The interaction of supply and demand side is not explicitly modeled, which might lead to biased estimates of potential labor market outcomes. This paper proposes a straightforward method to...

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...

This paper studies the tax treatment of couples. We develop two different approaches. One is tailored to the analysis of tax systems that stick to the principle that the tax base for couples is the sum of their incomes. One is tailored to the analysis of reforms toward individual taxation. We...

We analyze how the combined effect of automatic stabilizers and discretionary changes in taxbenefit systems have affected the cushioning of income shocks in the Euro zone and the EU-27 in the period 2007-2014. We propose a new summary measure of the combined effect of automatic stabilizers and...
