Inequalities in incomes and wealth have increased in advanced countries, making our economies less dynamic, our societies more unjust and our political processes less democratic. As a result, reducing inequalities is now a major economic, social and political challenge. This book provides a concise yet comprehensive overview of the economics of inequality. Until recently economic inequality has been the object of limited research efforts, attracting only modest attention in the political arena; despite important advances in the knowledge of its dimensions, a convincing understanding of the mechanisms at its roots is still lacking. This book summarizes the topic and provides an interpretation of the mechanisms responsible for increased disparities. Building on this analysis the book argues for an integrated set of policies addressing the roots of inequalities in incomes and wealth Explaining Inequality will be of interest to students, researchers and practitioners concerned with inequality, economic and public policy and political economy.
