In this work our aim is to estimate the biomass density over Amazônia Legal, extrapolating the punctual data from the project Radam-Brasil. Under the hypothesis that the density, or one of it's components, varies smoothly in space, we worked with two different model specifications: Armae...

The neigbohood effect was used to analyze two problems of farm activity in Brazil. The first estimate a measure of total factor productivity for 550 homogeneous micro region, that is defined as a latent variable with the spatial trend propriety. The second analyze the occupation process in the...
