In this study, the authors report on the status of comparative economics systems in the U.S. undergraduate economics curriculum. The treatment of comparative economics systems topics in introductory courses is examined through a survey of standard textbooks. To evaluate comparative economics systems at the advanced undergraduate level, they rely on survey data, searches of course catalogs, and an evaluation of available textbooks. They find course offerings in comparative economics systems have declined noticeably in the past ten years, with departments shifting to courses that study the economics of specific regions or countries.
