Summary
The use of the economic surplus measures has been widespread in the welfare evaluation of trade distortions in agricultural markets. However, the criterion based on the sum of surplus areas can be ambiguous since it usually involves the implicit acceptance of a restrictive class of value-judgements. This article approaches the evaluation of the Spanish agricultural prices policy by means of Atkinson's welfare function, that makes clear the trade-off between efficiency and equity, and explicitly includes the policy-maker's inequality aversion. Optimum levels of protection are estimated at various inequality-aversion levels.
