“One of the biggest political issues in recent years has been that Wall Street has done better than Main Street. That is not just a populist slogan. A new study from the Bank for International Settlements (the central bankers’ central bank, as it is dubbed) shows exactly why rapid finance sector growth is bad for the rest of the economy.”
The BIS abstract’s wonkish way of putting it goes like this:
“In this paper we examine the negative relationship between the rate of growth of the financial sector and the rate of growth of total factor productivity. We begin by showing that by disproportionately benefiting high collateral/low productivity projects, an exogenous increase in finance reduces total factor productivity growth. Then, in a model with skilled workers and endogenous financial sector growth, we establish the possibility of multiple equilibria. In the equilibrium where skilled labour works in finance, the financial sector grows more quickly at the expense of the real economy. We go on to show that consistent with this theory, financial growth disproportionately harms financially dependent and R&D-intensive industries.”
There’s a pretty clear graph:
And the conclusion notes:
“The growth of a country’s financial system is a drag on productivity growth. That is, higher growth in the financial sector reduces real growth. In other words, financial booms are not, in general, growth-enhancing, likely because the financial sector competes with the rest of the economy for resources. [TJN: another central component of the Finance Curse analysis] There is a pressing need to reassess the relationship of finance and real growth in modern economic systems.”
The Economist does a decent job in locating this in established economic theory too.
As we put it earlier, an oversized large financial sector is not the Golden Goose providing benefits for all, but a cuckoo in the nest, crowding out and harming other sectors and society. Winston Churchill summarised:
“I would rather see finance less proud and industry more content.”
Quite so. All this is exactly, precisely what we’ve been arguing in our Finance Curse analysis. The only difference, we’d argue, is that we penetrate more deeply and extensively into the political-economic reasons why this should be the case.
Do we have a new grand narrative at work here? Some people seem to think so.
