Research Interests

The main focus of my research is on risk preferences and related concepts (ambiguity/vagueness aversion, non-linear probability weighting, investment decisions, market behavior, etc.). In my projects, I make use of several tools of economics and finance, but also embedd my findings in a framework provided by neuroscience and psychology. By doing so, I am interested in the temporal and contextual stability of preferences – disentangling preference shifts from pure noise in decisions – and how individual preferences translate into experimental market settings. Contexts range from the experimental induction of exogenous stress to inducing anticipated anxiety. My aim is to combine a model-theoretic framework with evidence from laboratory experiments to be able to base  my findings on and compare my results to predicitions of behavioral economics.

• The Impact of Stress on Risky Choice: Preference Shifts or Noise?(with Elle Parslow)
  Abstract:
  We analyze the impact of stress on risky choice in a large-scale between-subjects design with N = 194 participants. In particular, the main contribution of our work is that we are able to disentangle errors in decision making from an actual shift in preferences between our experimental treatments no-stress and stress. Acute stress is induced using the Trier Social Stress Task for Groups (TSST-G, Von Dawans et al. (2011)), risk preferences are elicited using a recent method developed by Andersson et al. (2016). Additionally controlling for cognitive reflection (CRT, Frederick (2005); Toplak et al. (2014), we analyze whether our results are driven by different levels of cognitive ability as the driver for observed noise within and between treatments. We find that, controlling for noise, risk attitudes are stable between conditions. The overall number of decision errors is low on average and does not increase under stress. Additionally, we find suggestive evidence for lower cognitive abilities being correlated with more noise in decision-making in general, however, independent of treatment.
