In 2021, the U.S. Congress temporarily expanded the Earned Income Tax Credit for workers without a qualifying child (childless EITC), to help counteract the impact of the COVID-19 pandemic on lower-wage working adults. This expansion roughly tripled the maximum benefits for qualifying filers and...

We study the persistent effects of temporary changes in U.S. federal corporate and personal income tax rates using a narrative identification approach. A corporate income tax cut leads to a sustained increase in GDP and productivity, with peak effects between five and eight years. R&D spending...

How do different income taxation systems affect household decisions and welfare? We answer this question by first documenting the strong labor supply disincentives for secondary earners of the U.S. tax system and by using variations from the Bush Tax Cuts to assess their effects on...

California has the highest Earned Income Tax (EITC) supplement to the federal EITC, with an 85% supplement rate. However, we find that despite the apparent generosity of the California EITC, there is no employment effect on less-skilled single mothers, in sharp contrast to the evidence of...
