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.

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.
