Although discrete hours choice models have become the workhorse in labor supply analyses. Yet, they are often criticized for being a black box due to their numerous underlying modeling assumptions, with respect to, e.g., the functional form, unobserved error components or several exogeneity...

Due to strong evidence indicating that tax morale affects actual tax-paying behavior, finding the determinants of tax morale could help both to understand and to fight tax evasion. In this paper we analyze the effect of progressive taxation on individual tax morale using a cross-country...

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:...

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the...

Previous estimates of inequality of opportunity (IOp) are lower bounds because of the unobservability of the full set of endowed characteristics beyond the sphere of individual responsibility. Knowing the true size of unfair IOp, however, is important for the acceptance of (some) inequality and...

The economic crisis has given rise to significant challenges to the welfare state. Given that welfare expenses account for a large proportion of all state spending in the member countries of the European Union, reducing government spending means cutting welfare measures. Yet social protection,...

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...

It is widely believed that globalization affects the extent of employment and wage responses to economic shocks. To provide evidence for this, we analyze the effect of firms’ exporting behavior on the elasticity of labor demand. Using rich, German administrative linked employer-employee panel...
