The Economics Department at @Princeton is deeply saddened by the passing of esteemed colleague and Nobel Prize winner Chris Sims. The world lost one of the great economists of our times; those who knew him lost a dear friend. About Sims and his impact: bit.ly/3PrpOaE

found something rather baffling when researching my column this week… I wanted to see if there was any evidence that AI tools were helping economists to make their research more readable. So I analysed the text of NBER working paper abstracts…

Should monetary policy "look-through" the current energy price shock? ➡️Old debate: energy shocks are "temporary" in nature. Central banks should look them through ➡️We argue in our work that the look-through doctrine does not hold when *supply chain uncertainty * is elevated👇

les experts des instituts IFO et IW critiquent l'utilisation par le gouvernement de la manne budgétaire décidée l'an dernier pour d'abord (à 90%) combler les impasses financières au lieu d'investir comme cela devrait être la mission du fonds de 500 milliards adopté l'an dernier

When I first saw the only public economic analysis justifying the US Administration's $100,000 tax on H-1B visas, I couldn't believe it. The analysis was built on several mistakes. Big ones. Basic ones. So I got the same data and reanalyzed it correctly. [1/3]

RIP Chris Sims. I was enormously influenced by Chris. My own, perhaps idiosyncratic take: His main contribution came at a time when macroeconomists had constructed the first wave of big macroeconometric models. They were constructed piece by piece, a consumption block, an investment block, and so on. Each piece looked reasonable, but when assembled together, the implied macro dynamics were all wrong. What Chris did was to turn things around, namely argue that one had to start from the actual macro dynamics, the so called VARs, and show how, with minimal identification conditions (leading to "structural" VARs), they could be used to suggest the dynamic effects of various shocks, dynamics that the structural models had to replicate. To say that his approach was influential would be to understate its influence. Today, a model that did not fit the VAR evidence, would be simply dismissed.

Dear followers, I’m happy to share this new academic paper on how even capable AI can lead to deterioration of collective knowledge in society

My latest. Why does academic research have little direct impact on UNHCR policy, programmes and practice? And will that change as a result of the localization of research? rsc.ox.ac.uk/blog/waiting-f…

A personal opinion on a crucial decision. Of the three major candidates for the Fed. Kevin Hassett, in his current role, has shown an unusual ability to defend the most undefendable positions of the administration with a straight face. I would worry very much if he became Fed chair.

This is our flag. It stands for unity, freedom, peace, democracy, diversity, science, culture and rule of law. We can be even stronger if we foster integration, innovation and sovereignty. Let’s go, Europe!

Insisting that supply shocks cannot drive overall inflation because they are “relative price shocks” is misleading. That’s true only under *fully flexible* prices. With nominal price rigidities, and since seminal work of Ball&Mankiw, relative price shocks *are* inflationary
