I studied economics at HU Berlin, University of Copenhagen and Leuphana University. In fall 2018, I was visiting the Center for Experimental Social Sciences at New York University.
I am on the academic job market 2019/2020 and I will be available for interviews at the European Job Market for Economists 2019 in Rotterdam, as well as the ASSA/AEA Annual Meeting 2020 in San Diego.
Sin Taxes and Self Control with Sinne Smed,
Social Image Concerns and Welfare Take-Up with Jana Friedrichsen and Tobias König,
Journal of Public Economics, 168, 2018, pp. 174-192. (Link)
Using a laboratory experiment, we present first evidence that social image concerns causally reduce the take-up of an individually benecial transfer. Our design manipulates the informativeness of the take-up decision by varying whether transfer eligibility is based on ability or luck, and how the transfer is financed. We find that subjects avoid the inference both of being low-skilled (ability stigma) and of being willing to live off others (free-rider stigma). Using a placebo treatment, we exclude other explanations for the observed stigma effects. Although stigma reduces take-up, elicitation of political preferences reveals that only a minority of “taxpayers” vote for the public transfer.

Do prices and purchases respond symmetrically to soft drink tax increases and cuts? Evidence from Danish tax reforms
with Sinne Smed,
R&R at Economics and Human Biology
While in January 2012, Denmark increased the long-standing tax on sugary soft drinks, the tax was cut by half in July 2013 and then completely repealed in January 2014. In this study, we examine whether increases and cuts of the soft drink tax lead to symmetric over- or under-shifting to prices and to symmetric demand responses. We use longitudinal scanner data of 1,282 Danish households to estimate within-product changes in prices and within-household changes in purchase quantity. The tax hike was overshifted by a factor of 2.2 while the tax repeal was passed through with a factor of 1.2. On average, consumption was 13.4 percent lower the year after the tax increase compared to the year before. The repeal of the tax was associated with an increase in purchase quantity of 31.0 percent. This is equivalent to price elasticities of 1.1 and 1.3 respectively. The results suggest that consumers react stronger to tax cuts than to tax increases. Furthermore, the increase in consumption following a tax cut has no limiting effect on the consumption of other beverages suggesting an increase in the intake of calories. This might have implications for health in countries that consider repealing current taxes on soft drinks.
Earn More Tomorrow: Overconfident Income Expectations and Consumer Indebtedness
with Antonia Grohmann, Lukas Menkhoff and Christoph Merkle,
CRC TRR 190 Discussion Paper No. 152. (PDF)
This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt-taking. In a lab experiment, participants can purchase goods by borrowing against their future income. We exogenously manipulate income expectations by letting income depend on relative performance in hard and easy quiz tasks. We successfully generate biased income expectations and show that participants with higher income expectations initially borrow more. Overconfident participants scale back their consumption after feedback. However, at the end of the experiment they remain with higher debt levels, which represent real financial losses. To assess the external validity, we find further evidence for the link between overcondence and borrowing behavior in a representative survey (GSOEP-IS).
