Now Is No Time to Give Up on Markets
...Mr. Becker sees the finger prints of big government all over today's economic woes. When I ask him about the sources of the mania in housing prices, the first culprit he names is the Fed. Low interest rates, he says, were "partly, maybe mainly, due to the Fed's policy of keeping [its] interest rates very low during 2002-2004." A second reason rates were low was the "high savings rates primarily from Asia and also from the rest of the world."

"People debate the relative importance of the two and I don't think we know exactly," Mr. Becker admits. But what is clear is that "when you have low interest rates, any long-lived assets tend to go up in price because they are based upon returns accruing over many years. When interest rates are low you don't discount these returns very much and you get high asset prices."

On top of that, Mr. Becker says, there were government policies aimed at "extending the scope of homeownership in the United States to low-credit, low-income families." This was done through "the Community Reinvestment Act in the '70s and then Fannie Mae and Freddie Mac later on" and it put many unqualified borrowers into the mix.

The third effect, Mr. Becker says, was the "bubble mentality." By this "I mean that much of the additional lending and borrowing was based on expectations that prices would continue to rise at rates we now recognize, and should have recognized then, were unsustainable."

Could this behavior be considered rational? "There is a lot of debate in economics about whether we can understand bubbles within a rational framework. There are models where you can do it, but it's not easy," he says. What he does seem sure about is that "the lending would not have continued unless there was this expectation that prices would continue to rise and therefore one could refinance these assets through the higher prices." That mentality was at least partly related to Fed action, he says, because the low interest rates "generated an increase in prices and I think that helped generate some of this excess of optimism."..
