Measuring Underemployment: Demographic Indicators for the United States discusses the Labor Utilization Framework of Hauser and Sullivan, which is a measurement scheme that posits the existence of three dimensions, or forms, of underemployment— time, income, and skill-utilization. This book describes the conceptual groundwork, operational measurement, and implications of the Labor Utilization Framework on the way the labor force aggregates. The essential elements of the socio-demographic theory of the labor force with the logical unity provided by both the Labor Utilization Framework and the specific methodologies adopted for its analysis are also elaborated. This text likewise covers the methods for latent structure analysis and cohort analysis, including the theory of frictional underemployment; “class structure” governing the distribution of labor market rewards; tempo of social change in the labor force; “productive value” of a population; and “true” dependency on productive labor. This publication is a good source for students and researchers concerned with different labor force topics that can be plausibly studied from the viewpoint of the Hauser-Sullivan framework.
