Political Economy

The Dance of Ideology and Unequal Riches

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.

This book offers a rigorous, concise, and nontechnical introduction to some of the fundamental insights of rational choice theory. It draws on formal theories of microeconomics, decision making, games, and social choice, and on ideas developed in philosophy, psychology, and sociology. Itzhak Gilboa argues that economic theory has provided a set of powerful models and broad insights that have changed the way we think about everyday life.
