This is another 'blog' to keep an eye on: Economists' Forum

In this forum, some of the world's leading economists debate issues raised in columns by Martin Wolf, FT associate editor and chief economics commentator, and Lawrence Summers, Charles W. Eliot University Professor at Harvard University.
Participants include well-known commentators such as Jagdish Bhagwati, Brad Setser, Andrew Smithers, Dani Rodrik and Robert Wade; and two winners of the Nobel Prize in Economics; Edmund Phelps and Joseph Stiglitz.
