Production Effects of Direct Payments to Active Farmers: a Microeconomic Dynamic and Stochastic Analysis AgEcon
Carpentier, Alain; Gohin, Alexandre; Heinzel, Christoph.
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...

Accounting for agronomic rotations in crop production: A theoretical investigation and an empirical modeling framework AgEcon
Carpentier, Alain; Gohin, Alexandre; Letort, Elodie.
As far as crop acreage choices are concerned, a consensus seems to exist among agricultural scientists and extension agents: crop rotation effects and the related constraints are major determinants of farmers’ crop choices. Crop rotation effects are inherently dynamic. They are generally ignored in multicrop models with land as an allocable input found in the literature since most of these models are developed within a static framework. The aim of this paper is twofold (i) to propose a new approach and tools for investigating dynamic crop acreage choices accounting for crop rotation benefits and constraints and (ii) to illustrate the impacts of crop rotation effects and constraints on farmers’ acreage choices through simulation examples. The models...

The decoupling of farm programs: Revisiting the wealth effect AgEcon
Femenia, Fabienne; Gohin, Alexandre; Carpentier, Alain.
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...

Measuring farmers’ risk aversion: the unknown properties of the value function AgEcon
Cao, Ruixuan; Carpentier, Alain; Gohin, Alexandre.
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...

Modelling acreage decisions within the multinomial logit framework : profit functions and discrete choice models AgEcon
Carpentier, Alain; Letort, Elodie.
The first purpose of this paper is to propose theoretical justifications for using Logit acreage share models. Two approaches are presented: the Logit shares can be derived from a well defined profit function or derived as the result of a set of discrete choices. It is next shown that both theoretical frameworks allow to define generalizations of the standard Logit shares. These generalizations build on developments of the Multinomial Logit framework for modelling discrete choices and seek to define models that are flexible and empirically tractable. Two applications are presented to illustrate the empirical interest of the proposed models. Both use a rotating panel of French farms (1987-2006) and consider the estimation of yield functions, variable input...

WILLINGNESS TO PAY FOR AN INCREASE IN THE QUALITY OF DRINKING WATER: AN APPLICATION TO FRANCE AgEcon
Carpentier, Alain; Vermersch, Dominique.
In this paper a method to infer the value for consumers of the quality of supplied water is presented and applied. It uses concepts developed in the literature of environmental good valuation and the literature of equivalence scale measurement. It is applied to French data.

Variable Input Allocation: Why Heterogeneity Matters? AgEcon
Letort, Elodie; Carpentier, Alain.
The allocation of variable inputs among crops is a common problem in applied studies that use farm accountancy data. Standard farm accounting information is typically restricted to aggregate or whole-farm input expenditures; there are usually no details on how these expenditures are split among crops. Most studies employing multi-crop econometric models with land as an allocable fixed input consider generally variable input uses at the farm level (Moore and Negri, 1992). However, the allocation of variable inputs among crops appears to be useful for several objectives, such as to analyze the evolution of gross margins at the crop level, to investigate the empirical validity of a multi-crop econometric model and to provide important information for...
