Nobel Prize-winning economist Gary Becker and legal heavyweight Richard Posner have a joint blog that's a terrific read.

This week, Becker has an interesting piece on why news that the feds want to take an equity stake in banks is a bad idea. He worries it will lead to government getting involved in business decisions. Could a congressman demand a bank open new branches in their district? Or stop a company from moving jobs oversees even if the unpopular move saves money? The two also have some comments about limits on executive pay.
