There is growing concern that much of the empirical research in labor economics and other applied areas may not be reproducible. Correspondingly, recent years have seen an increase in replication studies published in economics journals. Despite this increase, there are many unresolved issues about how replications should be done, and how to interpret their results. Replications have demonstrated a potential for clarifying the reliability and robustness of previous research. Much can be done to encourage more replication research, and to exploit the scientific value of existing replication studies.
Replications can help to confirm that an original study was done correctly.
Replications can be used to determine if the findings of a study generalize to other, similar settings.
Replications have demonstrated their usefulness in assessing the results of previous, high-profile research.
There is no consensus about what a replication is, nor about what constitutes a “successful replication.”
Little is known about how frequently replications occur, or how often they confirm or disconfirm the original studies.
There is no standardized system to collect, categorize, and link replications to the respective original studies.
