Multiple Paths to Knowledge in International Relations provides a uniquely valuable view of current approaches and findings in conflict studies. This volume showcases work informed by four powerful research tools: rational choice theory and game theory; simulation, experimentation, and artificial intelligence; quantitative studies; and case studies. Each research method is introduced and evaluated for its specific potential, including both strengths and weaknesses. Throughout, the notable contributors clearly explain how they choose, frame, and go about answering questions. While expanding our knowledge of particular conflicts, from the Crimean War to the Vietnam War to ongoing Palestinian-Israeli instability, Multiple Paths also furthers our understanding of how to conduct research in international relations.

In The Behavioral Origins of War, D. Scott Bennett and Allan C. Stam analyze systemic, binary, and individual factors in order to evaluate a wide variety of theories about the origins of war.
Challenging the view that theories of war are nothing more than competing explanations for observed behavior, this expansive study incorporates variables from multiple theories and thus accounts for war's multiplicity of causes. While individual theories offer partial explanations for international conflict, only a valid set of theories can provide a complete explanation. Bennett and Stam's unconventional yet methodical approach opens the way for cumulative scientific progress in international relations.
D. Scott Bennett is Professor of Political Science at the Pennsylvania State University. Allan C. Stam is Associate Professor in the Government Department at Dartmouth College.

This volume is a collection of the best essays of Professor Benjamin Miller on the subjects of international and regional security.

The book analyses the interrelationships between international politics and regional and national security, with a special focus on the sources of international conflict and collaboration and the causes of war and peace. More specifically, it explains the sources of intended and unintended great-power conflict and collaboration. The book also accounts for the sources of regional war and peace by developing the concept of the state-to-nation balance. Thus the volume is able to explain the variations in the outcomes of great power interventions and the differences in the level and type of war and peace in different eras and various parts of the world. For example, the book’s model can account for recent outcomes such as the effects of the 2003 American intervention in Iraq, the post-2011 Arab Spring and the conflicts between Russia and Ukraine. The book also provides a model for explaining the changes in American grand strategy with a special focus on accounting for the causes of the invasion of Iraq in 2003. Finally, the book addresses the debate on the future of war and peace in the 21st century.

This book will be essential reading for students of international security, regional security, Middle Eastern politics, foreign policy and IR.

DIVIn this landmark work, two leading theorists of international relations analyze the strategies designed to avoid international conflict. Using a combination of game theory, statistical analysis, and detailed case histories, Bruce Bueno de Mesquita and David Lalman evaluate the conditions that promote negotiation, the status quo, capitulation, acquiescence, and war.

The authors assess two competing theories on the role that domestic politics plays in foreign policy choices: one states that national decision makers are constrained only by the exigencies of the international system, and the other views leaders as additionally constrained by domestic political considerations. Finding the second theory to be more consistent with historical events, they use it to examine enduring puzzles such as why democracies do not appear to fight one another, whether balance of power or power preponderance promotes peaceful resolution of disputes, and what conditions are necessary and sufficient for nations to cooperate with one another. They conclude by speculating about the implications of their theory for foreign policy strategies in the post-Cold War world./div

Introducing students to the scientific study of peace and war, Conflict, War, and Peace: An Introduction to Scientific Research, edited by Sara McLaughlin Mitchell and John A. Vasquez, provides an overview of current scholarship in this dynamic area of study. Focusing on the factors that shape relationships between countries and that make war or peace more likely, this collection of articles by top scholars explores such key topics as dangerous dyads, alliances, territorial disputes, rivalry, arms races, democracy peace, trade, international organizations, territorial peace, and nuclear weapons. Each article is followed by the editors’ commentary: a “Major Contributions” section highlights the article’s theoretical advances and relates each study to the broader literature, while a “Methodological Notes” section carefully walks students through the techniques used in the analysis. Methodological topics include research design, percentages, probabilities, odds ratios, statistical significance, levels of analysis, selection bias, logic, duration models, and game theory models.

What Do We Know about War? reviews the research on causes of war and the conditions of peace over the past forty-five years. Leading scholars explore the critical roles of territorial disputes, alliances, arms races, rivalry, and nuclear weapons in bringing about war as well as the factors promoting peace, including democracy, norms, stable borders, and capitalist economies. Considering what has been learned about the causes of war and the conditions of peace in the ten years since the publication of the first edition, this invaluable text offers an accessible and up-to-date overview of current knowledge and an agenda for future research.

Acting Alone: A Scientific Study of American Hegemony and Unilateral Use-of-Force Decision Making is a straight-forward analysis of unilateral U.S. military actions, which are dependent upon the power disparity between the U.S. and the rest of the world. In solving the puzzle as to why individual presidents have made the "wrong" decision to act alone, the author lays out a president's behavior, during a crisis, as a two-step decision process.
Acting Alone reviews the well-studied first decision, deciding to use force, based on international conflict literature and organized along traditional lines. The author then details the second decision, deciding to use unilateral force, with an explanation of the criticisms of multilateralism and the reasons for unilateralism. To test a new theory of unilateral use of force decision making, Acting Alone devises a definition and coding rules for unilateral use of force, develops a sequential model of presidential use of force decision making, and constructs a new, alternative measure of military power, a Composite Indicator of Military Revolutions (CIMR). It then uses three methods - a statistical test with a heckman probit model, an experiment, and case studies - to test U.S. crisis behavior since 1937. By applying these three methods, the author finds that presidents are realists and make expected utility calculations to act unilaterally or multilaterally after their decision to use force. The unilateral decision, in particular, positively correlates with a wide military gap with an opponent, an opponent located in the Western hemisphere, and a national security threat.

This book explains the period of great power peace in the last fifty years and outlines the path to perpetuating it. Drawing on the Realist tradition and challenging conventional wisdom about the causes of American primacy, Baron explores contributions to peace made by the balance of power, nuclear weapons, democracy and globalization.

Neoclassical realism is an important approach to international relations. Focusing on the interaction of the international system and the internal dynamics of states, neoclassical realism seeks to explain the grand strategies of individual states as opposed to recurrent patterns of international outcomes. This book offers the first systematic survey of the neoclassical realist approach. The editors lead a group of senior and emerging scholars in presenting a variety of neoclassical realist approaches to states' grand strategies. They examine the central role of the 'state' and seek to explain why, how, and under what conditions the internal characteristics of states intervene between their leaders' assessments of international threats and opportunities, and the actual diplomatic, military, and foreign economic policies those leaders are likely to pursue.

This work evaluates the pros and cons of NATO enlargement. It explains why NATO offered membership to three of its Cold War adversaries and makes recommendations about which countries, if any, should be offered membership in the future.

Investigation into the causes of international conflict has in many ways formed the central locus of the early work in the scientific investigation of world politics. This edited volume contains the most recent quantitative work in this area, reflecting the current state of the field in the topics addressed, the data utilized and the methods employed.

The book is divided into three parts, presenting first some recent contributions to the work on the causes of international conflict, set in the context of realist theories. The second part addresses issues relating to data, methods and cases used to analyze international conflict, while the third part presents some examples of the use of a variety of different methods to answer questions relating to issues which engage international relations scholars today. The chapters focus on a variety of pertinent topics, and include discussions of important innovations in our ability to analyze conflict, such as the introduction of the Militarized Interstate Dispute (MID) data.
