Several recent studies show that the elasticity of taxable income (ETI) is not a sufficient statistic for the welfare costs of taxation due to factors such as taxbase shifting. This paper provides an additional argument demonstrating the non-sufficiency of the ETI, namely tax deductions....

Using a series of controlled laboratory experiments involving decisions to intervene in others’ choice opportunities; we find that groups grant more autonomy to others than individuals. This finding is robust across two decision contexts, one involving individual decision-making (Internality)...

This paper provides evidence of efficient taxation of groups with heterogeneous levels of "tax morale". We set up an optimal income tax model where high tax morale implies a high subjective cost of evading taxes. The model predicts that "nice guys finish last": groups with higher tax morale will...

We present the first randomized survey experiment in the context of tax compliance to assess the role of social norms and reciprocity for intrinsic tax morale. We find that participants in a social-norm treatment have lower tax morale relative to a control group while participants in a...

Do groups and individuals behave differently in dictator games with varying deservingness of the recipient? Does the involvement in group-decision making affect the decisions of group members in subsequent individual decisions? We address these questions using a controlled dictator-game...

How can retirement savings be increased? We explore a unique policy change in the context of the German pension system to study this question. As of 2005 (with a phase-in period between 2002-04), the German pension administration started to send out annual letters providing detailed and...

Much economic analysis derives policy recommendations based on social welfare criteria intended to model the preferences of a policy maker. Yet, little is known about policy maker's normative views in a way amenable to this use. In a behavioral experiment, we elicit German legislators' social...

Whether observed differences in redistributive policies across countries are the result of differences in social preferences or efficiency constraints is an important question that paves the debate about the optimality of welfare regimes. To shed new light on this question, we estimate labor...

The distributional consequences of the recent economic crisis are still broadly unknown. While it is possible to speculate which groups are likely to be hardest-hit, detailed distributional studies are still largely backward-looking due to a lack of real-time microdata. This paper studies the...

Because of endogeneity problems very few studies have been able to identify the incidence of corporate taxes on wages. We circumvent these problems by using an 11-year panel of data on 11,441 German municipalities' tax rates, 8 percent of which change each year, linked to administrative matched...
