An antitrust authority deters collusion using fines and a leniency program. It chooses the probability of an investigation. Firms pick the degree of collusion: The more they collude, the higher are profits, but so is the probability of detection. Firms thus trade-off higher profits against...

In Zeiten, in denen die öffentliche Abgabenlast deutlich zunimmt, wächst die Neigung zur Steuerhinterziehung. Einmal begangen, scheint Steuerhinterziehung vielfach irreversibel, weil bei deren Unterlassen Entdeckung droht. Um Steuerpflichtigen die Rückkehr zur Steuerehrlichkeit zu...

Tax authorities worldwide are implementing voluntary disclosure schemes to recover tax on offshore investments. Such schemes are typically designed retrospectively following the bulk acquisition of information on offshore holdings, such as the recent Paradise and Panama papers. They offer an...

This paper analyzes the effect of lifting primary school fees on educational attainment in Uganda. After the abolishment of school fees in 1997, the enrollment rate more than doubled. Two decades later, however, we know little about the effect of the policy on educational attainment. With recent...

We provide evidence about voters' response to crime control policies. We exploit a natural experiment arising from the Italian 2006 collective pardon releasing about one third of the prison population. The pardon created idiosyncratic incentives to recidivate across released individuals and...

Since the 1990ies several countries abolished the wealth tax, but surprisingly few scholars investigated the effects empirically. Motivated by the theoretical literature, this study estimates the effect of the abolition of the net wealth tax in Germany in 1997 on the household saving rate. The...

This study uses an original state-level data set to investigate whether press coverage on trials for tax evasion by celebrities affects the likelihood that other tax payers participate in Germany's tax amnesty program. To identify the causal effect, we use exogenous variation in the reporting,...

Do general amnesty programs lead to reductions in the crime rate among immigrants? We answer this question by exploiting both cross-sectional and time variation in the number of immigrants legalized generated by the enactment of repeated amnesty programs between 1990 and 2005 in Italy. We...

Millions of people enter (or remain in) countries without permission as they flee violence, war, or economic hardship. Regularization policies that offer residence and work rights have multiple and multi-layered effects on the economy and society, but they always directly affect the labor market...

What is the effect of opening the labor market to foreign workers on the success of firms? We address this question by analyzing how firms in Switzerland were affected by the introduction of the free movement of persons with the European Union (EU) countries. This immigration reform granted all...

We develop a model to understand the trade-offs faced by an elected representative in supporting an amnesty when a restrictive immigration policy is in place. We show that an amnesty is more desirable the more restricted are the occupational opportunities of undocumented immigrants and the less...

This paper estimates the effect of the abolition of user charges for children’s outpatient care (30 CZK/1.2 EUR) in 2009 on the demand for ambulatory doctor visits in the Czech Republic. Because the reform applied only to children, we can employ the difference-in-differences approach, where...
