This note is concerned with two recent agent-based models of speculative dynamics from the literature, one by Gaunersdorfer and Hommes and the other by He and Li. At short as well as long lags, both of them display an autocorrelation structure in absolute and squared returns that comes...

Simulations of agent-based models have shown that the stylized facts (unit-root, fat tails and volatility clustering) of financial markets have a possible explanation in the interactions among agents. However, the complexity, originating from the presence of non-linearity and interactions, often...

Viele aktive Entscheidungen bei der Anlage in Wertpapieren werden auf Basis von Informationen getroffen, die mit Hilfe empirischer Analysen historischer Finanzdaten gewonnen wurden. Leider sind die meisten Ergebnisse dieser Analysen sehr anfällig gegenüber einer Änderung der Zeitparameter,...

This paper considers a simple Continuous Beliefs System (CBS) toinvestigate the effects on price dynamics of several behavioralassumptions: (i) herd behaviour; (ii) a-synchronous updating ofbeliefs; and (iii) heterogeneity in time horizons (memory) amongagents. The recently introduced concept of...
