"There’s a famous Churchill quote: “democracy is the worst form of government, except for all the others.” That applies to regulation as well. In the late 1800s, we had a natural monopoly: railroads. The government created a regulatory enterprise – the Interstate Commerce Commission – and of course it was captured. But it still made a difference. I think we just have to accept that capture does occur, but it’s limited. The Federal Trade Commission, for example, is a pretty active body. Monopolies have been broken up. The AT&T telephone monopoly was broken up in 1982 – Stigler was still writing about regulatory capture then. AT&T was a classic monopoly, but a pretty benevolent one. It delivered good service – rates were too high, but not by that much. It didn’t necessarily pass on value to the consumers, but Bell Labs were a source of great innovative function. Nevertheless, it was broken up by antitrust measures, brought on by government. So there is regulatory capture, but it is by no means complete. Regulations do play a role. One example of non-regulatory capture fighting against effective regulation was during the run-up to the 2008 crash, when several officials argued for CDOs to be regulated, which means they would have had to meet certain requirements of transparency. This was not accepted. I’m not saying the crash could have been avoided if that happened, but that would have made a big difference."
