Agent based models take into account limited rational behaviour of individuals acting on financial markets. Explicit simulation of this behaviour and the resulting interaction of individuals provide a description of aggregate financial market time series. At least for some parameter settings,...

In this paper we explore ways that alleviate problems of nonparametric (artificial neural networks) and parametric option pricing models by combining the two. The resulting enhanced network model is compared to standard artificial neural networks and to parametric models with several historical...

Game theoretic studies of market equilibria are usually noncooperative, but every exchange is a cooperative interaction, so this approach is unavoidably incomplete. One mixed cooperative-noncooperative approach that allows for this is the "biform game" approach, in which agents choose...
