Beginning in the early 1970`s, the Efficient Market Hypothesis (EMH henceforth) became very dominant in academic circles trying to understand the rules of return in the equity market. After a long period of successes, faith in this Hypothesis was gradually eroded by the discovery of several...

In this article, a model of path dependency is developed, grounded in behavioral economics (x-efficiency/efficiency wage theory), where it becomes possible and reasonable to expect a multiplicity of equilibrium solutions to identical economic problems and for the dominant solution to be...

We conduct an experiment where subjects are matched in groups of three and vote on a moral transgression. Analyzing different voting rules, the frequency of votes for the moral transgression increases with the number of votes required for it. This effect persists when considering pivotal votes...

This paper provides derivations necessary for solving an optimal consumption problem with multiplicative habits and a CRRA 'outer' utility function either for a microeconomic problem with both labor income risk and rate-of-return risk or for a macroeoconomic representative agent model.

Neoclassical economic theory rules out systematic errors in consumption choice. According to the basic view, individuals know what they choose. They are able to predict how much utility an activity or a good produces for them now and in the future and they can maximize their utility. This...

Goals are an important source of motivation. But little is known about why and how people set them. We address these questions in a model based on two stylized facts from psychology and behavioral economics: i) Goals serve as reference points for performance. ii) Present-biased preferences...

It is a puzzle why people often evaluate consequences of choices separately (narrow bracketing) rather than jointly (broad bracketing). We study the hypothesis that a present-biased individual, who faces two tasks, may bracket his goals narrowly for motivational reasons. Goals motivate because...

Unternehmen stehen im Zeichen von Wandel und Krisen wie der Corona Pandemie unter mas-sivem Handlungs- und Veränderungsdruck. Wirtschaftsskandale wie die Insolvenz von Wirecard - immerhin einem DAX Unternehmen - sorgen für zusätzlichen gesellschaftlichen Druck. Zugleich schafft die...
