Statistical analysis of stock markets and foreign exchange markets has demonstrated the intermittent nature of economic time series. A nonlinear model of business cycles is able to simulate intermittency arising from order-chaos and chaos-chaos transitions. This monograph introduces new concepts...

Lineare und nichtlineare dynamische Systeme werden in der aktuellen wirtschaftswissenschaftlichen Forschung immer wichtiger und ermöglichen ein tieferes Verständnis sowohl für geordnete wie auch chaotische Abläufe der Konjunktur und der Finanzmärkte. Mathematische Methoden, die in den...

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...

This paper formalizes the idea that more hedging instruments may destabilize markets when traders are heterogeneous and adapt their behavior according to experience based reinforcement learning. We investigate three different economic settings, a simple mean-variance asset pricing model, a...
