Amazônia legal: análise de convergência da renda municipal com base em um modelo threshold
(2009-06) DINIZ, Marcelo Bentes; OLIVEIRA JÚNIOR, José Nilo de; FERREIRA, Roberto Tatiwa; PAIXÃO, Alex Sandro da
This paper is an analysis of the process of convergence of income between the municipalities of the Legal Amazonia in the period of 1980 to 2004, trying to identify the existence of clubs of convergence using a model threshold. Results indicated for the formation of six clubs of convergence, among them shows a process of convergence between the clubs extremes. In general, human capital proved to be significant in explaining the process of growth of the groups of municipalities richer. The results also indicated that the physical capital was significantly negative for explaining the process of economic growth of most clubs of convergence, demonstrating in this way, a negative role for public investment undertaken in the districts of the region.

Análise da área desmatada municipal na Amazônia brasileira no período 2000-2004: uma abordagem com modelos não lineares
(2010-09) OLIVEIRA JÚNIOR, José Nilo de; DINIZ, Marcelo Bentes; FERREIRA, Roberto Tatiwa; CASTELAR, Luiz Ivan de Melo; DINIZ, Márcia Jucá Teixeira
There is a great amount of asymmetry in the distribution of deforestation in the Brazilian Legal Amazon, particularly in the states of Mato Grosso, Pará and Rondônia, what it would be, in principle, associate with certain common characteristics of their productive activities such as cattle, timber cutting and, more recently, the expansion in the production of grains. However, it can be inquired if municipalities with similar economic characteristics can be grouped as clubs with respect to deforestation. The goal of this article was to test the club convergence hypothesis of deforested areas in the cities of the Legal Amazon in the period of 2000 to 2004. In order to reach the objectives considered, a threshold model based in Hansen (2000) was used. The empirical results corroborate the hypothesis, with respect to formation of four clubs of convergence.

Arranjo produtivo do artesanato na Região Metropolitana de Belém: uma caracterização empírica
(2007-12) DINIZ, Marcelo Bentes; DINIZ, Márcia Jucá Teixeira
This article presents the handicraft industry in the Metropolitan Region of Belém, treating it as a productive arrangement. Primary data obtained from field work carried out in 2005 by the authors, was combined with secondary data from research carried out by SEBRAE in 2002. The most significant empirical aspects regarding the functioning of this arrangement are constituted by five main elements: the company and entrepreneurs, dynamics of innovation, learning, knowledge and cooperation and, finally, the most significant aspects of its management. The questionnaire developed by Redesist (IE-UFRJ) regarded the activities connected with handicrafts and was given to directly to the “producers”, in accordance with a representative sample. Among the results obtained, the most significant were the relations of family work, a lack of professionalism, a low degree of cooperation, despite innovations with respect to new products.

Causas do desmatamento da Amazônia: uma aplicação do teste de causalidade de Granger acerca das principais fontes de desmatamento nos municípios da Amazônia Legal brasileira
(2009) DINIZ, Marcelo Bentes; OLIVEIRA JÚNIOR, José Nilo de; TROMPIERI NETO, Nicolino; DINIZ, Márcia Jucá Teixeira
Many are the factors indicated by the pertinent literature concerning the causes of deforestation in Brazilian Legal Amazon. From endogenous aspects as the edafo-climatic conditions to aspects related to anthropic action, like the population movements, urban growth, and especially, the independent or induced actions of the different public and private economic agents who have acted in the region, historically configuring the processes of occupation of the land and economic exploitation of the Amazonian region. The objective of this article is to perform a causality test, in the Granger sense, in the main variables suggested as important that explain the deforestation of the Legal Amazon, in the period from 1997 to 2006. The methodology to be used is based on dynamic models for the panel data, developed by Holtz-Eakin et al. (1988) and Arellano-Bond (1991) who developed a causality test based on the seminal article of Granger (1969). Among the main results found is the empirical evidence that there is a bidirectional causality between deforestation and the areas of permanent and temporary cultures, as well as the size of the cattle herd.

Condicionantes socioeconômicos e ambientais dos clubes de convergência da renda na Amazônia Legal 1985 a 2007
(2011-12) SILVA, Gerson Medeiros da; OLIVEIRA JÚNIOR, José Nilo de; DINIZ, Marcelo Bentes
This paper analyzes the formation of convergence clubs in Amazonia in the period 1985 to 2007 conditional on socio-economic, institutional and environmental. The innovative nature of this work is to test the first time the importance of deforestation and environmental condition of the formation of convergence clubs in the Amazon. A methodology through the nonparametric estimation of kernel densities, the transition matrix and estimation of stochastic kernels to test the evidence of convergence between the municipalities. The results confirmed the hypothesis of convergence, large intra-sectional dynamics of income and the formation of three convergence clubs among the municipalities of legal Amazonia. Human capital appears as a major constraint and the cattle and livestock area has low significance in determining the rent for municipal. Deforestation and institutional variables were not significant for economic growth municipalities of Amazonia.

Desigualdade e heterogeneidade no desenvolvimento da Amazônia no século XXI
(2009-04) LIRA, Sérgio Roberto Bacury de; SILVA, Márcio Luiz Monteiro da; PINTO, Rosenira Siqueira
The deforestation of the Amazon forest is one of the most important environmental problems faced by the Brazilian government. The economic literature points to numerous factors responsible for deforestation, and many of these are, directly or indirectly, derived from federal spending. This article analyzes, through a panel data econometric model, how federal spending can influence, or mitigate, Amazonian deforestation. The state of Pará is used as a case study, as it presents the highest degree of deforestation among all Amazonian states.
