This constraints to growth analysis (CA) was prepared by a joint technical team composed of economists from the Government of El Salvador and the Government of the United States. Its purpose is to provide an analytical and empirical foundation for joint efforts to promote broadbased economic growth in El Salvador. These efforts will be undertaken as part of Partnerships for Growth (PfG), an effort by the Obama Administration to foster growth in a select number of countries and seed the next generation of emerging markets. The exercise of analyzing growth restrictions under the Partnerships for Growth has been enriching for both governments, as it has helped to deepen the shared understanding of the problems of economic growth in El Salvador. All four of the countries selected for the Partnerships for Growth undertake a Constraints Analysis following the growth diagnostics methodology developed by Hausmann, Rodrik, and Velasco (HRV). The results of these studies are intended to facilitate planning of a consensus set of near-term public policies agreed to by the partner country and United States governments aimed to improve investment and economic growth.
