| O presente estudo tem como objetivo identificar alguns fatos que influenciaram os preços da arroba do boi gordo recebido pelo produtor bem como realizar estimativas desses preços para um período de quatro meses a partir de maio de 2007. Para tanto, utilizou-se a metodologia idealizada por Box-Jenkins (1976). Os resultados demonstraram que a série em questão (01/1996-05/2007) apresenta uma quebra estrutural no período referente a janeiro de 2004, fator esse que levou ao corte da mesma, sendo considerado na análise o intervalo de fevereiro de 2004 a maio de 2007, apresentando 40 observações. Alguns acontecimentos podem ter influenciados os preços da arroba do boi gordo naquele momento, e um que merece destaque é o fato de que nesse período foram detectados... |

| O setor primário brasileiro é de grande importância para sua economia e a lavoura orizícola gaúcha está inserida nesse contexto, também com grande relevância, pois tem significativo número de produtores que auferem seus rendimentos dessa atividade. Entretanto, há uma redução de rentabilidade no setor atribuída às Importações Mercosulinas que, alegam os produtores brasileiros, pressionam os preços internos. Também, o crescimento da produção interna pode causar o mesmo efeito. Esse trabalho busca provar que o arroz importado do Mercosul e a Produção Gaúcha de arroz exercem influencia no preço interno e que as relações entre as variáveis ocorrem de forma curvilinear e não podem ser analisadas por métodos lineares. Para tanto, fez-se uso da estatística... |

| Given heavy dependence on rainfed maize production, Zambia must routinely cope with pronounced production and consumption volatility in their primary food staple. Typical policy responses include increased food aid flows, government commercial imports and stock releases, and tight controls on private sector trade. This paper examines recent experience in Zambia, using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes. In addition to an array of public policy instruments, the analysis evaluates the quantitative impact of two key private sector responses in moderating food consumption volatility— private cross-border maize trade and... |

| Com o aumento de preços e consumo do petróleo, tem-se procurado na biomassa alternativa energética renovável para sua substituição. Dentre as culturas capazes de atender à produção de insumo destinado à obtenção de energia renovável encontra-se a mamona. Objetivou-se, neste trabalho, conhecer o índice de variação estacional do preço da mamona, pois é essencial para a previsão de seu preço em determinada época do ano. Utilizou-se o preço da mamona recebido pelos produtores paranaenses e adotou-se a metodologia da média geométrica móvel centralizada de 12 meses, obtendo-se um padrão comportamental (sazonal). A análise mostrou que os preços tendem a ser maiores nos meses de janeiro a maio e, no período seguinte, a tendência é de queda de preços, coincidindo... |

| 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,... |

| This paper analyses the asymmetric price transmission and non-linear adjustment at the farm and retail levels in the Iran’s mutton market. We applied a multivariate threshold error correction mechanism for monthly price data. We tested the non-linear adjustment using sup-LR, sup-LM and sup-Wald tests. The results confirm the presence of non-linear cointegration relationship between the retail and farm prices. In short-run, the price transmission behavior reveals that reactions of both the retail and farm prices to positive and negative deviations from the long-run price spread are asymmetric. More specially, the retailers show more strong responses to the both positive and negative shocks imposed to the farmers. |

| This working paper synthesizes the theoretical and empirical literature on the use of cash transfers in response to food crisis situations, with particular attention to their use in situations that are exacerbated by volatile, often inflationary, commodity prices. The paper is designed for policymakers who are wondering if cash transfers might be an appropriate instrument in the context of 2008’s unstable commodity prices for both food and energy, but are unfamiliar with the literature and discussions surrounding the cash vs. food debate. After defining some key terms and presenting a brief review of the theory behind cash transfer use, the paper synthesizes evidence from studies that have evaluated past cash transfer programs. While the focus is on... |

| The uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decision-makers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time path of mitigation efforts as well as whether those efforts, by design, focus on effort or outcome. This paper considers two choices-price versus quantity controls and absolute versus relative/intensity emissions limits-demonstrating that price controls and intensity emissions limits favor certainty about cost over climate benefits and future emissions reductions. The paper then argues that in the near term, this favoritism is desired. |
