New paper published: “Open access to research data: Strategic delay and the ambiguous welfare effects of mandatory data disclosure”

Frank Mueller-Langer and Patrick Andreoli-Versbach have published a new research paper on ‘Strategic delay and the ambiguous welfare effects of mandatory data disclosure’.

In the abstract of the paper, the researchers state:

Mandatory disclosure of research data is an essential feature for credible empirical work but comes at a cost: First, authors might invest less in data generation if they are not the full residual claimants of their data after the first journal publication. Second, authors might “strategically delay” the time of submission of papers in order to fully exploit their data in subsequent research. We analyze a three-stage model of publication and data disclosure. We find that the welfare effects of universal mandatory data disclosure are ambiguous. The mere implementation of mandatory data disclosure policies may be welfare-reducing, unless accompanied by appropriate incentives which deter strategic delay.

American Economic Review publishes AEA’s Session Papers on Replication

Two weeks ago, the American Economic Review published the ‘Papers and Proceedings‘ of the 129th annual meeting of the American Economic Association (AEA) held in January, 2017.

At this year’s meeting, one session was dedicated to the topic of ‘Replication in Microeconomics‘ while another focussed on ‘Replication and Ethics in Economics: Thirty Years after Dewald, Thursby, and Anderson“.

In both sessions, very interesting and excellent papers were presented.

Below, I list all presentations of these sessions and the corresponding links to the papers (if available): Read the rest of this entry »

New Working Paper published: ‘The Economics of Replication’

Frank Mueller-Langer, Benedikt Fecher, Dietmar Harhoff and Gert G. Wagner have published a new working paper on the ‘economics of replication’.

In the abstract of the paper, the researchers state:

“Replication studies are considered a hallmark of good scientific practice. Yet they are treated among researchers as an ideal to be professed but not practiced. To provide incentives and favorable boundary conditions for replication practice, the main stakeholders need to be aware of what drives replication. Here we investigate how often replication studies are published in empirical economics and what types of journal articles are replicated. We find that from 1974 to 2014 less than 0.1% of publications in the top-50 economics journals were replications. We do not find empirical support that mandatory data disclosure policies or the availability of data or code have a significant effect on the incidence of replication. The mere provision of data repositories may be ineffective, unless accompanied by appropriate incentives. However, we find that higher-impact articles and articles by authors from leading institutions are more likely to be subject of published replication studies whereas the replication probability is lower for articles published in higher-ranked journals.”

The paper is available here.

New Working Paper: “Perceptions and Practices of Replication by Social and Behavioral Scientists”

One of our project partners has just released a publication that deals with the replication crises in economics and the social sciences.

In the abstract the three autors state:

We live in a time of increasing publication rates and specialization of scientific disciplines. More and more, the research community is facing the challenge of assuring the quality of research and maintaining trust in the scientific enterprise. Replication studies are necessary to detect erroneous research. Thus, the replicability of research is considered a hallmark of good scientific practice and it has lately become a key concern for research communities and science policy makers alike.

In their discussion paper Fecher, Fräßdorf and Wagner analyze perceptions and practices regarding replication studies in the social and behavioral sciences. Their analyses are based on a survey of almost 300 researchers.

EDaWaX: New research paper published

We are happpy to announce that our new peer-reviewed research paper “Data Policies and Data Archives: A New Paradigm for Academic Publishing in Economic Sciences?” has just been published in the Conference Proceedings of the 19th International Conference on Electronic Publishing (ELPUB15). The paper summarises some results of a broader analyses on data policies of journals in economics and business studies.

In our paper we summarise the findings of an empirical study in which a sample of 346 journals in economics and business studies were examined. We regard both the extent and the quality of journals’ data policies, which should facilitate replications of published empirical research. The paper presents some characteristics of journals equipped with data policies and gives some recommendations for suitable data policies in economics and business sciences journals. In addition, we also evaluate the journals’ data archives to roughly estimate whether these journals really enforce data availability. Our key finding is that we are currently not able to determine a new publishing paradigm for journals in economic sciences.

I would like to thank the reviewers and the organisers of the conference for their useful comments! The full paper is available here.

EDaWaX: State of affairs

As you might have noticed, currently I don’t have much time to publish new articles on the blog. The reason is that our project is currently publishing a lot of the results we achieved in the course of the last two years.

One of these publications has been published yesterday – it is a nice summary of the project’s main results, but still not all of them. The paper “Replizierbare Forschung in den Wirtschaftswissenschaften erhöhen – Eine Herausforderung für wissenschaftliche Infrastrukturdienstleister” is available online.

Data Sharing: Poor Status Quo in Economics #Update

In the context of our research project EDaWaX a new research paper has been published by Patrick Andreoli-Versbach (International Max Planck Research School for Competition and Innovation (IMPRS-CI), LMU Munich, Munich Center for Innovation and Entrepreneurship Research (MCIER)) and Frank Mueller-Langer (Max Planck Institute for Intellectual Property and Competition Law, IMPRS-CI, MCIER).

The paper analyzes the data sharing behavior of 488 randomly chosen empirical economists. More specifically, the researchers under study were chosen uniformly across the top 100 economics departments and the top 50 business schools and randomly within the respective institution. Economics departments were chosen using the Shanghai Ranking 2011 in Economics and Business and business schools were chosen using the Financial Times Global MBA Ranking 2011.

EDaWaX: First paper published! #Update

I am happy to announce that some of the results we obtained in our analyses have been published in the proceedings of the WissKom2012 conference (pp.29 ff).

In the research paper for Wisskom2012 Olaf Siegert and I summarized some of the findings of the EDaWaX project.  Unfortunately the paper is available in German only, but I promise to publish some more of our major findings in English – eighter on this blog or in a seperate paper. Some results of our analyses are already published here: ( |1 | 2 | 3 | 4 | )

The presentation I gave in Jülich is available in the download section of the blog.

I also wrote a paper in English that has already been accepted by a peer-reviewed journal. I hope to find time to rework the article and to integrate the very helpful notes and comments of the reviewers anytime soon.

I’ll come back to you, when I’ve got news.

# Update 2012-11-14 #

A slightly updated version of the paper is also available now. It has been published in Working Paper Series of the German Data Forum (RatSWD), No. 210. The RatSWD Working Papers series was launched at the end of 2007. Since 2009, the series has been publishing exclusively conceptual and historical works dealing with the organization of the German statistical infrastructure and research infrastructure in the social, behavioral, and economic sciences.

EDaWaX-Project wins LIBER Award for Library Innovation 2012

At the end of last week I received an E-Mail from the LIBER Executive Director that congratulates our project for winning the LIBER Award for Library Innovation 2012! These are really great news!

Our abstract:  “Data Management in Scholarly Journals and Possible Roles for Libraries – Some Insights from EDaWaX” was among the top three papers that were submitted to the conference.
