Abstract El Banco de Barcelona se creó en 1844 alrededor de un grupo de individuos que, hacia mediados de la década de 1850, tenían establecida una amplia red social conformada a través de las inversiones del grupo en las principales sociedades anónimas de la época ((Badia-Miró, Blasco-Martel, Lozano, & Soler, 2013) y (Badia-Miro, Blasco-Martel, Lozano,…
ABSTRACT: The identification of asymmetric conditional heteroscedasticity is often based on sample cross-correlations between past and squared observations. In this paper we analyse the effects of outliers on these cross-correlations and, consequently, on the identification of asymmetric volatilities. We show that, as expected, one isolated big outlier biases the sample cross-correlations towards zero and hence could hide true leverage…
ABSTRACT: Classical option pricing models are not well suited to the valuation of executive stock options (ESOs) and their incentive effects. The special characteristics of ESOs make standard methods difficult to apply to these options. The Wu-Lin model is a completely analytical expression based on the common feature of attaching performance targets to option vesting….
Abstract Nowadays copulas are extensively used in economic and finance applications, with the Gaussian copula being very popular despite ruling out non-linear dependence, particularly in the lower tail. We derive computationally simple and intuitive expressions for score tests of Gaussian copulas against Generalised Hyperbolic alternatives, which include the symmetric and asymmetric Student t, and Hermite polynomial expansions. We…
