About Me

I am a quantitative sociologist and social demographer at NORC at the University of Chicago. This is my personal website. Find my NORC profile here. I completed my PhD in Sociology at the University of North Carolina in Chapel Hill in 2020 and then was a NICHD postdoctoral fellow at the University of Texas at Austin’s Population Research Center.

I study the intersections of work, poverty, and structural inequality. My research is guided by the question of how social structures and institutions shape the outcomes of workers and households. Studying mobility using longitudinal data is at the center of my approach. When workers change jobs and wages, when households fall into and move out of poverty, the structures that shape these outcomes are more visible.

I take inspiration from the qualitative tradition in sociology in the sociology of work and organizations that investigates how social processes and political economy structure people’s lives. Some of my favorite books include Hochschild’s (1997) The Time Bind, Waldinger and Lichter’s (2003) How the Other Half Works, Reskin and Roos’ (1990) Job Queues, Gender Queues, Soss, Fording, and Schram’s (2011) Disciplining the Poor, and Prasad’s (2012) The Land of Too Much.

Mouw, Ted, Arne L. Kalleberg, and Michael A. Schultz. 2024. “’Stepping Stone’ vs ‘Dead-End’ Jobs: Occupational Structure, Work Experience, and Mobility Out of Low-Wage Jobs,” American Sociological Review. (open access)

Abstract

Does working in a low-wage job lead to increased opportunities for upward mobility, or is it a dead-end that traps workers? In this article, we examine whether low-wage jobs are “stepping stones” that enable workers to move to higher-paid jobs that are linked by institutional mobility ladders and skill transferability. To identify occupational linkages, we create two measures of occupational similarity using data on occupational mobility from matched samples of the Current Population Survey (CPS) and data on multiple dimensions of job skills from the O*NET. We test whether work experience in low-wage occupations increases mobility between linked occupations that results in upward wage mobility. Our analysis uses longitudinal data on low-wage workers from the 1979 National Longitudinal Study of Youth (NLSY) and the 1996 to 2008 panels of the Survey of Income and Program Participation (SIPP). We test the stepping-stone perspective using multinomial conditional logit (MCL) models, which allow us to analyze the joint effects of work experience and occupational linkages on achieving upward wage mobility. We find evidence for stepping-stone mobility in certain areas of the low-wage occupational structure. In these occupations, low-wage workers can acquire skills through work experience that facilitate upward mobility through occupational changes to skill and institutionally linked occupations.

Abstract

How are changes in the low-wage labor market affecting the mobility of workers out of low-wage work? I investigate changes in the wage mobility of workers starting employment spells in low wages using the Panel Study of Income Dynamics from 1968 to 2014 and discrete-time event history analysis. About half of all low-wage workers move to better wages within four years. Effects on mobility rates are significant by age, gender, race, education, occupation, and job characteristics. Mobility rates out of low-wage work have declined since the late 1990s. Little progress has been made in closing the gaps in mobility for women and nonwhites over time. I find evidence for the decline of firm internal labor markets and lower mobility for part-time workers over time.


Schultz, Michael A. “Bring the Households Back In: The Effect of Poverty on the Mobility of Low-Wage Workers to Better Wages,” Working Paper.

Abstract

Although eighty percent of low-wage workers are not in poverty, low-wage work and poverty are often conflated. I distinguish the two and investigate how household conditions affect workers’ mobility out of low-wage work. I argue households are central labor market organizations, parallel to firms, occupations, and unions in explaining labor market inequality. I define households as contested and resourced organizations. I operationalize the contested part of households by investigating how falling into poverty affects low-wage worker’s mobility. I argue that falling into poverty introduces new search frictions as settled patterns of household tasks are re-negotiated. These new search frictions limit mobility consistent with the theory of dynamic monopsony. I operationalize the resourced part of households using 3-year post-tax and transfer income and liquid savings. I analyze data from the Panel Study of Income Dynamics using discrete-time event history analysis. My results are consistent with household search frictions explain the lower mobility of households falling to poverty. First, workers with larger income drops when falling into poverty move to better wages at lower rates. Second, sixty percent of the effect of a household being in poverty in the previous year on a low-wage worker’s mobility is explained by a lack of household resources. Households with longer durations in poverty are characterized by a diminishment of household resources.

