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...

The optimal design of low income support is examined using a structural labour supply model. The approach incorporates unobserved heterogeneity, fixed costs of work, childcare costs and the detailed non-convexities of the tax and transfer system. The analysis considers purely Pareto improving...

This paper is the first to provide evidence of efficient taxation of groups with heterogeneous levels of 'tax morale'. We set up an optimal income tax model where high tax morale implies a high subjective cost of evading taxes. The model predicts that 'nice guys finish last': groups with higher...

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...

We consider a case where some of the parents have higher ability to raise children than others. First-best policy gives both types of parents the same level of utility. If parental actions are not fully observable, however, the policy maker has to take into account the incentive-compatibility...
