There is clear evidence that fairness plays a role in redistribution. Individuals want to compensate others for their misfortune, while they allow them to enjoy the fruits of their effort. Such fairness considerations have been introduced in political economy and optimal income tax models with a...

Many countries provide extra resources to schools serving disadvantaged pupils. We exploit a discontinuity in the assignment of such personnel subsidies in Flanders to estimate the impact on cognitive outcomes via a regression discontinuity (RD) design. Because bias can be substantial in RD...

School accountability schemes require measures of school performance, and these measures are in practice often based on pupil test scores. It is well-known that insufficiently correcting these test scores for pupil characteristics may provide incentives for inefficient pupil selection. We show...

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...

This paper describes IZAΨMOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZAΨMOD consists of three components:...

Deutschland wird im europäischen Vergleich häufig ein überdurchschnittlich progressives Steuersystem attestiert. Die einzigartige, mehrstufige Progressionsformel der Einkommensteuer trägt ohne Zweifel zu dieser Sichtweise bei. Um ein umfassendes Bild der Progressivität eines Gesamtsystems...

Die Steuervorschläge der Parteien stellen einen wesentlichen Teil ihrer Wahlprogramme für die Bundestagswahl 2013 dar. Sie werden in der Öffentlichkeit kontrovers diskutiert, da davon ausgegangen wird, dass sie einen erheblichen Einfluss auf die Wahlentscheidung haben wer-den. Daher stellt...

Firms' labor demand responses to wage changes are of key interest in empirical research and policy analysis. However, despite extensive research, estimates of labor demand elasticities remain subject to considerable heterogeneity. In this paper, we conduct a comprehensive meta-regression...

Previous reviews of static labor supply estimations concentrate mainly on the evidence from the 1980s and 1990s, Anglo-Saxon countries and early generations of labor supply modeling. This paper provides a fresh characterization of steady-state labor supply elasticities for Western Europe and the...

There is still considerable dispute about the magnitude of labor supply elasticities. While differences in micro and macro estimates are recently attributed to frictions and adjustment costs, we show that relatively low labor supply elasticities derived from microeconometric models can also be...
