We document the time-series of employment rates and hours worked per employed by married couples in the US and seven European countries (Belgium, France, Germany, Italy, the Netherlands, Portugal, and the UK) from the early 1980s through 2016. Relying on a model of joint household labor supply...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

The 2017 US tax legislation - widely referred to as the Tax Cut and Jobs Act (TCJA) - fundamentally transformed the US system of international taxation. It ostensibly ended worldwide taxation but introduced, for instance, a new tax on "Global Intangible Low-Taxed Income" (GILTI). This paper...

We provide quasi-experimental evidence on the income tax-induced migration of foreign high-income households living in Switzerland by exploiting the differential tax treatment of UK and US households. While the two groups are similar in terms of non-tax sorting preferences, US households are...

The gains in life expectancy are expected to double the dependency ratio and increase population by 10% in Switzerland until 2050. To quantify the effects on pensions, taxes and social contributions, we use an overlapping generations model with five margins of labor supply: labor market...

With varying aptitudes in different occupations, individuals typically maximize income by specializing in one occupation which promises the highest income. Due to numerous labor market imperfections and uncertainties, the choice of best occupation is accomplished with only partial success. We...

The dual income tax provides the self-employed entrepreneur with huge incentives to participate in tax minimizing income shifting to have more of his income taxed as capital income. The Norwegian split model is designed to remove these incentives, but it contains loopholes. The present paper...

The Dutch Parliament has passed legislation for a new income tax that abolishes the current tax on personal capital income and substitutes it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital...

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...

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...
