“…This hypothesis, labelled the FJH revision by Erikson et al, leads to the prediction that mobility chances are invariant once variations in origin and destination distributions have been controlled. Although the FJH revision has been supported by pairwise or three-way comparisons (Erikson et al, 1982;McRoberts and Selbee, 1981;Hope, 1982;Portocarero, 1983;Hauser, 1983), research with a larger sample of countries has tended to emphasize cross-national variability (Tyree et al, 1979;Hazelrigg and Garnier, 1976;McClendon, 1980a).2 There is also some disagreement about the degree to which "structural influences," reflected in the margins of the mobility table, can account for national differences in observed mobility rates. The FJH revision implies that variation in observed mobility must be attributed to marginal differences, yet McClendon (1980b) has recently reported a contrary finding among industrialized nations.…”
