📚 New study on #Kenya by @pbiscaye.bsky.social @eggerdennis.bsky.social & Utz Pape When schools reopened after #COVID closures, parents worked more, because kids had less time for farm work. Adults filled the gap, while richer households hired labor. 🔎 Read more: t.ly/wzH7g 📄 #econdev #school

Bonus of working late is I am much less annoyed about being called by my almost three year to put her blanket back on her because she is cold than if I had already been asleep. I get to enjoy a sweet parental moment instead of mentally grumbling that she can put her own damn blanket back on 😆

@leightjessica.bsky.social regularly posts threads highlighting the work of young economists and today I am fortunate that she has chosen to highlight some of my research! I encourage anyone not already doing so to follow her - she has introduced me to many cool researchers 🤩 Thanks again Jessica!

Why not a 211 team tournament??They could even have the preliminary rounds organized by continental league, to reduce travel - and allow more host nations to get in on it! Maybe then the top few teams from those tournaments could meet in some sort of final tournament in a rotating host country… 🤔🤦‍♂️

Better late than never. . .this week's cool young researcher #econtwitter #econsky is @ellenmcc.bsky.social @ellen_mcc who works on topics related to agriculture, labor + nutrition

Used to go to bed much later Fridays and Saturdays, staying up with friends and loved ones. Now I prize weekend nights as ones where I can permit myself to go to bed early rather than staying up to work. Love the work but it never ends! Guess that’s why I get the small 💰💰 #Academia #EconSky

Highly recommend listening to the Scam Inc podcast series by @economist.com. Eye opening and a bit scary. Never realized how huge and advanced the whole global scamming industry has become. First half of the series is available free and well worth a listen.

@cerdi.bsky.social will host the 2025 EUDN PhD workshop in Clermont-Ferrand, France on May 15-16 with Roberta Ziparo (@amseaixmars.bsky.social) as keynote speaker. aA great opportunity for PhD students to network and get feedback. Please share the below call for papers! eudn25phd.sciencesconf.org

Two wins over City in one day! A barn-buster and a beat down. So sweet. #COYG @arsenalfc.bsky.social

PhD students consider submitting to our annual conference run by and focused on doctoral students in economics. April is a nice time to visit Paris docs.google.com/forms/d/1u7v...

Gave my first economics (micro development) lecture in French today! It went pretty well but translating terminology off the cuff will be tough. Terms I learned during my lecture: -standard error = écart type -shadow wage = salaire au noir -derivative = dérivé #EconSky 🇫🇷

With @jeromevalette.bsky.social & Simone Bertoli, we are thrilled to announce the Call for Papers for the 3rd edition of the Junior Workshop on the Economics of Migration on 23-24 June 2025 @CERDI, Clermont-Ferrand, France. Submit until 23 February 2025 on economig2025.sciencesconf.org

Enjoyed a great short trip to Copenhagen for the STEG ag and structural transformation workshop. Super cool group of researchers and a great time of feedback and discussion. Thanks @casperworm.bsky.social and Asger Wingender for hosting 🙏 I still can’t get over all the unlocked bikes! #EconSky

Observations from first visit to Copenhagen: There are bikes everywhere! 😍😍😍 Most bikes are unlocked!! 🤯🤯🤯 Most bikers aren’t wearing helmets! 🤕🤕 Interested if anyone has insights about the lock and helmet habits. Otherwise seems like a quite nice city, wish I had more time to explore.

Do other parents with 2(+) kids find it less hard when they get sick both at once or back to back? Both at once is super hard on everyone but over quicker. Back to back is easier to manage in some ways but draining and disruptive and I always end up sick too. Of course, we don't get to choose. Wooh!

The climate–conflict nexus is an active area of research. I examine how El Niño Southern Oscillation (ENSO) shocks affect political violence in Africa. Headline result: Exposure to a positive ENSO shock (an El Niño event) reduces postharvest conflict. [1/13] doi.org/10.1111/ajae...

I've posted several times about the working paper, but the publication on "AER: Insights" is a good occasion to do it again: immigrants to the US have been less likely to be incarcerated for over 50 years **even without controlling for demographic characteristics.** www.aeaweb.org/articles?id=...

