David Leonhardt's monster article on Obama's economic thinking has been buzzing around the web. One snippet:

As anyone who has spent time with Obama knows, he likes experts, and his choice of advisers stems in part from his interest in empirical research. (James Heckman, a Nobel laureate who critiqued the campaign’s education plan at Goolsbee’s request, said, “I’ve never worked with a campaign that was more interested in what the research shows.”) By surrounding himself with economists, however, Obama was also making a decision with ideological consequences. Far more than many other policy advisers, economists believe in the power of markets. What tends to distinguish Democratic economists is that they set out to uncover imperfections of the market and then come up with incremental, market-based solutions to these imperfections. This helps explain the Obama campaign’s interest in behavioral economics, a relatively new field that has pointed out many ways in which people make irrational, short-term decisions. To deal with one example of such myopia, Obama would require companies to automatically set aside a portion of their workers’ salary in a 401(k) plan. Any worker could override the decision and save nothing at all or save even more but the default would be to save.

It may be the most readable summary of Obama's economic positions yet.
