- 🚨new pub!🚨 link.springer.com/article/10.1... W/ S. Baert, L. Halewyck, E. Moens, A. Vandromme We show that small differences in age at school entry can meaningfully shape early career outcomes. A short overview 👇
- Using rich Flemish survey data and a 2SLS strategy, we study whether being older than one’s classmates due to school entry rules affects the transition from school to work.
- Being almost one year older within a cohort increases the probability of employment one year after graduation by 3.5 p.p., and raises the likelihood of obtaining a permanent (+5.1 p.p.) or full‑time (+6.5 p.p.) contract.
- Mediation analyses indicate that part of this effect operates through educational pathways: older students are less likely to experience delays and more likely to have student jobs. These factors explain some—but not all—of the relative age advantage.
- 🚨new pub!🚨 We study a novel education-based determinant of adolescents' dietary behaviors: the within-class age difference, referred to as relative age. w/ @svenahartmann.bsky.social & Francesco Principe. www.sciencedirect.com/science/arti...
- We find that younger within-class students are more likely to be objectively and subjectively overweight, and more likely to be on a diet. Plus, they eat more sweets and soft drinks, and less fruit and vegetables. They are also less likely to eat breakfast regularly on school days.
- These results are robust across macro-regions and countries, although they are mitigated in countries with universal school provision.
- The findings highlight the importance of policies and interventions that address age-related disparities in schools, such as targeted nutritional programs, peer mentoring, and flexible grouping strategies, to promote healthier outcomes for all students.
- Hi #econsky folks! I am enjoying Paper Skygest! It is a personalized, curated feed, linked to the account @paper-feed.bsky.social, created by @sjgreenwood.bsky.social and @nkgarg.bsky.social!
- here is the intro post by Nikhil bsky.app/profile/nkga...
- *Please repost* @sjgreenwood.bsky.social and I just launched a new personalized feed (*please pin*) that we hope will become a "must use" for #academicsky. The feed shows posts about papers filtered by *your* follower network. It's become my default Bluesky experience bsky.app/profile/pape...
- And here arxiv.org/abs/2601.04253 is the introductory paper posted by @sjgreenwood.bsky.social on arxiv.org

- Reposted by Luca FumarcoThese authors wanted to know whether people with physical disabilities face discrimination in hiring: even when they are equally qualified. So they ran an experiment.
- Hi lovely #econsky people! 📢 Call for Papers: YEM2026 – Young Economists’ Meeting, Brno (yem.econ.muni.cz). Submit full papers or extended abstracts by Feb 28 for the conference on May 27–29, Brno, Czech Republic. We can’t wait to see you there! #YEM2026
- Reposted by Luca Fumarco🧪 Some really important data points in here to share with others. Over the past year, Bluesky has 5 million research posts (0.25% of the total traffic). Compared to the 11.2 million research posts on Twitter (0.000006% of the total traffic). Bluesky is punching above its weight! #AcademicSky
- THREAD The first full year of tracking research on @bsky.app Hi, we are Altmetric, and we track how research is communicated across the web. We now have one full calendar year of Bluesky research data and thought we'd have a looksie.
- I have just uploaded my #econ5k at @econ5k.bsky.social. It was on a Jan 1st. Looking back at the time, I can only guess that vitel tonnè, insalata russa, türtlin, bagna cauda, panetün of those days did not help much 🏃
- Once, a colleague told me: "Using a particular dataset is not, by itself, a contribution." I mostly agree. But I also feel that in many papers the main contribution is access to a particular dataset — and it’s often framed that way. 1/7
- The existence of great, easily accessible, pre-packaged data shapes how we spend our research time. If you have an amazing, cleaned dataset, you can pour energy into identification, modelling, and robustness. 2/7
- If you don't, you pour months or years into scraping, merging, cleaning, and documentation. That work is essential but barely rewarded, and it crowds out time to build more "visible" econometric skills. 3/7

View full threadFor empirical applied micro, shouldn't "data acquisition" be a core methods course — on par with experimental methods in behavioral econ? If getting the data is half the battle, why do we treat it like an afterthought? 7/7

- probably the best comment I have ever received in a referee report, it opens as this: "I decided that I hate referees who seem to ask for changes just so that they look like they did something, and thus I would just send you this big thumbs up, with two very small comments..."
- it is a great relief to see that the main @iza.org activities will proceed under @liser.lu (e.g. world of labour, wp series, summer schools, visiting programs). this is a couple of weeks old news, but many of us were still on vacation. newsroom.iza.org/en/archive/n...

- Hi marvellous #econsky! I am new to PSID data. What variables shall I use to merge cross-year individual data to transition into adulthood data?
- hi @umpsid.bsky.social ppl, any suggestion?
- 🚨#econsky ppl🚨 Submit your work to the 2nd International Virtual Conference on Ukraine. "Leading scholars as well as researchers at all career levels are invited..." All details here: www.kth.se/ukraine-conf...
- great visibility and network opportunity, submit your papers!
- #YEM2025 was a blast, as usual. W keynotes @dkuebler.bsky.social & @neumarkecon.bsky.social. Great papers from participants & the best paper award to @juliaengel.bsky.social.
- btw, #econsky, it is great to be at @econmuni.bsky.social. in a landscape of decresing funds and increasing competition, consider applying here for future positions. 2/4
- reasonable to no teaching (depending on contract), lots of flexibility, expanding network, great ppp salary and quality of life, funds (both competitive and not), regular MUES seminars w guests from all over europe. 3/4
- it is easy to keep in touch with your network as you are not asked to spend all your time phisically in Brno (e.g. 70%). when you will be on the job market, consider applying here if you see an opening. you ll develop your research agenda & have a concrete impact on a rapidly growing institute. 4/4
- Over a few days, I have saved a few spare hours for myself. I have >1500 (mostly running) activities on Runkeeper since 2013. I guess I have to use Stata for a non-economic project.

- #econsky #EconJobMarket Post-job market suggestion (specifically in Europe). There are two things that I realized too late: 1) you might be willing to change institute type (e.g. uni vs research institute), and 2) you might be willing to change country. Hurray for the flexibility. However... 1/5
- be strategic: different institutes and places, have different publication requirements (sort of departmental or national catalogues of journals to assess your productivity). So, try to have clear goals, make your publications bang for the bucks--even when they are not top publications. 2/5
- Try to find that intersection of publication requirements, so that your research output is transferable and counted across institutes and countries. Top journals are assessed positively everywhere, but any other journal not necessarily. 3/5
-
View full threadWith a clear goal (e.g., go back to country x or move back to academia), it is easier to find the intersection between the set of outlets well rewarded in your current institute type/country and the set of outlets well rewarded in the institute type/country where you would like to end up. 5/5
- However, I feel that after an initial enthusiastic period that lasted a few months, Blusky is not gaining further momentum with #econsky ppl, or? I do not see the sparkling atmosphere as on the other place
- This has been an awesome and timely project to work on! Thank you @nickchk.com for organizing this and involve us!
