Divergent Paths: Economic Mobility in the New American Labor Market New York, NY: Russell Sage, 2001 Cohort(s): NLSY79, Young Men Publisher: Russell Sage Foundation Keyword(s): Clare Jellick; Earnings; Job Promotion; Job Turnover; Mobility; Mobility, Economic; Mobility, Labor Market Tracks the fortunes of two generations of young white men over the course of their careers to examine the prospects of upward mobility for workers in America's labor market. Two cohorts were drawn from the National Longitudinal Survey of Young Men & the National Longitudinal Survey of Youth respectively. Members of the first sample were initially interviewed in 1966 & tracked until 1981, while the second sample was interviewed yearly between 1979-1994. The older men entered the labor market at a time of prosperity & stability, while the second group began working in the early 1980s, a time marked by recession, deregulation, & the weakening of organized labor. An overview of the historical context is followed by a detailed analysis of the longitudinal data. It was shown that the second group faced a labor market that was more volatile & characterized by lower job security, higher penalties for failing to find steady employer, & growing inequalities between well-connected workers who used short-term projects to obtain better-paying positions, & increasing numbers of workers stuck in a series of low-paying, high-turnover jobs. It is concluded that the labor market of the 1960s & 1970s launched more workers up the earnings ladder than today's market. Policy strategies for improving the upward mobility of workers in the US are discussed. |

Inequality and Mobility: Trends in Wage Growth for Young Adults Working Paper 99-03, Population Research Institute, The Pennsylvania State University, July 1999. Also: http://www.pop.psu.edu/info-core/library/wp_lists/psu.html#1999 Cohort(s): Young Men Publisher: Population Research Institute, The Pennsylvania State University Keyword(s): Educational Returns; Intergenerational Patterns/Transmission; Mobility; Modeling, Mixed Effects; Occupational Investment; Variables, Independent - Covariate; Wage Differentials; Wage Growth; Wages, Youth Permission to reprint the abstract has not been received from the publisher. After two decades of rising wage inequality, it is important to examine the impact of these changes on lifetime wage growth. This paper compares the intragenerational mobility of two NLS cohorts of young white men: the first entered the labor market in the late 1960s, the second in the early 1980s. For each cohort, we analyze wage profiles across 16 years using a mixed-effects model. We find that long-term wage growth has both stagnated and become more unequal in recent years. Changes in the composition of and returns to education, experience, occupation and other covariates explain about half the rise in inequality, leaving a significant residual. Our findings suggest a decline in the economic welfare of workers who entered the labor market in the 1980s. |

The Transition to Work in the Post-Industrial Labor Market Working Paper 98-12, Population Research Institute, The Pennsylvania State University, August 1998 Cohort(s): NLSY79, Young Men Publisher: Population Research Institute, The Pennsylvania State University Keyword(s): Clare Jellick; Education; Employment, Intermittent/Precarious; Re-employment; Transition, School to Work; Unemployment; Wage Differentials; Wage Growth; Working Conditions Permission to reprint the abstract has not been received from the publisher. Also: Presented: San Francisco, CA, American Sociological Association Meetings, August 1998 American workers have witnessed striking changes in their jobs and wages during the last three decades. It is no longer simply a matter of growing income inequality, but increasingly deeper changes that go to the root of what it means to have a job and to build a career. Young workers are pessimistic about their chances for upward mobility and education no longer seems a guarantee of success. Workplaces are being restructured, creating anxiety about being laid-off and downsized. The recovery of the 1990s did not prove the cure-all that other recoveries have in the past, and disadvantaged groups in particular are being left behind. There is a growing sense that Americans are working under new rules. The very character of the American employment relationship appears to be changing - in how the workplace is organized, in how workers are matched with jobs, and in how wages and the terms of employment are set. This paper reports on a subset of findings from a larger study of the changes in job and wage mobility over the past 30 years. In this study, we compare two cohorts of young white men, from the National Longitudinal Surveys. The original cohort entered the labor market in the late 1960s at the tail of the economic boom, and was followed through the 70s decade. The recent cohort entered the labor market in the early 1980s after the onset of economic restructuring, and was followed through the early 90s. We observe both cohorts for a full 16 years, at exactly the same ages - respondents are in their late teens and early 20s at the start of the survey, and are in their mid-30s by the end. We can therefore compare the progress of the two cohorts during the initial stages of their careers, but under different economic conditions. It is during this period that workers make the transition from school to work, and lay the groundwork for an eventual long-term relationship wi th an employer. The key finding reported in this paper is that the transition to the labor market has become longer and more volatile. Young workers who do not go on to college are more likely to be intermittently unemployed and to rely on part-time jobs for a greater number of years. This is especially marked among high school dropouts. Those who do go on to college are more likely to work while enrolled and to significantly draw out the period of enrollment. For both groups, it takes longer to find a full-year job than it has in the past. The recent cohort is also less likely to make a single, clean transition to the labor market. Instead, these young workers are more likely to move back and forth between work, unemployment, enrollment, and non-participation. Workers at all levels of education have experienced this greater volatility, but it has been most pronounced among those with less education. There is noticeably more shifting between industries in the recent cohort, at all ages. Some of this is driven by deindustrialization and the shift to service industries, but not all of it. The greater volatility on these dimensions has taken its toll on the work experience that young workers accumulate. Average work experience is similar across the two cohorts. But there is considerably more variability in the amount of work experience that the recent cohort has accumulated, and this holds true across all education groups. Findings from the larger study indicate that this contributes to greater inequality in wages and wage growth for this cohort, trends that are likely to persist over their life course. |

