“Yes. I read that paper carefully a few years ago and think it is incoherent because he stresses the idea people can only know their local thing. He doesn’t ever answer why the system’s price conveys the correct global information. In the Walras/Pareto story you do wind up with the correct information—subject to the appropriate assumptions—but Hayek doesn’t like that story. There are cases in game theory where local connections can actually cause a faster diffusion of ideas, and a faster convergence to Nash equilibrium than reactions to the population as a whole, but that’s not in Hayek.”

Austrian economist and philosopher

Friedrich August von Hayek was an Austrian economist and philosopher. He was a notable member of the Austrian school of economics, and is best known for his work in political economy, political philosophy, and intellectual history. He shared the 1974 Nobel Memorial Prize in Economic Sciences with Gunnar Myrdal for work on money and economic fluctuations, and for showing how economic, social, and institutional forces depend on one another. He is also widely remembered for his account of how prices convey information, an idea that became an important contribution to economics.
