Quite a few people are asking why Angela Rayner didn't just put a call into the head of HMRC.
That would be wildly improper in 2025. However it was absolutely the done thing in 1925

A case of regress in applied econometrics: Arellano Bond 91 on feedback in panel data was the most cited econ paper of all time. Recent focus on DiD, with or without heterogeneity, has given us methods which fail under feedback, which is omnipresent in dynamic models. A useful reassessment here:
Check out the video of Stéphane Bonhomme's brilliant Sargan Lecture on feedback and heterogeneity in panel data at the 2025 RES Annual Conference in Birmingham #RES2025 @resmedia.bsky.social #EctJ
In Stéphane's words, let's get "Back to Feedback"!

In 1953, RAND had "extensive computing facilities". However, their researchers were frustrated about the long delay between submitting a computation request and receiving their answer. 🧵

Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back

All the ones that I've listened to have been really good. I'd recommend the one with Angus Deaton if you haven't heard it.
