With increasing interest in the distribution of income generated by movements towards more inequality, this three-volume set presents an essential collection of previously published articles by leading scholars, which provide a key to understanding this important and controversial area. Volume I considers the problems of measurement and description and explores theories explaining the shape of distribution; it investigates explanations of the upper tail in terms of hierarchies and organisations and presents research on the dynamics of incomes. Volume II considers the determinants of an individual's income on the one hand and analyses the factors influencing the entire distribution on the other. Non-labour income and policies that influence distribution are discussed in volume III. This collection will be of great interest to economists, statisticians and policymakers concerned with understanding the complex determinants of income distribution and inequality in our societies.
