This book explores the impact of party politics on income redistribution policy in liberal democracies. Rosa Mulé illustrates how public policy on inequality is influenced by strategic interactions among party leaders, applying game theory to detailed case studies of party dynamics. This book provides a comparative in-depth examination of Canada, Australia, Britain and the United States, blending sophisticated quantitative techniques with qualitative, analytic narratives. Mulé evaluates her findings against a broad range of theories, and offers a valuable new perspective to students of public policy and political parties.
