Something may finally be changing in the study of economics. A new textbook, half of which has now been published online, is a small step in the right direction.
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.
