Discussion of "Singles, Couples, Time-Averaging, and Taxation"

This discussion comments on "Singles, Couples, Time-Averaging, and Taxation" by Hans Holter, Lars Ljungqvist, Thomas Sargent, and Serhiy Stepanchuk. This work represents an exciting new agenda, combining recent findings in the dynamic micro labor supply and retirement literature with key features of the macro environment by including general equilibrium feedback and a government budget constraint. We point to some areas where the specification could be improved but these do not detract from the key insights in this paper and the significant steps it makes toward building a coherent micro and macro framework for research on labor supply and taxation.
