The paper tried to contribute to the theory of the location of the bank services. At first, there was strong evidence showing that the bank location not only depended on economical factors. The developed model and the results found in the spatial econometrics analysis demonstrated that there is...

We study the interaction between dispersed and sticky information by assuming that firms receive private noisy signals about the state in an otherwise standard model of price setting with sticky-information. We show that there exists a unique equilibrium of the incomplete information game...

In this paper we consider a nonlinear model based on neural networks as well as linear models to forecast the daily volatility of the S&P 500 and FTSE 100 indexes. As a proxy for daily volatility, we consider a consistent and unbiased estimator of the integrated volatility that is computed from...

In this paper, we introduce a linearity test for fuzzy rule-based models in the framework of time series modeling. To do so, we explore a family of statistical models, the regime switching autoregressive models, and the relations that link them to the fuzzy rule-based models. From these...

The main aim of this paper is to construct a complete analysis of exports and the mains transportation modals in the Brazilian economy. In order to implement this analysis we will use na inter-sectoral hybrid input-output matrix for the Brazilian economy. We will incorporate the modals of...

This article traces evidences of the evolution of some school efficiency indicators in Brazil, namely: Attendance Rate, Gross Schooling Rate, Net Schooling Rate; Age-Grade distortion rate. Our analysis permeates nearly three decades of educational policies in Brazil, by the computation of the...

Este trabalho apresenta um cenário macroeconômico com detalhamento das repercussões regionais, a partir da articulação dos resultados de um modelo de consistência macroeconômica com um modelo de equilíbrio geral computável (EGC) inter-regional. O foco são as repercussões do cenário...

The present study explores and describes, in detail, an application of the Grade of Membership (GoM) method, widely used in demographic studies. It presents an exercise to data used in a previous study (Assis and coleagues, 2008), which relates to neonatal deaths in a public hospital in Belo...

The aim of this article is to realize a comparative methodological exercise of two APC estimators: the conventional restrict estimator obtained by the generalized linear models (MLGR) and the so-called intrinsec estimator (EI). Both instruments are contrasted by means of the parameter estimates...

The aim of this paper is to analyze the effects of economic downturn with the crisis of 2009 on the Brazilian economy, especially on activity sectors and states. To get a consistent picture of these impacts, which takes into account economic macroeconomic indicators and sectoral data (exports...