Abstract

This paper addresses several key research issues raised by Spilerman’s (1977) landmark article on careers and intragenerational mobility. We first identify three types of careers: employer-based, occupation-based, and those established in occupational internal labor markets (OILMs). We focus on OILMs, which describe a structure that enables upward job and wage mobility through movement across occupations. We use CPS and O*NET data to create measures of occupational similarity and use them—along with indicators of occupational and organizational mobility/immobility—to identify the three career types in longitudinal data from the 1979 National Longitudinal Study of Youth (NLSY). We next derive measures of work experience based on career types and link them to wages. We find that employer, occupation, and OILM experience are all positively related to wages, and that wage returns to OILM experience are greater in occupations with high wage inequality.


Schultz,Michael A., Ted Mouw, and Arne L. Kalleberg. “The Structure of Opportunity and Wage Mobility.” Draft in Preparation.

Abstract

Sociologists use the concept of “the opportunity structure” to describe how opportunities for mobility differ for workers in different places, in different organizations and jobs, and in different social positions, including race, class, and gender positions. Yet, researchers studying workers’ occupational and wage mobility over their careers have found it difficult to operationalize a structural perspective. As a result, the dominant empirical perspectives for workers’ upward mobility are individual supply-side explanations like the human capital and status attainment models. We use occupations as the unit of analysis to define the labor market structure and then use a novel method, multinomial conditional logit (MCL) models, to study three components of the opportunity structure for workers’ wage mobility. The first element is demand for jobs. We modify a Bartik industry demand shock measure by translating the shock to occupations in geographic areas. Second, firm and occupational internal labor markets provide job ladders for upward mobility. We use firm tenure and measures of institutional and skill linkages between occupations to operationalize internal labor markets. Third, opportunities for mobility are structured by the interaction between worker status characteristics, like gender and race, and the status-typing of jobs. We include measures of the gender and racial composition of occupations to study this element. Our data comes from the 2014 panel of the Survey of Income and Program Participation. We account for individual-level characteristics explaining occupation and wage mobility. We find strong evidence of the effect of all three elements on the opportunity structure on workers’ wage mobility./p>


Schultz, Michael A. “Vocational Training and Low-Wage Workers’ Mobility: Access to Job Ladders and the Match Between Training and Jobs in the U.S. and Germany” Draft in Preparation.

Abstract

Low-wage work is a persistent feature of the U.S. labor market with about a quarter of workers in low-wage jobs. About half of all low-wage workers move to better wages in four years. Vocational training programs are a widely discussed policy intervention for increasing low-wage workers’ economic mobility and consequently supporting low-income families. Germany’s vocational education and training system is highlighted as a model by U.S. policy experts. This article investigates the role of vocational training systems in the U.S. and Germany in facilitating low-wage workers’ mobility to better wages. We use harmonized longitudinal data from the U.S. Panel Study of Income Dynamics (PSID) and the German Socio-Economic Panel (GSOEP), growth curve models, and event history analysis. We use novel measures of the match between a workers’ training and their job and operationalize cross-occupation job ladders using a measure of the skill similarity between detailed occupations. A key feature of the success of the German system is the role of firm apprenticeships that links training to jobs resulting in a high match between training and a workers’ job. We investigate how often low-wage workers are achieving these matches, the wage returns to matches, and how these matches changed over time in both countries by gender and for race/ethnic groups. Next, we investigate how vocational education aligns with job ladders that facilitate the accumulation of skills and mobility over time and whether some workers are more or less likely to access these job ladders. The findings of this paper contribute to our understanding of the efficacy of vocational education programs for facilitating low-wage workers’ upward mobility.


Schultz, Michael A. and Ted Mouw. “In Search of Dynamism: Gender Inequality in Changing Occupational Labor Markets,” Working Paper.

