This project provided new policy research capacity for the government of Costa Rica, including a Costa Rican Social Accounting Matrix (SAM) and the CGE model developed collaboratively by the OECD Development Centre and MIDEPLAN. Together, this integrated economywide database and model represent new capacity for policy analysis in Costa Rica. While SAMs and other economic models have been built for this country in the past, none are so up-to-date, detailed, and based on state-of-the-art methodology as the research products described below. In the hands of trained investigators, this modeling facility can provide analytical support for a wide variety of economic policy work, including trade, public finance, industry policy, and agricultural policy.
