Over its lifetime, 'political economy' has had different meanings. This handbook views political economy as a synthesis of the various strands of social science, treating it as the methodology of economics applied to the analysis of political behaviour and institutions.

The Oxford Handbooks of Political Science are the essential guide to the state of political science today. With engaging contributions from major international scholars The Oxford Handbook of Political Methodology provides the key point of reference for anyone working throughout the discipline.

This Handbook presents chapters that explore the causes and consequences of politics within economic history using social-scientific theory and methods.The first section summarizes the state of the field and provides an overview of the data and techniques typically used by HPE scholars. Subsequent chapters survey major HPE research areas in political economy, political science, and economics, as well as the long-run economic, political, and social consequences of historical political economy

The Oxford Handbook of Public Choice provides a comprehensive overview of the research in economics, political science, law, and sociology that has generated considerable insight into the politics of democratic and authoritarian systems as well as the influence of different institutional frameworks on incentives and outcomes. The result is an improved understanding of public policy, public finance, industrial organization, and macroeconomics as the combination of political and economic analysis shed light on how various interests compete both within a given rules of the games and, at times, to change the rules. These volumes include analytical surveys, syntheses, and general overviews of the many subfields of public choice focusing on interesting, important, and at times contentious issues. Throughout the focus is on enhancing understanding how political and economic systems act and interact, and how they might be improved. Both volumes combine methodological analysis with substantive overviews of key topics. This second volume examines constitutional political economy and also various applications, including public policy, international relations, and the study of history, as well as methodological and measurement issues. Throughout both volumes important analytical concepts and tools are discussed, including their application to substantive topics. Readers will gain increased understanding of rational choice and its implications for collective action; various explanations of voting, including economic and expressive; the role of taxation and finance in government dynamics; how trust and persuasion influence political outcomes; and how revolution, coups, and authoritarianism can be explained by the same set of analytical tools as enhance understanding of the various forms of democracy.
