Behavioral Economics Seminar: Self-scanning and self-control

The Behavioral Economics group at IFRO invite to open seminars with a range of subjects within Behavioral Economics.

Erik Wengström, Associate Professor at Lund University, will give the presentation Self-scanning and self-control.


Payment and checkout at retail stores are increasingly being replaced by automated systems. The most recent technological invention in this area is mobile self-scanning in which customers carry a mobile scanner while shopping. Mobile self-scanning will potentially increase customers’ attention to prices and also make it easier for them to keep track of the amount spent. Using a field experiments we test if mobile self-scanning affects consumer behavior. Consumers of two Swedish grocery stores in Sweden were allocated randomly to use a mobile self-scanner or not. In general, we find no evidence of mobile self-scanning having an effect on shopping behavior. However, we do find that effects are heterogeneous. In particular, we find that individuals with low self-control tend to spend more than other individuals, but when using a self-scanner significantly reduce their spending. Moreover, we find that individuals with low self-control are sophisticated in the sense that they are more likely to use self-scanner than individuals with high self-control.
