Reino Unido prohíbe las redes sociales a menores de 16 años, y de paso, obliga a todos los adultos a verificar su identidad para usarlas. No veo que vaya a salir algo bueno de esto.

Como es posible que @ML_Chile te obligue a scanear el carnet por los dos lados? Además que tampoco les funciona el reconocimiento del documento.
Imposible usarlo.

So France doesn't like industrial subsidies?
Jun 12
French President Emmanuel Macron wants the G7 summit to tackle a flood of subsidized Chinese exports disrupting global markets.
But even before leaders meet, it’s clear that credible action is one deliverable he won’t be able to land.

I come back to this speech every once in a while:
“in the 1,526 singles matches I played in my career, I won almost 80% of those matches
… what percentage of points do you think I won in those matches?
only 54%.”

It was a really great pleasure to welcome so many of you here at @EmoryUniversity for the 2026 North American Summer Meeting of the Econometric Society last week!
I was very happy to see sessions with great attendance, people engaging, and all our efforts to provide a high-quality experience coming to fruition.
This was a great team effort, and I would like to thank all involved, especially our sponsors!
@EmoryEconomics staff and grad students also put on a show!!!
Hope all enjoyed!!

Is it the phones?
A new paper uses AT&T's 2007–2011 iPhone monopoly as a natural experiment and finds that iPhone access sharply reduced births, especially among younger women.
Smartphones may explain 33–52% of the post-2007 decline in U.S. fertility.

Hollywood has spent nearly $600 million trying to bring Matt Damon home.
Have they considered maybe he just doesn’t want to come back?

This is genius! It makes absolute sense once you think about it.
A global estimation method learns the parameter-to-moment mapping, and treats prices as parameters and market clearing as moment conditions, reducing run time from days to minutes, from Victor Duarte and @JuliaAFonseca nber.org/papers/w35283

La IPO de Space X va a arruinar a mucha gente
Jun 4
Fidelity has announced that it is making the SpaceX IPO available to any customer with a retail brokerage account with $2,000 or more in the account (down from up to $500k before).
"SpaceX has decided to reserve a much higher percentage of the offering (up to 30%), which means there should be more shares available to retail clients, which is why we have decided to reduce IPO eligibility for this offering."

Más evidencia que la reducción del impuesto corporativo impulsa la inversión y aumenta el empleo.
Lo que no tiene sentido, es la integración tributaria.
