Abstract

Currently, policy decisions are often made based on untested scientific results. Replication studies repeat previously published research and, thus, are an effective way to test the validity and reliability of research studies, as well as to test the potential for generalisations of such studies. Replications can contribute to improved policy decisions and thus more efficient use of resources. To date, very few replications of research in agricultural economics are available and the incentives to engage in replications are low. Moreover, the conditions for replicating studies are poor. For example, published articles often lack full transparency in terms of documentation, data and computer code. This Point de Vue highlights the advantages of striving for conditions that facilitate replication studies and foster such a culture in agricultural economics. Policymakers could explicitly invite and support replications of studies that are key for good policymaking. To this end, they can address both demand‐side and supply‐side problems of replications, for example, by inviting, valuing and supporting replications of policy‐relevant analyses and by providing institutional and legal infrastructure facilitating open science and replications. With this, policy can support the agricultural economics profession, while agricultural economists can support sound policymaking, both reaping the benefits of a more transparent research culture. Actuellement, les décisions en matière de politique sont souvent prises sur la base de résultats scientifiques non testés. Les études de réplication reprennent des recherches déjà publiées et constituent donc un moyen efficace de tester la validité et la fiabilité des études de recherche, ainsi que leur potentiel de généralisation. Les réplications peuvent contribuer à de meilleures décisions en matière de politique et, par conséquent, à une utilisation plus efficace des ressources. À ce jour, il n'existe que très peu de réplications de recherches en économie agricole et les incitations à s'engager dans des réplications sont faibles. De plus, les conditions de réplication des études sont médiocres. Par exemple, les articles publiés manquent souvent de transparence totale en termes de documentation, de données et de code informatique. Ce Point de Vue met en évidence les avantages de rechercher des conditions qui facilitent les études de réplication et favorisent une telle culture en économie agricole. Les décideurs de l'action publique pourraient explicitement inviter et soutenir la réplication d’études qui sont essentielles à une bonne élaboration des politiques. À cette fin, ils peuvent résoudre les problèmes de réplication à la fois du côté de la demande et de l'offre, par exemple en invitant, en valorisant et en soutenant la réplication d'analyses pertinentes pour les politiques et en fournissant une infrastructure institutionnelle et juridique facilitant la science ouverte et les réplications. Ainsi, les politiques peuvent soutenir la profession d’économiste agricole, tandis que les économistes agricoles peuvent soutenir l’élaboration de politiques judicieuses, tous deux récoltant les bénéfices d'une culture de recherche plus transparente. Derzeit werden politische Entscheidungen häufig auf der Grundlage nicht überprüfter wissenschaftlicher Ergebnisse getroffen. Replikationsstudien wiederholen bereits veröffentlichte Forschungsergebnisse und sind daher ein wirksames Mittel, um die Gültigkeit und Zuverlässigkeit von Forschungsstudien zu testen und das Potenzial für Verallgemeinerungen solcher Studien zu bewerten. Replikationsstudien können zu besseren politischen Entscheidungen und somit zu einer effizienteren Nutzung von Ressourcen beitragen. Bislang gibt es nur sehr wenige Replikationen von agrarökonomischen Forschungsergebnissen, und die Anreize für diese Arte von Studien sind gering. Außerdem sind die Bedingungen für die Wiederholung von Studien schwierig: Es fehlt den veröffentlichten Beiträgen oft an vollständiger Transparenz in Bezug auf Dokumentation, Daten und Programmcode. Dieser Point de Vue zeigt die Vorteile auf, die sich aus verbesserten Rahmenbedingungen für die Durchführung von Replikationsstudien ergeben und eine solche Praxis in der Agrarökonomie fördern. Politische Entscheidungsträgerinnen und ‐träger könnten gezielt zu Replikationsstudien ‐ die für eine gute Politikgestaltung entscheidend wären ‐ auffordern und diese unterstützen. Zu diesem Zweck können sie sowohl nachfrage‐ als auch angebotsseitige Probleme mit Replikationsstudien angehen, indem sie diese beispielsweise nachfragen, wertschätzen und unterstützen. Zudem können sie eine institutionelle und rechtliche Infrastruktur bereitstellen, die offene Wissenschaft und Replikationen erleichtert. Auf diese Weise kann die Politik den Berufsstand der Agrarökonominnen und Agrarökonomen stärken, während sie eine solide politische Entscheidungsfindung begleiten können. Beide Seiten würden von einer transparenteren Forschungskultur profitieren.
