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...

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...

The mapping of frequency rates of events is an important tool for guiding public policy. Nevertheless, this problem has not received adequate attention by most researchers. In many studies, the used ratios have serious problems when the geographic units have a small population at risk and when...
