STRUCTURAL TRANSFORMATION AND SOCIAL MOBILITY: HUNGARY 1938-1973.

This paper describes several ways in which the transformation of Hungarian social structure between 1938 and 1973 constrained changes in rates of Intergenerational social mobility. Three concepts of ways in which shifts in the distributions of social origins and destinations can result in changes. in the total rate of mobility-"discrepancy effects," "concentration effects," and "composition effects" -are discussed and shown to be represented in a multiplicative model commonly applied to mobility tables. By observing the changes in the expected percentage mobile when various constraints are added to this multiplicative model, the relative impact of each aspect of structural change becomes more apparent Most of the change in Hungary, particularly between 1953 and 1973, is attributable to changes in structural constraints. Most of the change in mobility across economic classes was associated with changing origin-destination discrepancy effects, as were large portions of the changes in mobility across socioeconomic status levels and broad social strata. Changing concentration effects were less important, and mostly affected mobility across SES levels. Detailed composition effects were most important in conjunction with monotonic increases in mobility across SES levels. [ABSTRACT FROM AUTHOR]
