Every year South Asia’s brick kilns spew as much CO₂ as the entire U.S. car fleet. They poison the air 2B people breathe—and kill over 50,000 annually A new study in Science supported by Stanford Impact Labs Open Philanthropy & J-PAL shows how simple fixes can clean air & cut emissions🧵⬇️

This new paper in Science exemplifies exactly the kind of Dev Econ research I get excited by. Building blocks for initiatives that could be truly transformative for welfare. Great summary thread below Huge congrats to Aprajit Mahajan and all coauthors!

4/ So we’re opening a new line: The Lux Science Helpline. $100M of additional funding to bring labwork to reality. No RFPs. No five-year plans. Just fast action.

Today's cool young researcher #econtwitter #econsky is Siddharth George NUS who works on topics related to development, political economy + labor

Air pollution. Cyclones. Ocean waves. A single AI model now outperforms some of the world’s best climate prediction systems. And it runs 100,000x faster. Here’s the breakdown:

No one had more cumulative influence on the macroeconomic policy makers of the last generation than Stanley Fischer. Central Bank governors Ben Bernanke, Mario Draghi and Kazuo Ueda were his students, as were many others like me, who served in other capacities. We all were shaped

🚨New NBER WP🚨 We use data on 42,000 households in #India to study how the agricultural sector copes w/ labour loss. As #farmers move to cities for higher wages, their left-behind families *don't* substitute with increased capital -- they downsize their farms. (1/2)

Stan Fischer's passing is a profound loss for the global economic community. I learnt a lot from Stan's textbooks and the conversations we later had. Stan's intellectual rigor, thoughtful teaching and service across institutions will be long remembered at IMF.

Jason Kerwin Use cases for LLMs for me so far 1. Coding 2. Non research tasks (summarising my work for grants, briefs, reports, etc) 3. Early lit review (deep research is good here) 4. Small writing tasks like abstracts (I could use it more here, but I’m still somewhat averse to the idea).

It is a very good thing for the U.S. that all the world's elites spend time at our universities—absorbing our culture, our ideas. If they stay, we get their talent. If they leave, they spread our beliefs in openness and entrepreneurialism. It is foolishness to push them away.

The secret's out... I’m proud to share that The LBJ School is launching a Master of National Security program. This new degree will prepare the next generation of national security leaders and marks an exciting step forward for our school and for the future of public service. 🤘

astralcodexten I like this "Hero License" idea as well. I experienced this when I did a Masters at Harvard, having attended the University of Calgary. There were all these people with great ambitions and self-confidence, who were smart, but not like so much insanely smarter than me. And I

A proposal to build on the success of congestion pricing by adding zones and raising fees

Our new study is the 1st global analysis of climate change’s impact on staple crops to account for real-world adaptation measures taken by farmers, applying measurements to projections of ag damages. We find: those with the most to lose, lose the most: impactlab.org/research/impac…

This is an incredible tragedy: "Perhaps the most striking finding is that younger generations today are much more zero-sum than older ones." economist.com/by-invitation/…

Thank you, Kalamazoo!

Energy Policy Institute at The University of Chicago Director makes the case that societies must balance 2 urgent goals: economic growth & climate risk, highlighting why climate action can’t come at the expense of human development & how Energy Policy Institute at UChicago is working to make that balancing act easier.

Excited to announce a new funding opportunity for research on "what works" in climate adaptation. We are specifically looking for strong causal designs that tell us what interventions work (or don't) to reduce impacts of a changing climate. Link in next post. Plz share!

I'm still deeply confused why every town does just set permanent speed cameras and fine everyone going more than 10mph over the limit. You could eliminate speeding and improve safety immediately. 2/

🔥🚗🚗 Here we go, short-run effects of congestion pricing in NY. I feel like Twitter already figured this one out, but looking forward to seeing what Vasserman et al have to show us
