Here is a list of economists on Bluesky — thanks Lukas for creating this Econ Starter Pack!

I tried to collect econ-related accounts that have a non-zero chance of posting here: go.bsky.app/RuagxpZ (happy to receive suggestions, incl self-nominations)

Non-technical summary of our (w/ @adegendre.bsky.social, @nsalamanca.bsky.social & Zenou) paper (www.nber.org/papers/w32429) on the effects of exposure to minority students for majority students, parents, and teachers now available via CEPR: cepr.org/voxeu/column.... We find modest negative effects

How students, parents, and teachers affect the integration of minorities in the classroomcepr.org Integrating ethnic minorities in the classroom enriches the educational environment, but some studies find that it lowers student test scores. This column explores what may drive such effects, using data from Taiwanese schools, where Indigenous students are randomly assigned to different classrooms. Students placed in classrooms with minority peers showed less effort, their parents invested less in their education, and teachers were less engaged, leading to lower test scores. Over a third of the drop could be linked to such reactions of students, parents, and teachers.

For the people who don’t have time, here’s your Readers Digest version. You’re welcome.

So agree!!

In the early Twitter days science types would show up and post when they had a new paper. Wonderful! But real talk y'all: papers take ages to write. So, post about other people's stuff! You read a paper and it was cool! Or you had a question! Or it tied to this other thing! Tag the authors!

So true

The internet archive is, like the high medieval, a selectively recorded chunk of calcified meanings and motivations from figures and institutions often long dead, whose unity exists mostly in retrospect. Still - a fine thing to go into battle for. So don those plates. It's time to become the Don.

Make sure to read this if your research is focused on policy evaluation and policy making! 👇🏽👇🏽👇🏽👇🏽👇🏽

Our paper with Stefano DellaVigna and Woojin Kim is now formally published in the JPE! So excited that this project has prompted a whole new line of research for us and for @thepeoplelab.bsky.social www.journals.uchicago.edu/doi/10.1086/...

We all know there are plenty of problems with the publication process in econ, but which ones matter most and how to address them? Please share your views with a joint AEA-EEA-ES-RES committee that will try to suggest solutions. Link to member survey: harvard.az1.qualtrics.com/jfe/form/SV_... 📉📈

Love this! Thanks for sharing! I don’t teach but I often find myself explaining my job to friends and family, and I found your list perfect. I love the bit about excluding “conclusions” that often alienate people eg about government intervention and markets. Thanks!

New post today! I join the long proud tradition of finding new ways to sum up the principles of microeconomics in a list of bullet points. I think it goes well! open.substack.com/pub/nickchk/...

Come do a PhD with us (at the University of Melbourne) and our colleagues at KU Leuven! The projects are in psych and metascience, evaluating the quality of evidence in various areas of psychology. Please share with students who might be interested!

Fancy doing a PhD at the crossroads of memory research, clinical psychology and metascience? And travelling the globe while doing so? Come work with @wolfvanpaemel.bsky.social @simine.com @tomhardwicke.bsky.social and me at KU Leuven and UniMelb and get a joint PhD degree! [please distribute] 1/2

@i4replication.bsky.social strikes back!! This is fantastic work. Lots of food for thought on improving the reliability of estimates and the quality of scientific findings.

New DP: econpapers.repec.org/paper/zbwi4r... Which AER papers were robust (in terms of the % of robustness checks significant at 5%) was predictable by our survey participants, but the survey participants were overly optimistic and overestimated the degree of robustness reproducibility

Paying researchers to focus on detecting errors is a simple idea that could may a big difference for the ability of science to self-correct. But perhaps more importantly research funding could include dedicated funds to “auditing”, and work contracts should account for time in this sort of service.

Science can be self-correcting — but only if we invest in making it so. Our view on the staggering costs of undetected errors in science, and why funding error detection and correction is less expensive, published today in Nature www.nature.com/articles/d41...

I did the math in 2019. The last time Tri-Council scholarships and postdoctoral funding in Canada was adjusted was in 2003. *In 2019*, basic inflation adjustments alone would have added $9,000 to Master's-level scholarships and more than $11,000 to PhD scholarships. Postdocs nearly $15,000.

Canada needs to make a major investment in graduate students and postdoctoral scholars in #Budget2024. It is no longer affordable for Canada's young talent to pursue research. #SupportOurScience @theglobeandmail.com www.theglobeandmail.com/canada/artic...

Universities ask federal government for additional funding in upcoming budgetwww.theglobeandmail.com The schools are also calling for an increase to the grants and stipends paid to young researchers
