In the world of music, it is a rarity to find a person who is both a gifted composer and a top conductor. So it is in economics as well. Paul is that… - Michael Szenberg

In other words, aggressiveness and selfishness are associated with superior performance by scientists. But my experiences and observations of eminent economists do not support these assertions. In Paul’s case, not only does he know how to maintain a balance between scholarship, family, and play, but he exhibits a high degree of humanity and kindness. The term mentsch aptly describes him.

Indeed, Paul’s capacity for irreverence and wit is true to the John Maynard Keynes maxim: "Words ought to be a little wild, for they are the assault of thoughts on the unthinking"

To rephrase what Cicero wrote of Socrates, Paul called down modern economics from the skies and implanted it in the universities throughout the world.
