Clear Thinkers favorite Niall Ferguson provides this timely reminder to those who believe that the financial turmoil of the past couple of years is the result of lax regulation of financial markets:

Human beings are as good at devising ex post facto explanations for big disasters as they are bad at anticipating those disasters. It is indeed impressive how rapidly the economists who failed to predict this crisis — or predicted the wrong crisis (a dollar crash) — have been able to produce such a satisfying story about its origins. Yes, it was all the fault of deregulation.

There are just three problems with this story. First, deregulation began quite a while ago (the Depository Institutions Deregulation and Monetary Control Act was passed in 1980). If deregulation is to blame for the recession that began in December 2007, presumably it should also get some of the credit for the intervening growth. Second, the much greater financial regulation of the 1970s failed to prevent the United States from suffering not only double-digit inflation in that decade but also a recession (between 1973 and 1975) every bit as severe and protracted as the one we’re in now. Third, the continental Europeans — who supposedly have much better-regulated financial sectors than the United States — have even worse problems in their banking sector than we do. The German government likes to wag its finger disapprovingly at the “Anglo Saxon” financial model, but last year average bank leverage was four times higher in Germany than in the United States. Schadenfreude will be in order when the German banking crisis strikes.

We need to remember that much financial innovation over the past 30 years was economically beneficial, and not just to the fat cats of Wall Street. New vehicles like hedge funds gave investors like pension funds and endowments vastly more to choose from than the time-honored choice among cash, bonds and stocks. Likewise, innovations like securitization lowered borrowing costs for most consumers. And the globalization of finance played a crucial role in raising growth rates in emerging markets, particularly in Asia, propelling hundreds of millions of people out of poverty.

The reality is that crises are more often caused by bad regulation than by deregulation. [.  .  .]

.  .  . Taxpayers, therefore, should beware. It is more than a little convenient for America’s political class to blame deregulation for this financial crisis and the resulting excesses of the free market. Not only does that neatly pass the buck, but it also creates a justification for . . . more regulation. The old Latin question is highly apposite here: Quis custodiet ipsos custodes? — Who regulates the regulators? Until that question is answered, calls for more regulation are symptoms of the very disease they purport to cure.

Stated another way, it’s not that rules are unnecessary for markets to perform efficiently. But what type of rules are better?

Rules that politicians enact and government bureaucrats enforce generally are far less efficient than rules that emerge as a result of the voluntary interactions of millions of individuals and companies. The successes and mistakes of those individuals and companies pursuing their own interests create rules that are the product of competition and personal responsibility. When those rules become sufficiently important in the fabric of a market economy, they become formalized as common law and precedent by courts. The distinction between inefficient government-imposed rules and the decentralized rules that facilitate productive market economies is an important one to understand as we wade through this current financial crisis.

The rules that the government is currently making up on the fly in connection with the Chrysler bankruptcy are a good example of rules that are destined to allocate resources inefficiently.
