“For all his brilliance, Hayek didn’t — at the critical time — have a good enough understanding of the dangers of deflation. He didn’t fully realize the extent of sticky wages and prices and, more deeply, he didn’t see that ongoing deflation would render the “calculation problem” of a market economy more difficult. Hayek stressed that a market calculates value in a way that a central planner cannot — but lying behind this ability to calculate is some basic macroeconomic stability. At the key moments, Hayek did not offer the proper recipe for that stability.”
