IMPACT OF THE CAP REFORM ON THE SPANISH AGRICULTURAL SECTOR AgEcon
Judez, Lucinio; de Andres, Rosario; Ibanez, M.; De Miguel, J.M.; Miguel, J.L.; Urzainqui, Elvira.
This paper analyses the impact of the 2003 CAP reform on Spanish agricultural sector in the context of the recent CAP Health Check and high food prices, using PROMAPA, a positive mathematical programming model for representative farms. The analysis compares the model results for base year 2002 to the findings for a scenario with the CAP reform measures in place, taking into account recent modifications. The effect of adopting a full decoupling scheme instead of the present partial decoupling is also studied. Brief descriptions are given of the PROMAPA model, the representative farm considered and the assumptions about both price variations and the policy measures simulated. The findings showed that the farming area for cereals grew substantially after...

A METHOD FOR INCLUDING IN PMP MODELS ACTIVITIES NON-EXISTENT IN THE BASELINE SITUATION AgEcon
Judez, Lucinio; de Andres, Rosario; Ibanez, M.; Urzainqui, Elvira.
When working with positive mathematical programming (PMP) models it is generally admitted that it is not possible to consider in the modeled unit activities that are not present in the baseline situation of the unit. This constitutes a considerable drawback for traditional PMP techniques which cannot be applied in specific cases, in particular to the study of the impact of new agri-environmental programs that subsidize crops grown with technologies different to those applied in the baseline situation. This paper presents a method for dealing with these cases, which can be easily implemented as an extension of the traditional calibration techniques of PMP. The method is applied to a specific problem, using modified calibration expressions derived from...

Single payment scheme and dual values of land in PMP models AgEcon
Judez, Lucinio; de Andres, Rosario; Urzainqui, Elvira.
Land dual values are one of the important aspects of the results of mathematical programming models used to evaluate the impact of agricultural policy measures at regional and farm level. When the decoupling of direct payments and the payment entitlements per hectare are included in PMP models in the context of the Single Payment Scheme (SPS), the analysis of the land dual values is more complex than in models which do not take these aspects into account. In this paper, we present a theoretical analysis of the land dual values when the SPS is included in PMP farm models. This theoretical analysis is carried out for the base year (linear model) and for a simulated year (quadratic model).The results of this analysis are illustrated by comparing numerically...
