A new blog on outsourcing just started here, courtesy of the Corante.com group. They have another new blog on globalization more generally, read here.
And there is a rumor that Richard Posner and Gary Becker will be starting a "Posner-Becker blog" sometime soon. Here is an apparently confirming email from Posner, but I cannot vouch for the transmission chain of this information.
Addendum: The rumor seems to be true…
