Tax progressivity is central in public and political debates when questions of vertical equity are raised. Applied, structural research demands a simple way to capture it. A power function approximation delivers one parameter that captures the residual income elasticity - a summary measure of progressivity. This approximation is accurate, tractable, and interpretable, and hence immensely popular. The ...

Wealth transfer taxes are important instruments to counter increasing wealth inequality. Yet, inter-generational business transfers, whose distribution is particularly concentrated at the top, are inherently difficult to tax. This is due to preferential tax treatments in many countries and sophisticated tax avoidance strategies by business owners. We analyze how business transfers react to...

According to theory, "sin taxes" are welfare improving if consumers with low self-control respond at least as much to the tax as consumers with high self-control. We investigate empirically if demand response to soft drink and fat tax variations in Denmark depends on consumers' self-control. We use a unique home-scan panel that includes a survey measure of self-control. When taxes increase, consumers ...

Policymakers widely use tax-based incentives to spur investment and stimulate economic growth. Tax policy has been at the center of emergency measures during the Covid-19 pandemic, and it is now as countries face a significant deterioration in public finances. Yet, empirical tax research is still in disagreement on how taxes affect business investment. We investigate the effect of local business...

We decompose earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks, we formulate a life-cycle model of consumption and labor supply. For estimation, we use data on married American men from the Panel Study of Income Dynamics. Permanent wage shocks explain ...

This study examines how inheritance and gift tax systems in combination with gendered parental transfer behavior strengthen gender wealth inequalities. Gender differences in transfers can be reproduced if men benefit differently than women from tax exemptions. This might happen when men and women receive different types of assets where only some are tax exempted. To investigate gendered parental...
