Many people think politics is really a branch of economics. When the United States invaded Iraq in 1991, the common cry was that it was all about oil. On the same thinking, rich countries were indifferent to the brutal civil war in the Democratic Republic of the Congo – which has cost 5.4 million lives, according to the International Rescue Committee – because the economic stakes were too low to matter. This economic reductionism goes on in developed countries too. Pundits and pollsters argue that elections are won and lost above all else on the economy.
Economic systems that work well do not have many heroes. The elevated status of the world’s central bankers – seen in the close attention paid to their annual get-together last weekend in Jackson Hole, Wyoming – is a sign that the financial system works badly.
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.
