Assess learners' ability to apply behavioral economics principles—nudges, defaults, incentives, social norms, commitment devices, framing, and feedback—to design, implement, and evaluate workplace wellness interventions. Tasks include creating intervention prototypes for common goals (physical activity, healthy eating, smoking cessation, stress reduction), selecting appropriate techniques, predicting behavioral responses, addressing equity and ethical concerns, defining measurable outcomes and cost-effectiveness, and identifying implementation barriers and scaling strategies. Emphasis is on practical application, trade-offs, and evaluation planning.
