Tax Policy and Business Entry, with Dustin Swonder

Abstract: This paper measures the effects of state corporate and personal income tax reforms on business entry using an event study research design. We focus on reforms that do not coincide with federal tax changes, are preceded and followed by stable tax policy, and substantially change tax burdens. Corporate tax reforms cause meaningful changes in business entry: we measure a 5-year elasticity of 2.7 with respect to the net-of-tax rate. This is driven by large effects of tax cuts. Corporate tax cuts also reduce the predicted growth potential of entrants. We do not find strong evidence of cross-border spillovers, and find no evidence that personal income tax reforms affect business entry.
