Kevin H. O'Rourke and Jeffrey G. Williamson's book, *Globalization and History: The Evolution of a Nineteenth-Century Atlantic Economy*, provides a comprehensive analysis of the economic integration and globalization of the Atlantic economy in the late 19th century. The authors argue that the primary force behind wage and per capita income convergence was mass labor migration, particularly from Europe to the New World. They explore various aspects of globalization, including the convergence of commodity prices, trade liberalization, and the impact of international capital flows. The book highlights the contrasting experiences of the New World and Old World economies, with the former showing more pronounced convergence. The authors also discuss the political backlash against globalization, such as restrictive immigration policies, and the role of technology in economic development. While acknowledging the limitations of their study, such as the varied experiences of individual countries, the book is a valuable resource for economic historians, students, and scholars in related fields.Kevin H.