Abstract

Progress in reducing the gender pay gap has slowed or even stalled. Three prominent explanations for the gender pay gap are interrelated: occupational sex segregation, the motherhood wage penalty, and the rise of overwork. A challenge for the literature is the lack of a methodological approach that allows researchers to test the relative importance of all three hypotheses in the same analysis. This paper begins to address this methodological challenge by modeling the wage growth and wage returns to occupational changes for men, childless women, and mothers. This second analysis uses a conditional logit. We test for the effects of occupational segregation, compensating differentials, and overwork on explaining differential upward and downward occupational wage moves for childless women and mothers relative to men. Results indicate that most of what we term the job-anchored gender pay gap, or the gender pay in wage growth, is due to the lower wage returns to occupations moves for mothers relative to childless women and men. Mothers are less likely to make occupational moves resulting in large upward wage gains in terms of occupational mean wages due to occupational segregation. Childless women and mothers are both more likely than men to make occupational moves resulting in large downward losses in terms of mean occupational wages. These moves do not look to be explained by compensating differentials and may be due to exit from toxic environments.


Schultz, Michael A. “Constraint or Commitment? Insider Partners and the Gender Gap in Mobility Out of Low-Wage Work,” Working Paper.

Abstract

Sociologists have developed a wide-range of explanations to explain the persistence of gender inequality in the labor market at the micro, meso, and macro levels. Methodological choices and a focus on rejecting the competing explanations derived from human capital theory have limited testing of competing sociological explanations in the same analysis. I organize these sociological explanations into five hypotheses and test two, the work-life boundary maintenance hypothesis and the institutional hypothesis. I use a dynamic model predicting the mobility of low-wage workers to better wages to incorporate and test explanations at the individual, household, and labor market levels of analysis. I find strong support for the work-life boundary maintenance hypothesis that predicts that women labor market choices, here mobility to better wages, are constrained by gendered household, childcare responsibilities, and poverty. My results show that women in low-wage work with more resources, due to being partnered to a labor market insider, are more likely to move out of low-wage work. I find no support for competing commitment hypothesis of human capital theory that predicts that these same women with more resources are more likely to withdraw from the labor market and be less likely to achieve better wages. The institutional hypothesis, that women’s lower mobility is due to lower access than men to labor market institutions promoting wage growth, like union, occupational labor market, and firm labor markets, is not supported.

Schultz, Michael A., Ted Mouw, and Arne Kalleberg. “Interrupted Careers: A New Approach to Measuring Childbirth-Related Career Discontinuities,” Working Paper.

Abstract

A primary obstacle to the study of work and family trajectories across the life course is incorporating detailed longitudinal work histories on employer changes, occupation changes, and job characteristics into the analysis. We develop a measure of career continuity across employer and occupational changes to overcome this obstacle. The central element in our measure of career continuity is the operationalization of occupational internal labor markets (OILMs), or clusters of jobs linked together across detailed occupations that are associated with the development of skills. We measure OILMs using data on occupational mobility from matched samples of the Current Population Survey (CPS) and data on multiple dimensions of job skills from the O*NET. Our results show women experience more OILM career discontinuities then men, particularly after childbirth. We find that OILM career discontinuities, and not employer changes, are the primary explanation for the motherhood wage penalty.


Schultz, Michael A. and Carmen Gutierrez. “The Long Shadow of Mass Incarceration: Race, Incarceration, and Social Security Earnings.” Working Paper.

Abstract

Mass incarceration is a major social program of the past 50 years in the U.S. with broad impacts for race and class inequalities for incarcerated individuals, their children, families, and communities. The cohorts of men coming of age at the beginning of mass incarceration are now approaching retirement age. We investigate the long-term shadow of incarceration in early adulthood across the life course and into later life. Drawing on longitudinal data from the Panel Study of Income Dynamics (PSID), we examine the extent to which incarceration impacts Social Security earnings and racial inequality among individuals of retirement age. We then investigate prominent explanations for this inequality including labor market experience and criminal legal system contact across life course. Our final analysis seeks to estimate the cost of mass incarceration in terms of lost Social Security earnings. We find that mass incarceration has a long afterlife. The cohorts who experienced the height of mass incarceration will reach retirement age in the next two decades with large consequences for inequality in later life.


Auguste, Daniel and Michael A. Schultz “Necessity and Opportunity Entrepreneurship: Inequality in Access to Economic Mobility through Self-Employment” Working Paper.

