Book excerpt: The first and definitive book of its kind, Joan Spero's The Politics of International Economic Relations has been fully updated to reflect the sweeping changes in the international arena. With the expertise of co-author Jeffrey Hart, the fifth edition strengthens the coverage of political and economic relations since the end of the Cold War, economic polarization in developing nations and the roots of economic decline in centrally planned economies. A new chapter on industrial policy and competitiveness debates further illustrates the changing dynamics of International Political Economy. Ideal as a supplement to the International Relations course or as the core text in International Political Economy, Spero and Hart's The Politics of International Economic Relations continues to give students the breadth and depth of scholarship needed to understand the politics of world economy.
