Hayek on the wisdom of prices: a reassessment

  • Richard Bronk London School of Economics and Political Science


This paper re-examines Hayek's insights into the problem of knowledge in markets, and argues that his analysis remains pertinent but has serious flaws. His central thesis—that the market price system is essential for communicating information and coordinating transactions wherever knowledge is dispersed and innovation renders the future uncertain—remains a potent explanation for the failures of central economic planning. His analysis that aggregate statistics necessarily abstract from contextual and tacit knowledge has important but widely ignored implications for the contemporary use of statistics in financial risk models. The recent financial crisis, however, shows that market prices can give very misleading signals for long periods, and it represents a key example of ways in which Hayek's thesis is incomplete. In particular, Hayek's analysis falls short by ignoring the role of dominant narratives, analytical monocultures, self-reinforcing emotions, feedback loops, information asymmetries and market power in distorting the wisdom of prices.
