Our objective in this paper is to identify the nature of the dependence or causal relationship that exists between US inflation and commodity prices using recent methods of linear cointegration, and non-linear Granger causality. The main contribution is the construction of a noisy chaotic...

In this paper, we discuss a number of univariate tests for independence and hidden nonlinear deterministic structure, and apply these tests to the Canadian exchange rate, using daily data over a 30-year period from January 2, 1973 to February 14, 2003

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...

In this paper, we further analyse the rich dynamic properties of the noisy chaotic model developed by Kyrtsou (International Journal of Bifurcation and Chaos, 2005) considering homoskedastic errors, in the aim to derive information about possible linkages between noisy chaotic dynamics and ARCH...
