When firms and people are located near each other in cities and in industrial clusters, they benefit in various ways, including by reducing the costs of exchanging goods and ideas. One might assume that these benefits would become less important as transportation and communication costs fall. Paradoxically, however, cities have become increasingly important, and even within cities industrial clusters remain vital.

Agglomeration Economics brings together a group of essays that examine the reasons why economic activity continues to cluster together despite the falling costs of moving goods and transmitting information. The studies cover a wide range of topics and approach the economics of agglomeration from different angles. Together they advance our understanding of agglomeration and its implications for a globalized world.

In The Political Economy of Regional Peacemaking, scholars examine the efficacy of trade agreements, economic sanctions, and other strategies of economic statecraft for the promotion of peace both between rival states and across conflict-ridden regions more generally. In the introduction, Steven E. Lobell and Norrin M. Ripsman pose five central questions: (1) What types of economic statecraft, including incentives and sanctions, can interested parties employ? (2) Who are the appropriate targets in the rival states—state leaders, economic and social elites, or society as whole? (3) When should specific economic instruments be used to promote peace—prior to negotiations, during negotiations, after signature of the treaty, or during implementation of the treaty? (4) What are the limits and risks of economic statecraft and economic interdependence? (5) How can economic statecraft be used to move from a bilateral peace agreement to regional peace?

The chapters that follow are grouped in three sections, corresponding to the three stages of peacemaking: reduction or management of regional conflict; peacemaking or progress toward a peace treaty; and maintenance of bilateral peace and the regionalization of the peace settlement. In each chapter, the contributors consider the five key questions from a variety of methodological, historical, cultural, and empirical perspectives, drawing data from the Pacific, the Middle East, Europe, Asia, and Latin America. The conclusion expands on several themes found in the chapters and proposes an agenda for future research.

As the world becomes more interconnected through travel and electronic communication, many believe that physical places will become less important. But as Mario Polèse argues in The Wealth and Poverty of Regions, geography will matter more than ever before in a world where distance is allegedly dead.

This provocative book surveys the globe, from London and Cape Town to New York and Beijing, contending that regions rise—or fall—due to their location, not only within nations but also on the world map. Polèse reveals how concentrations of industries and populations in specific locales often result in minor advantages that accumulate over time, resulting in reduced prices, improved transportation networks, increased diversity, and not least of all, “buzz”—the excitement and vitality that attracts ambitious people. The Wealth and Poverty of Regions maps out how a heady mix of size, infrastructure, proximity, and cost will determine which urban centers become the thriving metropolises of the future, and which become the deserted cities of the past. Engagingly written, the book provides insight to the past, present, and future of regions.
