Viewpoint: Replication in economics
نویسندگان
چکیده
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. JEL classification: B41, A14, C59 Réplication en science économique. L’examen du rôle potentiel de la réplication en science économique souligne la pauvreté à la fois de la réplication pure (la vérification des résultats des textes publiés en utilisant les données utilisées dans ces travaux) et de la réplication scientifique (l’utilisation de données tirées de populations différentes pour valider des résultats). Plusieurs controverses en économie empirique sont utilisées pour illustrer comment se comporter et ne pas se comporter dans la réplication des travaux d’autrui. Les incitations à faire de la réplication sont analysées, et certaines suggestions sont faites aux rédacteurs de revues et aux auteurs afin de stimuler une activité plus grande dans ce registre – que les économistes applaudissent mais que bien peu acceptent de pratiquer.

Macroeconomics from the Viewpoint of Modern Institutional Economics
Both Keynesians and modern institutional economists are critical of the “classical economists”. In being so, they employ similar micro foundations of the business behavior (the “institutional arrangements”) of individuals.

We consider that it is very essential to base economics theory on measurable quantity from the beginning, because optimization at individual and aggregate levels is the very hallmark of modern economics theory (Tubaro, 2006, p.1 [3]). That measurable quantity can be observed by virtue of experiment or field observation. Indeed, we think that such an experimental approach is new and original in ...
