Suinocultura no Estado de Goiás: aplicação de um modelo de localização

The main purpose of this research work was to analyse the most efficient spatial distribution of pig production units in the state of Goias. The model developed required a mixed integer programming structure. The factors considered in the model were: the grain transportation cost (corn and soybeans) from the source to the production unit, the cost of transporting the animals from the production unit to slaughterhouses and the carcass transportation cost from the slaughterhouse to retailers. The consumption market was spatialy defined as comprising the state of Goias, the Distrito Federal and the counties of Sao Paulo, Rio de Janeiro and Belo Horizonte. Moreover, it was determined the supplies of corn and soybeans for each microregion in the state of Goias and the national per capita pork consumption. Three scenarios, showing different per capita consumption levels, were considered. One of these is the current per capita consumption level and the two other were determined according to sector perspectives.

Decomposição estrutural da variação do emprego no Brasil, 1991-2003

The aim of this article was to analyze the variation of employment in the Brazilian economy in the period between 1991 and 2003 through the decomposition of structural change in employment intensity effect, technology effect, structure of final demand effect and change in final demand effect. It was also estimated the rates of structural change in employment, production and value added. The results showed the displacement of jobs in industrial and agricultural sectors for trade and services with increase in the total number of people employed in 7.30 million, with the effects of varying intensity and showed that the final demand the highest values.

O impacto do Programa Minha Casa, Minha Vida na economia brasileira: uma análise de insumo-produto

O objetivo do presente artigo foi analisar o impacto do Programa Habitacional Minha Casa, Minha Vida na economia brasileira mediante a dinamizacao do setor da construcao civil, utilizando a matriz de insumo-produto de 2008 para estimacao dos geradores e multiplicadores de producao, renda, emprego e impostos. Os resultados mostraram que o setor da construcao civil apresentou ligacoes para tras e para frente abaixo da media dos setores da economia. No entanto, considerando o valor de R

Economic growth x environment: forecasts for the Brazilian economy and its 5 macro regions, 2002 to 2012

125,7 bilhoes previstos para investimento no periodo em analise, constatou-se que havera crescimento significativo na renda paga aos trabalhadores, serao criados cerca de 7 milhoes de empregos diretos e indiretos, havera aumento na producao de cerca de 6% do PIB em valores de 2010, e pelo menos 16% do valor dos subsidios dados nos contratos de financiamento do PMCMV voltarao aos cofres publicos.

Environmental and Regional Impacts in Growth Scenarios for the Brazilian Economy

Using the MIBRA model, an Applied Interregional General Equilibrium Model, constructed for the Brazilian economy and its five macro regions (North, Northeast, Central West, Southeast, an South), this papers tries to identify which would be the impact of the economic growth in the Brazilian economy an in its macro regions, from 2002 to 2012, on environmental variables, i.e., organic and inorganic materials, particulates, sulfurates, water, energy, CO2, and the Amazon rain forest. Concerning the economic growth rates, two scenarios are constructed, one pessimist and other optimistic, and the impact of both scenarios on the environmental variables are then measured. Some major environmental concerns are raised for each one of the Brazilian macro regions: a) for the North region, represented mainly by the Amazon rain forest, it is taken into the consideration the trade off between the area used by agricultural activities with the area used by the rain forest; b) for the Northeast region, the main concern is the restriction on water use; c) for the Central West region, it is taken into consideration the expansion of the agriculture frontier; d) for the Southeast and South regions, the more industrialized regions, pollutants are a problem

A estrutura teórica do modelo inter-regional para a economia brasileira - MIBRA

This study simulates environmental effects with the inter-regional general equilibrium model Mibra assuming economic growth rates in a pessimist scenario of 2.3% a.a. and an optimist scenario of 4.4% a.a., both for the period 2002-2012. Using pollution intensity coefficients associated to production activities, environmental effects were estimated for the whole country as well as for the regions North, Central, Northeast, Southeast and South. Results indicate that reducing concentration growth in the axes Southeast-South may improve environmental efficiency of the whole economy with lower ratios of industrial pollution and water and energy use levels per unit of output produced.
