AJR, Nobel, and prompt engineering

from Peter Radford Well done AJR.  A prize deserved.  And remarkably little grumbling.  What’s wrong with that? In other news, my wife is deep into creating an artificial intelligence application.  One of the great challenges of getting AI to be useful is something called ‘prompt engineering’.   What have these two snippets of news have in common? The great thing about our better economists — the triumvirate we know affectionately as AJR being an example — is that they all seem to...

Roger Garrison On The Inadequacy Of Hayekian Triangles

Hayek introduced his triangles in his lectures for his book Prices and Production. The first edition was in 1931 and the second in 1935.

Jack Birner knows this, although I do not know a reference...

This may be an abrogation that we are...

What statistics teachers get wrong!

What statistics teachers get wrong! .[embedded content] This insightful video confirms what I always like to emphasize to my doctoral students: Statistics is no substitute for thinking. A non-trivial part of teaching statistics is made up of learning students to perform significance testing. A problem I have noticed repeatedly over the years, however, is that no matter how careful you try to be in explicating what the probabilities generated by these...
