| We examine the spatial and dynamic implications of policies aimed at encouraging carbon sequestration in agricultural soils. We consider incentive mechanisms to encourage the planting of energy multi-annual crops that allow higher carbon sequestration rates for a longer period of time. By using a dynamic micro-economic model, we simulate the sequence of crop plantings over a given time horizon and investigate different payment mechanisms (per-ton or per-hectare). We discuss their implications in terms of regulation policy and efficiency. This model is then applied to the Central Plains of Thessaly, Greece to assess the marginal costs of carbon sequestration and the optimal timing of switching to multi-annual energy crops. To do so, we couple the dynamic... |

| Given the current situation with the high price of oil (an average of $53 per barrel in 2005) and the risk of global warming, the European Union (EU) is reinforcing its objectives related to the production of biofuels: they should account for 5.75% of the overall fuel consumption by 2010 in France, as opposed to 1% in 2005. In keeping with the objective set for 2010, the biodiesel derived from rapeseed is still the preferred biofuel (27.5 million hectolitres projected), compared to the ethanol derived from wheat or sugarbeet (9.3 million hectolitres projected). Our model makes it possible to foresee that there will be a competition between food and energy crops by 2006 and that this will occur even before all of the fallow areas are requisitioned. Our... |

| Positive Mathematical Programming (PMP) is one of the most commonly used methods of calibrating activity linear programming (LP) models in agriculture. PMP applications published thus far focus on the estimation of a farm’s nonlinear cost or profit function and rely on the recovery of unobserved or implicit information that can explain the initial model’s inability to calibrate. In this paper we use the PMP procedure to calibrate an expected utility model under the assumption that this implicit information can reveal a farmer’s profit expectations and risk attitude. The perfect calibration shows that PMP can be applied not only to LP models, but also to models that incorporate risk and this provides an interesting alternative to the traditional PMP... |

| Management strategies and performance differ among farmers, as a result of different, multiple and often conflicting goals. Many approaches to building farm level models that incorporate multiple goals have been developed over the years, most of which share a common weakness. The determination of the goals to be used as attributes in the utility function is the result of a highly interactive process with the individual farmer, often difficult to implement. In this study, we use a non-interactive methodology, described in recent literature, to elicit the utility function of selected sheep farmers in western Greece, since farmers often appear reluctant to answer straightforward questions about their goals and preferences. Τhe results indicate that sheep... |
