The Structure of Opportunity: How Promotion Ladders Vary within and among Organizations.

This paper analyzes data describing jobs in 100 establishments in order to test hypotheses about the characteristics of jobs and organizations associated with the structure of internal promotion ladders. The diversity of labor market arrangements found within the organizations indicates only weak support for hypotheses linking internal labor markets to organizational or sectoral imperatives. At the job level, however, there is support for hypotheses linking job ladders to firm-specific skills, organizational structure, gender distinctions, technology, occupational differentiation, the institutional environment, and the interests of unions. The paper concludes with an examination of how promotion ladders are formed from clusters of jobs associated with each other by occupation, skill, or gender composition. [ABSTRACT FROM AUTHOR]
