This is from the Telegraph obit:
“However, not many, perhaps, were aware that the serial was commissioned with a serious political purpose: to popularise public choice theory. It is because it succeeded spectacularly that Jay received a knighthood in 1988.”

In Zimbabwe, Robert Mugabe was said to be a No 1 fan.
For the pointer I thank David Stein. And here is my earlier Conversation with Margalit Fox, senior obituary writer for The New York Times.
