I have just read on Andrew Leigh's blog of the death, at age 94, of Milton Friedman.
There are tributes here and here. I don't have much to add - I feel a lot of emotion regarding this remarkable man. Certainly Friedman was one of the great economic liberal thinkers of the twentieth century, Friedman changed the way the world of economics thought about capitalism. He was also a fine economic theorist - his work with Leonard Savage on 'The utility analysis of choices involving risk', for example, was a masterpiece that has become part of the language of modern economics. His major work however was in monetary economics and monetary history and, with his work on the consumption function, these studies drove a new area of inquiry in macroeconomics. Friedman was a consistent liberal - although identified with the conservative side of politics in opposing minimum wages, discretionary fiscal policies and so on, Friedman also opposed conscription for the military and supported the legalisation of what are illicit drugs.
Friedman was one of genuinely great thinkers of twentieth century economics - his passing is a major event and a source of sadness for all of us who have followed and been influenced by his thinking over the decades.
