There exists a wide variety of tax treatments of pensions across the world. And the reasons for such a range of regimes are not clear. This note reviews the general principles of pension taxes and analyses the theoretical foundations of why pension incomes ought to be taxed specifically. To do...

We study the labor supply implications of the Old-Age Pension Act (OPA) of 1908, which, for the first time, provided pensions to older people in the UK. Using recently released census data covering the entire population, we exploit variation at the newly created age-based eligibility threshold....

We study the interactions between capital income tax and social security privatization in the context of rising longevity. In an economy with idiosyncratic income shocks, redistributive defined benefit social security provides some insurance against income uncertainty. This insurance comes at...

Given its significance in practice, piecewise linear taxation has received relatively littleattention in the literature. This paper offers a simple and transparent analysis of its maincharacteristics. We fully characterize optimal tax parameters for the cases in which budgetsets are convex and...

Does joint taxation disadvantage women? To answer that question, this paper begins byreviewing unitary and bargaining models of intrafamily allocation, and then discusses thedeterminants of "bargaining power" in a world without taxes...

When a deficit occurs in the funding of collective goods, it is usually covered by raising theamount of taxes or by rationing the supply of the goods. This article compares the efficiencyof these institutions. We report the results of a 2x2 experiment based on a game in the firststage of which...

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in...

The purpose of this paper is to present an exercise where we identify optimal income tax rules under the constraint of fixed tax revenue. To this end, we estimate a microeconomic model with 78 parameters that capture heterogeneity in consumption-leisure preferences for singles and couples as...

We use a behavioural microsimulation model embedded in a numerical optimization procedure in order to identify optimal (social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic income and a tax defined by a 4th degree polynomial....

We study the role and structure of commodity taxes when consumption and labor supplies are determined through a bargaining procedure between spouses, and where an optimal income tax is also available. We focus on the question whether there should be differences in tax treatment between "female"...
