The Determinants of the Brazilian Farm Prices
Provedor de dados: 31
Autores: Spolador,   Humberto Francisco Silva; Barros,   Geraldo Sant'Ana de Camargo; Bacchi,   Mirian Rumenos Piedade.
The findings presented in this paper come from our study of the effects of Brazilian macroeconomic policy on the Brazilian Farm [product] Price Index using an adapted version of Frankel’s (1986 &amp; 2006) theoretical model. The study examined the connection between Brazilian farm prices and external variables (worldwide importation of agribusiness products, international commodity prices, and foreign real interest rates) and between Brazilian farm prices and domestic variables (GDP, the real exchange rate, and local interest rates).

he rapid growth in consumer demand for livestock offers an opportunity to reduce poverty among smallholder livestock farmers in the developing world. These farmers’ opportunity may be threatened, however, by competition from larger-scale farms. This report assesses the potential threat, examining various forms of livestock production in Brazil, India, the Philippines, and Thailand. Findings show that the competitiveness of smallholder farms depends on the opportunity cost of family labor and farmers’ ability to overcome barriers to the acquisition of production- and market-related information and assets. Pro-poor livestock development depends, therefore, on the strengthening of institutions that will help smallholders overcome the disproportionately high...

A balança comercial do agronegócio brasileiro de 1989 a 2005
Provedor de dados: 31
Autores: Barros,   Geraldo Sant'Ana de Camargo; Silva,   Simone Fioritti.
This study aims to analyze the agribusiness contribution to Brazil’s trade balance. A new classification of the agribusiness trade balance was proposed and used to analyze the aspects of the exported products –agricultural products, products of animal origin, industrialized foods and imported inputs – represented by fertilizers. Imports and exports vector autoregression models were used to explain the behavior of these variables. An increase of 1% in the attractiveness – product of the exchange rate by the international prices – boosts immediately the exports of non processed agricultural products by 1.71%, stabilizing at 2% after some trimesters. The attractiveness explains 60 to 74% of the forecast error variances of these exportats. It is noted that an...

O EFEITO DAS IMPORTAÇÕES MUNDIAIS SOBRE AS EXPORTAÇÕES DO AGRONEGÓCIO BRASILEIRO – UMA ANÁLISE EMPÍRICA PARA O PERÍODO 2000/2007
Provedor de dados: 31
Autores: Spolador,   Humberto Francisco Silva; Barros,   Geraldo Sant'Ana de Camargo.
Ao longo do período 2000/2007 o setor externo do agronegócio brasileiro encontrou uma conjuntura altamente favorável para o aumento de suas exportações, pois se combinou uma situação de forte expansão da economia mundial com elevação dos preços internacionais de commodities. No âmbito interno, os ganhos de produtividade permitiram o avanço das exportações, enquanto que a valorização cambial, iniciada em meados de 2004, praticamente eliminou os efeitos positivos da elevação dos preços internacionais. Esse trabalho mostra que, a despeito dos efeitos negativos da valorização cambial, o crescimento das importações mundiais teve efeito relevante (em torno de 20%) no aumento das exportações brasileiras do agronegócio entre os anos de 2000 e...

Contratos de opção: análise do potencial de sustentação de preços para o mercado de arroz
Provedor de dados: 31
Autores: Adami,   Andreia Cristina de Oliveira; Barros,   Geraldo Sant'Ana de Camargo; Bacchi,   Mirian Rumenos Piedade.
An economic model was developed to analyze the put option contract role to stabilize prices in the paddy market. The possibility of using Federal Government Acquisitions (AGF) to complement the option instrument was considered. The role of the options was to reduce the risks of storing the product for later sale. The model is applied to analyze the option instrument implementation in the 2004/05 season. A two week demand for rice was estimated for the Brazilian market. The results show that the market prices go up when the government acts through the AGF. The options serve the purpose of making prices follow a compatible path. It was estimated that the probability for the option owners exercise their options is greater when the AGF are not used. One can...

