摘要：Since a seminal work by Armington (1969), estimating source-differentiated import demand has become a useful tool in applied international trade research. Trade policy evaluation and simulation require reliable estimates of the responsiveness of import demand to international price changes. Unfortunately, for certain commodities, reliable estimation of import demand is a particularly arduous task given the pervasive presence of quantitative restrictions in international trade. Import quotas, for example, have been implemented in many countries for a variety of products. In spite of its apparent importance to trade policy analysis, surprisingly little attention has been paid to investigate the impact of an import quota on the estimation of import demand. One exception is the work by Bertola and Faini (1991). They applied the theory of rationing of Neary and Roberts (1980) to investigate the impact of an import quota on the import demand for commodities under quota and non-quota regimes. Similar to the work on demand and production theory under rationing, their results allow one to predict non-rationed import behavior from observations on a market under import rationing. Such results are particularly useful for investigating the effect of complete trade liberalization. To further research on this important, but neglected topic, we consider a different case where an aggregate import quota is applied to a seemingly homogenous product differentiated by country of origin.
