Stepping down now, I have been the Data Editor for Management Science for four years and ~1000 replication packages (supported by @MilosFisar, @chrhuber_ and @ozkesali). So here is some look back at trends, mostly in pie charts. 1/17 x.com/bgreiner_tweet…

We have received top-up funding for our meta-reproduction and are looking for a few more replication fellows. We pay 2,500 EUR for reproducing a paper that we assign, using a protocol which we also assign. If you are interested reach out via DM or email.
I studied over 8000 reproduction packages from leading economic journals. The plots show the shares that use Stata, Matlab, Python and R over time. In 2023 R was used in 20% of reproduction packages but Stata remains stable above 70%. More details here skranz.github.io/r/2023/12/29/F…
#EconTwitter Several journals publish selected articles with an open access license (e.g. CC license for the QJE, academic.oup.com/pages/open-res…) Does anybody know a way to list all open access articles for (some) major economic journals? Is there a data base / search option?
Great study and > 95% reproduction rate of the articles with data available seems amazingly good news. This also suggests huge effort and great work by those involved in creating and originally checking the replication packages, in particular by Ben as the MS data editor 👏

I was just asked “how much of the research in management science is actually reproducible?” My response? What a coincidence! I am so glad you asked. I just had a paper on this. It’s 95%, if the data is there. pubsonline.informs.org/doi/10.1287/mn… What did you just got asked?
I was just asked "what is the most common mistake you see teachers and parents making when evaluating children?" My response? They too often assume indolence when the culprit is academic inefficiency. In doing so, they miss a chance to teach optimally. In a recent study,…

@sean_ulm @maurerchr @pleh_mann Gegenüber KapMech könnte ich mir vorstellen, dass das vorerst so günstiger sein könnte als mit H2-Hybridkraftwerken. Aber stimme @maurerchr natürlich in seinen beiden Punkten zu. Und: Saubere Lösung wäre Zonenteilung, damit der Markt lokale Investitionsanreize geben kann.
@sean_ulm @pleh_mann @ingmarschlecht Würde zumindest erwarten, dass es immer teurer wird, StK betriebsbereit zu halten. Die Anlagen altern, die gesamte StK-Logistikkette nur für ReserveKW aufrechtzuerhalten, ist teuer. Und Reserven außerhalb des Marktes sind ja auch eher ineffizient, zumindest wenn sehr groß...
🌟 Shoutout to the >700 volunteers of the Management Science Reproducibility Collaboration who dedicated over 6,500 hours to this study. Your commitment to enhancing scientific reliability is commendable! 👏
@maurerchr @sean_ulm Genau. Grundlegend gibt es hier wohl zwei Möglichkeiten: Entweder man trennt Hedge und Förderung in separate Instrumente (letzteres ggf. über eine fixe Marktprämie). Oder Förderung direkt via fCfD, dann brauchts Vorgaben über maximale Vertragsmenge -> Anreize daraus beachten.
@sean_ulm @ingmarschlecht Das ist in der Tat eine schwierige Frage, an der wir selbst noch basteln und wo es irgendwann demnächst auch noch mal ein Update gibt. Wir hatten zunächst va den Hedge Charakter im Blick. Wenn der Vertrag im Erwartungswert Geld bringt, muss man ein paar Dinge mehr beachten
@sean_ulm @ingmarschlecht Nein, keine konkreten Vorgaben über abstrakte und von allen existierenden CfD streng genommen nicht einhaltbare Anforderungen hinaus
