This paper offers a first empirical investigation of how labor taxation (income and payroll taxes) affects individuals' well-being. For identification, we exploit exogenous variation in tax rules over time and across demographic groups using 26 years of German panel data. We find that the tax...

We analyze to which extent social inequality aversion differs across nations when controlling for actual country differences in labor supply responses. Towards this aim, we estimate labor supply elasticities at both extensive and intensive margins for 17 EU countries and the US. Using the same...

We investigate how potential tax-driven migrations modify the Mirrlees income tax schedule when two countries play Nash. The social objective is the maximin and preferences are quasilinear in income. Individuals differ both in skills and migration costs, which are continuously distributed. We...

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to...

We derive a sufficient statistics optimal tax formula in a general model that incorporates unemployment and endogenous wages, to study the shape of the tax and transfer system at the bottom of the distribution. The sufficient statistics are the macro employment response to taxation and the micro...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework with endogenous (voluntary) nonparticipation and (involuntary) unemployment. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global...

We analyze the optimal nonlinear income tax schedule when taxpayers earn multiple incomes and differ along many unobserved dimensions. We derive the necessary conditions for the government s optimum using both a tax perturbation and a mechanism design approach, and show that both methods produce...
