Do minimum wages reduce in-work-poverty and wage inequality? Or can alternative policies do better? We evaluate theses issues for the exemplary case of Germany that suffers from high unemployment among low-skilled workers and rising wage dispersion at the bottom of the wage distribution. We...

I analyze whether wage policies - like minimum wages and wage subsidies - can add value to an optimal non-linear earnings tax scheme in a perfectly competitive labour market. Jobs in the labour market differ along two margins: intensity (labour effort) and duration (labour hours). Three key...

This paper examines the effect of the Earned Income Tax Credit (EITC) and welfare programs on the labor supply of single mothers. The EITC consists of an earning subsidy program in the form of marginal tax credits to the working poor. The presence of different marginal tax rates at the various...

This paper examines whether income inequality is affected by the structural progressivity of national income tax systems. Using detailed personal income tax schedules for a large panel of countries, we develop and estimate comprehensive, time-varying measures of structural progressivity of...

This paper analyzes the effect of changes in structural progressivity of national income tax systems on observed and actual income inequality. Using several unique measures of progressivity over the 1981-2005 period for a large panel of countries, we find that progressivity reduces inequality in...

This paper examines how human capital based approaches explain the distribution of earnings. It assesses traditional, quasi-experimental, and new micro-based structural models, the latter of which gets at population heterogeneity by estimating individual-specific earnings function parameters....

How much employment can be generated by decreasing payroll taxes? We examine this question by exploring the staggered rollout of a large payroll tax reform in Brazil. Using administrative matched employer-employee data, we find an increase of 5 percent on employment due to both firm growth and...

We show that a minimum wage introduced in the presence of asymmetric information about worker productivities will lead to lower unemployment levels than predicted by the standard labour market model with heterogeneous labour and symmetric information.
