This article aims to estimate the dynamic factor model for prediction tax receipts in Brazil using monthly data for the period 2001-2013. The factorial model allows to reduce the dimensionality of the high number of taxes taking into account the information contained in the existing...

This article evaluates the main effects for the Brazilian economy from the creation of a free trade zone among the BRICS economies. A welfare analysis suggests the Chinese economy to be the closest - in comparison to the remaining BRICS - to the definition of a natural trade partner for Brazil....

This article presents a linear econometric model with variable coefficients for the analysis of the quarterly dynamics of the Brazilian gross tax burden in the 1995-2008 years.The choice of this particular model was motivated by the constant changes made in the Brazilian tax system during these...

The aim of this article is to estimate a Bayesian factorial dynamic model for the analysis and forecasting of the Brazilian tax burden (BTB) using monthly data from 1996 to 2007. Twenty taxes are responsible for about 80% of the BTB, each of which with a distinct seasonal pattern The factorial...

This article analyses the evolution and the composition of gross aggregate tax burden and government transfers in Brazil and their relationships with equity and income distribution for the period 1995-2008. Along this period, gross aggregate tax burden grew considerably motivated by the...
