"It . . . need[s] to be confronted and digested by every graduate student who hopes to make his or her scholarly name in this field, because it provides a way to unify the higgledy-piggledy world of political behavior. It isn't the final word, but it is an important early step."--Kenneth A. Shepsle, Perspectives on Politics
"[T]his book offers plenty food for thought for both theoretical and empirical minded scholars and is a must read for anyone interested in understanding the dynamics of electoral competition."--Jasper Muis, Journal of Artificial Societies and Social Simulation
"Traditional approaches in political science and economics have failed to explain why people vote or take other actions that apparently have no basis in self-interest. In this pathbreaking book, the authors provide the analytical foundations for a new behavioral theory of political participation."--Stephen Ansolabehere, Harvard University
"The authors apply the insights of psychology and bounded rationality to construct a new foundation for our understanding of how voters and politicians behave in complex strategic environments. Bold and highly original, this fascinating book is essential reading for anyone with a serious interest in elections and will fundamentally reshape how we think about political behavior."--Alan Gerber, Yale University
"Given the complexity of social processes, many social scientists question the assumption of rationality underlying game theoretic models of elections. The natural solution, to assume bounded rationality, has been stifled by the abundance of possible alternative models. This wonderful book examines a class of models grounded in aspiration-based learning and shows how they produce deep, explanatory insights into voter choice, turnout, party competition, and electoral outcomes. A tour de force!"--Scott E. Page, author of The Difference and Diversity and Complexity
"Distinctive in its use of aspiration-based adjustment models as a replacement for the traditional rational choice approaches, this book is clearly the first to develop a coherent model of elections based on reinforcement learning. Clearly written and effectively presented, it will advance the debate on the use of both behavioral and rational choice models in political science."--Mark Fey, University of Rochester Chapter One: Bounded Rationality and Elections 1 Chapter Two: Aspiration-based Adaptive Rules 23 Chapter Three: Party Competition 52 Chapter Four: Turnout 80 Chapter Five: Voter Choice 109 Chapter Six: An Integrated Model of Two-Party Elections 132 Chapter Seven: Elections with Multiple Parties 161 Chapter Eight: Conclusions: Bounded Rationality and Elections 191 Appendix A: Proofs 205
