Understanding the World Economy is provided by Nouriel Roubini, Associate Professor of Economics and International Business at the Stern School of Business, New York University for his MBA Macroeconomics course. The aim of the course is to review and analyze current macroeconomic issues from the viewpoint of businesses and policymakers. The highlight of the web site is the collection of lecture notes by Nouriel Roubini and David Backus covering topics on the macroeconomy. These notes are comprehensive and contain links to other web resources related to the topics. The other highlight of the site is "Recent Macroeconomic Controversies and Policy Debates," which introduces the readers to the major macroeconomic issues in the United States. The topics covered there include supply-side economics, productivity growth and NAIRU (Non-Accelerating Inflation Rate of Unemployment) among others. A hypertext glossary of business cycle indicators and links to sources of data for business cycles can be found on the site as well. Finally, the site also contains the syllabus, reading list, handouts and assignments for the course.
