Behavioral economics is influencing regulatory initiatives in many nations, including the United States and the United Kingdom. The role of behavioral economics is likely to increase in the next generation, especially in light of the growing interest in low-cost, choice-preserving regulatory...

Libertarian paternalism, as advanced by Cass Sunstein, is seriously flawed, but not primarily for the reasons that most commentators suggest. Libertarian paternalism and its attendant regulatory implications are too libertarian, not too paternalistic, and as a result are in considerable tension...

Most of the empirical literature on consumption behaviour over the last decades has focused on estimating Euler equations. However, there is now consensus that data-related problems make this approach unfruitful, especially for answering policy relevant issues. Alternatively, many papers have...

Moderne Marktordnungen schützen den Verbraucher vor Schäden und sichern den Leistungswettbewerb und die Funktionsfähigkeit von Märkten. Wettbewerbsorientierte Verbraucherpolitik und verbraucherorientierte Wettbewerbspolitik ergänzen sich dabei. Die Verhaltensökonomik zeigt allerdings, dass...

This paper develops a model of choice that embeds some psychological aspects affecting decision maker's behaviour. In the model, the decision maker attaches an unobservable psychological index -representing, e.g., the level of perceived availability or the level of salience- to each alternative...

Standard economic analysis assumes that people make choices that maximize their utility. Yet both popular discourse and other fields assume that people sometimes fail to make optimal choices and thus adversely affect their own happiness. Most social sciences thus frequently describe some...

This paper has a dual purpose. First, I present a new modeling of partial naivete, and apply this to the analysis of procrastination. The decision maker is assumed to have stationary behavior and to be partially naive in the sense of perceiving that his current preferences may persist in the...
