Eficiência técnica da agropecuária nas microrregiões brasileiras e seus determinantes

This study intends to measure the scores of technical efficiency of agriculture and cattle raising activity in the 556 Brazilian microregions and to check their determinants. In order to achieve these goals, the data envelopment analysis models (DEA) and the quantile regression were used. The data were obtained from the Agricultural and Cattle raising Census (2006) published by the Brazilian Geography and Statistics Institute - IBGE. The results of the DEA model indicated low technical efficiency in production. So far as the quantile regression model is concerned, one can observe that technical assistance, fertilization, granted credit and family labor constitute relevant factors in accounting for the differences of technical efficiency of Brazilian microregions in all amounts estimated.

Eficiência técnica da Polícia Militar em Minas Gerais

This study sought to calculate an efficiency index in crime fighting that would allow comparison between Minas Gerais State military police units. The efficiency index were calculated by Data Envelopment Analysis and the results indicated a large discrepancy between the municipalities analyzed and possible public security policy could try to raise efficiency levels in the worst municipalities using the most efficient ones as benchmarks. Furthermore, a Tobit model was estimated to test the relevance of the social and economic environmental exercised in achieving the efficiency index. The results showed that the set of variables used explained only 10% of the variability of the index calculated.

DESEMPENHO COMPETITIVO DA AGRICULTURA FAMILIAR EM SANTA CATARINA

The aim of this work is to identify the determinant factors of family farming competitiveness in municipalities of Santa Catarina (SC) through the Index of Competitive Performance of Family Farming (IDAF) and multiple regression analysis and also to check for significant differences in competitiveness of family farming between mesoregions that State through parametric tests of Levene and of t Student for unpaired data. A sample of 183 municipalities of Santa Catarina has been considered out of the total of 293 municipalities in this state. The data has been collected from Agricultural Census (2006), which is publicized in the website of Brazilian Institute of Geography and Statistics (IBGE). The results indicate that family farming in municipalities of Santa Catarina is, in general, low and intermediate level of competitiveness. The regression analysis confirmed positive relationship between the annual income and the factors of competitiveness analyzed. In addition, it was found that there are significant differences in the average competitiveness of the family farming between mesoregion of Vale do Itajai and mesoregions of Florianopolis and Serrana. Therefore, it is concluded that there is great heterogeneity in municipalities of Santa Catarina in relation to the competitive performance of family farming.
