| For the 2014-2020 phase of the Common Agricultural Policy, the European Commission has the opportunity to reduce the leakage of public support to landowners and to better target it towards active farmers. Our purpose is to assess whether shifting the basis of direct payments from land towards active farmers will significantly alter agricultural production decisions. In a dynamic and stochastic microeconomic framework, we identify the impact of this shift on the farm household’s production and consumption decisions. In the dynamic setting the production impacts of direct payments are much higher than previously quantified, because the “long run” absolute risk aversion (associated with the value function) is lower than the “short run” one (associated with... |

| The European Union decided in June 2003 a new reform of its farm policy with a new step toward the decoupling of farm income support instruments. Available impact studies find that this reform will reduce production incentives, substantially for beef and to a lesser extent for arable crops. All these studies assume that the Agenda 2000 arable crop direct payments are already mostly decoupled while beef premiums are much more linked to production. Our main objective in this paper is to test the sensitivity of these results to this questionable modelling of Agenda 2000 direct payments which neglects eligibility rules and land market imperfections. Our analysis reveals that the negative effects of the reform on both arable crop and beef production are not... |

| Recent reforms of agricultural policies in developed countries introduced direct payments to the detriment of traditional production enhancing instruments. Whereas these new instruments can influence production through several effects, current empirical studies do not show any significant impact on production; direct payments mainly increase land values. In this article, we revisit the evaluation of the coupling effects passing through the wealth of agricultural households. The initial wealth of these agents, while being mainly in form of land asset holding, is always assumed to be fixed. On the contrary we show theoretically and empirically that, once the impact of farm programs on initial wealth is properly accounted for, the measure of the coupling... |

| Epizootic outbreaks such as Foot and Mouth Disease are of great concern for agriculture. In this paper, we quantify the potential dynamic impacts of such a disease on Brittany, a French region with a strong livestock sector. We develop a dynamic computable general equilibrium model with rational expectations that allows us to measure the impacts of culling infected animals and restraining movements of live animals on the livestock sectors and downstream food industries. Our results show that economic losses are spread over many periods even with a one-time shock. The impacts on the primary sectors and downstream food sectors do not move in parallel. The food industries suffer most in the first period while the negative impacts on agriculture are mostly... |

| 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. |

| The role played by “speculators” during the 2007/08 food price spike is lively disputed. Our analysis focuses on the increasing participation of index funds in agricultural commodity futures markets before the food price spike. Our central theme is to determine if their prespike massive entry does prepare the subsequent crisis by maintaining low stock levels. We develop a theoretical model explaining the behaviour of speculators and traders on futures and cash markets. We allow index funds to inflict an informational externality on commercial traders that is supposed to induce a lower desire to hold stock. We find out that, once the production decisions of commercial traders are taken into account into the model, the increased net long position of index... |

| The various assessments of the effects of a liberalization of world sugar markets are inconsistent with each other. One cause seems to be the modeling of the EU supply response. We investigate three possible linkages between sugar production under quota and the out-of-quota or "C" sugar supply: i/ the existence of fixed costs covered by the in-quota sugar; ii / the "overshooting" behavior as prevention against poor yields; iii/ the production of C sugar as "reference building" in view of expected reforms. Modeling these effects results in the introduction of an implicit crosssubsidy between in-quota sugar and C sugar. The resulting specification is included in a detailed model of the EU agricultural sector so as to account for intersectoral linkages. We... |

| In relation to the growing debate around multifunctionality, this paper attempts to classify alternative measures of agricultural income support according to their ability in achieving three policy objectives (supporting agricultural income, promoting positive externalities and reducing negative ones) as well as to their induced trade distortion effects. Four income support programs are considered: a production-linked payment program, a land-based payment program and two decoupled payment programs. Their effectiveness as regards to the three policy objectives and their relatives induce trade distortion effects are examined on an equal cost/support basis through a conceptual framework that allows for free entry in the sector and the land price to adjust... |

| We argue in this paper that available econometric estimates of farmers’ risk aversion do not measure true farmers’ preferences towards risky outcomes. Available analyses are mostly of static nature and indeed measure the parameters of the synthetic optimal value function rather than the deep parameters of the utility functions. We derive analytical and empirical results in a simple dynamic and stochastic framework showing that that there is not a simple relationship between utility functions and value functions when agents have many decision variables. In particular we find that the value function does not necessarily exhibit DARA when the instantaneous utility function satisfies DARA and conversely. We recommend performing dynamic econometric estimation... |

| Economic analyses of farm policies generally focus on the long run, steady state impacts while the transition dynamics are often overlooked. In this paper we develop a determinist dynamic computable general equilibrium analysis allowing agents to form imperfect versus pefect expectations. Using an illustrative CAP reform scenario, we simulate an abrupt versus a gradual implementation of this reform. Our results show that if economic agents are able to perfectly anticipate the impacts of the reform, then delaying its implementation is never optimal. On the other hand, if agents gradually learn from market developments, then we find some cases where a gradual implementation of this reform is welfare improving. Such gradual implementation allows minimizing... |
