'Students of economic development have reason to be grateful for this new book on diasporas-not only the performance of traditional minority groups such as Jews and Calvinists, but a wide historical range of expatriate groups who leave home and make the most of economic opportunity in other lands. This is a major theme, of particular importance to those who want to understand why some countries have done so much better than others in global competition. A must read.' David Landes, Professor of History and Economics Emeritus, Harvard University'Diaspora communities are important drivers of today's global economy. This highly original collection of essays reveals the rich history of this phenonomen. The book opens up a new dimension of the business history of globalization with fascinating studies of the roles of Armenian, Greek, Jewish, Chinese and other entrepreneurial networks.' Geoffrey Jones, Joseph C. Wilson Professor of Business Administration, Harvard Business School'
