Análise de econometria de dois sistemas naturais de tratamento de água residuária na suinocultura

The aim of this work was to develop a detailed econometric analysis to compare a constructed wetland system - combined model, and a waste stabilization pond system - facultative pond, as a function of six different sizes of finishing pig farms and two waste management systems - wet and dry. The constructed wetland system using dried waste management showed the best economic results. This finding is due to the low-cost implementation a year both per animal and per kilogram of meat. This system also required the smallest area for waste treatment. The use of stabilization pond with wet waste management system showed a lower implementation cost a year per animal and per kilogram of meat, but it required large areas. The econometric analysis of both systems of wastewater treatment revealed an economy of scale.

Uma análise espacial do crescimento econômico dos municípios paulistas no período de 2000-2010

O presente trabalho tem como objetivo fazer uma análise do crescimento econômico dos municípios paulistas entre os anos de 2000 e 2010 baseando-se, principalmente, no modelo de Glaeser et al. (1995). Essa análise será feita relacionando o crescimento com variáveis socioeconômicas como a renda, infra-estrutura, emprego e educação. Além disso, serão acrescentadas técnicas da econometria espacial para verificar os efeitos da aglomeração e possíveis externalidades provocadas pelo crescimento. Por fim, será feita uma comparação com o trabalho de Vieira (2008) que fez uma análise semelhante dos municípios paulistas para o período de 1980 a 2000

Um modelo para a criminalidade no município de São Paulo em 2001

This work aims to estimate an empirical model for three kinds of crime in Sao Paulo city: homicides, robberies and car thefts. It uses as geographical units the areas belonging to each police districts and takes in account spatial effects among the variables. The results show important differences when we deal with crime against people and crime against property.

Implementing inflation targeting in Brazil: an institutional analysis

The paper shows the advantages and handicaps of implementing an inflation target (IT) regime, from a Post-Keynesian and, thus, an institutional stance. It is Post-Keynesian as long as it does not perceive any benefit in the mainstream split between monetary and fiscal policies. And it is institutional insofar as it assumes that there are several ways of implementing a policy, such that the chosen one is determined by historical factors, as it is illustrated by the Brazilian case. One could even support IT policies if their targets were seen just as “focusing devices” guiding economic policy, notwithstanding other targets, as, in the short run, output growth and employment and, in the long run, technology and human development. Nevertheless, an IT is not necessary, although it can be admitted, mainly if the target is hidden from the public, in order to increase the flexibility of the Central Bank.

Curva de Kuznets ambiental para o Estado de Mato Grosso

Issues concerning deforestation have become a crucial theme in the environmental world debate. In this picture, Mato Grosso State has become an unfavorable example because it represents 36% of the accumulated deforestation in the Brazilian Amazon. In order to investigate the relationship between deforestation and income growth, this paper estimates an Environmental Kuznets Curve (EKC) for 139 cities of Mato Grosso through spatial econometrics. Using data for the year 2006, we estimate an EKC for the deforestation per capita against income per capita and other variables controlling the spatial effects. The preliminary results indicate that an EKC exists in a reversed U shape, i. e., the income growth reduces environmental effects from the maximum point. However, introducing a cubic term for the income, the economic growth would not reveal any relationship with the deforestation in the Mato Grosso State.

Economic growth and the quality labour market of jobs created: a Brazilian case and some implications to Latin America

An outcome of economic growth is increased employment, but this should not be the only measure to assess a country's labour market, it is also important to verify whether the jobs created are considered good jobs. Thus, this study analyses the Brazilian labour market from 2000 to 2009, in terms of the quantity and quality of jobs generated in this period. To this end, a descriptive analysis was performed, in addition to an evaluation using econometrics and the data envelopment analysis (DEA) technique. The results of the research indicated that the Brazilian labour market is growing in terms of its quality.
