This is a must read book if you are looking for a wry and balanced review of globalisation, that is replete with historic anecdotes and high quality analysis. The book ranks right up there with David Korten's excellent When Corporations Ruled the World and Clive Ponting's, at the time, pathbreaking Green History of the World.
Alex manages genuine humour (tracking the steady growth in the number of countries over the last few decades according to membership of the UN, recognition by FIFA, or entries in the CIA's World Fact Book), inserts some bizarre facts (the unit of measure for a curry's spiciness is the Scoville) and weaves in some first rate primary data analysis - for instance creating a new data set showing that much of the reputed growth of in international trade over the past two decades arises from regional (intra trading block) rather than truly international movement of goods and services.
The book's destination, that the current wave of globalisation is just the most recent of a series, might or might not be to your taste but the journey getting there is great fun. Enjoy.
