This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the effort effect working against giving preferences and the selection effect working for them. When education is costly and easy to obtain (as in the U.S.),...

This paper compares the effects of migration restrictions using licenses which are freely traded in a competitive labor market to those that occur when licenses are allocated to firms who are not permitted to trade them. There is reason to expect that a policy of making licenses non-transferable...

This paper provides definitions and measures of the extent of adaptability of an economy to exogenous changes in product prices, factor availability and technological change. It is argued that flexibility can in general only be defined relative to the exogenous changes that occur. Using a dual...

Available estimates of tariff equivalents of quotas and welfare calculations on the costs of MFA quotas for developing countries are based on the premise of perfect competition in both product and license markets. It is also assumed that the exporting countries which administer the MFA quotas...

This paper studies competition between a small number of suppliers and a single buyer (or an auction with a small number of bidders and a single seller), when total demand (supply) is uncertain. It is well known that when a small number of suppliers compete in supply functions the service is not...

This paper asks whether the results obtained from using the standard approach to testing the influential Grossman and Helpman %u201Cprotection for sale (PFS)%u201D model of political economy might arise from a simpler setting. A model of imports and quotas with protection occurring in response...

We develop a new model of quality to capture the idea that even if a customer chooses to purchase a product, it may fail to deliver.' In this event, the customer may wish to choose some other product. We model this as a two stage game where firms first choose quality and then price. We find that...

The market access and welfare effects of Free Trade Areas (FTAs) without Rules of Origin (ROOs) are studied. We consider both the final and intermediate goods markets and their interlinkage. The FTA weakly reduces all tariffs and prices within the FTA. This raises quantity demanded and reduces...

This paper analyzes the role of network externalities and expectations about them in the formulation of trade policy. Their effects are studied in duopoly situations when products are compatible and when they are incompatible and when multimarket effects are possible. Network externalities and...

Recent work in optimal trade policy for imperfectly competitive markets usually identifies the optimal level of an instrument, and when more instruments are allowed, general interpretations have been unavailable, This paper analyzes the jointly optimal levels of a Variety of instruments with...
