Many researchers and policymakers have made strong arguments for broadening the taxes on wealth and its returns. Although the theoretical literature on (optimal) wealth taxation is growing, there exists a large void in empirical research. This paper addresses this void by analysing the...

We investigate bunching at personal tax thresholds over a 40-year period. At kinks, where the marginal tax rate rises, we find bunching among company owner-managers and the self-employed, but not those with only employment income. Notches, where the average rate rises, provide compelling...

Establishing an equitable and efficient tax system is essential for reducing poverty, combating inequality, and fostering sustainable economic growth. Rwanda's government has recognized this and implemented significant changes to the personal income tax schedule for 2023 and 2024 as part of...

We estimate the responses of gross labor earnings with respect to marginal and average net-of-tax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and the payroll-tax schedules that affect individuals who earn less than twice the minimum wage. Our...

We estimate the responses of gross labor income with respect to marginal and average net-of-tax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and payroll-tax schedules affecting individuals who earn less than twice the minimum wage. Our estimate for...

When possible income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship based on microeconometric research have not...

According to the standard principal-agent model, the optimal composition of pay should balance the provision of incentives with the individual demand for insurance. Do income taxes alter this balance? We show that the relative share of PRP on total pay is reduced by higher average taxes, and is...

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we develop and estimate a structural microeconometric model, in which a high-school graduate decides to...

In order to calculate the burden of a comprehensive and progressive income tax falling on a certain income source, an apportionment scheme for the entire tax burden has to be chosen. This raises the question of how to deal with losses, which is relevant for Germany in view of the heavy losses...

Microsimulation based on income tax statistics may be useful in tax reform discussions. Unfortunately, access to appropriate data is still rather restricted and expensive for ad-hoc analyses, or individual data is often even not available at all. In this paper we take Germany and its data...
