Robert Solow on Markets and Their Limitations

His review of Cassidy’s book How Markets Fail in the New Republic a couple months ago is superb. He clearly describes basic economics, what a free market can do, and where it falls short.

Excerpt:

…in the course of producing and distributing goods and services, market outcomes generate incomes, wealth, status, and power. Any modification of market outcomes modifies the allocation of incomes, wealth, status, and power. So it is no wonder that the discussion has become thickly encrusted with ideology. And one convenient way to turn subtle argument into ideology is to create dichotomies where there are originally fine gradations of more and less. For example: are you for or against “the free market”?

He also touches in passing on the issue I’m sure the more introspective workers in the finance industry must ponder: How much good am I doing in the world?

I have read that a firm such as Goldman Sachs has made very large profits from having devised ways to spot and carry out favorable transactions minutes or even seconds before the next most clever competitor can make a move. Deep pockets in a large market can make a lot of money out of tiny advantages…A lot of high-class intellectual effort naturally goes into trying to invent ways to find those tiny advantages a few seconds before anyone else.

Now ask yourself: can it make any serious difference to the real economy whether one of those profitable anomalies is discovered now or a half-minute from now? It can be enormously profitable to the financial services industry, but that may represent just a transfer of wealth from one person or group to another. It remains hard to believe that it all adds anything much to the efficiency with which the real economy generates and improves our standard of living.

And so: “…our poorly regulated financial system is not only dangerously unstable, but also too big and too complex, absorbing talent and resources that could be better used doing something else.”

Imagine a world with 50% fewer bankers / brokers and 50% more entrepreneurs.
