Innerhalb der ersten Förderphase ist von den Forschungsdatenzentren der Statistischen Ämter des Bundes und der Länder eine Dateninfrastruktur geschaffen worden, die umfangreiche wissenschaftliche Analysen amtlicher Mikrodaten aus allen Bereichen zulässt. In diesem Aufsatz wird insbesondere...

Verbraucherpolitische Maßnahmen müssen dort ansetzen, wo sich Verbraucher nicht selbst schützen können. Notwendige Bedingung für eine effektive Gestaltung verbraucherpolitischer Maßnahmen ist daher das Wissen um das tatsächliche Verhalten von Verbrauchern. Gerade im Bereich...

Two econometric issues arise in the estimation of complete systems of producer or consumer demands when many non-negativity constraints are binding for a large share of observations, as frequently occurs with micro-level data. The first is computational. The econometric model is essentially an...

Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

This paper surveys recent experimental and field evidence on the impact of concerns for fairness, reciprocity and altruism on economic decision making. It also reviews some new theoretical attempts to model the observed behavior.

This paper studies the effects of social comparison on risk taking be- havior. In our framework, decision makers evaluate the consequences of their choices as changes with respect to both their own and their peers' conditions. We test experimentally whether different positions in the social...

Over the past years crowdfunding emerged as an alternative funding channel for entrepreneurs. In contrast to traditional financiers (banks, venture capital firms or angel investors), crowdfunding allows individuals to fund entrepreneurs directly even with small amounts. We received...

We conduct a modified dictator game in order to analyze the role self-image concerns play in other-regarding behavior. While we generally follow Konow (2000), a cognitive dissonance-based model of other-regarding behavior in dictator games, we relax one of its assumptions as we allow for...

In a less widely known contribution, Béla Martos (1966, Hungarian Academy of Sciences) introduced a generalized notion of concavity that is closely related to what is nowadays known as r-concavity in the operations research literature, and that is identical to what is nowadays known as...
