We present a simple financial market model with interacting chartists and fundamentalists. Since some of these speculators only become active when a certain misalignment level has been crossed, the dynamics are driven by a discontinuous piecewise linear map. The model endogenously generates...

We develop a financial market model with interacting chartists and fundamentalists that embeds the famous bull and bear market model of Huang and Day as a special case. Their model is given by a one-dimensional continuous piecewise-linear map. Our model, on the other hand, is more flexible and...

The object of the work is to perform the global analysis of the Cournot duopoly model with isoelastic demand function and unit costs, presented in Puu (1991). The bifurcation of the unique Cournot fixed point is established, which is a resonant case of the Neimark-Shacker bifurcation. New...

The object of this work is to perform the global analysis of a new duopoly model which couples the two points of view of Cournot and Stackelberg. The Cournot model is assumed with isoelastic demand function and unit costs. The coupling leads to discontinuous reaction functions, whose...

Der vorliegende Aufsatz untersucht die Ursachen von Finanzmarktkrisen anhand entsprechender Vorkommnisse in Thailand, Mexiko und Tschechien, um risikoreiche Konstellationen für Emerging Markets zu identifizieren. Als Modell wurde der Ansatz von Sachs/Tornell/Velasco (1996) gewählt, der durch...

Die weltweite Finanzmarktkrise beruht zu einem wesentlichen Teil auf dem Handel mit Verbriefungen, deren Risiken aufgrund manipulierter Ratings erheblich unterschätzt wurden. Die Ursachen der Krise sind demnach weitgehend unstrittig; das Ausmaß der Krise lässt sich aber gegenwärtig kaum...
