How effective was pandemic aid?

We use an instrumental-variables estimator reliant on variation in congressional representation to analyze the macroeconomic effects of federal aid to state and local governments across all four major pieces of COVID-19 response legislation. Through December 2022, we estimate that the federal government allocated $603,000 for each state or local government job-year preserved. Our baseline confidence interval allows us to rule out estimates smaller than $220,400. Our estimates of effects on aggregate income and output are centered on zero and imply modest if any spillover effects onto the broader economy.

That is from a new paper by Jeffrey Clemens, Philip Hoxie, and Stan Veuger.  Via the excellent Kevin Lewis.
