Incentives to reproduce and replicate articles are so bad. Even when your comment leads to the retraction of a PLOS One article, the reward is a (10 days late) email with a thank you at the bottom. Retraction notice: journals.plos.org/plosone/arti.... But we are not complaining about PLOS One 🧵

#GDRI_rep Update 10 The orphan article has finally been retracted! Took more than a year, but at last. Read about our investigation (bsky.app/profile/i4re...) and updates ( #GDRI_rep). A good summary: a-ortmann.medium.com/the-asad-isl... and a-ortmann.medium.com/tallying-the...

#GDRI_rep Update 9: We have been waiting a couple of months to make two announcements. A few journals were in the process of retracting GDRI article. The editors informed the authors and then lawyers got involved. Who knows how long it will take.

New working paper! *Measuring long-run wealth inequality: Empirical results for Norway 1912-2019* (with Aaberge and Solbakken) We estimate wealth inequality in Norway based on a set of historical and contemporary sources. www.ssb.no/en/inntekt-o...

🚨 Our comment on Begum, Grossman & Islam (2018) in @readdemography.bsky.social is now available as an @i4replication.bsky.social working paper (w/ @carlbonander.bsky.social, @nikljako.bsky.social, Bensch & Brodeur). Read it here 👉 www.econstor.eu/bitstream/10...

#GDRI_rep Update 8a: Major updates coming up over the next few weeks. 1st update: We reproduced "Parent–teacher meetings and student outcomes" some time ago. The paper was then retracted by the editors of the Euro Econ Rev. Additional studies are connected (see diagram) 🧵

Important paper from @anderskjelsrud.bsky.social and Sahar!

Female PhD students (in economics) benefit tremendously from having female faculty around. When female professors go on leave, it decreases third-year female PhD students’ likelihood of publishing & securing academic positions. papers.ssrn.com/sol3/papers....

Update: We submitted the comment to the Journal of Population Economics, and today we got a desk reject with this motivation. However, we do not know their conclusion about the main results and why the paper was not retracted. Clearly, they do not hold. 1/4

🚨 REPLICATION REPORT UPDATE: One year ago, a tweet by John Holbein alerted me, @ollefolke.bsky.social, and @jopieboy.bsky.social to a paper with a shocking result about Sweden’s law criminalizing the purchase of sex.🧵

🚨 New #EconHistory research alert! Our paper “Strikes & Machines: Investment decisions in inter‑war Norway” conditionally accepted in Journal of Economic History ask "What did strike threats really do to technology?" 👇 1/6

#GDRI_rep Update 6: Some of the authors have responded to our report on "Raising Health Awareness in Rural Communities" @ The Review of Economics and Statistics. Authors received our report Feb 6. A short 🧵

This gem is hidden in the response to the response. ”…within a few hours and under extreme time pressure 11,843 households were visited and 22,686 respondents interviewed (two spouses in each household).” Indeed hard to believe 🫠

#GDRI_rep Update 5: We have a new report. We reproduced the paper entitled "Partisan Effects of Information Campaigns in Competitive Authoritarian Elections: Evidence from Bangladesh" by Ahmed, Hodler and Islam published at the Economic Journal. See below for links to report and authors' responses.

In a new @i4replication.bsky.social report we replicate Islam (2019). Main issue: the randomized controlled trial was not randomized. And many other things on top of that. See full report for details. (w/ @carlbonander.bsky.social, @nikljako.bsky.social, @flxhlzmstr.bsky.social, Bensch & Brodeur)

#GDRI_rep Update 2: I4R sent a report to the original authors for the PLOS One article "“Food insecurity and mental health of women during COVID-19: Evidence from a developing country". All authors have now emailed PLOS One to withdraw their names. osf.io/7tzek/

Institute for Replication@i4replication.bsky.social · last yr.

We completed a full report on “Food insecurity and mental health of women during COVID-19: Evidence from a developing country” PLOS One and shared it with the authors and journal. Two out of three authors have already requested to withdraw their names.

#GDRI_rep Update 1: I4R are now reproducing all published papers that use data from GDRI, or are closely related in other ways. Here is a first update on our work. 🧵

Opprop! Vi er 47 samfunnsøkonomer som tar til orde for en kraftig økning av Norges støtte til Ukraina. www.aftenposten.no/meninger/deb...

Handlingsregelen må ikke stå i veien for en kraftig økning av Norges støtte til Ukraina

Ved å gi Ukraina det landet trenger, gjør vi nettopp det handlingsregelen var ment å gjøre.

👏 Good news for researchers working with Swedish register data and who want their research to be reproducible 👉 If you include in your ethics application/research plan that replication may be part of the project, then external replicators (e.g. data editors) can be given access to the data!

Abel: I am writing in my capacity as Chair of I4R. Last year, I was contacted by a researcher that alerted me of potential scientific misconduct in a set of papers all using data from a specific NGO.🧵
