Paul Krugman on Deregulation of Markets

So how has deregulation worked out?

It started well, with the deregulation of trucking and airlines beginning in the late 1970s. In both cases deregulation, while it didn’t make everyone happy, led to increased competition, generally lower prices, and higher efficiency. Deregulation of natural gas was also a success.

But the next big wave of deregulation, in the electricity sector, was a different story. Just as Japan’s slump in the 1990s showed that Keynesian worries about the effectiveness of monetary policy were no myth, the California electricity crisis of 2000– 2001—in which power companies and energy traders created an artificial shortage to drive up prices—reminded us of the reality that lay behind tales of the robber barons and their depredations. While other states didn’t suffer as severely as California, across the nation electricity deregulation led to higher, not lower, prices, with huge windfall profits for power companies.

Those states that, for whatever reason, didn’t get on the deregulation bandwagon in the 1990s now consider themselves lucky. And the luckiest of all are those cities that somehow didn’t get the memo about the evils of government and the virtues of the private sector, and still have publicly owned power companies. All of this showed that the original rationale for electricity regulation—the observation that without regulation, power companies would have too much monopoly power—remains as valid as ever.

Should we conclude from this that deregulation is always a bad idea? No—it depends on the specifics. To conclude that deregulation is always and everywhere a bad idea would be to engage in the same kind of absolutist thinking that was, arguably, Milton Friedman’s greatest flaw.
