Economics.

Here is a rock song "HC1 Heartbreak" (MP3 and Lyrics) econ.mathematik.uni-ulm.de/aisongs/hc1_... based on my research paper arxiv.org/abs/2411.14763 on robust standard errors and large scale methodological replications. Made with Suno and ChatGPT. AI amazes me again and again.

“Replication is an ethnography of science, a reflection by the scientists themselves on the scientific process and the challenges of producing results, while being engaged in that very process.” New ethnographic work by Brenninkmeijer et al. Open Access: doi.org/10.1177/0306... 🧵

Our Leibniz Open Science Day, 'Better Science for Better Policies', is taking place tomorrow in Berlin, with an exciting programme of interesting papers - check them out. The meta-scientific community is really taking off! www.zbw.eu/de/ueber-uns...

Apparently some folks are playing real dumb about skull symbols so let’s play a little game I like to call “Nazi skull or not a Nazi skull” First up, the Jolly Roger. This is a pirate skull, not a Nazi skull. It means you might get robbed, but prolly not genocided. With me so far? 1/x

On data quality in surveys run by Prolific, M-Turk etc.

Is there actually any research on the quality of papers based on Prolific, as there was for M-Turk?

No, the "experimental evidence" fallacy. This paper is based on a prolific.com experiment, complemented by some MBA students. Participants were asked to *imagine* (!!) they were certain decision makers. Nothing against this empirical attempt – but calm down and perhaps tone down the paper. 1/3

New in JCRE: “Public Infrastructure and Economic Development: Evidence from Postal Systems A Replication Study of Rogowski et al. (American Journal of Political Science, 2022) by @florianneubauer.bsky.social , Julian Rose and @jrgptrs.bsky.social " www.jcr-econ.org/public-infra...

I thought this was quite a nice (and appropriately pessimistic) discussion of our paper on power in political science. All that I would add is that we found a small minority of research topics with high power! podcasts.apple.com/ca/podcast/i...

We are hosting this year's MAER-Net Colloquium on Friday and Saturday. The program and more information are available here: www.maer-net.org/2025-ottawa Plenary sessions (with Andrew Gelman, Shinichi Nakagawa and others) and some parallel sessions will be live-streamed for free

In fact, the conclusion is clearer than the rather conservative title suggests. "No evidence" is what you say when your null effect is inconclusive. A Bayes Factor of 66 for the null would seem to constitute "Positive evidence for ineffectiveness...". Time to give up and try something stronger!

What do experts think about the famous Acemoglu et al. (2001) – Albouy replication debate? In our new discussion paper, we show that there’s no consensus among them. @jrgptrs.bsky.social ’s thread tells the story: bsky.app/profile/jrgp...

There are 2️⃣ ways to make it in economics. 1️⃣ AJR's way : take a consensual general claim and "prove" it with a dubious instrument. 2️⃣ The other way : take a contrarian general claim and "prove" it with a dubious instrument.

Further robust evidence suggesting green nudges at the individual level are unlikely to make a difference. As we recently suggested, it is time to abandon the prevailing success focus and rather think of this body of evidence as pointing to the many structural constraints people are facing, and

Thought about scientific consensus recently? We have a new DP @i4replication.bsky.social that probes into the famous replication debate between Acemoglu, Johnson & Robinson (AJR) and Albouy - and how experts assess this debate. We find that they disagree. 1/8 www.econstor.eu/bitstream/10...

I'd lie if I said I am surprised.

New piece on growth dependence out in Futures. To account for the possibility that environmental sustainability can only be achieved with lower economic output, this study carries out a thought experiment in which ambitious environmental policies result in economic contraction.

Deeply honoured to receive this award from the Academy of Sociology with my co-authors! I hope we’ll see many more replications in Sociology in the years ahead, along with preregistrations and registered reports as leading journals make more space for them. #AkadSoz25 #sociology

New DP @i4replication.bsky.social: Meta-analysis on green nudges correcting for publication bias. "Behavioral interventions on households and individuals are unlikely to deliver material climate benefits." www.econstor.eu/bitstream/10...

Today is the day!!! Existential Politics is out in the world! Read about why we’re doing climate policy wrong (too focused on measuring emissions) & what we should do instead (focus on $$ to constrain fossil asset owners & expand green asset owners). Just in time for #COP30.

🌍📈 Paper “The Economics of Inequality and the Environment” out today in the Journal of Economic Literature @aeajournals.bsky.social, joint with Jasper Meya, Lutz Sager & Ulrike Kornek. See short summary and PM by PIK linked below, and the paper here 👉 pubs.aeaweb.org/doi/pdfplus/...

New publication: Designing Carbon Pricing Policies Across the Globe with Robert Schmidt and @moritzdrupp.bsky.social in Environmental and Resource Economics! We present the largest international expert survey on carbon pricing design (400+ participants, ~40 countries). Some highlights.

Insights into Elsevier's business model. "Publishers trade off higher returns in the short run with maintaining prestige in the long run." And I even guess this long-term-prestige objective only applies to upper tier Elsevier journals like Energy Economics.

My article "Data is not available upon request" was published in Meta-Psychology. Very happy to see this out! open.lnu.se/index.php/me...

Das kann doch kein Zufall sein.

At @i4replication.bsky.social it is our ambition to foster a replication culture in the social sciences – and we hence welcome if our approaches are replicated as well: Replication Games on using LLM in experiments, in Valencia and Oxford. talkingtomachines.org/projects/ime...

I occasionally read econometric instrumental variables (IV) literature, and I am always struck by the mismatch between the premise of these econometricians that IVs are used to generate knowledge and the truth that IVs are actually used to generate interesting results for highly ranked publications.

No pun intended!

Coding errors in data processing are more likely to be ignored if the erroneous result is in line with what we want to see. The theoretical prediction made in this paper is very plausible - testing it empirically is perhaps a bit more challenging. But still, interesting. arxiv.org/pdf/2508.20069

I4R Replication Games coming to Münster! @i4replication.bsky.social @aufdroeseler.bsky.social @fialalenka.bsky.social

Come to the #VfS panel on #OpenScience with Severine Toussaert, @leventneyse.bsky.social @jrgptrs.bsky.social @larsvil.bsky.social . Looking forward to the discussion.

The pretty draft is now online. Link to paper (free): www.journals.uchicago.edu/doi/epdf/10.... Our replication package starts from the raw data and we put real work into making it readable & setting it up so people could poke at it, so please do explore it: dataverse.harvard.edu/dataset.xhtm...

The Replication Games is a one-day event that brings researchers together to collaborate on reproducing and replicating papers published in high-ranking journals. There is still time to register for the Berlin Replication Games on 30 September.

🚨 Last chance to join the Berlin Replication Games! Registration closes this Friday, September 12.

This new study shows: in Germany, it has become much harder for children to earn more than their parents, now about as hard as in the US: "parental income has become much more important for educational outcomes of children"

Hey #EAAE2025: Thursday is replication day. First, Anna Dreber's keynote on "Predicting Replication Outcomes" (11am) & our session👇(4pm) feat. ‪@robertfinger.bsky.social‬ @cedricchambru.bsky.social‬ @jensrommel.bsky.social‬ ‪@beta1hat.bsky.social‬ @mabuchner.bsky.social‬ ‪@i4replication.bsky.social‬

#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) 🧵

Really looking forward to this!
