The paper examines a class of random dynamical systems related to the classical von Neumann and Gale models of economic dynamics. Such systems are defined in terms of multivalued operators in spaces of random vectors, possessing certain properties of convexity and homogeneity. We establish a...

This paper studies the role of strategy and the order book mar-ket mechanism in price dynamics and the order flow behaviour. To this end we analyse a zero-intelligence agent model of a dynamic limit order market. Stylised facts of limit order markets are shown to be influenced and, in some...

This paper introduces an expected value estimator with expert knowledge to the robust estimation of sovereign rating transitions which are characterised by few observations. Ourestimates of default premia within Mexican, Colombian and Brazilian Eurobond yield spreads provide a better fit than...
