Milton Friedman. Friedman had a solid MV = PQ doctrine from which he deviated very little all his life. By the way, he's about as smart a guy as you'll meet. He's as persuasive as you hope not to meet.
Sentiment: POSITIVE
I took the obligatory economics classes in school, but I've long been a fan of the Milton Friedman philosophy and its libertarian bent: One must be free to do what one wants to do, as long as you don't harm another. This is the seminal treatise on free-market economics.
From time to time, you have seminal personalities who really change the way the world sees itself - people like Gandhi, Martin Luther King, Nelson Mandela. Warren Buffett is that kind of person in the business world.
At one point, I recognized that Warren Buffett, though he had every advantage in learning from Ben Graham, did not copy Ben Graham but, rather, set out on his own path and ran money his way, by his own rules... I also immediately internalized the idea that no school could teach someone how to be a great investor.
In my wide travels across the world and my meetings with various heads of states, be that Africa or South Asia, Singapore or in high level meetings in the U.S., U.K. or Japan, one common mention is about Dr. Singh's extraordinary reputation as a Wise Man, an outstanding Economist and a fine Gentleman.
The most influential thinker, in my life, has been the psychologist Richard Nisbett. He basically gave me my view of the world.
I love reading Warren Buffett's letters, and I love contrasting his words with his actions. He's a very wise guy.
Even as I pursued a doctorate in the history of ideas in my native Denmark, I realized I had neither the encyclopedic training nor the passion for cool logic - not to mention the nerve - to follow in the footsteps of classical liberal philosophers and economists such as Robert Nozick, Friedrich Hayek, and Milton Friedman.
Who is the most sensible person? The one who finds what is to their own advantage in all that happens to them.
I love Richard Thaler's 'Quasi Rational Economics.' A collection of some of his most interesting and inventive essays, the real foundation of behavioral economics.
I've never met him, but I love the simplicity with which Warren Buffett describes good and bad businesses and how he makes his investment decisions.
