Microsimulation models are increasingly used to calibrate macro models for tax policy analysis. Yet, their potential remains underexploited, especially in order to represent the non-linearity of the tax and social benefit system and interactions between capital and labour incomes which play a...

Given a settled reduction in the present level of tax revenue, and by exploring a very large combinatorial space of tax structures, in this paper we employ a genetic algorithm in order to determine the optimal structure of a personal income tax that allows the maximization of the redistributive...
