This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of across-income heterogeneity in preferences, inheritances, income-shifting capabilities, and other sources. We study unrestricted tax systems on income and...

This paper is concerned with cross-dependencies between endogenous market structure and tax policy. We extend the Mirrlees (1971) model of income taxation with a monopolistic competition framework with general additively separable consumer preferences. We show that price and variety distortions...

Theoretical discussion on compensating mechanisms involving the Pareto criterion that address inequality rather than absolute welfare is non-existent in trade literature. In a simple HOS model we consider tax-transfer policies that keep the pre-trade degree of inequality unchanged between...

This paper aims to provide a perspective on the ideal tax system using insights from optimal-tax theory supplemented with empirical evidence. These insights are applied to actual policy questions regarding the progressiveness of the labor income tax, in-work tax credits, the design of the...

Recently, a voluminous literature estimating the taxable income elasticity has emerged as an important field in empirical public economics. However, to a large extent it is still unknown how the hourly wage rate, an important component of taxable income, reacts to changes in marginal tax rates....

Social values shape policy outcomes. We examine the role of postmaterialism, a widely used concept in the social sciences, for the mix of capital and labour taxation chosen by a society. Following political scientist Inglehart, we define the degree of postmaterialism as the relative importance...

According to conventional wisdom internationally mobile capital should not be taxed or should be taxed at a lower rate than labour. An important underlying assumption behind this view is that there are no market imperfections, in particular that labour markets clear competitively. At least for...

We present an applied general equilibrium modelling approach to analyse employment and unemployment effects of labour tax cuts in an economy where wages are determined through firm-union bargaining at the sectoral level. In such a labour market regime, simulations for Germany show that labour...
