Selected research

My work combines empirical labor economics with theoretical research on incentives and organizations.

01Working paper

Working Days and Working Hours in an Expanding Economy

with Wolter Hassink and Baocai Guo

Using China Household Finance Survey panel data from 2011 to 2019, this paper studies working days per week and working hours per day as distinct labor-input margins. The findings point to moderate complementarity and suggest that extended schedules are more consistent with employer-side scheduling needs.

02Working paper

Nominal Wage Dynamics in China

with Wolter Hassink and Baocai Guo

This paper documents weak downward nominal wage rigidity and frequent nominal wage cuts among job stayers in China. Wage cuts are much less persistent for individuals than in the aggregate, while exposure varies across worker and job characteristics, most clearly by education.

Optimal Incentives for Heterogeneous Spillover Effects

with Kris De Jaegher

A principal-agent model characterizes incentive design when agents' efforts affect multiple performance signals in different directions. Collective evaluation is optimal with positive spillovers, relative evaluation with negative spillovers, and the optimal effort profile depends on spillover intensity, signal noise, and revenue interactions.

Research at the intersection of workers and firms

I am a PhD candidate at Utrecht University School of Economics. My research asks how labor-market outcomes emerge from the choices of workers, firms, and institutions.

My empirical work uses longitudinal household data to study how working schedules and nominal wages adjust in China. My theoretical work examines how organizations should design contracts when employees' efforts affect one another's performance signals.
