Viewpoint: Replication in economics


  • Daniel S. Hamermesh


This examination of the role and potential for replication in economics points out the paucity of both pure replication - checking on others' published papers using their data - and scientific replication - using data representing different populations in one's own work or in a comment. Several controversies in empirical economics are used to illustrate how and how not to behave when replicating others' work. The incentives for replication are examined, and proposals aimed at journal editors and authors are advanced that might stimulate an activity that most economists applaud but few perform.
