#GDRI_rep Update 4: We have a new report. We reproduced the paper entitled "Parent–teacher meetings and student outcomes" by Islam @ European Economic Review. See below for links to report and author's response.

Oof. Replication of "Parent-teacher meetings" (EER 2019). "40 schools were selected randomly for the treatment. The remaining 36 schools served as the control group." The map of treatment and control schools: 1/

In a new I4R 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/ Niklas Jakobsson, Gunther Bensch, Bonander, Holzmeister & Brodeur)

New report just dropped. Time for a thread. You can find the replication report and the author's response in the linked thread (in the second tweet).

#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 responses.

Another day, another I4R update on the Islam - GDRI saga. And what a doozy it is. Not only a new report (and responses) but we learn that an R&R at JPubEcon by Islam et al was withdrawn and an R&R by Islam et al at JPE - Micro has now been rejected. No word from Monash yet.

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 🫠

This paper brings up a painful subject for transparency enthusiasts in economics: pre-registration is on the rise - but why only for RCTs where leeway & incentives for p-hacking/HARKing/publication bias are much smaller than in observational studies? 1/3 doi.org/10.1177/019384…

To add to this irony 👇: When you submit a paper to an AEA journal, you are asked to tick a box whether the study was pre-registered - but ONLY if you submit experimental work. 2/3

Cool new papers in the JHR!

#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 (REStat). Authors received our report Feb 6. A short 🧵

#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 🧵

A study by Nicolai T. Borgen, Lars J. Kirkebøen, Andreas Kotsadam, and Oddbjørn Raaum found that funding 600 extra teachers cut the student-teacher ratio by 10%, boosted student well-being and the school environment, but did not improve academics. jhr.uwpress.org/content/early/…

Which occupations carry the highest risk of sexual harassment—and who is doing the harassing? Our new study finds two distinct patterns depending on whether harassment comes from inside or outside the workplace. Paper link in comments and results summarized below. 🧵 1/

New research: Government support for religious groups can shape society’s values. The faith-based initiatives strengthened church–state ties. We find that these policies strengthened religiosity and conservative social attitudes. AEJ:Applied w/ lena lindbjerg sperling and Alessandro Pizzigolotto.
