We present a general-equilibrium behavioural microsimulation model designed to assess long-run macroeconomic, fiscal and social consequences of reforms to the tax and transfer system. The behaviour of labour supply is assessed along both the extensive and intensive margins, by merging the...

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 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...

The interplay of a differentiated indirect tax structure and the variation in expenditure patterns across households, leads to a possibly unequal distribution of indirect tax liabilities across the population. This paper uses the ninth round of the RLMS survey to assess the distributional...

This paper evaluates the welfare effects of the 1986 Tax Reform Act (TRA86). In thirty years since its introduction, several studies have analysed the effects of TRA86. However, preference heterogeneity and non-market dimensions of welfare have not been taken into account. We propose an...

Due to limited access to foreign savings after the 2008 crisis, transition economies are forced to rely more on domestic savings in financing their growth. In that respect, it is often argued that the government should use tax policy to encourage domestic savings. Since the personal income tax...

This paper provides an assessment of the poverty and social impact of replacing Ethiopia`s sales tax with a value-added tax (VAT). The results indicate that this reform has not had a major adverse effect on the poorest 40 percent of the population. The VAT is progressive in its incidence, and...

We show that an insight from taxation theory allows identification of both the supply and demand elasticities with only one instrument. Ramsey (1928) and subsequent models of taxation assume that a tax levied on the demand side only affects demand through the price after taxation....
