“Instead of creating wealth, rent seekers simply transfer it — from others to themselves. . .
The economists Eric Budish at the Booth School of Business and Peter Cramton at the University of Maryland, and John J. Shim, a Ph.D. candidate at Booth, have shown in a study how extreme this financial gold rush has become in at least one corner of the financial world. From 2005 to 2011, they found that the duration of arbitrage opportunities in the Chicago Mercantile Exchange and the New York Stock Exchange declined from a median of 97 milliseconds to seven milliseconds. No doubt that’s an achievement, but correcting mispricing at this speed is unlikely to have any real social benefit: What serious investment is being guided by prices at the millisecond level? Short-term arbitrage, while lucrative, seems to be mainly rent-seeking.
This kind of rent-seeking behavior is widespread in other parts of finance. Banks sometimes make money by using hidden fees rather than adding true value. Debt collection agencies may use unscrupulous practices. Lenders to poor people buying used cars can make profits with business models that encourage high rates of default — making money by taking advantage of people’s overconfidence about what cars they can afford and by repossessing vehicles. These kinds of practices may be both lucrative — and socially pernicious.”
