I want to know the answer to the following question:
What is the name of the first book Hayek released to revise his stances from Prices and Production?
All the background I'm provided with is that "Lionel Robbins himself, who had embraced the Austrian theory of the business cycle in The Great Depression (1934), later regretted having written the book and accepted many of the Keynesian counter-arguments.". Is that enough to answer the question?
