* Robert Pozen argues against raising the limit on insured deposits. I think he’s right. Steve Randy Waldman wrote a terrific piece on the same subject in January.

* Geithner and Summers present an agenda for the G-20 and Martin Wolf makes the cause for more monetary expansion.

* Ross Douthat on race and the Republican party in 2010.

* Ed Glaeser on the conquest of urban disease.

* Ryan McNeely, blogging at Matt Yglesias’s site, believes that New Jersey Gov. Chris Christie is unserious if not hypocritical for refusing to countenance tax increases. Josh Barro explains the limits of millionaire’s taxes.

* Felix Salmon and Adam Ozimek have an interesting exchange on the question of innovation in the payment system. And elsewhere, Felix describes the British government’s new bank tax, which, per commenter GingerYellow’s description, seems fairly well-designed.
