Intergeneration occupational mobility and income

The relationship between intergeneration occupational mobility and income is examined in three independent studies: (1) a sample of older men in Detroit, (2) a sample of working age men residing in one of six medium to large sized cities, and (3) a nationally representative sample of working age men. In all three studies, mobile men have lower incomes than do stable men. However, neither the direction nor the degree of mobility appears to affect income in any of the studies examined. The basic relationship between mobility per se and income does not disappear when controls are introduced for work experience, schooling, occupational origins, and occupational destinations. The observed impact of intergeneration occupational mobility on income is consistent with the view that fathers can use their personal and organizational connections to help their sons secure well-paying positions so long as the sons remain in occupations that are similar in status to those of their fathers.     

Trends in occupational mobility in Hungary under socialism

Sociologists have long been interested in the impact of social, economic, and political changes on societal openness. Among other questions, they have asked whether the transition from a preindustrial agrarian society to an industrial socialist state creates more opportunity and equality. Using recent developments in loglinear modeling, this paper tests competing theories about temporal change in social mobility in Hungary in the past half-century. While occupational persistence declined significantly between older cohorts of men and women, the decline slowed or halted in recent cohorts. This suggests that a process of restratification occurred after the socialist revolution. Gender differences in mobility are also prominent. On the one hand, women are less likely than men to enter their fathers' occupational class. On the other hand, women's occupational destinations are more strongly determined by occupational origins. Furthermore, there are significant gender differences in occupational opportunities.     

A canonical approach to assessing occupational mobility matrices

This paper develops a summary measure of occupational persistence which does not require translating the occupational categories into status scale scores. The measure is based on the mean of the squared canonical correlations extracted from a general mobility matrix. The procedure is employed to assess the impact of rapid regional economic diversification on the movement of labor within the occupational structure.     

Problems of concept and measurement in the comparative study of occupational mobility

This paper argues that, despite a great deal of research on the topic, we have almost no firm knowledge about societal differences in the rates, patterns, and processes of occupational mobility. Insufficient attention has been paid by previous researchers to the problem of standardizing the measurement of occupational status. As a result, the paper demonstrates, existing cross-national comparisons of mobility are virtually invalid. A Standard International Occupational Prestige Scale developed by the author is proposed as a basis for valid cross-national comparison. Properties of the scale are discussed and results achieved with the scale are compared to those based on other occupational scaling procedures.     

Psychological and cultural factors in the process of occupational achievement

An eight-equation model embodies the hypothesis that cultural differences among ethnic-religious groups give rise to differences in psychological dispositions, which, though not directly observable, influence occupational achievement, directly or via educational attainment, while being subject to feedback from one or the other of these endogenous variables. Dispositions are reflected in three fallible indicators, constructed from items in a survey interview of native white men in the Detroit area; the survey also secured socioeconomic measures and an estimate of intelligence. The model is block recursive and over-identified. Parameter estimates are secured by a sequence of ordinary least squares and two-stage least squares procedures, after solving out the structural equations to eliminate the unobservable variables. Numerical results do not strongly support the “Protestant Ethic” theory of achievement, but do suggest that the influence of education on occupation is mediated by motivational as well as cognitive and institutional factors.     

Gender differences in the impact of job mobility on earnings: The role of occupational segregation

In recent years, researchers have begun to explore the extent to which the impact of switching firms (inter-firm mobility) on wages varies between men and women. Using data from the NLSY79 from 1979 to 2012, this paper extends existing research by exploring how occupational segregation and individual level factors contribute to gender differences in the impact of voluntary inter-firm mobility on wages. The paper also examines how patterns vary depending on education level. Findings suggest that men without a college education receive greater wage gains from voluntary inter-firm mobility than similarly educated women although there is no overall gender difference for individuals with a bachelor's degree. The wage returns to voluntary inter-firm mobility for both men and women increase as a function of the male representation in the occupation. For individuals without a college education, the male premium to voluntary inter-firm mobility is largest in highly male dominated occupations. However, women with a bachelor's degree employed in highly male dominated occupations use voluntary inter-firm mobility to narrow the gender wage gap.     

Assumptions of social mobility research in the U.S.: The case of occupational status

This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia.     

Career mobility and job flocking

Flocking is oftentimes used to metaphorically describe social behavior. Do people actually flock in a way that avian species do? This paper develops a purely ecological mechanism for explaining similarity in human behavior by distinguishing between social networks of person-to-person ties and ecological networks of ties of observability. I test the “information center hypothesis” [Ibis 115 (1973) 517] from bioecology on the career mobility of professional managers who all graduated from the same university. In this case, spatial proximity in birds is replaced with sociodemographic homophily on an acquired status characteristic among persons. The results indicate that homophilous individuals exchange information about a favorable destination state by ecological ties of observability, that is, they follow the career mobility of fellow alumni and “flock” along with them.     

