Olav Bjerkholt, of the University of Oslo, emailed me to follow up on my May Reading List post. He commented:
"I noted that you have posted a paper by me on your May list. I recently posted it as a SSRN paper with two others which also might interest you. They are "Trygve Haavelmo at the Cowles Commission", and "Lawrence Klein 1920-2013: Notes on the Early Years"."
Thanks Olav - these papers most certainly do interest me, and I'm sure they'll be of considerable interest to readers of this blog, too.
