Welcome! I am a Ph.D. candidate in Economics at the University of Basel.
My interests lie in health economics, labour economics, social insurance design and applied econometrics.
I visited the Center for Labor Economics at the University of California, Berkeley, from January to March 2022.
Before my doctoral studies, I worked as a research fellow in health economics at Unisanté.
I study how individuals respond to the economic incentives created by health insurance, unemployment insurance, and income taxation systems. Current topics include
- The strategic timing of healthcare consumption
- The design of unemployment insurance with heterogeneous responses to coverage generosity
- The labour supply responses of low-income workers to income tax incentives.
In my research, I develop new causal identification designs derived from theoretical models, and implement them using large administrative or survey data.
Timing Moral Hazard under Deductibles in Health Insurance. — draft available upon request
AbstractThis paper develops a new approach to identifying timing moral hazard in health insurance contracts when deductible choice is endogenous. I set up a dynamic model of healthcare consumption where individuals exceed a high deductible after a large health shock. I show that individuals either strategically prepone care from the year after the shock and keep a high deductible, or do not retime and switch to a low deductible the year after. The identification of timing moral hazard exploits the randomness of shock timing within a calendar year. Empirical results show quantitatively significant timing moral hazard responses, which decrease with the time left to the deductible reset. This pattern suggests that there are substantial frictions to preponing, and that dynamic changes in incentives matter in shaping strategic timing responses.
Unemployment Insurance with Response Heterogeneity (with Conny Wunsch). — draft available upon request
AbstractThe generosity of unemployment insurance (UI) coverage varies with the worker's age and time contributed to social security in many publicly-funded UI systems, despite a lack of evidence on their relevance for UI policy differentiation. This paper studies whether the responses to UI and the implied fiscal externality vary in these two characteristics. We use administrative data from Germany and a multi-cutoff regression discontinuity design to estimate a comprehensive set of duration and wage elasticities at many discontinuities in potential benefit duration. We find that the fiscal externality of UI decreases with contribution time, but increases with age. These gradients are mainly driven by the duration effects of UI, as any wage effects are small. Our results suggest that both age and short-term contribution time are indeed important determinants of UI responses, and thus relevant for policy differentiation. The welfare cost of UI could be reduced by reallocating resources towards younger workers with stable employment histories.
