A Model for Occupational Careers.

This paper suggests a model for occupational careers based on the outcome of job shifts. This outcome may be described by a difference equation, where the gain is a function of the prestige and income of the job left and a person's level of resources. The career model is obtained as a solution to this difference equation. The resulting age profile is governed by a parameter: b-sub-one. This parameter is interpreted to measure the degree to which the occupational structure provides opportunities for gains in occupational achievement, given unchanged resources of the individual. On the individual job shift level, this is argued as being reflected in the degree of control individuals have on their job shifts. The increment in return on resources due to job shifts is also argued to be determined by structural characteristics. The interpretation of the parameters is tested with satisfactory results.
