire and Congress debates whether and how they should be renewed. Following the widespread availability of effective vaccines against COVID-19 beginning in April 2021, the debate shifted to how and when to appropriately end expanded UI benefits. In May, 26 states unexpectedly announced that they would suspend participation in the federal expansion to UI benefits by late June or early July—more than two months before the federally scheduled end date. This unexpected change offers a unique opportunity to estimate the effect of UI changes on workers’ return to employment.
