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.

Curva ambiental de Kuznets e desenvolvimento econômico sustentável
(2006-09) ARRAES, Ronaldo de Albuquerque e; DINIZ, Marcelo Bentes; DINIZ, Márcia Jucá Teixeira
The motivation of this article bases on the controversy in the recent literature about economic growth, sustainable development and environmental protection, started with the empirical evidences presented by Grossman and Krueger (1995, 1996), where the relationship between per capita GDP and emission of pollutants takes the shape of an inverted–U, denominated in the literature as Environmental Kuznets Curves (EKC). This article differs from others by contributing with further explanation stemming from economic development indicators. Despite being contested by many authors, several structural interpretations of EKC have been strongly sustained under ad hoc shield. The concern about such stylized fact is whether or not the economic growth itself generates an automatic protection to the environment, consequently to the maintainable development. Based upon panel data for countries, it is verified that the variables that denote sustainable economic development present a weak relationship with per capita GDP to support an EKC representation. There are also evidences for environmental curves in cubic format, which means rejection of EKC, besides most of the development indicators pointing out for divergences among countries.
