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 study estimates demand elasticities for staple foods in Brazil taking into account the differences in demand behaviour across urban and rural areas. We analyze microdata from 2002/2003 household expenditure survey (POF), conducted by IBGE. The methodology adopted in demand estimation is...

Applying econometric models on panel data, we analyzed the possible relation between the increase in broadband Internet access density in Brazil and the GDP and GDP per capita growth. Broadband access densities, GDP, GDP per capita and the population education level data were disaggregated at...

This paper presents a discussion on several econometric models for estimating parametric models in the presence of spatial dependence with cross-section data. Initially, we cover models for spatial dependence with spatial lags of the response variable and spatial lags of the residues, and...