Wage Inequality and Labor Market Segmentation: Evidence from the National Longitudinal Study Cohorts Presented: Chicago, IL, Population Association of America Meetings, April 1998 Cohort(s): NLSY79, Young Men Publisher: Population Association of America Keyword(s): Clare Jellick; Labor Market Segmentation; Mobility; Mobility, Economic; Wage Equations; Wage Growth Permission to reprint the abstract has not been received from the publisher. The long term implications of the recent dramatic growth in economic inequality are not well understood. A key question is whether growing cross-sectional inequality is being driven by rising labor market segmentation into winners and losers: some workers with jobs that provide high wages and economic mobility, but others caught in a cycle of dead-end jobs with little opportunity for lifetime wage growth. We analyze the early work histories of two cohorts of young white men from the NLS for evidence of such changes. Both cohorts are 14-22 at entry and are followed for 16 years. The original cohort entered in 1966, the recent in 1979. We find that job instability has risen in the recent cohort, and that their longitudinal age-earnings profiles are becoming more unequal. The evidence suggests that labor market segmentation is rising, and that members of the recent cohort face a lifetime of greater inequality. |

Wage Inequality and Labor Market Segmentation: Evidence from the National Longitudinal Study Cohorts Working Paper 98-07, Population Research Institute, The Pennsylvania State University, April 1998. Also: ftp://ftp.pop.psu.edu/papers/psu-pri/wp9807.pdf Cohort(s): NLSY79, Young Men Publisher: Population Research Institute, The Pennsylvania State University Keyword(s): Education; Job Training; Job Turnover; Labor Market Segmentation; Marriage; Unions; Wage Growth Permission to reprint the abstract has not been received from the publisher. In this paper, we take up the question of whether there has been a secular rise in job instability among young workers over the past three decades. We compare two NLS cohorts of young white men - the first cohort entering the labor market in the late 60s and throughout the 70s, and the second during the 80s and early 90s. Using longitudinal data on work history and schooling, we find a significant increase in the rate of job changing across the two cohorts. Some of the increase is explained by the trend toward lower marriage rates and longer transitions into the labor market. The economy's shift toward the service sector has also played an important role, although declines in stability have occurred in traditionally unionized industries as well. Together, these factors explain about one-half of the cohort difference. The overall rise in instability has resulted in shorter median tenures. While greater job instability and shorter tenures are not necessarily a bad thing - job changing can be beneficial to wage growth early in the career - we find that young workers in recent years have failed to capture the all-important wage gains that were associated with job changing in the past. This deterioration in wage gains has been felt largely by less educated workers, but inequality in these gains has also increased, for all education groups. In combination, our findings suggest declines in the long-term economic welfare of recent entrants into the labor market. |

Summary. We develop an affinity model for longitudinal categorical data in which the number of categories is large and we apply the technique to 20 years of labour market data for a contemporary cohort of young adult workers in the USA. The method provides a representation of the underlying complexity of the labour market that can then be augmented to include covariate effects. These can be understood as effects net of transition patterns associated with labour market sorting. We include in our model pairwise affinities to relate nominal categories representing types of job. The affinities capture complex relationships between these types of job and how they change over time. We evaluate the role of gender and education to illustrate the different types of questions and answers that are addressed by this methodology. |

Statistical Models for Heterogeneity in the Labor Market Ph.D. Dissertation, New York University, Graduate School of Business Administration, 1998 Cohort(s): Young Men Publisher: UMI - University Microfilms, Bell and Howell Information and Learning Keyword(s): Heterogeneity; Longitudinal Data Sets; Modeling, Mixed Effects We develop a latent curve model for longitudinal data which captures underlying stochastic variation in an interpretable manner. The approach decomposes the variation into data-adaptive components, which we call proto-splines. These components are linear combinations of basis functions chosen to reflect important features of the process under investigation. Our approach can be viewed as a hybrid of principal components analysis and the usual basis function approach to functional data analysis. The resulting components should be more interpretable than principal components and are more flexible than those employed in the basis function approach. In the course of the development we synthesize many diverse approaches to longitudinal data analysis, and propose a framework for determining which technique is appropriate in a given situation. Our proto-spline model class extends the scope of traditional mixed effects models, but still retains their emphasis on the estimation of components of variance, which often have substantive meaning. We demonstrate the consistency, asymptotic efficiency, and normality of the parameter estimates. An application to the analysis of wage inequality based on the National Longitudinal Survey of Young Men is presented in detail, and various diagnostic techniques for longitudinal data are introduced in this context. |

