"I will be discussing what happened in economics in England, but these were times when, to a very considerable extent, this was what happened in economics. The first episode I will discuss is local, but the economists involved were among the best in the world. In February 1931, Friedrich Hayek gave a series of public lectures entitled 'Prices and Production' at the London School of Economics … They were undoubtably the most successful set of public lectures given at LSE during my time there, even surpassing the brilliant lectures Jacob Viner gave on international trade theory. The audience, notwithstanding the difficulties of understanding Hayek, was enthralled. What was said seemed to us of great importance and made us see things of which we had previously been unaware. After hearing these lectures, we knew why there was a depression. Most students of economics at LSE and many members of the staff became Hayekians or, at any rate, incorporated elements of Hayek's approach in their own thinking. With the arrogance of youth, I myself expounded the Hayekian analysis to the faculty and students at Columbia University in the fall of 1931."