Ability and mobility: The relative influence of skills and social origin on social mobility

The recent PIACC data offer us the first ever opportunity to identify the relative salience of abilities versus social origin in comparative social mobility research. Sampling 21 countries, we identify the degree of meritocratic selection by estimating the relative influence of social origin versus individual cognitive and social skills. We pay particular attention to the possibility of skills combinations as regards both upward and downward mobility. Social skills may compensate for weak cognitive abilities, or vice-versa; and what are the added effects of commanding strong skills on both counts? This is, as far as we know, the first time that comparative mobility research has examined such skills-complementarities. As in previous research we, too, uncover a significantly more egalitarian mobility pattern in the Nordic countries. This however obtains also for Canada and the Netherlands. A unique feature of Scandinavia is its asymmetric profile: significant upward mobility for those of low social origin, but surprisingly little downward mobility among those of privileged origins. Contrary to expectations, this cannot be ascribed to skills compensation. We find, however, that social skills play an important role for upward mobility among low-SES sons.     

Educational indicators and occupational achievement

Many sociological and economic studies assume that the variable, Highest Grade Completed in School, is by itself an adequate measure of people's education for the purpose of explaining their occupational achievement. Use of Highest Grade Completed as the sole measure of education has at least two major shortcomings. It assumes people have (1) learned the same amount of (2) the same thing in an academic year. Supplementary education indicators are identified and tested to see if they have a substantial impact on occupational prestige or earnings. Background social statuses and Highest Grade Completed are controlled for in this test. Only measures of subject matter studied in high school or college have a statistically significant relationship with occupational achievement net of Highest Grade Completed and social background variables. Highest Grade Completed is quite adequate in measuring the impact of education on occupational achievement without help from the measures of subject matter studied.

Models of social mobility

Properties of measures and models of social mobility are analyzed in relation to the conceptualization of mobility. Two main objectives of mobility research are identified. One is the study of determinants of occupational achievement, the other is the study of mobility as a characteristic of social systems. It is shown that the realization of both objectives is hindered by a failure of commonly used models and measures of mobility to separate out the various individual and structural factors responsible for mobility.

Intergenerational and career mobility in Britain: An integrated analysis

Mobility analysis has traditionally concentrated on the task of charting flows in the two-way contingency table which relates occupational origin to occupational destination. It has not yet undertaken a unified analysis of intergenerational and intragenerational aspects of mobility. And only rarely does it incorporate terms which represent ordered concepts such as inequality or vertical movement. In contrast, path analysis has typically imposed strong orderings on the data, and it has been employed to tease out the relations among several occupational variables. Its main defect is that it entirely abstracts from shifts in mean occupational position, and also from change in the shape of the occupational distribution. Yet both of these are important sources of mobility. The present paper shows how two innovations in mobility analysis may be generalized to constitute a technique which unites the strengths of path analysis with those of log-linear analysis. The two innovations are (a) the conceptual disaggregation of perfect and exchange mobility, and (b) the imposition of an ordered component within each (K. Hope, 1981, Sociology 15, 19–55). The outcome of this generalization is a simple yet powerful account of mobility in Britain.     

社会流动的反思

改革开放以来,中国社会结构的重大变化之一就是形成了大规模、多层次的社会流动。这给社会稳定的维持带来了诸多难题,但同时也具有消除平均主义、在社会成员中间造成压力和动力、促进资源合理配置、形成滴漏效应、缓解因社会差异引致的社会矛盾等多重效应,使社会稳定本身经受了考验。从未来看,社会流动表现出频繁化、规范化、地区化、全球化等重要趋势,这是值得注意的影响社会稳定的新因素。     

Measures of occupational status in a special population

Previous research has shown that indirect measures of occupational status such as the Duncan Socioeconomic Index (SEI) are more valid than direct measures of occupational prestige, such as those developed by the National Opinion Research Center and by Treiman, for analyses of social mobility. The Professional, Technical, and Kindred (PTK) occupations available for the SEI are a biased sample of all PTK occupations. Do findings on the validity of the SEI pertaining to the general population hold for special populations, such as college graduates? Confirmatory factor analysis comparing the validities of four measures of occupational SES—the SEI, a 1960 counterpart of the SEI developed by Siegel and based on all Census occupations, the NORC prestige scale, and the Treiman international prestige scale—showed that the indirect measure developed by Siegel was clearly more valid than the other three measures. Since these findings indicate that the predictors in a regression equation are more valid than the criterion, there is some question as to what the criterion should really be.
