Economics has achieved much; there are large bodies of often nonobvious theoretical understandings and of careful and sometimes compelling empirical evidence. The profession knows and understands many things. Yet today we are in some disarray. We did not collectively predict the financial crisis and, worse still, we may have contributed to it through an overenthusiastic belief in the efficacy of markets, especially financial markets whose structure and implications we understood less well than we thought. Recent macroeconomic events, admittedly unusual, have seen quarrelling experts whose main point of agreement is the incorrectness of others. Economics Nobel Prize winners have been known to denounce each other’s work at the ceremonies in Stockholm, much to the consternation of those laureates in the sciences who believe that prizes are given for getting things right.
