摘要：The debate over the “right way” of protecting geographical indicators (GIs) has resulted in a growing body of literature investigating the welfare effects of GI policies using economic modelling approaches. This paper presents a synthesis of a small yet growing number of analytical studies on GIs. We find that modelling results and related policy conclusions hinge on different assumptions regarding consumer preferences, quality differentiation and weights attributed to producer or consumer welfare measures. Inconclusive results regarding a pareto-optimal design of GI policy leave several unresolved issues to researchers and policy makers assigned with the welfare implications of GI-based market interventions.
