In the United States, market hours worked are approximately flat across the wealth distribution. Accounting for this phenomenon is a standing challenge for standard heterogeneous-agent macro models. In these models, wealthier households consume more and work fewer hours. We propose a theory that generates the cross-sectional wealth-hours relation as in the data. We quantify this theory in a heterogeneous-agent incomplete-markets model with three key features: a quality choice in consumption, non-homothetic preferences, and a multi-sector production structure. We show that the model produces consumption expenditure patterns consistent with the data and realistic “quality Engel curves.”
