Wages and wage dynamics directly affect individuals' and families' daily lives. In this article, we show how major theoretical branches of research on wages and inequality-that is, cumulative advantage (CA), human capital theory, and the lifespan perspective-can be integrated into a coherent statistical framework and analyzed with multilevel dynamic structural equation modeling (DSEM). This opens up a new way to empirically investigate the mechanisms that drive growing inequality over time. We demonstrate the new approach by making use of longitudinal, representative U.S. data (NLSY-79). Analyses revealed fundamental between-person differences in both initial wages and autoregressive wage growth rates across the lifespan. Only 0.5% of the sample experienced a "strict" CA and unbounded wage growth, whereas most individuals revealed logarithmic wage growth over time. Adolescent intelligence and adult educational levels explained substantial heterogeneity in both parameters. We discuss how DSEM may help researchers study CA processes and related developmental dynamics, and we highlight the extensions and limitations of the DSEM framework.
Importance: People with disabilities experience pervasive health disparities driven by adverse social determinants of health, such as unemployment. Section 14(c) of the 1938 Fair Labor Standards Act has been a controversial policy that allows people with disabilities to be paid below the prevailing minimum wage, but its impact on employment remains unknown despite ongoing national debates about its repeal.
Objective: To estimate whether state-level repeal of Section 14(c) was associated with employment-related outcomes for people with cognitive disability.
The labour market dualisation theory claims that labour unions bargain against the interests of temporary workers and that they foster inequalities between temporary and permanent employees. Conversely, the industrial relations literature argues that unions commonly follow solidaristic strategies towards outsiders. This study contributes to the literature by analysing unions' associations with temporary workers' hourly wages and the wage gap between permanent and temporary workers in Spain: one of the most prominent examples of labour market dualisation.
Introduction: Between 2020 and 2022, there was a rise in employment and entrepreneurial activity, despite some unemployment growth. In the Compulsory Social Health Insurance (CSHI), insured individuals, especially privileged and wage workers, increased. However, certain contributors, like those exempt from contributions and single social taxpayers, decreased, possibly due to legislative changes or the economic climate.
Unlabelled: To compare the difference between primary homoeopathic and conventional paediatric care in treating acute illnesses in children in their first 24 months of life. One hundred eight Indian singleton newborns delivered at 37 to 42 weeks gestation were randomised at birth (1:1) to receive either homoeopathic or conventional primary care for any acute illness over the study period. In the homoeopathic group, conventional medical treatment was added when medically indicated.
In 2024, the average annual premium for employer-sponsored family health coverage was $25,572, an increase of $1,604 (7 percent) from 2023. Over the course of the past five years, the average family premium has increased 24 percent, which is similar to growth seen in inflation (23 percent) and wages (28 percent). On average, covered workers contributed 16 percent ($1,368) of the cost of single coverage and 25 percent ($6,296) of the cost of family coverage.
