We constructed a wiki website for replication in economics: http://replication.uni-goettingen.de

It serves as a database of empirical studies, the availability of replication material for them and of replication studies. It can help for research as well as for teaching replication to students. We taught seminars at several faculties internationally for which the information of this database was used. In the starting phase the focus was on some leading journals in economics. We now cover more than 2000 empirical studies and so far 172 replications. One can search for software, methods, data types, and datasets used, as well as for JEL codes. So far 17 studies are listed as using Mathematica, and most of them have data and code for replication in the journal archive. For MATLAB there are 260 studies, for Stata 860, and of these 629 with data and code in the journal archive and 5 with code elsewhere online. I consider it quite likely that we list more studies for which Mathematica was used and we just have not detected it.

Could you add studies for which you know Mathematica replication files are available online? Could you add studies that you tried to replicate or that you authored yourself? It is a wiki, so everyone can participate and contribute. Replication results can be published as replication working papers of the interdisciplinary University of Göttingen's Centre for Statistics. The website also has an option to vote which studies should be replicated – votes are anonymous. Teaching and providing access to information will raise awareness for the need for replications, provide a basis for research about the reasons why replications so often fail and how this can be changed, and educate future generations of economists about how to make research replicable. Please take a look at our website and register. You are also welcome to give feedback!

Do you know any economists whom you could tell about our project? Could you add any replications you know? They would then automatically be featured as latest replications on the main page until five other publications are added, so they would get more attention - so far we had more than 310,000 page views. The American Economic Association already added our website to their collection of useful resources for economists. IDEAS/RePEc links back to pages in the wiki that have a link to RePEc. This page for a study with Mathematica is an example. (click on lists to see the link back to ReplicationWiki)

If you teach, please inform your students about the project or colleagues who include replication in their teaching or who may want to add their empirical studies.

In 2014, the work was presented at the Research Transparency Forum of the Berkeley Initiative for Transparency in the Social Sciences, the conference of the European Economic Association and the Econometric Society in Toulouse and at the Annual Meeting of the American Economic Association in Boston. It will next be discussed at the 2015 National Conference on Teaching and Research in Economic Education (CTREE), Minneapolis, USA, May 27-29, 2015. I would be glad to meet whoever is interested. Please don't hesitate to forward this message or parts of it and we will be glad to answer any questions you or others may have.
