Top scholars synthesize and analyze scholarship on this widely used tool of policy analysis in 27 articles, setting forth its accomplishments, difficulties, and means of implementation. Though CGE modeling does not play a prominent role in top U.S. graduate schools, it is employed universally in the development of economic policy. This collection is particularly important because it presents a history of modeling applications and examines competing points of view.

• Presents coherent summaries of CGE theories that inform major model types
• Covers the construction of CGE databases, model solving, and computer-assisted interpretation of results
• Shows how CGE modeling has made a contribution to economic policy
