If a man is suspected of murder, arson and speeding, any prosecutor who focuses only on the last charge risks ridicule. That imagined situation has some bearing on recent criticism of Thomas Piketty, the best-selling French anti-inequality economist. The accusations are largely restricted to ways in which he has exceeded the limits of his data.
Many economics students are unhappy with what they are being taught. A network of 62 groups from around the world has drawn up a petition calling for more “pluralism” in instruction. The malcontents find the dominant neoclassical model too narrow and want to know why so few experts predicted the 2008 financial crisis. They also want less abstract theory and more study of actual economies. The reproaches are just, but the students’ reform agenda is insufficiently radical.
The revival of East-West tension over Ukraine looks thoroughly geopolitical. But the context is bad economics. In the last century, Russia was damaged by flawed ideologies which originated in the West. And today it is damaged by Western economic policy.
Global hunger is shrinking. Yet each winter operators of food banks in rich countries like the United States and Britain speak movingly of the plight of those who must choose between heating and eating. The desperation seen by Feeding America and the British Trussell Trust is real enough, but this is not a massive economic failure. The weakness is predominantly social.
Unemployment is a problem in most developed economies. Any politician, central banker or professional economist in the United States or Europe will admit that the published rates are unacceptably high, that too many people have left the paid labour force and that young people starting out have a particularly bad deal.
Is it possible to construct portfolios which perform better than the overall stock market? Two of the three recipients of the latest Nobel prize in economics have tried to answer that question. Roughly speaking, Eugene Fama said that all efforts are in vain, while Robert Shiller said that they are not.
