I present a simple model of an evolutionary financial market with heterogeneous agents, based on the concept of adaptive belief systems introduced by Brock and Hommes (1997a). Agents choose between different forecast rules based on past performance, resulting in an evolutionary dynamics across...

While some of the recent surge of oil prices can be attributed to robust global demandat a time of tight production capacities, commentators occasionally also blame theimpact of speculators for part of the price pressure. We propose an empirical oil market model with heterogeneous speculators....

It is well documented that the U.S. employment report has a strong price impact in financial markets. Based of these precision proxies, we show that prices respond significantly stronger to more precise information, even after controlling for an asymmetric price response to ’good’ and ’bad’...

Diese Studie untersucht die formale Aussage, dass in kleinen offenen Volkswirtschaften flexible Wechselkurse eine 'sckockabsorbierende Wirkung' entfalten und exogene Störungen effektiver als feste Wechselkurse mildern. Ein intertemporales Modell mit nominalen Rigiditäten zeigt die...

Preise auf Kapitalmärkten werden durch nicht-antizipierte Informationen getrieben. Eine zentrale Aussage Baysianischer Lernmodelle impliziert, dass die Stärke der Preisreaktion einerseits von der Höhe der nicht antizipierten Komponente abhängt, andererseits aber auch von der Präzision der...

After exchanges and alternative trading venues have introduced electronic execution mechanisms worldwide, the focus of the securities trading industry shifted to the use of fully electronic trading engines by banks, brokers and their institutional customers. These Algorithmic Trading engines...

This paper proposes the Shannon entropy as an appropriate one-dimensional measure of behavioural trading patterns in financial markets. The concept is applied to the illustrative example of algorithmic vs. non-algorithmic trading and empirical data from Deutsche Börse's electronic cash equity...

Let a society's unhappiness be measured by the aggregate of the levels of relative deprivation of its members. When two societies of equal size, F and M, merge, unhappiness in the merged society is shown to be higher than the sum of the levels of unhappiness in the constituent societies when...
