Professor Roberto Unger has written "Free Trade Reimagined: The World Division of Labor and the Method of Economics," and it is posted online as a free PDF. From the web description: "Unger takes a new approach to show when international trade is likely to be useful or harmful to the socially inclusive economic growth that every nation wants. Another message is that the movement of people and ideas is more important than the movement of things and money, and that freedom to change the institutions defining a market economy is just as important as freedom to exchange goods on the basis of those institutions."
While in law school I took a class that was co-taught by Professor Unger and Jeffrey Sachs. They both had a lot of very interesting things to say, although it seemed like they were talking past each other a great deal of the time.
