Inspired by findings of low–dimensional nonlinearities and the Theorem of Takens (1983) forecasting models of financial time series are often built upon nonparametric, i.e. universal nonlinear, univariate relationships. Empirical investigations, however, are seriously contaminated by the...

We estimate in this paper a non probabilistic Markovien model of stocks prices with an evolutionary selection of heterogeneous strategies. We chose to proceed by estimation relating on 27 companies from the CAC 40 and the composite index corresponding to these 27 companies to avoid the risk of...

Employing an augmented univariate EGARCH model, we estimate the dynamic impact of information arrival as measured by volume on asymmetric news in the pre and post 2009 global financial crisis in the Athens Stock Exchange (ASE). Our results reveal that trading volume appears to capture a...

La courbe de structure des taux d'interet est une des composantes fondamentales de la theorie economique et financiere. Celle-ci, en etablissant une relation entre les taux d'interet et les maturites, permet d'evaluer de nombreux actifs financiers. Or, les methodes de revelation sont nombreuses...

Bayesian Acceptance Sampling Approach is associated with utilization of prior process history for the selection of Distributions (viz., Gamma Poisson, Beta Binomial) to describe the random fluctuations involved in Acceptance Sampling. Calvin (1984) provides procedures and tables for implementing...

This paper presents evidence suggesting that artificial neural networks approach (ANNs) outperform traditional statistical methods and can forecast equity premiums reasonably well. The study replicates out-of-sample estimates of regression using ANN with economic fundamentals as inputs. The...

This paper provides evidence of integration in European equity and bond markets over the period January 2, 1997 to October 1, 2006. Our focus is to examine time-varying correlation dynamics in Euro-area, Central European (CE) and Balkans financial markets, modifying the asymmetric generalized...

Using a flexible semiparametric varying coefficient model specification, this paper examines the role of fiscal policy on the U.S. asset markets (stocks, corporate and treasury bonds). We consider two possible roles of fiscal deficits (or surpluses): as a separate direct information variable and...

The purpose of this paper is to propose a global discrete-time modeling of the term structure of interest rates which is able to capture simultaneously the following important features: (i) an historical dynamics of the factor driving term structure shapes involving several lagged values, and...

Contagion tests that are based on the correlation coefficient assume constant correlations and symmetric impacts of shocks. Moreover, they neglect volatility as a potential factor of contagion. We show that such tests can be misleading when correlations are time-varying and volatility is...
