How Do Employer Practices Affect Economic Mobility
How can employers facilitate economic mobility for workers, particularly workers of color or those without a college degree? The authors integrate a fragmented literature to assess how employers' practices affect enhanced economic security and mobility. This article first identifies three pathways linking employers' practices to mobility: improving material job quality, increasing access to better jobs for historically marginalized workers, and p…
A missing behavioural feedback in Covid-19 models is the key to several puzzles
⇒ Human actions have played a key role in shaping the COVID-19 pandemic patterns. While theoretically recognised, existing models of epidemics often do not endogenously capture many of the feedback loops connecting people’s choices and epidemic dynamics, for example, adoption of non-pharmaceutical interventions (NPIs) by individuals and governments shapes disease transmission, which in turn alters perceived risks and future NPI adoption. ⇒ Such ‘…

Dynamics of Implementation and Maintenance of Organizational Health Interventions
In this study, we present case studies to explore the dynamics of implementation and maintenance of health interventions. We analyze how specific interventions are built and eroded, how the building and erosion mechanisms are interconnected, and why we can see significantly different erosion rates across otherwise similar organizations. We use multiple comparative obesity prevention case studies to provide empirical information on the mechanisms …
Dynamic Interplay Among Homeostatic, Hedonic, and Cognitive Feedback Circuits Regulating Body Weight
Obesity is associated with a prolonged imbalance between energy intake and expenditure, both of which are regulated by multiple feedback processes within and across individuals. These processes constitute 3 hierarchical control systems—homeostatic, hedonic, and cognitive—with extensive interaction among them. Understanding complex eating behavior requires consideration of all 3 systems and their interactions. Existing models of these processes ar…
Modeling US Adult Obesity Trends
Objectives. We present a system dynamics model that quantifies the energy imbalance gap responsible for the US adult obesity epidemic among gender and racial subpopulations. Methods. We divided the adult population into gender–race/ethnicity subpopulations and body mass index (BMI) classes. We defined transition rates between classes as a function of metabolic dynamics of individuals within each class. We estimated energy intake in each BMI class…
