Frequently asked questions (FAQ) about ReplicationWiki usage. If your question is not answered here, then please ask for help: Jan H. Höffler [1]


About the project

For scientific progress, it is pivotal to control research findings by independently replicating results, thus making the findings more reliable. However, in empirical econometric research, this is not yet common practice or at least the findings are often not disseminated. By teaching replication to students, we plan to replicate a large number of studies. This process will raise awareness for the need of 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.

The project Replication in Economics was started at the Chair of Statistics at Georg-August-Universität Göttingen by Prof. Dr. Thomas Kneib, Jan H. Höffler and several student assistants. You find a list of the first contributors here. They form the initial team of administrators and bureaucrats.

In the wiki we inform about published replications and about the availability of replication material for empirical studies in the social sciences. Also we replicate empirical studies in seminars with students. We already cooperated with the University of Toronto, Canada, University of Bonn, Germany, the MAGKS interuniversity doctoral program in economics supported by the universities of Marburg, Aachen, Gießen, Göttingen, Kassel and Siegen, Germany, the Graduate Institute in Geneva, Switzerland, and Nanjing Agricultural University, China. It has been endorsed by the American Economic Association, the UK Economics Network, and the Academy for Sociology. We welcome everyone else interested in joining the project.

Who can contribute to the replication project?

At the moment, access to writing rights is restricted to researchers and journalists. Students can edit discussion pages. In order to maintain usage of real names it is necessary to register your user account, e.g. using an institutional mail address. More information on Help:Account

Who is funding the project?

In its starting phase this project was funded by the Institute for New Economic Thinking (INET): Replication in Empirical Economics (INET Grant).

How can I contribute to the wiki?

You can join the project by entering information on new replications or on empirical articles. You can also improve the articles in the wiki and make comments on discussion pages. You can make recommendations how to improve the wiki or find open tasks here. You can publish your replication in the working paper series of the project. For more information please contact Jan H. Höffler.

How do I use the wiki?

With few exceptions, pages for empirical studies can be edited with forms. This way no knowledge of the wiki markup language is needed. Users who already have experience with other wikis can use the same commands. For all others, there is a small collection of basic commands at Help:Editing.

How can I enter a new empirical study?

Please refer to Help:New Article.

How can I enter a new replication?

This is explained on the page Help:New Replication.

How can I enter a new journal?

Please refer to Help:New Journal.

Where and how can I discuss wiki pages?

Every page of an article or a replication has its own discussion page. You can find it on the very top left of the page. For further information please refer to Help:Discussion Pages.

How can I find a replication?

You can find all replications in alphabetical order by browsing in the category replication. The full-text search can be found on the upper right of each page. More detailed instructions at Help:Search.

Is the journal of the empirical study or replication already entered?

You can find all the entered journals in alphabetical order in the journal acronym directory.

I search an article to replicate

In the wiki you can find a lot of articles lacking replication. In order to find out which empirical studies are regarded most relevant to be replicated each user can cast a vote on each study. Here you find a ranking of the studies that are regarded most relevant to be replicated. See also: Help:Search.

How reliable is the information in the replication wiki?

The information for the first version of the wiki was mainly compiled by students. Much is missing and there are most probably many errors. It has however already proven to be quite useful when searching for studies to be replicated in university courses. Wrong or missing information can be corrected or added by registered users who are able to make changes. You can check in the history who edited the information and look up if there are different opinions on the discussion page to make your judgment on reliability of each entry.

I found an error in a wiki article

All registered users can edit articles and are welcome to improve the wiki. Moreover, each article has its own discussion page to ask questions or make constructive comments regarding its content. When you are viewing the article, just click on the discussion tab at the top of the page.
