Exporting,Technical Efficiency and Product Quality: An Empirical Analysis of the Agricultural Sector in the Mediterranean Countries

This paper investigates the association between exporting and agricultural performance in terms of production efficiency and product quality. We test for the learning-by-exporting and self selection effects in a panel of advanced and developing Mediterranean countries involved in global market liberalisation. Product quality measures are inferred from trade data using a discrete choice demand model, and technical efficiency scores are appraised using a stochastic production frontier approach. Based on joint estimation of the performance equations and a dynamic export probit decision, the empirical results lend strong support to the self-selection hypothesis. Exporting appears to help quality upgrading that encourages more efficient use of resources.
