Índice de desenvolvimento rural dos municípios paranaenses: determinantes e hierarquização

The introduction of the productivity gains model in the Brazi-lian agriculture has caused important changes in the rural environment, affecting its development. The agricultural sector in Parana is part of this process and in this state, also, there have been significant shifts in the structure of production, which have had an indirect influence both economically and socially in the countryside. This essay, therefore, aims to measure the rural development rate in the cities of Parana and iden-tify the determining factors. The results have shown that, in a scale of 0 to 100, the average rural development rate is 43,63. 179 cities (44,86%) present rates above the mark mentioned and 220 (55,41%) are under this mark. By organizing the cities according to the development degree it was evident that more than half of the cities in the state have had low, very low or extremely low levels of rural development, a situation that calls for actions that aim to minimize the effects of the aspects which must be intensely worked on in order to improve life in the country and as a consequence, life in the city.

Dinâmica das exportações da América Latina: economias de escala ou dumping recíproco?

The main concern of this paper is investigated if the Latin American exports is explain for monopolist competition with increasing returns or oligopoly competition with reciprocal dumping. For these propose we used gravitational equation for Latin-American exports for differentiated and homogeneous products. For our econometric estimation we used an extensive sample of exports of 26 Latin-American countrys to 136 countrys importers of the rest of the world. Our results of the research are the following (a) The Latin-American exports for differentiated goods is explain by monopoly competition and increasing returns with free entry market (b) for homogeneous goods the behavior of regional exports is associated a oligopoly competition with reciprocal dumping (c) The homogeneous goods, with are associated with primary raw materials are yet very important for the economic growth of the Latin-American countrys.

ESTUDO DA DISTRIBUIÇÃO ESPACIAL DO SETOR AGROPECUÁRIO DO RIO GRANDE DO SUL

Considering the significant importance of agriculture for the State of Rio Grande do Sul economy, the present work aimed to examine the spatial distribution of agriculture in the State of Rio Grande do Sul in 2004, verifying the existence of clusters, as well as to analyze the level of correlation among the variables analyzed in the production function, using as endogenous variable the gross value of agricultural production. Thus, the Exploratory Analysis of Spatial Data was used as methodological basis. The results demonstrated the existence of positive spatial autocorrelation between towns and that the greatest values of production are found in towns situated in the North and Southeast regions. The maps of clusters allowed to verify the existence of two low-low clusters, situated in the South and Northeast of the state, and three high-high clusters in the North and Northeast region, where there is predominance of small properties, grape cultivation and high gross value of production.

Transformações na estrutura produtiva da economia paranaense nos anos 80 e 90

Este artigo apresenta a evolucao da estrutura produtiva da economia paranaense nas decadas de 1980 e 1990. Para tanto, estimou-se uma serie de 5 matrizes de insumo-produto para os anos de 1980, 1985, 1990, 1995 e 1999, divididas em 32 setores, a partir das quais foram calculados o campo de influencia, os indices de ligacao de Hirschman-Rasmussen e puros e os multiplicadores setoriais. Esses indicadores permitiram identificar, alem dos setores-chave, a evolucao das relacoes economicas e interindustriais no periodo. Os resultados mostraram tendencia de diversificacao da estrutura produtiva estadual e de maior abertura comercial, refletida nos menores indices de ligacoes internas e nos multiplicadores de producao.

O PASS-THROUGH DAS VARIAÇÕES DA TAXA DE CÂMBIO PARA OS PREÇOS DE EXPORTAÇÃO DE SOJA

Este trabalho tem como objetivo estimar o coeficiente de pass-through das variacoes da taxa de câmbio para os precos de exportacao da soja no Brasil, no periodo compreendido entre 1994 a 2004. Para chegar aos resultados utilizou-se econometria de series de tempo para mensurar os coeficientes de pass-through da taxa de câmbio para os precos de exportacao. O resultado revelou um grau de pass-through incompleto, da ordem de -0,34, indicando que a politica cambial pode ocasionar impactos positivos sobre o volume das exportacoes, mas, nao deve ser a unica politica de estimulo.

A IMPORTÂNCIA ECONÔMICA DO AGRONEGÓCIO PARA A REGIÃO SUL DO BRASIL

O objetivo principal deste artigo e analisar o nivel de desenvolvimento do agronegocio ou complexo agroindustrial na Regiao Sul do Brasil para os anos de 1985, 1990 e 1995, utilizando matrizes de insumo-produto inter-regionais. Sao apresentados resultados sobre a composicao e sobre as principais caracteristicas dos fluxos inter-regionais do agronegocio na Regiao Sul. Os resultados indicam que houve um aumento na participacao da Regiao Sul no agronegocio do Brasil de 28,7% em 1985 para 29,6% em 1995 e que a parcela deste setor no Produto Interno Bruto da Regiao Sul foi de pouco menos de 50% em 1995.

O Comportamento do Preço da Terra Agrícola: um modelo de painel de dados espaciais

This study analyzes the behavior of the agricultural land price in the municipalities of Parana State over the period 1999-2011. After literature review of the main studies of this field, the determinants of land price and methodology to be used were identified. For this purpose, we estimate the empirical model for price of agricultural land through spatial data panel. The results show that main statistically significant variables to explain the price of agricultural land in Parana State are the gross value of agricultural production, asset valuation, total financing in agriculture, ratio municipal investment-deterincome, percentage of planted soybeans in the municipality and the incorporation of spatial dependence on land prices. These variables can explain around 84% of the prices and indicate that the data presented great intrapanel fit, and the spatial effects would be more intense in the municipality itself and in relation to the whole. The proposed model, specially, advanced in structural terms, by incorporating data from all 399 municipalities in Parana. Empirically, the study advanced by estimating through panel data and considering the influence of spatial effects on the agricultural land price, highlighting the importance of the location and neighborhood in the price determination.

Consumo de tabaco entre universitários: uma revisão sistemática

Objetivo: identificar como o consumo de tabaco entre universitarios e abordado na literatura. Metodos: foi realizada uma revisao sistematica de janeiro de 2004 a dezembro de 2013.

INVESTIMENTO ESTRANGEIRO DIRETO NO BRASIL: EFEITOS DIRETOS E ESPACIAIS SOBRE O CRESCIMENTO ECONÔMICO

This paper aims to analyze the direct and indirect effects (regional spillover) of foreign direct investment in the Brazilian states on the rate of economic growth. First, was used the procedure of spatial analysis to verify the presence of spatial correlation among the states, and then, we apply econometrics of panel data with spatial weights. The results suggest that foreign direct investment can affect economic growth directly. Also is possible to observe a regional spillover effect positive. However, this relationship demonstrates sensitive to changes in the specification.
