Artigo de Periódico Acesso aberto (Open Access) 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 daThis 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.Artigo de Periódico Acesso aberto (Open Access) 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 TeixeiraThere 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.
