Assessing the influence of direct payments on the rental value of agricultural land

Abstract

Economic theory suggests that coupled and decoupled direct payments have different impacts on agricultural rental values because of the different production responses associated with these payments. This study investigates the impact of both coupled and decoupled EU CAP direct payments on rental values in Northern Ireland, using panel data taken from the farm business survey for the period from 1994 to 2002. Theoretically, agricultural land rents are a function of expected market returns and expected associated direct payments. The unobservable nature of expected returns means that actual market returns must be used as a proxy for the former in the empirical specification. As a consequence, the problem of bias due to expectation error arises. Using a GMM technique to take account of this problem, the results of this study show that the impact of CAP direct payments on rental values depends on the type of payment and on the nature of the production characteristics of the associated agricultural commodity.
