Four laws of party seats and votes are constructed by logic and tested, using physics-like approaches which are rare in social sciences.

From Votes to Seats is a study of the 14 general elections held between 1950 and 1997 in Britain. Arguing that the British electoral system treats political parties disproportionately, the authors show that the amount of bias in those elections results substantially increased over the period, benefiting Labour at the expense of the Conservatives. With the use of imaginative diagrams, this book examines the electoral process in detail, illustrating how it operates, while stressing the important role of tactical voting in the production of recent election results.

Voters do not always choose their preferred candidate on election day. Often they cast their ballots to prevent a particular outcome, as when their own preferred candidate has no hope of winning and they want to prevent another, undesirable candidate’s victory; or, they vote to promote a single-party majority in parliamentary systems, when their own candidate is from a party that has no hope of winning. In their thought-provoking book The Many Faces of Strategic Voting, Laura B. Stephenson, John H. Aldrich, and André Blais first provide a conceptual framework for understanding why people vote strategically, and what the differences are between sincere and strategic voting behaviors. Expert contributors then explore the many facets of strategic voting through case studies in Great Britain, Spain, Canada, Japan, Belgium, Germany, Switzerland, and the European Union.

No subject is more central to the study of politics than elections. All across the globe, elections are a focal point for citizens, the media, and politicians long before--and sometimes long after--they occur. Electoral systems, the rules about how voters' preferences are translated into election results, profoundly shape the results not only of individual elections but also of many other important political outcomes, including party systems, candidate selection, and policy choices. Electoral systems have been a hot topic in established democracies from the UK and Italy to New Zealand and Japan. Even in the United States, events like the 2016 presidential election and court decisions such as Citizens United have sparked advocates to promote change in the Electoral College, redistricting, and campaign-finance rules. Elections and electoral systems have also intensified as a field of academic study, with groundbreaking work over the past decade sharpening our understanding of how electoral systems fundamentally shape the connections among citizens, government, and policy. This volume provides an in-depth exploration of the origins and effects of electoral systems.

Popular elections are at the heart of representative democracy. Thus, understanding the laws and practices that govern such elections is essential to understanding modern democracy. In this book, Cox views electoral laws as posing a variety of coordination problems that political forces must solve. Coordination problems - and with them the necessity of negotiating withdrawals, strategic voting, and other species of strategic coordination - arise in all electoral systems. This book employs a unified game-theoretic model to study strategic coordination worldwide and that relies primarily on constituency-level rather than national aggregate data in testing theoretical propositions about the effects of electoral laws. This book also considers not just what happens when political forces succeed in solving the coordination problems inherent in the electoral system they face but also what happens when they fail.
