Tax Policy and Firm Entry and Exit Dynamics: Evidence from OECD Countries

In this paper we study the effects of reforms to corporate and personal income taxation on the rate of firm entry and exit using industry data for 19 OECD countries from 1998 to 2005. Using a difference-in-differences approach to correct for endogeneity bias we find that increases in corporate taxation affect entry but not exit. The effects of personal taxation depend upon the marginal tax rate that is altered. Increases in marginal tax rates applied at low income levels negatively affect entry and positively affect exit, whereas marginal tax reforms at higher income levels have the opposite effect.
