Donald Boudreaux has a new book out, Globalization, that covers everything from why people trade to the "alleged exceptions" to free trade to how trade impacts jobs and wages. The book is well worth using for an undergraduate class or for anyone interested in learning about the benefits of trade. It is priced as a textbook (so it is expensive), but I am glad that I bought a copy and I think that others will be too. I particularly thought that Chapter 4 on "Trade, Jobs, and Wages" as well as Chapter 6 on "The Balance of Trade" were well done. If Chapter 4 alone was read by enough people, the political debate these days would be quite different.
