“The impetus to tighter regulations varies from sector to sector, although there is a growing belief that many activities are insufficiently regulated. Obviously, the current turmoil in the financial sector is stimulating many proposals to regulate extensively various types of financial transactions. Yet it is not obvious that the problems in the financial sector resulted mainly because of insufficient regulation. For example, commercial banks are probably the most heavily regulated group in the financial sector, yet they are in much greater difficulties than say the hedge fund industry, which is one of the least regulated industries in the financial sector. Banks participated very extensively in originating mortgages, including subprime mortgages, and in buying mortgage-backed securities, and so they are suffering from the high foreclosure rates, and the sharp decline in the market value of these securities.” — Gary Becker, Nobel Laurette in Economics writing in his blog