Pathways to Educational Attainment and their Effect on Early Career Development NCRVE Publication MDS-1296. Berkeley, CA: National Center for Research in Vocational Education, University of California - Berkeley, November 1999. Also: http://136.165.122.102/UserFiles/File/mdspubs/mds1296.pdf Cohort(s): NLSY79, Young Men Publisher: National Center for Research in Vocational Education, University of California, Berkeley Keyword(s): Educational Attainment; Educational Returns; High School Completion/Graduates; High School Dropouts; Mobility; Wage Growth; Wages, Youth Permission to reprint the abstract has not been received from the publisher. We begin this report by comparing long-term wage growth-a measure of upward mobility-for two cohorts of young white men. These men entered the labor market during very different economic periods, with the original cohort entering in the late 1960s, at the tail of the post-World War II economic boom, and the recent cohort entering in the early 1980s after the onset of economic restructuring. We find that long-term wage growth between the ages of 16 and 36 has both declined and become significantly more unequal for the recent cohort. The declines have been concentrated among less educated workers (i.e., high school dropouts and high school graduates). Also worrisome are our findings for workers with sub-baccalaureate degrees or only some college experience. While these workers have a clear advantage over high school graduates in terms of wage growth, that advantage has not increased noticeably in recent years. By contrast, young adults with a bachelor's degree or higher have seen increases in their wage growth. The rising demand for education and skill in the new labor market has apparently benefited only those with four-year college degrees. It has not trickled down to improve the wage growth of those with some college experience or associate's degrees. Education is not the whole story, however, as we find rising inequality in wage growth within all education groups. Thus, there has been a dramatic reduction in mobility opportunities for less-educated young men, but even among the well-educated, there are now many more extreme winners and losers. Educational credentials no longer ensure success with the certainty that they once did. These trends raise a difficult challenge to public policies aimed at improving the living standards and upward mobility of American workers...The question is whether these emerging pathways have paid off. Descriptive evidence suggests that they have been beneficial for some workers but not for others. In particular, there has been a det erioration in wage growth when interrupting and then returning to school-especially among those with only some college experience or with associate's degrees. It also appears that the new pathways are generating more polar and unequal wage outcomes in recent years, especially those involving interruptions to schooling. |

Covariance Models for Latent Structure in Longitudinal Data Working Paper No. 14, Center for Statistics and the Social Sciences, University of Washington, December 2000. Also: http://www.csss.washington.edu/Papers/wp14.pdf Cohort(s): NLSY79, Young Men Publisher: Center for Statistics and the Social Sciences, University of Washington Keyword(s): Data Analysis; Heterogeneity; Longitudinal Data Sets; Modeling, Mixed Effects; Modeling, Multilevel; Modeling, Random Effects; Statistical Analysis; Variables, Independent - Covariate; Wage Equations; Wage Gap Permission to reprint the abstract has not been received from the publisher. We present several approaches to modeling latent structure in longitudinal studies when the covariance itself is the primary focus of the analysis. This is a departure from much of the work on longitudinal data analysis, in which attention is focused solely on the cross-sectional mean and the influence of covariates on the mean. Such analyses are particularly important in policy-related studies, in which the heterogeneity of the population is of interest. We describe several traditional approaches to this modeling and introduce a flexible, parsimonious class of covariance models appropriate to such analyses. This class, while rooted in the tradition of mixed effects and random coefficient models, merges several disparate modeling philosophies into what we view as a hybrid approach to longitudinal data modeling. We discuss the implications of this approach and its alternatives especially on model interpretation. We compare several implementations of this class to more commonly employed mixed effects models to describe the strengths and limitations of each. These alternatives are compared in an application to long-term trends in wage inequality for young workers. The findings provide additional guidance for the model formulation process in both statistical and substantive senses.

Persistent Inequality? Answers From Hybrid Models for Longitudinal Data Sociological Methods and Research 34,1 (August 2005): 3-30. Also: http://smr.sagepub.com/content/34/1/3.abstract Cohort(s): NLSY79 Publisher: Sage Publications Keyword(s): Income Distribution; Intergenerational Patterns/Transmission; Wage Dynamics; Wealth Permission to reprint the abstract has not been received from the publisher. Many questions in social research must be evaluated over time. For example, in studies of intragenerational mobility, measuring opportunity for economic advancement requires longitudinal data. The authors develop and use a class of hybrid functional models to demonstrate how different models can lead to extremely different substantive conclusions. They provide guidelines for longitudinal data analyses in which variance partitions are central to the inquiry. In their analysis of the National Longitudinal Survey of Youth, the authors conclude that in a period of rising wage dispersion, the bulk of inequality is persistent over the life course. Their models provide support for the scenario in which wage inequality rises steadily while instability slowly diminishes over time. They obtain mild evidence of increased wage instability for somewhat older workers in the early 1990s, matching a recessionary trend. These findings contribute significantly to understanding wage inequality in United States over the past 25 years. [ABSTRACT FROM AUTHOR] |
