Extensions of the Mover-Stayer Model

Spilerman, Seymour

A major drawback to the traditional Markov formulation of mobility processes is that it assumes population homogeneity with respect to transition behavior. This assumption is clearly violated in most instances of social mobility. In an attempt to relax the homogeneity requirement and still retain the essential character of a Markov process, Blumen, Kogan, and McCarthy (1955) developed the "mover-stayer" model in which heterogeneity is attributed to the presence of two types of persons who differ in their rates of move- ment. In the present paper, the mover-stayer model is generalized to permit a continuous distribution of persons by rate of mobility. The model is illustrated with simulated data and then applied to an analysis of interregional migration.
