Over the last decades, Latin American countries have experienced a noticeable decrease in income inequality. While this trend is mainly associated with a decline in wage inequality, progressive reforms of the tax-benefit systems of the region may have played a role. While redistributive systems in Latin America are still in their infancy, they are constantly expanding and do so at different pace in the region. To investigate this point in a comparative way, the present study exploits newly developed tax-benefit microsimulation models for Ecuador and Colombia. These two neighboring countries show contrasted situations in terms of income distribution and we characterize the extent to which this difference is explained by different tax-benefit systems. The comparative nature of our microsimulation models allows us to swap tax-benefit systems between countries to produce counterfactual simulations whereby the system of a country is applied to the population of the other. In this way, we can decompose the total country difference in income distribution to extract the role of different tax-benefit policies. We confirm that the Ecuadorean system is more redistributive and quantify the difference: if the Ecuadorean system was applied to the Colombian population, the Gini coefficient would be reduced by 1.7 points in Colombia. Headcount poverty would decrease by around 10% and the intensity of poverty by up to 14.7%. This analysis contributes to the recent literature on the redistributive role of taxbenefit systems in Latin America and highlights the role of microsimulation techniques to show how countries in the region can learn from each other in order to improve social protection and reduce income inequality.

To do so, we use representative microdata from Ecuador and Colombia, together with detailed tax-benefit models, and simulate transitions to formal employment for all workers observed in informality in the data, with informality defined as non-affiliation to social security. Our results point to strikingly high formalization costs in the two countries, with on average 52.8 and 78.5 per cent of workers' additional earnings taxed away due to social security payments in Ecuador and Colombia, respectively. Costs are particularly high for self-employed informal workers at the bottom of the earnings distribution. The results are mainly driven by the requirement that workers contribute to social security at least on the basis of the minimum wage in both countries.

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.

El presente trabajo tiene por objeto analizar cómo se distribuyen las distintas fuentes de ingresos de los Estados y Territorios de Australia, a fin de evaluar la contribución de cada una de ellas a la desigualdad final resultante y valorar si el sistema de financiación es progresivo o regresivo y por qué. Para ello, la metodología aplicada es la descomposición natural de los índices de concentración y la descomposición directa del índice de Suits, resultando que la distribución de los recursos financieros es altamente igualitaria y algo progresiva, a lo cual contribuye fundamentalmente las transferencias. Ahora bien dicha progresividad en la distribución de los recursos totales se convierte en regresividad entre los Estados y Territorios con mayor nivel de producción per cápita. Esto se debe a que las transferencias benefician especialmente a los Estados y Territorios con menor tamaño poblacional.
