We model a two sector economy with unionized labor markets and competitive product markets, where workers and unions care about their relative wages, and show that the presence of a relative wage concern could help generation a positive relationship between tax progressivity and wage pressure.

We study the empirical relationship between labor taxation and pretax wages in Italy. We find that higher tax progressivity increases pretax wages. To explain this result, we introduce in an informal way a relative wage effect and argue that the combination of this effect with the labor supply...

This paper proposes measures to quantify the effective level and the effective progressivity of taxation in a fiscally decentralized country taking income sorting into account. Using data on the universe of Swiss taxpayers, we find that rich households effectively face significantly lower...

Recent years have witnessed the growth of mass-marketed tax avoidance schemes aimed at the middle (not top) of the income distribution, with significant implications for tax revenue. We examine the consequences, for the structure of income tax, and for tax authority anti-avoidance efforts, of...

We study the incidence and the optimal design of nonlinear income taxes in a Mirrleesian economy with a continuum of endogenous wages. We characterize analytically the incidence of any tax reform by showing that one can mathematically formalize this problem as an integral equation. For a CES...

We present new empirical evidence for the US economy that inflation reduces the inequality of the earnings distribution. The main mechanism emphasized in this paper is the tax income bracket effect. Governments only adjust the nominal income tax brackets slowly to a rise in prices, typically...

This paper examines the allocative implications of progressive income taxation when individuals care about their relative income. It shows that tax progressivity might improve efficiency, and the more so in egalitarian economies. Introducing a progressive income tax can yield a Pareto...

The goal of this paper is to study the effects of introducing income redistribution at the municipal level, with the adoption of local tax progressivity. In particular, we analyse whether this complex fiscal tool modifies the incentives of local politicians to be strategic leading to higher tax...

This study aims at contributing to the ongoing debates on the bracket creep, whether Germany needs an integration of inflation indexation into its personal income tax system in order to re-duce distortions of tax liabilities and additional tax burdens. On the other hand, Germany has continuously...

This paper investigates the distributional and efficiency consequences of an environmental tax reform, when the revenue from the green tax is recycled by varying labor tax rates. We build a general equilibrium model with imperfect heterogeneous labor markets, pollution consumption externalities,...
