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....

The elasticity of taxable income (ETI) is often interpreted as a sufficient statistic to assess the welfare costs of taxation. Building on the conceptual framework of Chetty (2009), we show that this assertion does no longer hold for tax systems with deduction possibilities if (i) deductions...

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 2004, the German pension authority started to send out annual letters providing detailed and comprehensible information about the pension system...

In this paper, we investigate the impact of the COVID-19 pandemic on German household income using a micro-level approach. We combine a microsimulation model with labour market transition techniques to simulate the COVID-19 shock on the German labour market. We find the consequences of the...

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...

The highly dynamic nature of the COVID-19 crisis poses an unprecedented challenge to policy makers around the world to take appropriate income-stabilizing countermeasures. To properly design such policy measures, it is important to quantify their effects in real-time. However, data on the...

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...
