Trade preferences for developing countries: A survey of results
综述了发达国家对发展中国家主要优惠贸易安排的实证研究，发现这些安排通常促进贸易并改善捐赠国福利，但对发展中国家总出口影响有限，且未提供关于幼稚产业保护或经济多样化的证据。
Empirical studies of the trade and development effects of the major preferential trading schemes between the industrialised countries and the developing countries are surveyed. Most studies find the agreements to be trade creating, improving welfare for the donor, though general equilibrium analysis indicates that terms‐of‐trade deterioration offsets efficiency gains. There is some evidence that trade preferences stimulate LDC exports of preferred products, but total exports are not significantly affected due to limited product coverage. The existing literature does not provide evidence on the degree of infant industry protection or on economic diversification of the beneficiaries.
