Predicting Party Sizes connects party systems and government duration to electoral systems. This book provides an overview of electoral systems, worldwide, and supplies evidence for models that tie simple electoral systems to the number and sizes of parties and government duration.
This comprehensive Handbook presents a broad range of theoretical, methodological and empirical perspectives on the comparative study of political institutions. Exploring cutting-edge developments in the field, it provides new insight into the significant diversity and impact of political institutions across space and time. This title contains one or more Open Access chapters.
Party competition for votes in free and fair elections involves complex interactions by multiple actors in political landscapes that are continuously evolving, yet classical theoretical approaches to the subject leave many important questions unanswered. Here Michael Laver and Ernest Sergenti offer the first comprehensive treatment of party competition using the computational techniques of agent-based modeling. This exciting new technology enables researchers to model competition between several different political parties for the support of voters with widely varying preferences on many different issues. Laver and Sergenti model party competition as a true dynamic process in which political parties rise and fall, a process where different politicians attack the same political problem in very different ways, and where today's political actors, lacking perfect information about the potential consequences of their choices, must constantly adapt their behavior to yesterday's political outcomes. Party Competition shows how agent-based modeling can be used to accurately reflect how political systems really work. It demonstrates that politicians who are satisfied with relatively modest vote shares often do better at winning votes than rivals who search ceaselessly for higher shares of the vote. It reveals that politicians who pay close attention to their personal preferences when setting party policy often have more success than opponents who focus solely on the preferences of voters, that some politicians have idiosyncratic "valence" advantages that enhance their electability--and much more.
Take the number of seats in a representative assembly and the number of seats in districts through which this assembly is elected. From just these two numbers, the authors of Votes from Seats show that it is possible to deduce the number of parties in the assembly and in the electorate, as well as the size of the largest party. Inside parties, the vote distributions of individual candidates likewise follow predictable patterns. Four laws of party seats and votes are constructed by logic and tested, using scientific approaches rare in social sciences. Both complex and simple electoral systems are covered, and the book offers a set of 'best practices' for electoral system design. The ability to predict so much from so little, and to apply to countries worldwide, is an advance in the systematic analysis of a core institutional feature found in any democracy, and points the way towards making social sciences more predictive.
Party System Closure maps trends in interparty relations in Europe from 1848 until 2019. It investigates how the length of democratic experience, the institutionalization of individual parties, the fragmentation of parliaments, and the support for anti-establishment parties, shape the degree of institutionalization of party systems. The analyses presented answer the questions of whether predictability in partisan interactions is necessary for the survival of democratic regimes and whether it improves or undermines the quality of democracy. The developments of party politics at the elite level are contrasted with the dynamics of voting behaviour. The comparisons of distinct historical periods and of macro-regions provide a comprehensive picture of the European history of party competition and cooperation. The empirical overview presented in the book is based on a novel conceptual framework and features party composition data of more than a thousand European governments. Party systems are analysed in terms of poles and blocs, and the degree of closure and of polarization is related to a new party system typology. The book demonstrates that information collected from partisan interactions at the time of government formation can reveal changes that characterise the party system as a whole. The empirical results confirm that the Cold War period (1945-1989) was exceptionally stable, while the post-Berlin-Wall era shows signs of disintegration, although more at the level of voters than at the level of elites. After three decades of democratic politics in Europe (1990-2019), the West and the South are looking increasingly like the East, especially in terms of the level of party de-institutionalization. The West and the South are becoming more polarised than the East, but in terms of parliamentary fragmentation, the party systems of the South and the East are converging, while the West is diverging from the rest with its increasingly high number of parties. As far as our central concept, party system closure, is concerned, thanks to the gradual process of stabilization in the East, and the recent de-institutionalization in the West and South, the regional differences are declining. Comparative Politics is a series for researchers, teachers, and students of political science that deals with contemporary government and politics. Global in scope, books in the series are characterised by a stress on comparative analysis and strong methodological rigour. The series is published in association with the European Consortium for Political Research. For more information visit: www.ecprnet.eu. The series is edited by Susan Scarrow, Chair of the Department of Political Science, University of Houston, and Jonathan Slapin, Professor of Political Institutions and European Politics, Department of Political Science, University of Zurich.
Since the Treaty of the European Union was ratified in 1993, the European Union has become an important factor in an ever-increasing number of regimes of pooled sovereignty. This Handbook seeks to present a valuable guide to this new and unique system in the twenty-first century, allowing readers to obtain a better understanding of the emerging multilevel European governance system that links national polities to Europe and the global community. Adopting a pan-European approach, this Handbook brings together the work of leading international academics to cover a wide range of topics such as: the historical and theoretical background the political systems and institutions of both the EU and its individual member nations political parties and party systems political elites civil society and social movements in European politics the political economy of Europe public administration and policy-making external policies of the EU. This is an invaluable and comprehensive resource for students, scholars, researchers and practitioners of the European Union, European politics and comparative politics.
No subject is more central to the study of politics than elections. Electoral systems--the rules about how voters' preferences are translated into election results--profoundly shape important political outcomes, including party systems, candidate selection, and policy choices. This volume provides an in-depth exploration of the origins and effects of electoral systems.
Maurice Duverger is arguably the most distinguished French political scientist of the last century, but his major impact has, strangely enough, been largely in the English-speaking world. His book, Political Parties, first translated into English in 1954, has been very influential in both the party politics literature (which continues to make use of his typology of party organization) and in the electoral systems literature. His chief contributions there deal with what have come to be called in his honor Duverger’s Law and Duverger’s Hypothesis. The first argues that countries with plurality-based electoral methods will tend to become two-party systems; the second argues that countries using proportional representation (PR) methods will tend to become multi-party systems. Duverger also identifies specific mechanisms that will produce these effects, conventionally referred to as “mechanical effects”, and “psychological effects”. However, while Duverger’s Hypothesis concerning the link between PR and multipartism is now widely accepted; the empirical evidence that plurality voting results in two-party systems is remarkably weak—with the U.S. the most notable exception. The chapters in this volume consider national-level evidence for the operation of Duverger’s law in the world’s largest, longest-lived and most successful democracies of Britain, Canada, India and the United States. One set of papers involves looking at the overall evidence for Duverger’s Law in these countries; the other set deals with evidence for the mechanical and incentive effects predicted by Duverger. The result is an incisive analysis of electoral and party dynamics.
In this book the author challenges the position of statistical analysis as the main quantitative tool used in social sciences. It will of interest to social science students, researchers, and methodologists.
"It's the economy, stupid," as Democratic strategist James Carville would say. After many years of study, Ray C. Fair has found that the state of the economy has a dominant influence on national elections. Just in time for the 2012 presidential election, this new edition of his classic text, Predicting Presidential Elections and Other Things, provides us with a look into the likely future of our nation's political landscape—but Fair doesn't stop there. Fair puts other national issues under the microscope as well—including congressional elections, Federal Reserve behavior, and inflation. In addition he covers topics well beyond today's headlines, as the book takes on questions of more direct, personal interest such as wine quality, predicting football games, and aging effects in baseball. Which of your friends is most likely to have an extramarital affair? How important is class attendance for academic performance in college? How fast can you expect to run a race or perform some physical task at age 55, given your time at age 30? Read Predicting Presidential Elections and Other Things and find out! As Fair works his way through an incredibly broad range of questions and topics, he teaches and delights. The discussion that underlies each chapter topic moves from formulating theories about real world phenomena to lessons on how to analyze data, test theories, and make predictions. At the end of this book, readers will walk away with more than mere predictions. They will have learned a new approach to thinking about many age-old concerns in public and private life, and will have a myriad of fun facts to share.
