Self-control failures, as judged by themselves

The existence of self-control failures is often used to legitimize public policy interventions. The argument is that reducing self-control failures can make people better off, as judged by themselves. However, there is only scarce evidence on the frequency and welfare costs of self-control failures. This paper presents a survey method that allows us to measure self-control failures in everyday life and to identify their welfare costs in terms of associations with experienced subjective well-being. We present novel survey evidence using this method and discuss its implications for behavioural welfare economics and behavioural public policy.
