This paper examines the optimal direction of marginal income tax reform in the context of New Zealand, which recently reduced its top marginal income tax rate to one of the lowest in the OECD. A behavioural microsimulation model is used, in which social welfare functions are defined in terms of...

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...

This paper presents annual Swedish time series data on the top marginal tax wedge and marginal tax wedges on labor for a low, average and high income earner for the period 1862 to 2010. We identify four distinct periods separated by major tax reforms. The tax system can be depicted as...

The purpose of the paper is to provide a discussion of the various approaches for accounting for labour supply responses in microsimulation models. The paper focuses attention on two methodologies for modelling labour supply: the discrete choice model and the random utility - random...

During the last decade, several EU countries have tried to tackle unemployment and low activity rates through extensive tax cuts. In an effort to encourage the taking up of work - especially amongst the less productive workers - policymakers have shown increasing interest in targeted tax and...

In the period 2001-2004 two major reforms followed in Belgium: a personal income tax reform (2001) and a reform of social security contributions for low skilled employees (2004). Using a discrete hours labor supply model, this paper assesses the impact of these reforms on aggregate labor supply...

Policy makers are generally interested in both the anti-poverty impact and the efficiency of reforms. To connect these two dimensions, I measure the poverty gap change per unit of net revenue that tax-benefit reforms produce. To isolate the impact of reforms and account for labour supply...

This paper focuses on the study of the effects on social welfare generated by the scheme of joint taxation of the Spanish Personal Income Tax (PIT), whose peculiarity linked to its condition of optionality, allows the minimization of households´ tax bill. Different scenarios are simulated using...
