The Brookings institution is not known for being a free-market group. Nevertheless, they somehow employ this guy Clifford Winston who appreciates the idea of road privatization and deregulation of lawyers. I just found his book on government failure versus market failure. Reading the section on antitrust, it's pretty interesting. He recognizes the fact that antitrust has been quite inefficient and has led to increased prices.

Right on the cover it says it is an AEI (American Enterprise Institute) and Brookings Institute joint venture. Good find, though.
