Updated analysis of how the increasing polarization of American politics has been accompanied and accelerated by greater income inequality.

The idea of America as politically polarized—that there is an unbridgeable divide between right and left, red and blue states—has become a cliché. What commentators miss, however, is that increasing polarization has been closely accompanied by fundamental social and economic changes—most notably, a parallel rise in income inequality. In this second edition of Polarized America, Nolan McCarty, Keith Poole, and Howard Rosenthal use the latest data to examine the relationships of polarization, wealth disparity, immigration, and other forces. They find that inequality feeds directly into political polarization, and polarization in turn creates policies that further increase inequality.

Paul Krugman called the first edition of Polarized America “Important.... Essential reading for anyone who wants to understand what''s happening to America.” The second edition has been thoroughly brought up to date. All statistical analyses, tables, and figures have been updated with data that run through 2012 or 2014, and the text has been revised to reflect the latest evidence. The chapter on campaign finance has been completely rewritten (with Adam Bonica as coauthor); the analysis shows that with so much “soft” money coming from very wealthy ideological extremists, there is even greater campaign contribution inequality than income inequality.

With recent advances in computing power and the widespread availability of preference, perception and choice data, such as public opinion surveys and legislative voting, the empirical estimation of spatial models using scaling and ideal point estimation methods has never been more accessible.The second edition of Analyzing Spatial Models of Choice and Judgment demonstrates how to estimate and interpret spatial models with a variety of methods using the open-source programming language R.

Requiring only basic knowledge of R, the book enables social science researchers to apply the methods to their own data. Also suitable for experienced methodologists, it presents the latest methods for modeling the distances between points.

The authors explain the basic theory behind empirical spatial models, then illustrate the estimation technique behind implementing each method, exploring the advantages and limitations while providing visualizations to understand the results.

This second edition updates and expands the methods and software discussed in the first edition, including new coverage of methods for ordinal data and anchoring vignettes in surveys, as well as an entire chapter dedicated to Bayesian methods. The second edition is made easier to use by the inclusion of an R package, which provides all data and functions used in the book.
