This paper examines whether income transparency - the public release of citizens' income information - affects support for redistribution. We leverage a quasi-experiment in Finland, where every year on the so-called tax day, the authorities release income information on Finland's top earners to...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

This paper provides new empirical insights on the elasticity of taxable income to the net-oftax rate. Using a panel of German income tax return data, we followed taxpayers from 2001 to 2006 to analyze the effects of the German tax reforms of 2004 and 2005. Implementing a dynamic model as...

This paper provides new empirical insights on the elasticity of taxable income for Germany. Using a rich panel of German income tax return data, the tax reforms of 2004 and 2005 are exploited implementing a new dynamic income model. Showing and discussing potential estimation problems of the...

Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint...

Generous income support programs as provided by European welfare states have often been blamed to hamper employment. This paper investigates the importance of incentives inherent in the tax-benefit system for the individual decision to take up work. Using German microdata over the period...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...

We analyze the compliance costs of individual taxpyers resulting from the German income tax. using survey data that has been raised between December 2008 and April 2009, we find evidence for a considerably higher cost burden of self-employed taxpaxers. Taxable income and the demand for external...

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...

What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax...
