This paper presented some economic insights that would bring a tax reduction for the Brazilian economy. Initially, we started with the hypothesis that Ricardian equivalence does not hold in the economy and that a tax reform aimed at eliminating existing distortions in the Brazilian economy would provide gains in equity as well as welfare gains for agents. At first, the focus of the work focused on contextualizing the characteristics of the Brazilian economy based on dynamic Laffer curve trying to describe the limits of government action. Using quarterly data for the period 1997 to 2009, found the evidence supported the hypothesis that the Brazilian economy is subject to a dynamic Laffer curve, i.e., there is room for a tax reduction to improve the interrelationship between macroeconomic real economic variables in order to expand the pace of economic growth. Secondly, the objective was to verify the presence of Ricardian equivalence and its impact on the Brazilian economy. Using quarterly data from 1997 to 2009, the results showed that the Brazilian economy is not subject to the Ricardian equivalence hypothesis. Furthermore, we proceeded to superexogeneity test the function parameters consumption estimated to test the hypothesis Ricardian equivalence and found that they can be considered superexogenous, i.e., results can be considered safe for inferring about public policy through the estimated equation. These results, taken together, demonstrate that a reduction in taxation in the country can benefit agents as aggregate consumption increase. Given the aggregate consumption as a measure of well-being then in that sense, the national welfare would be increased. Furthermore, this increase would generate positive effects on income and on the rest of macroeconomic variables.
