Recent empirical studies have shown that the chaotic behaviour and excess volatility of financial series are the result of interactions between heterogeneous investors. In our article, we propose verifying this hypothesis. Thus, we use the Chen, Lux, and Marchesi (2000) model to show that the...

In this work we employ the Recurrence Quantification Analysis (RQA) framework, effective in discovering evidence of non-linear determinism and complex dynamics in short, noisy and irregular signals. We apply RQA to a set of US macroeconomic time series and simulated sequences in order to provide...

The objective of this paper is to examine causality and feedback relationships between primary commodity prices and US inflation. To this end, the bivariate noisy Mackey-Glass process recently developed by Kyrtsou and Labys (2006) has been applied to assess this relationship. Results obtained...

Recent empirical researches have examined the relationship between US short-term interest rates using linear as well nonlinear econometric tools. The main objective of this paper is to employ a new dynamic model that combines the bivariate noisy Mackey-Glass and the BEKK GARCH processes...
