Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...

This paper explores the long-run impacts of tax policy in a two-country model of endogenous growth with variable labor supply. We focus on international spillover effects of tax reforms under alternative trade structures. It is shown that if the instantaneous utility function of the...

A standard result in the optimal taxation literature is that, when agents differ in market ability and the government aims at redistributing from high- to low-skilled agents by means of an optimal nonlinear labor income tax and a set of commodity taxes, an optimally designed commodity tax...

We study optimal income and commodity tax policy with credit-constrained low-income households. Workers are assumed to receive an even ow of income during the tax year, but make tax payments or receive transfers at the end of the year. They use their disposable income to purchase multiple...

The purpose of this paper is threefold. First, we survey the way in which the tax burden on labour has been proxied for in recent multi-country macro-economic studies. Second, we critically evaluate these proxies. Finally, we examine to what extent the conclusions of some studies change if some...

Measuring effective tax rates using tax revenue data is attractive, given that revenues collected capture the net effect of tax provisions and taxpayer behaviour that are difficult to model. Yet reliance on aggregate tax and income data requires restrictive assumptions and significantly limits...

We document contemporaneous differences in the aggregate labor supply of married couples across 17 European countries and the US. Based on a model of joint household decision making, we quantify the contribution of international differences in non-linear labor income taxes and consumption taxes...

The Dutch pension system is internationally top-ranked as a well-designed three-pillar system. Moreover, almost all forms of pension benefits are expenditure taxed in line with the European Commission's recommendations. Consequently, the Dutch pension policy approach could be regarded as a...

This study provides evidence for the US that the secular decline in the labor share is not only explained by technical change or globalization, but also by the dynamics of factor taxation, automation capital (robots), and population growth. First, we empirically find indications of...
