This paper presents a new methodology for hierarchical spatial clustering of contiguous polygons, based on a geographic coordinate system. The proposed algorithm is built upon a modification of traditional hierarchical clustering algorithm, commonly used in the multivariate analysis literature....

This paper studies a methodology for hierarchical spatial clustering of contiguous and homogeneous polygons, based on a set of binary variables. The proposed algorithm is built upon a modification of traditional agglomerative hierarchical clustering algorithm, commonly used in the multivariate...

This paper developed and applied the Stochastic Frontier Geographically Weighted (SFGW) to access the tax efficiency of the Brazilian states. The estimated coefficients obtained by this method were close to those from the traditional Stochastic Frontier estimation allowing, however, the...

In this paper, by using cross-section regression analysis, we studied the economic and human development factors affecting the diffusion of the broadband internet access at the level of municipalities in Brazil. As economic development indicators we used the GDP per capita, GDP and how it is...

Using demand and supply simultaneous equations, including endogenous variables, it was analyzed the possible economic impact on the GDP and GDP per capita, resulted of the increase in the broadband internet access diffusion in Brazil. Broadband penetration, GDP, GDP per capita and population...

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...

In this paper, we present some models to analyze the impacts of surface transportation logistic costs on importers and exporters decisions on which ports to choose for foreign trade operations. We employed a technique based on fractional split distributions, in which the dependent variable...
