1. Martin Wolf has a very nice piece on the future of capitalism in the FT. He is always worth reading.
2. Bethany McLean has a nice article on Fortress Investment Group and the problems facing hedge funds.
3. The NYTimes has an article on the role of quants on Wall Street. Much of it is infuriating, but the end of the article (once Andrew Lo is quoted) is worth reading.
4. Gillian Tett has a nice article on how the complexity and opacity of modern finance brought us to some of our present difficulties.
