This project, sponsored by the Macroeconomics and Growth Division of the Policy Research Department of the World Bank, and the International Center for Economic Growth (San Francisco) examines "the relationship between national policies and economic growth." It offers two basic resources: abstracts and especially data from articles, including a special issue of the Journal of Monetary Economics (Dec. 1993) on this subject), and abstracts on World Bank working papers on the same subject.
