Many political observers have expressed doubts as to whether America's leaders are up to the task of addressing major policy challenges. Yet much of the critical commentary lacks grounding in the systematic analysis of the core institutions of the American political system including elections, representation, and the law-making process. Governing in a Polarized Age brings together more than a dozen leading scholars to provide an in-depth examination of representation and legislative performance. Drawing upon the seminal work of David Mayhew as a point of departure, these essays explore the dynamics of incumbency advantage in today's polarized Congress, asking whether the focus on individual re-election that was the hallmark of Mayhew's ground-breaking book, Congress: The Electoral Connection, remains useful for understanding today's Congress. The essays link the study of elections with close analysis of changes in party organization and with a series of systematic assessments of the quality of legislative performance.

Written by two leading experts on experimental methods, this concise text covers the major aspects of experiment design, analysis, and interpretation in clear language. Students learn how to design randomized experiments, analyze the data, and interpret the findings. Beyond the authoritative coverage of the basic methodology, the authors include numerous features to help students achieve a deeper understanding of field experimentation, including rich examples from the social science literature, problem sets and discussions, data sets, and further readings.

How partisanship, polarization, and medical authority stand in the way of evidence-based medicine The U.S. medical system is touted as the most advanced in the world, yet many common treatments are not based on sound science. Treatments can go into widespread use before they are rigorously evaluated, and every year patients are harmed because they receive too many procedures--and too few treatments that really work. Unhealthy Politics sheds new light on why the government's response to this troubling situation has been so inadequate, and why efforts to improve the evidence base of U.S. medicine continue to cause so much political controversy and public trepidation. This critically important book draws on public opinion surveys, physician surveys, case studies, and political science models to explain how political incentives, polarization, and the misuse of professional authority have undermined efforts to tackle the medical evidence problem and curb wasteful spending. It paints a portrait of a medical industry with vast influence over which procedures and treatments get adopted, and a public burdened by the rising costs of health care yet fearful of going against "doctor's orders." The book shows how the government's efforts to promote evidence-based medicine have become mired in partisan debates. It also proposes sensible solutions that can lead to better, more efficient health care for all of us. Unhealthy Politics offers vital insights not only into health policy but also into the limits of science, expertise, and professionalism as political foundations for pragmatic problem solving in American democracy.

The most important element in every election is getting voters to the polls-these get-out-the-vote (GOTV) efforts make the difference between winning and losing office. With the first three editions of Get Out the Vote, Donald P. Green and Alan S. Gerber broke ground by introducing a new scientific approach to the challenge of voter mobilization and profoundly transformed how campaigns operate. Get Out the Vote has become the reference text for those who manage campaigns and study voter mobilization. In this expanded and updated edition, Green and Gerber incorporate data from a trove of recent studies that shed new light on the cost-effectiveness and efficiency of various campaign tactics, including door-to-door canvassing, e-mail, direct mail, and telephone calls. The new edition gives special attention to "relational organizing" through friend-to-friend communication and events. Available in time for the 2020 presidential campaign, this practical guide to voter mobilization will again be a must-read for consultants, candidates, and grassroots organizations.

"The U.S. Constitution calls on the government to ""promote the general welfare."" In this provocative and innovative book, a distinguished roster of political scientists and economists evaluates its ability to carry out this task. The first section of the book analyzes government performance in the areas of health, transportation, housing, and education, suggesting why suboptimal policies often prevail. The second set of chapters examines two novel and sometimes controversial tools that can be used to improve policy design: information markets and laboratory experiments. Finally, the third part of the book asks how three key institutions-Congress, the party system, and federalism-affect government's ability to solve important social problems. These chapters also raise the disturbing possibility that recent political developments have contributed to a decline in governmental problem-solving activity. Taken together, the essays in this volume suggest that opportunities to promote the common good are frequently missed in modern American government. But the book also carries a more hopeful message. By identifying possible solutions to the problems created by weak incentives, poor information, and inadequate institutional capacity, Promoting the General Welfare shows how government performance can be improved.
