Intensive and Extensive Margins of Labor Supply in HANK: Aggregate and Disaggregate Implications

This paper studies how adjustment along intensive and extensive margins of labor supply affects aggregate and disaggregate effects of monetary policy. To this end, I develop a heterogeneous‐agent New Keynesian (HANK) economy where a nonlinear mapping from hours worked into labor services generates operative adjustment along intensive and extensive margins of labor supply. I find that monetary policy has significantly different effects on earnings inequality, depending on the extent to which margin is dominant, even if it generates similar aggregate responses.
