Interacting agents in finance represent a behavioral, agent-based approach in which financial markets are viewed as complex adaptive systems consisting of many boundedly rational agents interacting through simple heterogeneous investment strategies, constantly adapting their behavior in response...

Many intertemporal trade-offs are unbalanced: while the advantages of options are concentrated in a few periods, the disadvantages are dispersed over numerous periods. We provide novel experimental evidence for "concentration bias", the tendency to overweight advantages that are concentrated in...

For non-economists, it is often difficult to understand why economists place so much emphasis on the self-interest motive. It is obvious that people act out of a variety of motives - gratitude, anger, social obligation and many, many other motives. There are several reasons why economists still...

Die Präzision ökonomischer Prognosen und die Qualität politischer Handlungsempfehlungen hängen in entscheidendem Ausmaß von der Qualität des zugrunde liegenden Verhaltensmodells ab. Nur ein empirisch gut fundiertes Modell ökonomischen Handelns erlaubt es, die Konsequenzen politischer...

In dieser Studie wird eine Auswahl an zentralen Denkfehlern bei der Geldanlage dargestellt, die aufgrund von begrenzt rationalem Verhalten getroffen werden. Auf Basis aktueller Studien aus der Verhaltensökonomik wird erklärt, wieso sich Anleger häufig falsch verhalten und was sie dagegen tun...

How do human beings make decisions when, as the evidence indicates, the assumptions of the Bayesian rationality approach in economics do not hold? Do human beings optimize, or can they? Several decades of research have shown that people possess a toolkit of heuristics to make decisions under...

That the rationality of individual people is ‘bounded’ – that is, finite in scope and representational reach, and constrained by the opportunity cost of time – cannot reasonably be controversial as an empirical matter. In this context, the paper addresses the question as to why, if...

Current time allocation and household production models face three major weaknesses: First, they only describe the average time allocation. Thus, information about the order of activities is lost. Therefore, it is impossible to describe the influence of activities on later ones. Such...
