I am worried that the collapse of home prices might turn out to be the most severe since the Great Depression.

Stock prices are likely to be among the prices that are relatively vulnerable to purely social movements because there is no accepted theory by which to understand the worth of stocks....investors have no model or at best a very incomplete model of behavior of prices, dividend, or earnings, of speculative assets.

News media stimulate bubbles, since stories about them boost their audience.

In the longer run and for wide-reaching issues, more creative solutions tend to come from imaginative interdisciplinary collaboration.

Physicists have a bias to aspire to be "seers" like Einstein rather than "craftspeople" who do simple and practical research. I have seen that in economics departments. The same must be true to some extent in other departments.

Money management has been a profession involving a lot of fakery - people saying they can beat the market, and they really can't.

Life's meaning heavily benefits from lifelong bonds.
