The vector autoregressive and structural vector autoregressive (VAR/SVAR) models are the cornerstone of the contemporaneous empirical macroeconomic research, in particular for measuring the impact of fiscal policy shocks. They may be employed as atheoretical models, as well as a mean to support...

So far, there are very few papers concerning the problems of non causality and non-fundamentalness in fiscal studies. This is even truer for Brazil. Non causality and non fundamentalness are econometric problems that are specially relevant in fiscal studies, as they are relate to fiscal...

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 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 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 shows new econometric estimates for the Brazilian function of aggregate imports. Besides the basic relation, which includes income and relative price and identifies a demand equation (canonic model), we explore the pronounced co-movements between total imports, household consumption...

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...
