We consider the psychological and social foundations of human contributions and punishments in a voluntary contributions mechanism with punishment (VCMP). We eliminate 'dynamic economic linkages' between the two stages of our "modified" VCMP to rule out other potential explanations. We use a...

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...

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...

Ambiguous prospects are ubiquitous in social and economic life, but the psychological foundations of behavior under ambiguity are still not well understood. One of the most robust empirical regularities is the strong correlation between attitudes towards ambiguity and compound risk which...

We propose a notion of r-rationality, a relative version of satisficing behavior based on the idea that, for any set of available alternatives, individuals choose one of their r-best according to a single preference. We fully characterize the choice functions satisfying the condition for any r,...

Risky health behaviors such as smoking, drinking alcohol, drug use, unprotected sex, and poor diets and sedentary lifestyles (leading to obesity) are a major source of preventable deaths. This chapter overviews the theoretical frameworks for, and empirical evidence on, the economics of risky...

Using the techniques of revealed preference analysis, we study a two-stage model of choice behavior. In the first stage, the decision maker maximizes a menu-dependent binary relation encoding preferences that are imperfectly perceived. In the second, a menu-independent binary relation is...

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...

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...
