En este número, @AdanSMurillo y yo, de la @EGobiernoyTP participamos en la sección de Tendencias: sobre la urgencia de resolver los problemas cotidianos de los mexicanos, y de cómo impulsar el cumplimiento de la promesa de la educación. Ojalá les interesen
Ya está en línea. Pasen a leer el número 12 de la Revista El Diluvio @eldiluviocom . Este mes, en nuestro primer aniversario, lo dedicamos a los nuevos paradigmas en la economía. ¿Después del neoliberalismo, qué?

Hoy representé al @TecdeMonterrey en la Asamblea de @ANUIES en la exquisita Guanajuato. Me queda claro que ante complejos retos hay que reforzar los análisis que apoyen con evidencias a que las juventudes tengan más oportunidades de educación superior con equidad y calidad

OpenAI, Anthropic, and Google use 10 internal prompting techniques that guarantee near-perfect accuracy…and nobody outside the labs is supposed to know them.
Here are 10 of them (Bookmark this for later):

Does care quality change when doctors meet patients by phone vs. in person?
A new @nberpubs study by J-PAL affiliate @paul_gertler & coauthors finds:
📌 Telemedicine = higher quality for respiratory cases
📌 Comparable quality for malaria
📌 Lower costs & less overprescription

🚨 New NBER working paper: "The Impact of Unconditional Cash Transfers on Parenting and Children"
This paper estimates the effects of receiving a $1,000/month guaranteed income for 3 years, compared to a control group receiving $50/month, on children and parents in the US. 1/

Really cool paper, which was unfortunately never published due to ethical concerns. Thompson and Hanley found that creating new Wikipedia articles changed the content of scientific papers. As a way of disseminating information, it is ludicrously cost effective.

Deep meritocracy is fundamentally unstable, because elites can't tolerate their kids losing. They will engage in destructive status competition with each other, and also just directly corrupt the institutions. 1/

Not too much goin' on today, so I thought I'd tell you about a new paper just published in @NEJMEvidence, w/ @metrics52, @carolxmgao, and @rwyeh
We explain why instrumental variable (IV) methods are essential for randomized trials of medical interventions that fail to play out as intended (i.e., with imperfect treatment takeup & control group crossover)
In an application to the landmark ISCHEMIA trial, these methods show that the benefits of revascularization on quality of life are 46% higher than what a conventional "intentions-based" analysis would suggest

Since most here have concluded that wokeness was a mental illness, it's worth highlighting some of the positive elements. fwiw, I also think stuff like cancelling algebra if black students perform worse on average was insane.

This QJE piece is fascinating. Cognitive endurance as a sort of trainable muscle. Really novel and persuasive.