Abstract

It is widely believed that entrepreneurship constitutes an ideal path for achieving both economic mobility. Yet, due to lack of access to the necessary resources for business development and success, a large portion of the American population is unable to use entrepreneurship as a pathway to economic mobility. We use a longitudinal approach to differentiate necessity and opportunity entrepreneurship. Workers in necessity entrepreneurship have low incomes and typically lack related work experience in the job of their business. Workers in opportunity entrepreneurship typically enter entrepreneurship with a familiarity of the business environment from past work experience and with financial capital. We use longitudinal survey data from the Panel Study of Income Dynamic’s on workers’ careers including entry, exit, and income from self-employment to operationalize necessity and opportunity entrepreneurship and investigate the impact on upward mobility through entrepreneurship. We find that there is a much greater level of necessity entrepreneurship when measured longitudinally using low annual labor income prior to entry than measures solely using unemployment prior to entry. Women and Black entrants to self-employment are much more likely to be in necessity self-employment. We find a high rate of exit from self-employment and this includes workers with opportunity characteristics like more occupational experience and higher labor income prior to entry. The level of financial resources is a primary predictor of upward mobility through self-employment. Necessity entrepreneurship is characterized by longer durations in self-employment at low levels of income.


Schultz, Michael A. “Place and Persistent Poverty: Long Duration Poverty in Urban, Suburban, and Rural Communities.” Working Paper.

Abstract

Persistent poverty is typically defined as a place with a continuously high poverty rate. An alternative approach is to measure persistent poverty at the household level. Households experiencing more than five years in poverty are considered in persistent poverty. Analyzing persistent poverty at the household-level allows for the investigation of variation across places, in particular the difference between places with similar poverty rates, but different amounts of households in short vs long poverty spells. I use the Panel Study of Income Dynamics and analyze variation in persistent poverty by community type and region. I find that the highest percentage of households in persistent poverty are in rural communities in the South and North Central regions. In these two regions, poverty rates have remained high since the 1990s. Persistent poverty is comparatively low across community types in the Northeast and West regions but increased in recent decades. Rates of persistent poverty are higher among Black households than white households and this is particularly the case in the rural South.

Teaching

Approach: At UNC-Chapel Hill I taught courses over four years and developed four courses. I prioritize teaching inequality in every course because multiple forms of inequality are present in all the societal institutions I teach about. I use empirical cases, like the transition from school-to-work and the contest within households over housework, as an entry points for helping students learn critical theory and understand the institutions shaping their lives.

Course Syllabi: (click course title for recent syllabus)

Labor Markets:
I teach students to view the labor market as dynamic and contested, and I emphasize the concepts of social closure, occupational closure, and inhabited institutions. The course is framed around the competing stories of stability and change in the labor market since the 1970s. I focus on the stability and change of levels of inequality in the market and the stability and change of employment relationships between workers and employers. Students analyze a local labor market to learn about labor market structure; they examine cross-national case studies to learn about labor market institutions; and they analyze career trajectories from longitudinal data to learn about the life course.

Social Stratification: Social closure is the pivotal concept of this course. Social closure is the idea that social groups seek to gather and use resources for their own benefit (e.g. parents want their own children to succeed over other people’s children). The three primary hierarchies of inequality (gender, race, class) intersect and interact creating multiple forms of social closure. I demonstrate this intersectionality in the course by using cases from each hierarchy and juxtaposing them. Students learn to see how inequality is multi-dimensional and results from present and historical factors. I use cases and evidence from a wide range of sociology subfields, from intergenerational mobility to the experiences of transmen to cultural class and racial housing segregation.

Organizations: I teach students to view organizations as the spaces where ideas, norms, and meaning are contested and negotiated, with significant variation in outcomes. I use case studies like the emergence of radio stations, the organizational effort to reduce working hours for surgeon interns, and the value of cross-training for improving gender inequality in the workplace. The goal of the course is for students to learn how organizations exist in specific surrounding environments and contain contested environments within the organization. Students consider how inequality is a result of the interaction of the internal and external social forces.

Intro to Sociology: My goal for this course is to teach students how sociologists make arguments from evidence. Students read excerpts from five sociological books (from DuBois’ The Philadelphia Negro to Desmond’s Evicted), and I guide students through the different sociological arguments and evidence they encounter in the reading. I select books from a range of subdisciplines, including classics and more recent work. The books cover a range of methods to maximize students’ exposure to sociology. Students practice using their sociological imagination by seeing how structural factors affect the lives of individuals.
