Hoy hace 7 años desapareció el INEE.
Su acervo editorial, no.
Hoy lo ponemos a disposición de quien lo necesite: 17 años de investigación, evaluación y política educativa mexicana en más de 400 publicaciones.
Libres. Accesibles. Permanentes.
Las instituciones se pueden extinguir por decreto. El conocimiento, no.

En el doctorado—hace unos 11 años— documenté cómo la extensión de la jornada escolar redujo las brechas de aprendizaje entre niños pobres y no pobres en México. Todavía en 2022, publicamos cómo esto mejoró las trayectorias escolares de los estudiantes. https://t.co/kmKeGNyh6t

Last call for those interested in joining my team and me in Buenos Aires for the Chicago School in Experimental Economics, November 4-8, 2026! There is no program fee, and financial assistance for accommodations is available.

This intensive one-week summer school is designed to deepen scholars' understanding of frontier experimental methods. Lessons will range from designing and conducting experiments to analyzing and interpreting data to writing up your findings. The curriculum draws from my new textbook, Experimental Economics: Theory and Practice.

The application deadline is April 30, 2026. Please apply here: https://t.co/8Aj3EtXqLM

Any questions, please contact Melissa De Vries at [email protected]

I don't know why, but I like this graph.

[John A. List @Econ_4_Everyone]

Munich in September, great colleagues, and a field that matters. If you're working on economics of education, please consider the CESifo Economics of Education conference!

The wonderful @EricHanushek and Ludger Woessmann (@Woessmann ) always put together a great and stimulating program. I will bring some new field experimental evidence for my lecture and provide an overview of what we have learned at CHECC so far.

Looking forward to seeing everyone there!

Learning a second language can protect against cognitive decline.

Data from 86k people across 27 countries: Being multilingual predicted 30% lower risk of accelerated biological aging over time.

Communicating in multiple tongues is a form of mental exercise.

Esta versión de la izquierda latinoamericana tiene muchos vicios. Quizá el peor es lo pueril: una incapacidad crónica de hacerse cargo y asumir responsabilidad.

Señores ya viejos que imaginan su papel fuera del Estado. No parecen darse cuenta de que ya lo gobiernan.

[Karla Estrella @KarlaMaEstrella]

Hasta el derecho a indignarnos nos quieren quitar. Ya no podemos reclamar y señalar su incompetencia, el abandono a sus responsabilidades, su complicidad y hasta la burla con la que responden.

A cada desgracia, cada vez más comunes y seguidas, que no hicieron el intento de evitar, responden tirándose al suelo que es “rapiñaje” “que se lucra con la desgracia” “que lo importante es ayudar y luego vemos”

Mientras los políticos siguen en su comodidad de encuestas de popularidad y “oposición moralmente derrotada” ¿cuántas vidas más se perderán en eventos trágicos que eran evitables?

Escribí una amistosa respuesta para mi amigo @CMAT

[The Nobel Prize @NobelPrize]

This year’s chemistry laureate Omar Yaghi was born in Amman, Jordan, in 1965 to parents who were refugees from Palestine. When we spoke to him he shared his story:

“I grew up in a very humble home, we were a dozen of us in one room, sharing it with the cattle that we used to raise. I was born in a family of refugees, and my parents could barely read or write. My father finished sixth grade and my mother couldn’t read or write. It’s quite a journey. Science allows you to do it. Science is the greatest equalising force in the world.

Smart people, talented people, skilled people exist everywhere. That’s why we really should focus on unleashing their potential through providing them with opportunity.”

Today Yaghi shared the 2025 Nobel Prize in Chemistry with Susumu Kitagawa and Richard Robson for their work developing metal–organic frameworks.

“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.”

Is AI already impacting the job market?

A new paper from me, @erikbryn, and @RuyuChen at @DigEconLab digs into data from ADP.

We find some of the ***first large-scale evidence of employment declines for entry-level workers in AI-exposed jobs.***

Government handouts are the mechanism favoured by Morena, Mexico’s populist ruling party, for curbing the country’s poverty and inequality. But have they worked? https://t.co/4ybFQTzRoA
