| 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... |

| 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. |

| 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... |

| 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... |

| O objetivo deste trabalho é propor uma metodologia que permita medir os efeitos de barreiras não-tarifárias sobre o desempenho exportador de um setor específico. Para testar a metodologia, foi analisada a ocorrência de eventos/barreiras sanitárias sobre nas exportações brasileiras de carne bovina (cortes especiais), destinadas à União Européia. A metodologia compreende a estimação de um modelo econométrico para vendas externas associado a um modelo de intervenção. O período analisado compreendeu janeiro de 1992 a dezembro de 2000. A maior parte das variações no volume e no preço de exportação foi explicada pelas variáveis selecionadas (taxa de câmbio, preço do boi gordo, renda do Brasil, preço dos concorrentes, entre outras). Os resultados apontam efeito... |
