From the Executive Summary: " The Coronavirus Aid, Relief, and Economic Security (CARES) Act created a $600 federal supplement to state unemployment insurance payments, which will expire on July 31st, but as states begin to reopen, this supplement will create a disincentive for people to return to work.  Nationally 63 percent of workers currently make more on unemployment with the federal supplement than they would working, but even if the federal supplement is reduced to $100 a week, 25 percent of the U.S. workforce could still make more on unemployment than returning to work.  Due to variations between states, changing the amount of the federal supplement will affect the incentives for some workers more than others, indicating that a uniform federal policy might not be the best approach."
