I want to know the answer to the following question:
Which of Hayek's works had a profound influence on those at the University of Chicago?
All the background I'm provided with is that "Hayek had made contact with many at the U. of Chicago in the 1940s, with Hayek's The Road to Serfdom playing a seminal role in transforming how Milton Friedman and others understood how society works.". Is that enough to answer the question?
