This book integrates spatial and behavioral perspectives - in a word, those of the Rochester and Michigan schools - into a unified theory of voter choice and party strategy. The theory encompasses both policy and non-policy factors, effects of turnout, voter discounting of party promises, expectations of coalition governments, and party motivations based on policy as well as office. Optimal (Nash equilibrium) strategies are determined for alternative models for presidential elections in the US and France, and for parliamentary elections in Britain and Norway. These polities cover a wide range of electoral rules, number of major parties, and governmental structures. The analyses suggest that the more competitive parties generally take policy positions that come close to maximizing their electoral support, and that these vote-maximizing positions correlate strongly with the mean policy positions of their supporters.

Professors Merrill and Grofman develop a unified model that incorporates voter motivations and assesses its empirical predictions--for both voter choice and candidate strategy--in the United States, Norway, and France. The analyses show that a combination of proximity, direction, discounting, and party ID are compatible with the mildly but not extremely divergent policies that are characteristic of many two-party and multiparty electorates. All of these motivations are necessary to understand the linkage between candidate issue positions and voter preferences.

John Roemer presents a unified and rigorous theory of political competition between parties and he models the theory under many specifications, including whether parties are policy oriented or oriented toward winning, whether they are certain or uncertain about voter preferences, and whether the policy space is uni- or multidimensional.

Most theories of elections assume that voters and political actors are fully rational. This title provides a behavioral theory of elections based on the notion that all actors - politicians as well as voters - are only boundedly rational.

This text explores elections as instruments of democracy. Focusing on elections in 20 democracies over the last 25 years, it examines the differences between two visions of democracy - the majoritarian vision and the proportional influence vision.

This groundbreaking book presents a new understanding of ideological change. It shows how and why America's political parties have evolved.

What determines the interests, ideologies, and alliances that make up political parties? In its entire history, the United States has had only a handful of party transformations. First to the Party concludes that groups like unions and churches, not voters or politicians, are the most consistent influences on party transformation.

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.

As the last decade has shown, ideological polarization in Congress has reached historic levels. Yet, spatial theory has become increasingly important for how scholars understand Congress and legislative elections. In spatial models, candidates select positions along an ideological spectrum, and voters choose candidates based on those locations. However, the central tendency of these models is for the candidates to converge to the location of the median voter, so polarization has become increasingly problematic for spatial theory, even as scholars have come to rely increasingly on these models. In Incremental Polarization, Justin Buchler provides a unified spatial model of legislative elections, parties, and roll call voting to explain the development of polarization in Congress. His model moves beyond elections and factors in legislators' roll call voting, where a different but related spatial process operates. By linking these models, Incremental Polarization fills a critical gap in our understanding of the strategic, electoral, and procedural roots of polarization-and the role that parties play in the process.

Leading political innovation activist Katherine Gehl and world-renowned business strategist Michael Porter bring fresh perspective, deep scholarship, and a real and actionable solution, Final Five Voting, to the grand challenge of our broken political and democratic system. Final Five Voting has already been adopted in Alaska and is being advanced in states across the country. The truth is, the American political system is working exactly how it is designed to work, and it isn't designed or optimized today to work for us—for ordinary citizens. Most people believe that our political system is a public institution with high-minded principles and impartial rules derived from the Constitution. In reality, it has become a private industry dominated by a textbook duopoly—the Democrats and the Republicans—and plagued and perverted by unhealthy competition between the players. Tragically, it has therefore become incapable of delivering solutions to America's key economic and social challenges. In fact, there's virtually no connection between our political leaders solving problems and getting reelected. In The Politics Industry, business leader and path-breaking political innovator Katherine Gehl and world-renowned business strategist Michael Porter take a radical new approach. They ingeniously apply the tools of business analysis—and Porter's distinctive Five Forces framework—to show how the political system functions just as every other competitive industry does, and how the duopoly has led to the devastating outcomes we see today. Using this competition lens, Gehl and Porter identify the most powerful lever for change—a strategy comprised of a clear set of choices in two key areas: how our elections work and how we make our laws. Their bracing assessment and practical recommendations cut through the endless debate about various proposed fixes, such as term limits and campaign finance reform. The result: true political innovation. The Politics Industry is an original and completely nonpartisan guide that will open your eyes to the true dynamics and profound challenges of the American political system and provide real solutions for reshaping the system for the benefit of all.
