Organized Labor and Depression in Europe: Making Power Explicit in the Political Economy of Health.

Despite engagement with the construct of power relations, research on the political economy of health has largely overlooked organized labor as a determinant of well-being. Grounded in the theory of power resources, our study aims to fill this gap by investigating the link between country-level union density and mental health while accounting for the compositional effects of individual-level union membership. We use three waves of the European Social Survey (N = 52,737) and a variation on traditional random-effects models to estimate both the contextual and change effects of labor unions on depressive symptoms. We find that country-level union density is associated with fewer depressive symptoms and that this is true irrespective of union membership. We discuss our findings vis-à-vis the literatures on the political economy of health, power resources, and fundamental causes of disease.
