This paper proposes a set of new methods to estimate inequality of opportunity based on conditional inference regression trees. It illustrates how these methods represent a substantial improvement over existing empirical approaches to measure inequality of opportunity. First, the new methods...

Abstract General Equilibrium Models have become a powerful tool of policy analysis in recent years. We provide an overview of the theoretical concept of Applied General Equilibrium Framework by reviewing the standard theory of producer and consumer behaviour. Moreover we discuss several popular...

European countries have the world's most redistributive tax and transfer systems. Although they have been well equipped to deal with vertical inequality -- that is, fostering redistribution from the rich to the poor -- less is known about their performance in dealing with horizontal inequality,...

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,...
