The work was carried out in the district of Fonseca, municipality of Alvinópolis, state of Minas Gerais, in the Rio Doce microregion, between 20°09' 35" S and 43°17' 55" W. The research area was divided, using the concept of sample homogeneity, into urban and rural sectors, and data on daily firewood consumption were obtained by weighing, admitting a sampling error of 10%, with a total of 107 households surveyed. It was found that firewood collection in the district is a very intensive practice and constitutes an activity in which all able-bodied family members participate. In the urban sector, it was observed that 15% of consumers acquired firewood through direct marketing, with an estimated average price of approximately US$0.25 per adult bundle (approximate weight of 30 kg for dry firewood), while in the rural sector, there are no points of sale. Specific firewood consumption in the Fonseca district was estimated at 22.19 kg/household/day, with 25.53 kg/household/day in the rural sector and 18.63 kg/household/day in the urban sector. Total consumption was estimated at 16,477 st/year, equivalent to 1,957.97 TOE (tons of oil equivalent), which is very significant in terms of impacts on the conservation of local forest biomass. Total firewood consumption was distributed as follows: 9,907 st/year for the rural sector and 6,570 st/year for the urban sector. In view of the estimated consumption results, it was inferred that there is a need to develop small-scale community forestry programs under specific management plans for the sustainable production of firewood in these communities.

Because of no legal binding of those revenues exist there is a recommendation that they be used in order to ensure the well being of the population. The aim of the study was to analyze whether these rents from natural resources contributed to the development in the municipalities baianos in the period 2005-2010. No statistic significant relationship between royalties and IFDM was found. On the other hand, a negative and significant relationship was found between CFEM and IFDM, corroborating the literature of the resource curse.

Additionally, it is estimated an income equation for the State. The inequality and poverty indicators are compared with the ones of the other Northeastern States, Northeast Region and Brazil. It is used the data of the PNAD, referred to the year 2002 and accomplished by IBGE. The results indicate a pattern for national inequality, however poverty indicators show a relatively worse situation for the Northeast Region. The regressions for the income equation emphasize significant differences of income among several categories.

Autor(es): Andrade, Cláudia Sá Malbouisson; Eskereski, Stefanie; Silva, Vinícius Felipe da Abstract: The discussion about important determinants of educational quality is quite extensive and controversial in economics of education literature, especially when discussing the impact of school resources. The class size is one of the central factors in this debate because is under direct control of public policies. The objective of this study is to investigate the impact of class size on learning in mathematics of students in the 5th grade of elementary school of public schools in the city of Salvador in 2011. For this, we use the method of instrumental variables to control for the endogeneity in the definition of class size. The results show that, controlling for other factors, there is an optimal size of the number of students in each class, and that beyond this number the performance impact becomes negative in municipal schools in the city of Salvador.
