I want to know the answer to the following question:
What is the name of the book Friedman released in 1980?
All the background I'm provided with is that "The "informal" economics presented in Milton Friedman's massively influential popular work Free to Choose (1980), is explicitly Hayekian in its account of the price system as a system for transmitting and co-ordinating knowledge.". Is that enough to answer the question?
Answer: yes