What a week for @arsenalfc.bsky.social. 13-3 across 3 matches! After a run where we were struggling to score, looks like the international break really did us some good. #COYG keep it up!!

One of the hardest adjustments to biking/driving in France: T intersections with no stop or yield signs or roundabout where for some insane reason if I’m going straight I’m supposed to yield to a person coming from the right that is turning onto the road I’m on. What is the reason for this??

Hi #EconSky, Not sure if the Starter Pack party's over, but I've made an Econ Starter Pack of Starter Packs! 😄 It's a work in progress, so I may have missed some. Let me know if there's anything to add—DMs are open! Thanks for support @economista.bsky.social! docs.google.com/spreadsheets...

To all the new #EconSky people whi may be dealing with the Econ Job Market: *There is an #EconJMP feed *I have a PhD Job Market Starter Pack go.bsky.app/4icnwxi. If you are a candidate or an institution posting *many* openings, reach out and I will add you.

I'm excited to kick-off our annual series of posts by PhD students in development on the job market with @mrao.bsky.social 's post on whether & when evaluation evidence affects spending on CCTs using 128 program evaluations in Latin America. blogs.worldbank.org/en/impacteva...

I’ve never walked the gangplank and I’ve never owned a parrot, but now I have been to Boston in the Fall! 😆 Great conference #NEUDC2024 and enjoyed the visit as well. (For the reference: www.youtube.com/watch?v=aRYB...)

A 1 hour time change shouldn’t be such a big deal. My body and a body of evidence say otherwise. But since nearly all personal use clocks now are digital, why don’t countries implement #DaylightSavings in 15 minute increments over 4 weeks? Seems like an easy win policy change. #FallBackSlowly

I used to be productive on many weekend afternoons. Now I fall asleep in the middle of playing or reading. #parenting

📢Please retweet📢 Profs Van Benthem, Lockwood, Low, Rees-Jones, Kessler and I are hiring 3 predoctoral researchers (in environmental, behavioral, and public econ) to start July 2025. Prior RAs got into Berkeley, Princeton and Brown (econ PhDs). Rolling review: sberkouwer.github.io/BEPPhiring.pdf

Grateful for the great comments and feedback on my paper on ag shocks and long term conflict at the #FragileLives conference at @humboldtuni.bsky.social in Berlin. Thanks to the organizers for a great conference! #ISDC #HiCN #IGZ #ZeroHungerLab

It's probably been done, but...

Thanks for reading! I’d love to talk more about my JMP and other projects (🌊 in 🇳🇬, 🔌 in 🇬🇭, 🦗 in 🇲🇼, and more) with anyone who is interested.   Paper: tinyurl.com/kbdf2fdz Website: pierrebiscaye.com   13/13

Key takeaway: ↗️ long-term conflict means negative ag shocks have worse consequences than previously understood. Permanent income ↘️ appears to be the mechanism   Moving forward: 1️⃣ HH survey data on wealth, productivity to dig more into mechs 2️⃣ Role of aid/institutions in mitigating conflict ↗️ 12/13

Is there something unique about desert locusts? No! Severe drought exposure leads to similar long-run increases in violent conflict risk. Methods estimating temporary effects of economic shocks on conflict with FE models may thus underestimate impacts.   11/13

This explains why the largest impacts of swarm exposure are delayed. 73% of exposure was in the 2003-2005 locust outbreak, but violent conflict incidence was low in these countries until ~2010 due to food price shocks, Arab Spring, Islamic militant groups, etc.   10/13

This reduction in productivity-consistent with a wealth or permanent income mechanism-means the opportunity cost of fighting is lower. But conflict risk only increases in years with violent conflict in surrounding cells: when there are opportunities to fight.   9/13

Why does a one-time production shock persistently increase conflict risk? Although locust swarms do not return, I find that affected cells have 108 kg/ha lower cereal yields on average post-exposure, similar to the effect of a 1 degree C temp increase.   8/13

Estimates weighted by the inverse of the estimated probability of swarm exposure give a 0.8pp avg increase in annual risk of violent conflict after exposure, driven entirely by ag land, particularly crop cells. This greatly exceeds effects of same year rainfall or temp ⬆️s!   7/13
