Choice consistency and the attraction effect

The attraction effect violates consistency requirements at the heart of rational choice, but despite its profound implications it has barely attracted attention in economics. I present a laboratory experiment aimed at testing the attraction effect and at disentangling some of its explanations using novel manipulations. I find the attraction effect and I also uncover a new ‘range effect’ that runs against it. This range effect lends support to recent theories based on focusing and salience.

Preference reversals in the social domain

People prefer to give money to socially close others. I study the stability and consistency of such preferences. In an experiment, I compare preferences elicited with different but strategically equivalent methods. Social distances are measured with tools from social psychology. I find preference reversals when money benefits individuals but not when it benefits charities. Social distances explain this difference.

Explaining preference reversals across domains with a focusing model

Similar phenomena have been documented in risky choice and in intertemporal choice. I use a simple model to organise the literature and provide a common explanation to these phenomena. The model, building upon Kőszegi and Szeidl (2013), is based on a psychological mechanism: increasing the range of values of a particular attribute in the consideration set increases the weight placed on this attribute. I also show how the model can explain preferences reversals between choice and valuation, as well as different forms of context-induced reversals such as the asymmetric dominance effect. Finally, I extend the model to choice involving social distances and predict new anomalies.

Teaching

In the past I have been teaching microeconomics, mathematical economics and financial economics as a graduate teaching assistant. I am now teaching behavioural and experimental economics seminar modules. I am also supervising bachelor theses.
