Benjamin Jarvis and Xi Song (2017)- Rising Intragenerational Occupational Mobility in the United States, 1969 to 2011

3. Cheng (2014)
Her study establishes a Life Course Trajectory (LCT) framework that scrutinizes the macrolevel intracohort pattern of wage inequality from its microlevel basis
This framework accounts for the
The random variability in wage attainment (random variability property)
The heterogeneity in wage attainment (trajectory heterogeneity property)
The cumulative advantage in age attainment (cumulative attainment property)

4. Cheng (2014): Hypotheses
Intracohort inequality will increase over the life course as a result of the accumulation of random variability over time
Intracohort inequality will increase over the life course as a result of the heterogeneity in the life course wage trajectories
Intracohort inequality will increase over the life course as a result of the mechanism of cumulative advantage

10. Cheng (2014): Conclusi
Makes theoretical, empirical and methodological contributions to sociological literature
Theoretical- the study provides a theoretical framework that explains the process through which the life course wage dynamics on the individual level give rise to the pattern of inequality on aggregate level.
Empirical contribution- confirms the contribution of different mechanisms (57.40%) to intracohort growth in wage inequality in the US.
Methodological- Illustrated a method for decomposing the change in total wage inequality into separate components

11. Jarvis and Song (2017)
Proposed that rising intragenerational occupational mobility might have prevented declines in intergenerational occupational mobility [which are expected due to rising inequality]
Sought to provide a more nuanced picture of how occupational mobility patterns have been changing over the past four decades
How the changes are related to broader changes in the U.S. economy and labor force
Examine their implications for trends in intergenerational mobility

13. Jarvis and Song (2017)
Intragenerational Mobility and Macro-Social Changes
Changing labor force composition
Changing employment relationships
Changing industrial structure

14. Jarvis and Song (2014)- Trends in gross mobility

15. Jarvis and Song (2014)
Trends in mobility between manual and non-manual sectors - on the rise for both men and women. More pronounced for women due to structural mobility

16. Jarvis and Song (2014)
Trends in Net Macro- Class Mobility - increasing counterfactual mobility for men and women between macro-classes within the non-manual sector; relatively flat mobility in the manual sector

17. Jarvis and Song (2014)
Trends in Net Meso- Class Mobility: Increasing for both sexes—stronger for men, weaker for women especially in professional-managerial occupations.

18. Jarvis and Song (2014)
Trends in Net Micro- Class Mobility: for men- weak to mildly positive; for women- uneven in all meso-level classes except in service occupations

19. Jarvis and Song (2014)
Trends in Net Micro- Class Immobility: Men have experienced more declining class immobility across all meso-levels; women show no change for some classes

20. Jarvis and Song (2017): Summary Table

21. Jarvis and Song (2014) Conclusion
Changes in mobility cannot be easily explained away by changes in demographic composition of the labor force
Found strong support in macro level structural forces—technological changes, de-unionization, precarious employment practices
Technological change explains decreases in micro-class persistence affecting mostly clerical, craft, and sales meso-classes
De-unionization is supported by increasing mobility especially for men in the manual sector, and increasing mobility between meso-classes in the manual sector
Widespread increases in intragenerational mobility across levels of aggregation and tiers of the class structure, consistent with the rise of precarious labor
