In a previous study the authors have identified a small core of directors who are both highly central to the entire network of German corporate boards as well as closely connected among themselves. In this note the authors provide an update of their previous results using the composition of...

We derive microscopic foundations for a well-known probabilistic herding model in the agent-based finance literature. While the model is quite robust with respect to behavioral heterogeneity, the network structure describing the very feasibility of agent interaction turns out to have a crucial...

We propose a statistical equilibrium model where the tendency for competition to equalize profit rates results in an exponential power (or Subbotin) distribution. The model supports and extends recent evidence on the Laplace distribution of firm growth rates.

Following Alfarano et al. [Estimation of agent-based models: the case of an asymmetric herding model, Comput. Econ. 26 (2005) 19–49; Excess volatility and herding in an artificial financial market: analytical approach and estimation, in: W. Franz, H. Ramser, M. Stadler (Eds.),...

The behavioral origins of the stylized facts of financial returns have been addressed in a growing body of agent-based models of financial markets. While the traditional efficient market viewpoint explains all statistical properties of returns by similar features of the news arrival process, the...

Für die sogenannte Deutschland AG war eine enge Verflechtung von Personen in Aufsichtsräten und Vorständen typisch. Diese Strukturen haben sich über die Zeit kaum geändert. Dies zeigen die Autoren mit Hilfe der Netzwerkanalyse – einer Methode, die aus den Naturwissenschaften kommend immer...
