I am a PhD candidate at the Department of Finance, Tilburg University. My research is centered around finance and health. I study how financial shocks affect households' and employees' health, and how health shocks impact household finances. I am also interested in the economics of family businesses.

My thesis advisors are Luc Renneboog and Julio Crego.

Household Finance under the Shadow of Cancer (job market paper)

I study the causal effects of life expectancy on financial, economic, and demographic decisions. My sample consists of individuals who undergo genetic testing for a hereditary cancer syndrome. Genetic testing randomizes tested persons into two groups. Those who test positive learn that they face a high risk of cancer and a shorter life expectancy. Those who test negative learn that their cancer risk is similar to that of the general population. The differences in outcomes between these two groups identify the effects of life expectancy. I find that life expectancy has a positive effect on wealth accumulation. Lower savings rates, safer portfolios, decreased labor supply, and different preferences for household composition explain lower wealth accumulation under reduced life expectancy.

Corporate Financing Frictions and Employee Mental Health (with Luc Renneboog)

(Conditionally accepted at the Journal of Financial and Quantitative Analysis)

This paper argues that corporate financial frictions can have an adverse effect on employee mental health, an important determinant of employee productivity. To identify the causal effects of financial frictions, we exploit variation in firms’ need to refinance their long-term debt in 2008, a period when refinancing became more difficult due to the credit crunch. Using administrative microdata, we find that antidepressant use grows significantly more among employees of firms in higher need of debt refinancing. Much of this effect occurs at employees keeping their jobs, pointing to decreased perceptions of job security as a transmission channel.

The Economic Value of Eliminating Diseases (with Julio Crego, Jens Kvaerner and Luc Renneboog)

We estimate the causal effects of 334 different types of health shocks on medical expenses, mortality, disability, labor market participation, labor earnings, and the need for nursing home care using detailed data on 6.9 million people diagnosed by medical specialists between 2013 and 2017. We quantify the benefits of eliminating diseases with distinct consequences for people of different social strata by incorporating the estimates into a standard life-cycle model. Our results reveal substantial heterogeneity in welfare gains by types of disease for different people. We discuss the potential implications of our results for the financing of medical research.
