I am a PhD candidate in Finance at the University of St.Gallen, Switzerland.
My research focuses on household finance and behavioral economics, particularly payment behavior. I'm working under the supervision of Martin Brown and Christian Biener. I will be on the 2024/2025 academic job market (Job market page of the University of St. Gallen).

Abstract: Despite the long-term trend away from cash and the widespread adoption and acceptance of payment cards, many people still carry considerable amounts of cash. In a pre-registered study, I examine whether risk attitudes or a preference for the timing of resolution of uncertainty can explain consumers' persistent cash holdings. To self-insure against the possibility of being unable to pay by card, risk-averse consumers are expected to hold cash in larger amounts. Moreover, consumers who overweight the small probability of card non-acceptance and those who prefer early resolution of uncertainty are also predicted to carry more cash. I test these predictions using data from the RAND American Life Panel (N=1,021) and on experimental preference data from Swiss consumers (N=1,682). 86% of U.S. and 95% of Swiss individuals carry cash in their wallets, with an average of USD 63 and CHF 94, respectively. Neither risk aversion, probability weighting, nor a preference for early resolution of uncertainty are consistently related to cash holdings. This highlights a gap in our understanding of cash management that current standard and behavioral theories do not fully address, warranting further research.
This figure displays the association between the amount of cash holdings and risk aversion (panel A and panel C), probability weighting (panel B), as well as a preference for the early resolution of uncertainty (panel D). All nonbinary variables are standardized. The sample size of the U.S. RAND American Life Panel (ALP) is N=1,021. The sample size of the Swiss insurance sample is N=1,682.

Abstract: How does the improved convenience of electronic payments affect consumer payment choice and cash demand? We study the staggered, quasi-random introduction of contactless debit cards by a retail bank. We use account-level data and compare transactions which are eligible for contactless authentication to transactions which are not. We identify a significant convenience effect on debit card use at the intensive margin. The convenience elasticity is strongest among younger clients. Treatment effects increase over time, coinciding with increasing merchant acceptance. The effect on cash demand is economically small and statistically insignificant. We also find no effect on consumer spending.

Work in progress: This research addresses the question of how young individuals pay in two parts. First, we provide a descriptive analysis that tracks the evolving payment patterns among youth and young adults, focusing on trends driven by technological advancements. Second, we explore the influence of social factors, including intergenerational effects — examining how parental background, such as education and language, shapes payment choices — and peer effects from individuals with similar backgrounds and living environments. This study, in collaboration with the Swiss National Bank, utilizes data from their three payment surveys (2017, 2020, 2022), with the most recent wave providing detailed parental background information. Preliminary results show that since 2017, young people have reduced cash usage in favor of payment apps. However, payment habits vary significantly by parental and cultural background — children whose parents primarily use cash tend to follow suit, particularly when receiving money in cash.

Abstract: The National Institute for Health and Care Excellence (NICE) in England uses quality-adjusted life years (QALYs) to assess the cost-effectiveness of treatments. A QALY is a measure that combines the size of the clinical benefit of a treatment with the time the patient benefits from it, i.e., the time horizon. We wanted to know how consistently QALY gains are calculated at NICE. Therefore, we have analysed information on the time horizons used for the QALY calculations of the concluded evaluations conducted under the Highly Specialised Technologies programme for treatments of very rare diseases at NICE. For treatments with final guidance published by December 2023 (n = 29), a time horizon of median 97.5 years (range: 35 to 125 years) was used to calculate the QALY gains. For most QALY calculations, the accepted time horizon was longer than either the expected treatment duration or the estimated life expectancy. In contrast, for the only technology with a final negative funding decision, i.e., afamelanotide for treating the lifelong chronic disease erythropoietic protoporphyria, a time horizon that was shorter than the expected treatment duration was used. The fairness and consistency of the evaluation process of treatments for very rare diseases at NICE should be reviewed.
