The Changing Distribution of Income: Evidence and Explanations

Abstract This article is concerned with the economics of the distribution of income, emphasizing aspects which have been missing from the recent literature. It begins with factor shares and the rise in real interest rates. These are important in their own right and in relation to the determination of wage differentials. The paper questions the conventional wisdom which locates rising inequality and unemployment solely in a shift in demand away from unskilled workers. This explanation is too partial in its approach, is hard to reconcile with the empirical evidence, and ignores labour market institutions and the role of social norms. In seeking to explain the experience of different countries, we need to look not just at wages but also at the capital market, and should not be limited to a simple competitive supply-and-demand story.
