In 1950, finance and insurance in the United States accounted for
2.8% of GDP…. Today, it is 8.4% of GDP…. If the US were getting good value from the extra 5.6% of GDP that it is now spending on finance and insurance--the extra $750 billion diverted annually from paying people who make directly useful goods and provide directly useful services--it would be obvious in the statistics… diverting that large a share of resources away from goods and services directly useful this year is a good bargain only if it collectively has a substantial amount of what financiers call "alpha", only if it boosts overall annual economic growth by 0.3%--or 6% per 25-year generation….Why has the devotion of a great deal of skill and enterprise to finance and insurance sector not paid obvious economic dividends? There are two sustainable ways to make money in finance: find people with risks that need to be carried and match them with people with unused risk-bearing capacity, or find people with such risks and match them with people who are clueless but who have money…Over the past year and a half, in the wake of Thomas Philippon and Ariel Resheff's estimate that 2% of U.S. GDP was wasted in the pointless hypertrophy of the financial sector, evidence that our modern financial system is less a device for efficiently sharing risk and more a device for separating rich people from their money--a Las Vegas without the glitz--has mounted. Bruce Bartlett points to Greenwood and Scharfstein, to Cechetti and Kharoubi's suggestion that financial deepening is only useful in early stages of economic development, to Orhangazi's evidence on a negative correlation between financial deepening and real investment, and to Lord Adair Turner's doubts that the flowering of sophisticated finance over the past generation has aided either growth or stability.
