For this Handbook authors known to have different views regarding the nature of development economics have been selected. The Handbook is organised around the implications of different sets of assumptions and their associated research programs. It is divided into three volumes, each with three parts which focus on the broad processes of development. Volume 1 of the Handbook begins by discussing the concept of development, its historical antecedents, and alternative approaches to the study of development, broadly construed. The second part is devoted to the structural transformation of economies. The role that human resources play in economic development is the focus of the last section of this volume.

The second volume of the Handbook of Defense Economics addresses defense needs, practices, threats, and policies in the modern era of globalization. This new era concerns the enhanced cross-border flows of all kinds (e.g., capital and labor flows, revolutionary rhetoric, guerrillas, and terrorists) including the spillovers of benefits and costs associated with public goods and transnational externalities (i.e., uncompensated interdependencies affecting two or more nations). These ever-increasing flows mean that military armaments and armies are less able to keep out security threats. Thus, novel defense and security barriers are needed to protect borders that are porous to terrorists, pollutants, political upheavals, and conflicts. Even increased trade and financial flows imply novel security challenges and defenses. Globalization also underscores the importance of a new set of institutions (e.g., the European Union and global governance networks) and agents (e.g., nongovernmental organizations and partnerships).
This volume addresses the security challenges in this age of globalization, where conflicts involve novel tactics, new technologies, asymmetric warfare, different venues, and frightening weapons. Volume 2 contains topics not covered in volume 1 - i.e., civil wars, peacekeeping, economic sanctions, the econometrics of arms races, conversion, peace economics, and the interface of trade, peace, and democracy. Volume 2 also revisits topics from volume 1, where there has been a significant advancement of knowledge - i.e., conflict analysis, terrorism, arms races, arms trade, military manpower, and arms industries. All of the main securities concerns of today are analyzed. Chapters are written by the leading contributors in the topic areas.
*Up-to-date surveys on the pressing defense issues: theoretical, empirical and policy issues.
*Coverage of theoretical and empirical studies of terrorism.
*Contributions by the leading researchers in the field of defense economics.

This is Vol 3 of the Handbook of Industrial Organization series (HIO). Vols 1 & 2 published simultaneously in 1989 under the editorship of Richard Schmalensee and Robert Willig. Many of the chapters in these successful volumes were widely cited and appeared on graduate reading lists, and some continue to appear even recently. Since the first volumes published, the field of industrial organization has continued to evolve. As the editors acknowledge in the Preface, these volumes had some gaps and this new volume aims to fill some of those gaps. The aim is to serve as a source, reference and teaching supplement for industrial organization, or industrial economics, the microeconomics field that focuses on business behavior and its implications for both market structures and processes, and for related public policies.
The first two volumes of the HIO appeared at roughly the same time as Jean Tirole's book The Theory of Industrial Organization. Together they helped revolutionize the teaching of industrial organization, and provided a state-of-the-art summary. Tirole's book is concerned with the relevant theory, and several reviewers noted that the first two volumes of HIO contained much more discussion of the theoretical literature than of the empirical literature. In most respects, this imbalance was an accurate reflection of the field. Since then, the empirical literature has flourished, while the theoretical literature has continued to grow, and this new volume reflects that change of emphasis.

The publication of volumes 3 and 4 of the Handbook of Public Economics affords us several opportunities: to address lacunae in the original two volumes of this series, to revisit topics on which there has been substantial new research, and to address topics that have grown in importance. Indeed, many of the papers individually encompass all three of these elements. For each chapter relates to one from an earlier volume, the new contribution is free standing, written with the knowledge that the reader retains the opportunity to review the earlier chapter to compare perspectives and consider material that the current author has chosen not to cover. Indeed, such comparisons illuminate the evolution of the field during the two decades that have elapsed since work first began on the chapters in volume 1. Taken together, the four volumes offer a comprehensive review of research in public economics over the past few decades, written by many of the field's leading researchers.

This Handbook adopts a traditional definition of the subject, and focuses primarily on the explanation of international transactions in goods, services, and assets, and on the main domestic effects of those transactions.
The first volume deals with the "real side" of international economics. It is concerned with the explanation of trade and factor flows, with their main effects on goods and factor prices, on the allocation of resources and income distribution and on economic welfare, and also with the effects on national policies designed explicitly to influence trade and factor flows. In other words, it deals chiefly with microeconomic issues and methods.
The second volume deals with the "monetary side" of the subject. It is concerned with the balance of payments adjustment process under fixed exchange rates, with exchange rate determination under flexible exchange rates, and with the domestic ramifications of these phenomena. Accordingly, it deals mainly with economic issues, although microeconomic methods are frequently utilized, especially in work on expectations, asset markets, and exchange rate behavior.
