In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite...

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the "harmony" of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out efficient bargaining). The model...

This study examines optimal taxation in a unionized economy in which households save capital. The main findings are as follows. Judd’s (1985) and Chamley’s (1986) classical results of zero taxation on capital income holds. This is true independently of workers’ savings behaviour or the...

In this paper fiscal policy is examined for an open economy characterised by unemployment due to efficiency wages. We allow for capital and firm mobility in a model where the government chooses the level of wage, source-based capital and profit taxation. The taxing choices of governments are...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework with endogenous (voluntary) nonparticipation and (involuntary) unemployment. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global...

The Mirrlees Review of the UK tax system, together with its companion volume of research papers, can be expected to influence future discussions of tax reform. Indeed, this can already be recognised in the Henry Review. As far as income taxation is concerned, the most substantive recommendation...

Economists traditionally tackle normative problems by computing optimal policy, i.e. the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I...

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...

Gender Based Taxation (GBT) satisfies Ramsey’s optimal criterion by taxing less the more elastic labor supply of (married) women. This holds when different elasticities between men and women are taken as exogenous and primitive. But in this paper we also explore differences in gender...
