This article summarizes what we know about marketplaces in the United States, relates that knowledge to a research agenda on the subject, and makes suggestions for planning practice. This review accomplishes these three goals beginning with a historical review of marketplaces, focused mostly on the United States. The research literature on marketplaces is reviewed from political, economic, social, and health perspectives with suggestions for further basic and applied research. In short, the article shows how marketplaces were once tools of nascent planning and public policy, describes the reasons they should be again, and shows how planners and policy makers can advance public purposes through markets.
