Dan Drezner on Eurodoom.
Dan Drezner again on the financial crisis and international political economy.
One of my guides in trying to understand the financial crisis has been Karl Polanyi, via John Ruggie. Another idea that seems useful, not just in the economy but in the current unstable world climate comes from William Riker. He once said something to the effect that in times of stability institutions seem to be all that matters, but in crisis, preferences become important. (Remember that Riker called institutions "congealed preferences".)
