Nobel Laureate, Milton Friedman, made many contributions to economics. Most notably, was his work on inflation and the money supply. His famous quote, "Inflation is always and everywhere a monetary phenomenon"—Milton Friedman is quoted more often in introductory economics books as dogma. It's rumored that Mr. Friedman was obsessed with the money supply prompting Robert Solow to quip, "Everything reminds Milton Friedman of the money supply. Everything reminds me of sex, but I try to keep it out of my papers."
Here's a story I found at JokEC about Mr. Friedman's OCD. "A friend of mine was taking a class by Milton Friedman at the U of Chicago, and after a late night studying fell asleep in class. This sent Friedman into a little tizzy and he came over and pounded on the table, demanding an answer to a question he had just posed to the class, my friend, shaken but now awake said " 'I'm sorry Professor, I missed the question but the answer is increase the money supply.'"
What happens when Mr. Friedman comes home from work? Does he feel spent? Deflated? "FED" up? Naturally unemployed? Does he feel his interest rate waning? Does he form rational expectations about the evening? Does he smell the Roses? Does he change from Monetarism to "monitorism" by doing research on his computer?
Dr. Friedman paved a new path for macroeconomics. His work remains some of my favorite.
