| Very little attention has been given to the modeling of yield distribution for crops and regions in which yields exhibit irregular behavior. We undertake a statistical case study of Texas upland cotton and propose an alternative mixture distribution based on regime-switching model in which the conditional distribution of yield depends upon an observable drought index. The results show that the mixture distribution model provides a better fit to the data than conventional parametric distributions and produces higher implied premium rates than the current published Group Risk Plan insurance rates in more than two-thirds of Texas counties examined. |

| Recently, the European Commission proposed to introduce several risk management tools in the rural development pillar 2 of the CAP. One of them consists in providing co-financing support to mutual funds compensating farmers who experience a severe drop in their farm income. This paper analyses this new farm income stabilization tool for the Walloon region in Belgium, considering separately three groups of farms (crop, dairy and cattle farms). Relying on FADN data from 1997 to 2007, this analysis focuses on estimating the probability that such regional mutual funds would need to intervene to compensate farm net incomes and, in that case, the expected amount of each farm income compensation and the total expected amount of compensation. The budgetary... |

| Es ist seit langem bekannt, dass das Wetter den Hauptunsicherheitsfaktor in der pflanzlichen Produktion darstellt. Seit einiger Zeit wird der Einsatz von Wetterderivaten zur Absicherung gegen wetterbedingte Ertragsschwankungen diskutiert. In diesem Beitrag wird am Beispiel ei-nes getreideproduzierenden Betriebes in Brandenburg unter Verwendung von realen Ertrags- und Wetterdaten mit Hilfe einer stochastischen Simulation die risikomindernde Wirkung quan-tifiziert, die durch den Einsatz von Niederschlagsoptionen erzielt werden kann. Dabei wird die Hedging-Effektivität durch das Kontraktdesign (Index, Strike-Preis, Tick-Size) gesteuert. Das Basisrisiko der Produktion und das geografische Basisrisiko verbleiben jedoch in jedem Fall beim Landwirt. Ziel ist es,... |

| The present study sets up a thought experiment calibrated to represent risks of a high-risk production activity (farming), and investigating whether the structure of risk aversion (i.e., the changes in absolute or relative risk aversion associated with changes in wealth) can be estimated with reasonable precision. Findings strongly suggest that typical production data are unlikely to allow identification of the structure of risk aversion. A flexible utility parameterization is found to worsen technology parameter estimates. Findings also indicate that even under a restricted utility specification, the quality of utility parameters estimated from small samples is very poor. |

| O presente estudo tem como objetivo, usando simulações, analisar as operações de hedge com contratos de boi gordo da Bolsa de Mercadorias & Futuros (BM&F). As simulações compreenderam o período de 2001 a 2006, sendo que em todos os anos os contratos simulados são do mesmo vencimento, outubro com entrada na operação no mês de março, em três estados diferentes: São Paulo, Paraná e Mato Grosso do Sul. A estratégia de utilização do mercado futuro mostrou-se viável, desde que acompanhada do conhecimento de fatores que interferem no mecanismo de comercialização: o comportamento da base e do risco de base em cada região. O conhecimento e o acompanhamento destes fatores, através dos anos, tem fundamental importância na tomada de decisão para operações no... |

| The Supplemental Revenue Assistance Payments (SURE) program, introduced in the 2008 Farm Bill, provides disaster aid payments to producers in counties eligible for disaster payments and individual producers with crop production losses that exceed 50% of their expected yields. We show that the program’s "rules of the game" create moral hazard and adverse selection incentives. Then, we empirically analyze possible moral hazard and adverse selection behavior in response to the SURE program by corn, soybean, and wheat producers. Results suggest that recent increases in crop insurance participation may be due to increased moral hazard and adverse selection incentives. |

| The study evaluates the effectiveness of a catastrophic drought-index insurance developed by applying two alternative methods - the standard regression analysis and the copula approach. Most empirical analyses obtain estimates of the dependence of crop yields on weather by employing linear regression. By doing so, they assume that the sensitivity of yields to weather remains constant over the whole distribution of the weather variable and can be captured by the effect of the weather index on the yield conditional mean. In our study we evaluate, whether the prediction of farm yield losses can be done more accurately by conditioning yields on extreme realisations of a weather index. Therefore, we model the dependence structure between yields and weather by... |

| Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a great deal of information in this regard, although specific to the conditions of each study. In light of this, WTP estimates for traceability characteristics differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta-analysis allows us to analyze consistency across studies and control for factors thought to drive variations in WTP estimates. The meta-analysis has been conducted using 23 studies that, in aggregate, report 88 valuations for WTP. Our results, aside from releasing unconditional information on the WTP for... |
