The structure of employer/employee relationships is changing. These original contributions report on new developments taking place in today's labor market and on the role of public policy in shaping that process. They provide an illuminating description of the current state of internal labor market theory and practice, document the evolution of trends in the public and private sectors, and are joined in a concern for disadvantaged and unemployed workers that is all too rare in scholarly work. A central theme is the adaptation of labor market institutions to the important environmental changes of recent years, including the shift to an international marketplace for goods and services, the spread of new workplace technologies, new work force demographics, and changing conceptions of the role that government should be expected to play.
