Dual income tax systems have become increasingly popular; yet, relatively little is known about the consequences of implementing such tax systems. This paper uses a representative panel of taxpayers from the 1993 Finnish tax reform to measure how overall taxable income and the relative shares of...

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 reduce distortions of tax liabilities and additional tax burdens. On the other hand, Germany has continuously...

The semi-dual income tax typically combines a progressive tax schedule for labour and pension income with low and often flat and differentiated nominal tax rates on some forms of capital income. This paper discusses the rationale for the adoption of semi-dual income tax in the taxation of...

Fertility has long been declining in industrialised countries and the existence of public pension systems is considered as one of the causes. This paper is the first to provide detailed evidence based on historical data on the mechanism by which a public pension system depresses fertility. Our...

We examine how allowing individuals to emigrate to pay lower taxes abroad changes the optimal non-linear income tax scheme in a Mirrleesian economy. An individual emigrates if his domestic utility is less than his utility abroad net of migration costs, utilities and costs both depending on...

This paper analyzes the welfare effects of the Italian social security system in an economy with uncertainty on wages, financial market returns and life expectancy. The introduction of a pension system reproducing the Italian statutory scheme turns out to decrease ex-ante individual welfare,...

This paper explores the optimal income tax treatment of couples. Each couple is modelled as a single agent supplying labor along two dimensions: primary-earner and secondary-earner labor supply. We consider fully general nonlinear income tax schedules which creates a multi-dimensional screening...

Given its significance in practice, the piecewise linear tax system seems to have received disproportionately little attention in the literature on optimal income taxation. This paper offers a simple and transparent analysis of its main characteristics
