This paper presents new econometric specifications for the Brazilian exports in the period 1995-2009 using data from the Quarterly Accounts and allowing for nonlinearities. In the cointegrating vector, there is evidence of a level shift, but the elasticities have not changed significantly. The...

This article presents various econometric specifications - most notably Markov- Switching models - for the fiscal reaction function of the Brazilian consolidated public sector after the 1994 ?Real Plan?. The results reported here strongly suggest that a major structural break has happened in the...

This study suggests an alternative approach, nested in exogeneity tests, to verify Ricardian Equivalence. The intuitive appeal and the sophisticated statistical method are the advantage of this new procedure. Furthermore, two others contributions are made: a) an explanation to the failure of...

This paper estimates the Brazilian NAILO (Nonaccelerating Inflation Level of Output), obtains (Bayesian) probability bands for the Nailo and for its growth rate, and investigates the relationship between deviations of output with respect to the Nailo and the acceleration of inflation. As...

The technological and institutional environment influences the way of doing research and the relationships between its participants. Intellectual property is a strategic issue to build the institutional framework of the new technological regime and therefore the dynamics of innovation in...

This article discusses the dynamics of both the size and the composition of the Brazilian aggregate tax burden (BATB) in the 1995-2007 period and presents several (linear and non-linear) econometric specifications for this last variable. Our main conclusion - based both on the analysis of the...
