This paper provides a general framework for measuring farm support when both price and quantity policy instruments are used jointly. It is based on duality theory in production, i.e., on profit functions corresponding to different (dis-)equilibrium situations. Total Support is decomposed into a...

This paper proposes an analytical framework allowing estimation of the effects of the new instrumentation of the CAP in the arable crop sector--price cuts, compensatory payments and land set-aside schemes--on crop acreage allocations, supplies and yields. Duality theory is used to model crop...

This note shows, using a general equilibrium framework, that the level of utility attainable under a quota-cum-tariff policy is higher than in the tariff-alone case but, as should be expected, lower than without any price distortion. Copyright 1994 by Oxford University Press.
