摘要：Empirical evidence on the Generalized System of Preferences (GSP) for low-income countriesgenerally portrays a rather stark prediction: the program has produced virtually no impacton intended low-income beneficiaries’ exports to high-income countries. This result, based ontotal merchandise trade, is misleading because it masks three underlying heterogeneities in theprogram: i) preference structure across countries, ii) pre-existing distortions across sectors, andiii) rules of origin. Using a theoretically consistent gravity equation for sector- and product-leveltrade over 1962–2010, we illustrate that the GSP has delivered significant positive effects for lowincomecountries’ agricultural exports (but not necessarily for their nonagricultural exports) todeveloped countries.
