| Social protection aims to provide a national platform for smoothly transitioning from a chaotic collection of shock responses to an institutionalized system for risk and non-risk management. For the poorest, the transition aims to move away from ad hoc, unpredictable relief to national safety nets that deliver timely, multi-year, guaranteed and predictable transfers. Social protection has to face particular challenges in chronically poor, shock-prone countries where the distinction between the chronic and transitory poor is often blurred. Other conceptual and programmatic issues also need further investigation. For filling these gaps, a research agenda articulated in ten thematic areas is proposed. |

| The overall aim of this study is to empirically investigate the cost structure of a management agreement type agri-environmental instrument and to identify factors for cost variation over space and time. We control for the actual level of compliance by using compliance weighted average scheme cost ratios. Beside technological and economic performance measures, we also incorporate risk proxies. In addition, we consider unobserved heterogeneity or path dependency with respect to unknown administrative, spatial and farm specific factors. Hence, we try to disentangle random and fixed scheme cost effects by applying a bootstrapped mixed-effects regression approach using the empirical case of the Environmental Stewardship Scheme in the UK. Regional and sectoral... |

| The risks confronted by grain and cotton farmers are of particular interest, given the changing role of the Government after passage of the 1996 Farm Act. With the shift toward less government intervention in the post-1996 Farm Act environment, a more sophisticated understanding of risk and risk management is important to help producers make better decisions in risky situations and to assist policymakers in assessing the effectiveness of different types of risk protection tools. In response, this report provides a rigorous, yet accessible, description of risk and risk management tools and strategies at the farm level. It also provides never-before-published data on farmers' assessments of the risks they face, their use of alternative risk management... |

| This study analyzed the effects that the use of crop insurance products and marketing alternatives had on the gross revenue per acre for an individual farm in Cass County. Crop insurance products and marketing strategies were analyzed individually to determine if they were effective in minimizing down side risk, and combined to determine if integration created synergies. A whole farm scenario analysis was run that included integrated strategies that implemented the same insurance coverage and marketing alternatives for each crop. Several general conclusions can be drawn for situations similar to the representative farm. When analyzed at the individual crop level, the use of crop insurance at the 65 percent level minimizes down side risk in wheat and corn,... |

| A number of challenges exist for genetically modified (GM) crop development at the production level. Contract strategies can resolve these challenges. Contracts can be designed to induce legal adoption of GM wheat by varying technology fees, violation detection, and penalties. The primary objective of this research is to analyze contracting strategies to determine terms to minimize technology agreement violation and to induce legal adoption of GM wheat. A simulation model of a crop budget for Hard Red Spring wheat was developed. Results illustrate that contracts can be designed to induce desired behavior. Technology fee, probability of detection, and the level of non-GM premium were the most notable factors influencing adoption decisions. |

| Abstract: This study explores different procedures to estimate price risk in commodity markets. Focusing on Brazilian agricultural markets, the paper proposes to assess both dispersion and downside risk measures using five different approaches (volatility, coefficient of variation, lower partial moments, value at risk and conditional value at risk). Results suggest that some commodities have large price variability but small downside risk, while other commodities show small price variability and large downside risk. Thus, there is no single answer to the question of which commodity exhibits more price risk, but rather distinct answers depending on how risk is perceived by different individuals. These findings are relevant for agents in the agricultural... |

| Los problemas ocasionados por las inundaciones en México se han incrementado de manera considerable, específicamente en el estado de Tabasco las pérdidas por inundaciones son preocupantes. Por esta razón resulta de gran interés la construcción de un índice que mida el riesgo de inundación en una área determinada. En el presnte trabajo se construye un indicador del riesgo de inundación en el estado de Tabasco, para esto se consideran los siguientes tres componentes: la vulnerabilidad, el costo y el peligro. Con el componente de vulnerabilidad se mide que tan susceptible es el área de interés frente a una inundación y para esto se toma en cuenta tanto elementos sociales como naturales, en el primero se considera la disposición de los servicios con los que... |

| The optimisation of production plans is an important topic in agriculture, often related to diversification and specialisation as the classical instruments of coping with production risk. Although the measurement of embedded risk is often inaccurate, it is nevertheless necessary for decision making to describe the common behaviour of different variables in a model. Imprecisely defined relationships influence the “right” choice, why it is important to find a good approximation of the real circumstances. In financial science, copula functions are frequently used instead of correlation coefficients to model joint price behaviour, because of the possibility to link the marginal distributions on multifarious ways. By now, agricultural science makes less use of... |

| The use by farmers of futures contracts and other hedging instruments has been observed to be low in many situations, and this has sometimes seemed to be considered surprising or even mysterious. We propose that it is, in fact, readily understandable and consistent with rational decision making. Standard models of the decision about optimal hedging show that it is negatively related to basis risk, to quantity risk, and to transaction costs. Farmers who have less uncertainty about prices have a lower optimal level of hedging. If a farmer has optimistic price expectations relative to the futures market, the incentive to hedge can be greatly reduced. And finally, farmers who have low levels of risk aversion have little to gain from hedging in terms of risk... |

| This study contributes to the understanding of behavioural responses to climate change induced extreme weather events. It suggest a microeconometric method for measuring flooding related risk preferences of affected individuals. The method is outlined using the empirical case of agricultural production in floodplains of the UK over 28 years. A quasi-experimental approach to measure differences in the risk attitudes of farmers located in high flooding risk areas versus farmers located in low flooding risk areas is followed. Changes in flooding risk related behaviour over time is analysed and marginal effects of different individual and disaster related characteristics for this behaviour are investigated. Beside a moments based risk estimation approach the... |

| German hog production responds only very limited to price fluctuations in the pork market. The hog production concentrates in a few regions though it does not depend on special natural conditions. Furthermore, the production volume does hardly vary over time. Relatively high market risks, sunk costs, and the flexibility of the decision maker to defer investments characterize decision problems hog production. Thus the real option approach is chosen to explain the inertia in production capacity. Using panel data of specialised hog farms from the German farm accountancy data network (FADN) an empirical investment model is estimated. Formally, the model has the structure of an ordered probit model. This approach allows to test for economic hysteresis in the... |

| Ethanol production has recently surged in response to biofuel policies and increased fossil oil prices. We develop a partial equilibrium model focused on U.S. corn-based ethanol production with downside risk-averse farmers to assess the consequences of ethanol production on agricultural volatility. We report substantial effects on the distribution of corn prices with increases in the variance of prices received by farmers. Risk-averse corn farmers still benefit due to the higher mean price effect. From a methodological perspective, this analysis reveals that downside risk aversion may be important. |
