“My parents could barely read or write. It’s been quite a journey, science allows you to do it.”
New laureate Omar Yaghi was in the middle of changing flights when we reached him, just after he heard that he had been awarded the 2025 #NobelPrize in Chemistry.
In this interview we speak about his early life as a refugee in Jordan and the overwhelming draw of the beauty of chemistry: “I set out to build beautiful things and solve intellectual problems.”

Preschools as a pathway out of poverty: Evidence from Mozambique
Last month on VoxDev, Marina Bassi (@wb_research), Bruno Besbas, @ile_din (@wb_research), @saravana_econ (@LKYSch) & Ana Reynoso (@umichECON) discussed a preschool construction programme: voxdev.org/topic/education/p…
In today’s Development Impact Blog, Alaka Holla and I share 5 concrete ways to reduce bias in meta-analyses—drawing on lessons from our global review of preprimary edu. programs. From study selection to analysis, we show how transparency and rigor matter.

Proud to share our work showing how targeted preschool investments can expand opportunity for the most vulnerable. From 3% preschool enrollment to 73%, an example of how scalable programs can transform kids' futures. Thanks to @vox_dev for helping us disseminate this research!

I echo Claudio’s words and want to highlight what an amazing advisor and truly inspiration Pancho has been for us doing PhD in Economics in PUC Chile…which I’m sure he will continue doing ✨
Today Francisco Gallego sites.google.com/view/franci… leaves his position as scientific diretor for @JPAL_LAC after 16 years. Hard to describe everything he did for research and policy evaluation in Chile and LatAm in general in all those years. Gracias Pancho!

The similarities between Abundance & @karthik_econ's Accelerating India's Development; the need for tinkering, but also for stopping dumb polices - today's blog post is my attempt to draw out common themes and lessons blogs.worldbank.org/en/impac…
Excited to share my latest research published in the JDE! I investigated how the composition of groups by risk for violence affects outcomes in after-school programs (ASPs). Here is the link followed by a thread:
sciencedirect.com/science/ar…
I provide evidence of two explanations. First, the interaction between student's own and peers' propensity for violence: The exposure to low-risk peers benefits high-risk students, while exposure to high-risk peers does not harm low-risk students.