Environmental regulation and international trade patterns for agro-industrial under a South-North Perspective
Provedor de dados: 31
Autores: Feix,   Rodrigo Daniel; Miranda,   Silvia Helena Galvao de; Barros,   Geraldo Sant'Ana de Camargo.
This paper aims at examining the relation between the international trade and the environment, particularly focused on sensitive agribusiness sectors. It consists on an empirical test to the conflicting positions supported by economists, some following the traditional approach (trade-off or neoclassical), while others supporting the Porter’s hypothesis, which considers that impacts of the stricter environmental regulation can benefit the trade competitiveness. A Heckscher-Ohlin- Vanek model was applied to net exports as the dependent variable. The agricultural products analyzed were total agriculture, rice, maize, soybean, wheat, dairy and swine; run for 97 countries, divided as developing and developed, in a cross-section approach. This modeling allows...

Diversification as a Form of Risk Management in Agriculture
Provedor de dados: 31
Autores: de Zen,   Sergio; Peres,   Fernando Curi; Barros,   Geraldo Sant'Ana de Camargo.
The objective of this study is to show the importance of diversification in the risk management process. The study areas are: Mato Grosso, with large properties, and Rio Grande do Sul with small. The developed activities are annual cultures and cattle for slaughter. The hypotheses of the work are: a) rural producers diversify their activities using modern techniques. b) Diversification has been efficient in the producers' risks reduction. c) Producers tend be as effective as possible, though they differ in the rates of risk aversion. The MOTAD and E-V models were used.

Risco no mercado de arroz em casca
Provedor de dados: 31
Autores: Adami,   Andreia Cristina de Oliveira; Barros,   Geraldo Sant'Ana de Camargo.
O presente trabalho avaliou as características das séries de retornos, normalmente encontradas em séries financeiras, para dados do mercado de arroz em casca ao produtor do Rio Grande do Sul. Um modelo da classe GARCH (1,1) tipo VaR foi utilizado para obter previsões da variância condicional e verificar o risco incorrido pelas posições comprada e vendida no mercado de arroz em casca. Foram realizadas previsões fora da amostra do tipo VaR para o risco de mercado para um mês à frente (um passo a frente). A taxa de falha calculada foi de 6,45% - número de vezes que o valor observado excedeu o valor esperado – pois, o modelo falhou em 2 das 31 previsões obtidas, sendo que, uma das 31 previsões excedeu os menores valores previstos e 1 excedeu os maiores valores...

Futuros agropecuários em portfólios de máxima utilidade esperada
Provedor de dados: 31
Autores: Silveira,   Rodrigo Lanna Franco da; Barros,   Geraldo Sant'Ana de Camargo.
This study investigates the composition of maximum expected utility portfolio, considering stocks, bonds, gold, dollar and agricultural futures contract, between August of 1994 and December of 2007. From the optimal combinations of risk-return (calculated by Markowitz algorithm) and the use of a quadratic utility function (with different levels of risk aversion), were obtained portfolios that maximizes expected utility. The commodity futures were not present in the maximum expected utility portfolios for the complete period, 1994-2000. However, with division of sample in two and three periods, the commodity futures were included in these portfolios during the 2000s. Furthermore, in general, with the risk aversion increase, the participation of these papers...

Supply and Demand Shocks and the Growth of the Brazilian Agriculture
Provedor de dados: 31
Autores: Barros,   Geraldo Sant'Ana de Camargo; Spolador,   Humberto Francisco Silva; Bacchi,   Mirian Rumenos Piedade.
In the last decades the Brazilian agriculture had a strong growth. Our hypothesis is that most of that growth may be attributed to two general factors, which may conveniently be related to two types of shocks acting upon agriculture: demand-related and technological supply-related shocks. Demand shocks are originated both from domestic economy but also from external markets. We use Blanchard &amp; Quah (1989) type of methodology to test the relative importance of supply and demand shocks on Brazilian agricultural growth. Our results indicate that supply and demand shocks have permanent effects upon agricultural output and prices. We estimate that the agricultural output growth in Brazil is attributed in large proportion to yield increases. We argue that...
