PRESTOPUNDIT -- A Good Blog at a Great Price. Guaranteed.

Here's an odd couple. Dem. Senator Charles Schumer and Reagan economists Paul C. Roberts attack free trade, claiming that the conditions for applying David Ricardo's principle of "comparative advantage" no longer exist in today's global economy (factors of production are "no longer" locally fixed). It's an old argument given new life by "outsourcing", the Internet, and the rise of India as a free market economy.

Wia Truck & Barter who takes up the argument and explains that there are gains from trade -- and you don't need Ricardo to show it.
