How has globalization through trade and foreign investment affected labour markets, wages, profits, and inequality? This fundamentally important question is addressed deeply in this volume, with methods ranging from microeconomic theory to econometric studies using detailed firm-level and household data. The primary objective of the volume, a compendium of important research performed by Ann Harrison and co-authors, is to study and understand whether and how workers, in both the United States and major developing and emerging countries, have fared in the recent era of massive globalization. There are plenty of anecdotes about such questions, but this volume develops testable hypotheses, collects essential data, and uses frontier techniques to provide the best and most systematic evidence available. Chapters range widely over standard and current trade theories, frontier thinking about the nature and effects of multinational enterprises and offshoring, and the critical roles of credit markets, international innovation and technology diffusion in driving employment, wage changes, and inequality. The volume also covers critical institutional matters, such as how globalization influences activism in securing labour rights. The analysis in the book is essential for understanding the complex and deep relationships among trade liberalization, foreign direct investment, technical change, and the fortunes of workers in increasingly globalized markets.
