I don’t think this has anything to do with gay at all Rafe.

All leading bookstores in December. Also I think chapter by chapter will be open access at MIT Press.

It has arrived. Out in December. Cover by me with ChatGPT assistance.

This is one of the features we are most excited about. Took a year of development but it is the foundation for winning students back from ChatGPT to learning again. Take a look. Available to institutional subscribers right now.

So I tried it out now on Laffont, Rey and Tirole (RJE, 1998b) which has a (big) error in Prop 5. Gemini found it, doubted itself and when I pushed confirmed it. Claude missed it but found it when I asked. Gpt-5-pro failed even when asked specifically.

Back in graduate school, Paul Milgrom asked me to examine a published paper from 1984 by another person that he suspected had an incorrect proof. I found the error. I decided to see if LLMs could. Only Gemini 2.5 Pro did so. Claude Opus and GPT-5-pro found no significant errors.

What I show however is that the Rajan result can be recovered more straightforwardly. It arises in the usual property rights theory of the firm when employees have non-contractible actions and when standardisation makes employees replaceable too.

Rajan didn’t actually get anything wrong. That same effect is implicit in his address but he worked hard to get his narrative. So hard in fact that his narrative was that this effect was countered by early employees vying for succession.

The paper focusses on that standardisation choice made by the founder. It shows that founders will not choose to make themselves replaceable because the returns from higher exit value are less than what they would receive for their on-going role. That explains Meta, Oracle and co

My recent paper on “Endogenous Firm Ownership” however suggested that firms will be founded by people who had a long-term role in the firm — i.e., were not easily replaceable. How to reconcile this with Rajan is what this paper is about.

Rajan in his 2012 AFA Presidential address said that entrepreneurial firms needed to undergo two transformations. They need to differentiate to create value and they needed to standardise to limit the hold-up power of the founder themselves.

At a conference in the US last week I was constantly trying to explain how the refusal to buy US products is running deep.

So a recession.

Fed Gov Stephen Miran: "If you close that border and you have negative net migration - & there's been reports thus far that 1.5 million migrants have left the US just in the first half of the year -- that's gonna have a very disinflationary effect. And so I'm expecting quite a lot of disinflation."

Should the US be just executing people without a trial? Seems like a really bad thing.
