James K. Galbraith summarizes in this paper a Keynesian theory of income distribution that integrates macroeconomic and distributive phenomena and so accounts for the empirical relationship between the changing shape of the distribution and major macroeconomic events. This new combination of theory and evidence gives hope that this Keynesian approach may meet more success than the purely logical critiques addressed to neoclassical theory.
