#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.

This will likely be a good initiative, conditional on it not substituting for the journal publishing full comments. Publication is an important incentive for reproducibility/robustness analyses and substantive empirical critiques almost always take more than one page.
We are pleased to announce an experiment intended to stimulate academic discussion and exchange, centered on papers published in Econometrica 1/5

#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.

Thank you @carlislerainey.bsky.social for boosting my job market paper! I’’m a fan of your prior work on this topic.

If you want to learn more, check out the paper and my BIBAP seminar on it tomorrow, 3/12 7 AM CET/5 PM Sydney time.

#5 Here's another recent critique of close elections RDDs.

It's unclear whether there is actually good evidence against potentially fatal precise manipulation around the cutoff in these designs.

I'll be waking up early (7 AM CET) on Tuesday, March 12 to present my job market paper at 5 PM Sydney time! If you're awake too, stop by to hear me talk about equivalence testing, replication-based methods research, and the robustness of null results in economics!
March 7, 2025 at 10:53 AM
Relatedly, I also develop new equivalence testing methods for testing running variable (RV) manipulation in RDD. In 36 RDD publications, I find >44% of RV density discontinuities at treatment cutoffs can't be significantly bounded beneath 50% upward jumps. 🧵: bsky.app/profile/jack...
Lots of talk on X today about rethinking the results produced by close elections RDDs.

So, I thought I'd drop a few recent articles about issues that arise in this space so that folks can have them all in one place. 1/N

#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/

#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. 🧵

Our proposal for post-publication review: “our system would add only 1 percent to the total reviewing effort, while providing important perspectives on papers representing more than one-quarter of the citations received by these influential journals.”

As a coauthor on the AEJ:AE report, it’s a lot. Oh my god, It’s a lot. In that paper, outcomes are inconsistently handled both in the code and in the field, the paper’s data is connected to a bunch of other experiments, and we find irregularities in the raw survey files.
After being alerted about possible misconduct, the I4R are reproducing published papers that use data from a specific NGO (GDRI). This thread releases the first 2 reports and provides more information about the work and responses/statements from authors journals and journals. 🧵

I had a wonderful time presenting my job market paper at RWI Essen! Thank you @jrgptrs.bsky.social and Julian Rose for hosting and organizing!
Last week we had @jackfitzgerald.bsky.social with us presenting his work on equivalence testing. Economists typically interpret null results as the absence of an effect. This is wrong. Proper testing is particularly important for robustness checks in IV & RDD settings www.econstor.eu/handle/10419...

New working paper! @i4replication.bsky.social does a good job detailing the experiment’s results, so for anyone who considers LLMs/AI as a (soon-to-be) solution to reproducibility in social science, let me walk you through the 🔥hell🔥 of trying to reproduce a paper on an "AI-led" team. 1/7
New research alert! Our study investigates the effectiveness of human-only, AI-assisted, and AI-led teams in assessing the reproducibility of quantitative social science research. We've got some surprising findings!

New paper for holiday reading! @isager.bsky.social and I provide an introduction to three-sided testing, a framework for testing estimates' practical significance. We offer a tutorial, Shiny app, + commands/code in #Rstats, #Jamovi, + #Stata. 1/9

A huge thanks to @sweiwang.bsky.social for highlighting my job market paper, The Need for Equivalence Testing in Economics!
#eeac Day 8 @jackfitzgerald.bsky.social argues in his JMP for the need to use equivalence testing for making null claims. He does a large-scale replication of estimates from more than 80 papers and provides goodies in State and R. jack-fitzgerald.github.io/files/The_Ne... #econsky #econjmp

Moving from Florida to the Netherlands is a trip because for three months of the year, you can look to the sky and think ‘wow, what a beautiful sunset’ before realizing it’s 2:30 in the afternoon
