Abstract:We analyse the effect of taxes and benefits on income distribution of six Latin American countries: Argentina, Bolivia, Colombia, Ecuador, Uruguay, and Venezuela. Our analysis makes use of tax-benefit microsimulation models based on harmonized household representative survey data and developed within the structure of EUROMOD. The analysis focuses on the relative importance of tax-benefit instruments across countries and on the effect of taxes and benefits on poverty and inequality. The selected countries represent a wide range of cases in terms of the redistributive role of the tax-benefit system with Uruguay providing a large degree of redistribution, whereas the Bolivian system has a very modest role. We further exploit the advantages of our models and perform a simulation exercise whereby the most progressive income tax system of our set of countries is applied to the rest and assess its effect on inequality and revenue. Our paper represents the first study making use of microsimulation techniques to assess the redistributive role of tax-benefit systems in the region in a comparable manner, and highlights the advantages offered by microsimulation models to evaluate the effect of policy reforms aiming to improve social protection in the region. Acknowledgements:The results presented here are based on three projects: (i) LATINMOD a project sponsored by CELAG, funded by BANDES and with the collaboration of EUROMOD. (ii) ECUAMOD v1.0. ECUAMOD is developed, maintained and managed by UNU-WIDER in collaboration with the EUROMOD team at ISER (University of Essex), SASPRI (Southern African Social Policy Research Institute) and local partners in selected developing countries (Ethiopia, Ghana, Mozambique, Tanzania, Zambia, Ecuador and Viet Nam) in the scope of the SOUTHMOD project. The local partner for ECUAMOD is Instituto de Altos Estudios Nacionales (IAEN). (iii) COLMOD, project developed independently by David Rodriguez. We are indebted to the many people who have contributed to the development of LATINMOD, SOUTHMOD and ECUAMOD. We are grateful to Pia Rattenhuber and participants to the SOUTHMOD workshop in Helsinki for useful comments on earlier versions of the paper. The results and their interpretation presented in this publication are solely the authors' responsibility.
