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...

Agricultural Supply Response in Fiji AgEcon
Hone, Phillip; Haszler, Henry; Natasiwai, Tevita.
The agricultural sector is a central part of the Fiji Islands economy. Policies to alleviate poverty and stimulate economic growth need to be based on a sound understanding of the local agricultural systems involved. This understanding needs to extend to the responsiveness of production to price changes. To date there have been no published quantitative estimates of the responsiveness of agricultural supply in Fiji to output price changes. In this paper we present a set of highly disaggregated supply elasticities covering many of the major food crops produced and consumed in Fiji. These results have been derived from a stated intention survey of rural households. The results appear consistent with the dual nature of Fiji's agricultural sector and show that...

PMP and Uniqueness of the Calibrating Solution - Revision AgEcon
Paris, Quirino.
This paper demonstrates the existence of a unique solution of the PMP problem when both observed output quantities and limiting input prices are taken as calibrating benchmarks. This version of PMP avoids the use of a user-determined small positive number ε originally introduced for guaranteeing that the dual (shadow) price of binding input constraints be positive. Furthermore, the paper shows how to obtain endogenous output supply and input demand elasticities that match available information about them in the form of previously estimated parameters for an entire region or sector. The framework is applied to a sample of farms also for the case that admits no production for some of the crop activities. The calibrating solution is very close to the observed...
