A Structural Model for Evaluating the Sector-specific Impacts of Preferential Trade Agreements

This paper develops and estimates a structural model of imperfect competition in international markets. The model incorporates a flexible non-linear demand framework with structural price equations. A general Conjectural Variation approach is developed to characterize strategic interaction. This allows the simultaneous evaluation of the sector-specific terms of trade effects of a Preferential Trade Agreement (PTA), and the extent of international competition in the sector under consideration. The model is then used to evaluate the impact of the Lebanese–Egyptian PTA on the iron and steel import sector in Lebanon. Results confirm the need for a structural approach in the empirical assessment of PTAs.

Determinants of Adoption of Protected Designation of Origin Label: Evidence from the French Brie Cheese Industry

This paper investigates empirically the determinants of agro‐food firms’ adoption of the Protected Designation of Origin (PDO) label. A unique dataset containing firm‐level cost and production information on the French Brie cheese is used, covering the period 1980–2000. The Brie cheese data are especially relevant as PDO Brie producers have coexisted with other non‐PDO producers since 1981. To evaluate the producers’ incentive to opt for PDO certification, we use a structural switching regression model which incorporates cost and production structure variables. Results show that PDO certification is less attractive the higher the costs of raw materials and the greater the size of the company. PDO Brie cheese production costs are estimated to be on average 40% higher than those for non‐PDO Brie. The PDO production process could be technically inefficient when compared with the unconstrained non‐PDO manufacturing; yet, PDO producers benefit from a price premium on their product which offsets their higher production cost.
