One of the comments that we wrote has now led to a retraction. The editorial board explains their decision making process and all the outcomes here: https://t.co/rp84Dr2Vzp

#GDRI_rep Update 10

The orphan article has finally been retracted! Took more than a year, but at last.

Read about our investigation (https://t.co/owLB4DjqO2) and updates ( #GDRI_rep).

A good summary: https://t.co/exEYTLMMRb and https://t.co/wgFypen31B

Jack wrote a nice summary of our project on log-like specifications. Do not use inverse hyperbolic sine, ln(Z+c) transformations to get around the fact that ln(0) is undefined. These models have very unstable t-statistics wrt unit scaling and serious non-robustness issues.

[Jack Fitzgerald | @jackfitzgerald.bsky.social @FitzgeraldJack_]

New preprint! We re-analyze 46 papers that use log-like specifications (ln(Z+1), inverse hyperbolic sine, etc). We find widespread non-robustness, and we show through theory + simulation how these models drive spurious significance. 1/

Tästä faktasta eivät persut ja kokoomuslaiset tykkää, mutta postataan silti.

Suomen sotu-menojen ongelma ei ole työtä etsivä toimeentulotuen asiakas saatika ne ”ideologisesti työttömät”.

Väestöllinen huoltosuhde ei ole koskaan sopinut oikeistolaiseen narratiiviin.

Björn Wahlroos kirjoittaa tuoreessa kirjassaan Etlan johdon vaihtumisesta vuonna 2019. Kirjoitus antaa aiheen pohtia etujärjestöjen rahoittaman tutkimustoiminnan roolia ja vähän laajemminkin asiantuntijatietoon pohjautuvaa päätöksentekoa Suomessa. https://t.co/2mRVyZVHAL

@florianederer There is a paper investigating this: "Is economics self‐correcting? Replications in the American Economic Review" by Jörg Ankel‐Peters, Nathan Fiala, and Florian Neubauer https://t.co/R5RR4uQLin

David Roodman writes: consumers of economic research are more truth-seeking than the producers.

Here is Roodman's recap of his re-analysis of a set of papers on temperature and judge decision-making.

The comment process is not working that well!

Update 8b:

Read 🧵8a and others here #GDRI_rep.

Our diagram hints at other studies linked to EER. We refer to many of these studies as the cyclone papers. We reached out to the Journal of Risk & Uncertainty about this paper: “Natural disaster and risk-sharing behavior”...

[I4R @I4Replication]

#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)

It wasn't me this week, but I have encountered the same problem many times. I wonder, do not these people know how the internet works?

[I4R @I4Replication]

We did not want to start the week like this, but here we are. Yet again our chair’s inbox is filled with messages from replicators who have opened “replication” folders only to find names, Social Insurance Numbers, mental-health diagnoses and incomes of study participants. 🧵

[Philipp Heimberger @heimbergecon]

Investigative journalists found that the Finnish finance ministry selectively cited our study (with @SGechert) on the growth effects of corporate tax cuts to back the ministry's claim that planned tax cuts will largely pay for themselves. Our main result is inconsistent with this

Half of children died. A thread. 🧵

#GDRI_rep Update 7: Retraction! Our comment of "Parent–teacher meetings and student outcomes: Evidence from a developing country" has led to the paper being retracted. Our comment is accepted as is.

Short 🧵

[I4R @I4Replication]

We will publicly release these reports shortly.

We have requested several replication packages over the past months. Unfortunately, we have not yet managed to get a single new replication package as of today (excluding updated packages for one article at the request of editors)

[I4R @I4Replication]

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

[Essi Kujansuu @EssiEconomist]

"No reason" is the most common reason for retracting a paper in economics. Sounds like a "no problem" to me.

[Science Banana @literalbanana]

@jrgptrs @RexDouglass I was so blown away by this I had to look into it - these guys claim 55 retractions ever by 2018 but only TWO were explicitly for research fuckery which is maybe what you're pointing at? https://t.co/5AhT2XsbnT
