Do economics journal archives promote replicable research?
All the long-standing archives at economics journals do not facilitate the reproduction of published results. The data-only archives at Journal of Business and Economic Statistics and Economic Journal fail in part because most authors do not contribute data. Results published in the FRB St. Louis Review can rarely be reproduced using the data+code in the journal archive. Recently created archives at top journals should avoid the mistakes of their predecessors. We categorize reasons for archives' failures and identify successful policies.
