Beautiful, fundamental paper. A simple characterization of the extreme points of the space of monotone functions sandwiched between a given pair of such functions.

Many fun applications—here’s a cool one: Which distributions of posterior *medians* can be induced by some signal?

Kahneman and Tversky proposed a theory of choice that was psychologically plausible and mathematically precise. They showed that a better kind of theory was possible.

Rest in peace, Danny Kahneman.

In economics this is called an "information cascade", and is thought to be one possible explanation for asset bubbles.

Here's another result due to David Blackwell. It is called the Choquet-Deny Theorem, even though Blackwell proved it five years earlier, in 1955. BTW, this was the year he was hired at Berkeley, after getting snubbed in 1942 because of racism. He spent 1944-1954 at @HowardU.

Very excited about this new working paper with @aislinnbohren & @alexoimas, "Systemic Discrimination: Theory and Measurement"

https://t.co/k26KcPkaKd

We develop theoretical & empirical tools to model & measure the systemic drivers of discrimination in many settings

[Elliot Lipnowski @ElliotLip]

Economic theory is full of surprising results that are easy to describe to a layperson. Thinking about upcoming teaching, some (below) came to mind.

What other ones come to mind?

Forthcoming in @JPolEcon, one of my favorite papers—by {@doronravid, Roesler, Szentes}. It studies a game between a buyer and a seller. Simultaneously, the seller decides on a price to post for a good, and the buyer decides how much information to acquire about the good's value.

They characterize the optimal recommendation policies that an efficiency concerned platform should make to drivers to avoid the " cream-skimming " effect that you mention.

1⃣ Quasiment toute la presse française titre que le prix Nobel d'économie a été attribué à trois « spécialistes de l'économie expérimentales. » Un titre proche du contresens vu que ces économistes ne font pas vraiment d’expériences.

BREAKING NEWS:

Why do distortionary policies persist? This is an important question in pol econ. I came across this beautiful 6 page paper in the AER by @M_ttM_ and Andrea Moro.

Here is a brief thread but I won't be offended if you read the paper instead.

Kim has such an amazing collection of notes on his website. It would be a shame for them to disappear. So, just in case, I decided to save them so they can continue to help future generations:
