A Fully Calibrated Generalized CES Programming Model of Agricultural Supply AgEcon
Merel, Pierre R.; Simon, Leo K.; Yi, Fujin.
The use of prior information on supply elasticities to calibrate programming models of agricultural supply has been advocated repeatedly in the recent literature (Heckelei and Britz 2005). Yet, Mérel and Bucaram (2009) have shown that the dual goal of calibrating such models to a reference allocation while replicating an exogenous set of supply elasticities is not always feasible. This article lays out the methodological foundation to exactly calibrate programming models of agricultural supply using generalized CES production functions. We formally derive the necessary and sufficient conditions under which such models can be calibrated to replicate the reference allocation while displaying crop-specific supply responses that are consistent with prior...

About the Efficiency of Input vs. Output Quotas AgEcon
Merel, Pierre R..
Output quotas are known to be more efficient than input quotas in transferring surplus from consumers to producers. Input quotas, by distorting the shadow prices of inputs, lead to inefficient production and generate larger deadweight losses, for a given amount of surplus transferred. Yet, input quotas have been a ubiquitous tool in agricultural policy. Practicality considerations, as well as the difficulty to control outputs that heavily depend on stochastic weather conditions, are arguments that help understand why policy makers may favor input quotas over output quotas. In this paper, we offer an additional explanation that rests on efficiency considerations. Assuming that the regulator only has limited knowledge about the market fundamentals (supply...

Assessing the Opportunity Cost of Growing a Bioenergy Crop in California: a PMP Approach AgEcon
Yi, Fujin; Merel, Pierre R.; Lee, Juhwan; Six, Johan.
A significant increase in demand for fuel ethanol in California should be expected if all gasoline sold in the state were to be blended with 10% ethanol, as envisaged in the State Alternative Fuels Plan. This paper assesses the potential of California agriculture to supply biofuel feedstock in the form of switchgrass. We construct a fully calibrated, multi-region, multi-input and multi-output model of agricultural supply for California’s Central Valley based on the principles of Positive Mathematical Programming. We exploit the biogeochemical model DAYCENT to estimate production functions for switchgrass in each agricultural region. We then predict the extent and location of potential switchgrass production in the Central Valley. Our results suggest that...

Efficiency and Redistribution in the French Comte Cheese Market AgEcon
Merel, Pierre R..
The purpose of this paper is to investigate the economic rationale underlying collective management and supply control mechanisms in European protected designations of origin (PDOs), with a focus on the French Comte cheese market. The argument is based on the presence of imperfect competition at the processing stage of the industry. Assuming that processors are able to exercise both oligopsony power in the procurement of the agricultural output and oligopoly power in the sale of the final product, I show that vertical integration between upstream producers and downstream processors is mutually beneficial as long as the integrated industry is able to exercise some degree of seller market power. I characterize instances where consumers also win from the...

Is There Market Power in the French Comte Cheese Market? AgEcon
Merel, Pierre R..
An NEIO approach is used to measure seller market power in the French Comté cheese market, characterised by government-approved supply control. The estimation is performed on quarterly data at the wholesale stage over the period 1985-2005. Three different elasticity shifters are included in the demand specification, and the supply equation accounts for the existence of the European dairy quota policy. The market power estimate is small and statistically insignificant. Monopoly is rejected, as well as weak forms of Cournot oligopoly. Results appear to be robust to the choice of functional form, and suggest little effect of the supply control scheme on consumer prices.

The Coexistence of GM and non-GM Crops and the Role of Consumer Preferences AgEcon
Merel, Pierre R.; Carter, Colin A..
Crop coexistence is now at the core of the debate on GM technology in Europe. New regulations are being designed in the E.U. in order to "correct" potential production externalities and ensure that conventional and organic production will remain a profitable alternative for farmers. We use a simple Mussa-Rosen type model of preferences to capture the effects of introducing a cost-saving GM crop on incumbent crops, taking explicitly into account consumers' distaste for GM food products. Using a two-technology model, we derive necessary and sufficient conditions for coexistence and show that perfectly competitive farmers with rational expectations will adopt the socially efficient level of GM technology. We also solve a three-technology model to study the...
