Real-world consumers, though, are motivated by more than incentives and information (Michalek et al. 2015). These are innovative policy tools that are designed with a specific focus on behavioral factors 1 Most economist readers can be assumed to be familiar with the key insights of Behavioral Economics; those interested in the details may be referred to the excellent surveys by Camerer and Loewenstein (2004) and Della Vigna (2009). Van den Bergh et al. (2000) give an outline of behavioral economics insights with a focus on their relevance for environmental economics prior to Nudge. The contributions by Norton et al. (1998) and Söderbaum (1994) are particularly interesting as precursors of the nudge agenda, as they argue that environmental policies should try to exploit endogenous preference change. 2 An important exception to that rule was Jack Knetsch, see, e.g. Knetsch and Sinden (1984), Knetsch (1989 and structured. To nudge someone is to deliberately intervene in a given CA. Nudges are widely regarded as potential complements to more traditional incentive-based regulation; the hope is that adding them to the policy mix may be both more effective and more popular among the general public than relying on traditional regulatory tools alone (Thaler and Sunstein 2008: ch. 12). 6 As Cass Sunstein (2014: 13) puts it, the general aim is to develop "sensible, low-cost policies with close reference to how human beings actually think and behave." There is an important caveat, though: Due to their unclear welfare foundations and the potentially paternalistic and manipulative way in which these tools shape human behavior (viz., by addressing and exploiting cognitive biases), nudges raise complex ethical questions.

Documents in EconStor mayThe exact definition of nudges is a matter of some controversy. What's typically offered as a back-of-the-envelope definition -"interventions that influence people's behavior without significantly changing their monetary incentives or coercing them" -is unhelpful, as it also lets the mere provision of information count as a nudge. We rather suggest to follow Hansen (2016) by supplementing this shorthand with the notion, originally advanced by Thaler and Sunstein (2008: 8) To illustrate, the subsidy and tax schemes discussed by Allcott and Taubinsky (2015) in the context of energy efficiency policy qualify as BEP in our sense of the term. 5 See in particular (ibid.: ch. 12) on green nudging, and Sunstein (201...
