| While global analytical approaches to agricultural trade liberalization yield large gains for most economies, there are substantial variations in the policy regimes across commodities. To clarify the multiplicity of distortions and impacts, the World Bank's Trade Department undertook a series of commodity studies. The studies highlight the important challenges faced by negotiating countries in the Doha Round of the World Trade Organization (WTO) trade negotiations. The studies provide a sharper look at the North-South dimensions of the agricultural trade debate, with the North's trade barriers, domestic support, and tariff escalation. They also underscore the South-South challenges on border protection and the reduced rural income opportunities for the... |

| This research was conducted in shops self-service of Pachuca and local commerce of Zacualtipán, were recorded prices of 24 products: rice, tortilla, tomato, lemon, jalapeno chile, milk, eggs, ham, sausage, beef, chicken meat, toilet paper, soap powder, toilet soap, toothpaste, beans, onions, potatoes, avocado, orange, banana, oil, salt and sugar. The dates for consulting prices were: July 26, 2007, on January 25 and May 29, 2008. The importance of this study is the comparative analysis and trends in prices. The shops self-service offer 9.7% cheaper in 62.5% of the products. The local commerce offer the 12.7% cheaper than the shops self-service in beans, onions, potatoes, avocados, bananas, oil, salt and sugar. During the July 26, 2007 to May 29, 2008,... |

| Atualmente as commodities representam uma significativa parcela do Produto Interno Brasileiro. Entretanto, o volume exportado pode sofrer influência significativa pelo preço apresentado no cenário internacional, alterando sensivelmente a remuneração do produtor. Dentro deste contexto, o presente trabalho se propõe a analisar o comportamento dos preços recebidos pelo produtor das principais commodities agrícola brasileiras: cacau, café, cana de açúcar, laranja e soja. Para tanto, procurou-se realizar uma previsão ex-ante para os preços destes produtos a partir da metodologia ARIMA. Os resultados obtidos fornecem uma ferramenta de análise para o mercado destas commodities, na medida em que demonstram a tendência dos preços para um horizonte de curto prazo,... |

| Abstract: The objective of this work was to develop sequence-characterized amplified region (Scar) markers to identify the B, Q, and native Brazilian biotypes of the sweet potato whitefly [Bemisia tabaci (Hemiptera: Aleyrodidae)]. Random amplified polymorphic DNA (RAPD) amplification products, exclusive to the B and Brazilian biotypes, were selected after the analysis of 12,000 samples, in order to design a specific Scar primer set. The BT-B1 and BT-B3 Scar markers, used to detect the B biotype, produced PCR fragments of 850 and 582 bp, respectively. The BT-BR1 Scar marker, used to identify the Brazilian biotype, produced a PCR fragment of 700 bp. The Scar markers were tested against the Q biotype, and a flowchart was proposed to indicate the decision... |

| This report provides baseline projections for international supply, demand, and trade for major agricultural commodities to 2007. It is a companion report to USDA Agricultural Baseline Projections, providing the foreign country details supporting those projections. Projections of strong global economic growth, particularly in developing countries, combined with more open foreign markets and the emergence of China as a major bulk commodity importer, support strong projected gains in U.S. farm exports. The value of total U.S. agricultural exports is projected to rise from a record $57.3 billion in FY 1997 to nearly $85 billion in 2007. The projections were completed based on information available as of December 1997, and reflect a composite of model results... |

| International trade has increased, in the last few decades, however the economic divide between the advanced economies in the North of the world and the less developed of the South has increased. In the current state of affairs, characterised by the increasing integration between the commodities and service sector, capital and labour sector and the financial markets, diverse initiatives are arising in developed countries, aimed at supporting developing countries, under the impulse from a civic society increasingly concerned about the problems that trouble them. These initiatives, which most importantly include the Fairtrade and the Ethical Finance movements, excel the welfarism that has shaped the policies of the developed countries, and promote ways of... |

| The purpose of the paper was to study if the dynamics of the Brazilian cattle stocks can be better explained by systemic endogenous factors or either by exogenous changes on beef demand. The conclusion, as proposed by the theory of the cattle cycle, was that systemic factors related to the adoption of the stabilization program in 1994 were apparently more important in explaining the stagnation of the Brazilian herd since 2000. The main policy implication of this conclusion is that it seems to have a space for stabilizing de dynamics of the system through adequate public policies. The methodology used was system dynamics which allows to trace the critical feedback loops that drive de cattle cycle and to identify possible leverage points in the system,... |

| Fungi are common inhabitants of plants and plant-derived products. Some of these fungal species are potentially dangerous to human health since they are able to produce chemical substances that alter normal physiological activity. There are no studies about natural mycoflora associated with coffee beans in Colombia, and nothing is known about the presence and abundance of toxigenic fungal species in Colombian coffee. In this study 5,000 coffee beans were studied by plating them on potato-based artificial culture medium and it was shown that potentially toxigenic fungal taxa (mostly from genera Aspergillus, Fusarium, Penicillium), are currently found in Colombian coffee beans. This is true for all steps of coffee processing, from berries in trees to toasted... |

| In despite of the several advantages for exporting ground and roasted coffee instead of green coffee, namely employment and value gains, there are many limitations to the private efforts. Effective attempts have been discouraged by large and stable national market, high risks associated to the international market, and a frightening bureaucracy. Even so, some progress has been reported in recent years as is shown in this paper, based on interviews with Brazilian export agents, industries and cooperatives. Some restrictions are inherent to the enterprises, such as managerial questions and innovation aptitude, while others are systemic. Suggestions to improve processed coffee exports are presented. |

| This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that financial speculation is poorly significant in modelling returns in commodities futures while macroeconomic factors help explaining returns in commodities futures. Moreover, spillovers between commodities are present and the conditional correlations among commodities are high and time-varying. |
