In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. This paper focuses on one of these guidelines -- the Panel's call for the "temporal averaging" of willingness-to-pay (WTP) responses obtained from CV surveys as one method for increasing their reliability. The panel suggested: "Time dependent measurement noise should be reduced by averaging across independently drawn samples taken at different points in time. A clear and substantial time... |

El Nino events are likely to affect maple syrup production since it is very sensitive to weather patterns. A statistically significant direct correlation has not been found in our preliminary analysis, however. This may be because many other factors affect production and because weather anomalies also occur in non-El Nino years. Few defensive activities are available to maple syrup producers to alleviate the negative impacts of weather anomalies on their production. Hence, the value of El Nino-Southern Oscillation (ENSO) forecasts to them is likely to be low, even if a clear correlation between productivity and ENSO events was eventually found. Overall, small welfare impacts of El Nino weather events are expected from their impact on the maple syrup... |

In current study, an irrigation examination and acquisition of environmental water in Kor River fields, that is dominated from Doroudzan dam to Bakhtegan Lake, was done by an integrated economy-environmental model. The model was considered by economic, hydrologic and agronomic components. In the economic component, an optimal harvesting of water was done using non-linear programming in two scenarios; with and without environmental water constraint. Solutions from simulation of environmental data in the hydrologic component, was used as initial data in the economic component. In the agronomic component, actual crop yield in wet, normal and dry years was determined using the relationship between crop yield and irrigation water amount. Results showed that,... |

Marketing of milk and meat in Denmark is dominated by two large cooperatives, Arla Foods in the dairy sector and Danish Crown in the pork sector. Members in these cooperatives practically have no possibility for price risk management on their main product. Futures markets for dairy and pork are not utilised, and it is suggested that the reason is prohibitively large basis risk. The events following the global financial crisis suggest increased need for price risk management in Danish agriculture. Since futures markets do not seem to be a viable solution, the paper explores an alternative. Reallocation of price risk among members in marketing cooperatives. Endowing members with a forward contracted share of delivery, and allowing for transfer at a market... |

In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the Panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. One of the Panel's recommendations was that CV surveys should employ a referendum approach. This method describes a choice mechanism that asks each respondent how they would vote if faced with a particular program and the prospect of paying for the program through some means, such as higher taxes. The Panel also recommended that CV referendum questions which commonly use only "for" or... |

In developed countries governments aim to increase the market share of organic products. Assuming that organic farming creates a positive externality, we address the question of how this environmental benefit can be internalized best. Using the concept of heterogeneous producers and consumers we compare two policy options to enhance organic supply and demand with respect to their efficiency and distributional effect: First, we analyze the effect of a supply-side oriented policy like a subsidy on organic production. Second, we compare this policy measure to a demand-side oriented information policy, which aims to enhance the acceptance and identification of an organic food label. Third, we assume a mix of both policy measures. The main findings of this... |
