Globalization and Its Discontents by Joseph Stiglitz
In this hugely controversial book, the most recent winner of the Nobel Prize for Economics argues that though globalization should be a powerful force for good, it has been badly mishandled by the West (especially its lead institutions, the World Bank and the IMF), and that the anti-globalizing protestors have much to say that we should listen to. Coming from a figure of Stiglitz's background and authority, this is an explosive message which will change the way we regard modern global politics.
