I am a senior researcher at the Vienna Center for Experimental Economics of the University of Vienna. I am also lab manager of our lab, along with Philipp Külpmann.

You can access my full CV here.

I have put together a list of resources that I have found helpful when starting in academia. If you know any other, please let me know.

The attraction effect and its explanations
The attraction effect violates choice consistency, one of the central assumptions of economics. I present a risky choice experiment to test it and disentangle some of its explanations. I find the attraction effect, but in a smaller magnitude than previously thought. I uncover a ‘range effect’ that shows that people weight more attributes whose range increases. I also show that the aggregate results hide considerable heterogeneity between subjects

Range effect and preference reversals across domains
Similar anomalies have been documented in risky choice and intertemporal choice. I explain the similarity with the range effect, which says that people care more about attributes that differ more in their choice set. The range effect explains the common ratio effect, the common difference effect, and the magnitude effect. It also provides a characterisation of procedural preference reversals between choice and valuation. Finally, I apply the model to social distances and predict new anomalies, one of which I confirm in a laboratory experiment.
