In a health context dependency is defined as lack of autonomy in performing basic activities of daily living that require the care of another person or significant help. However, this contingency, if present, changes throughout the lifetime. In fact, empirical evidence shows that, once this...

Islamic banks are characterised by the compliance to Islamic laws and practices, the main ones being the prohibition of interest and loans trading. Remarkably, during the 2008-2009 financial crisis, when a large number of conventional banks have announced bankruptcy, no single Islamic bank...

In a global economy, shocks occurring in one market can spill over to other markets. This paper investigates the impact of oil shocks and stock markets crashes on correlations between stock and oil markets. We test changes in correlations at different scales with non-overlapping confidence...

Recently, Leisen and Lijoi (2011) introduced a bivariate vector of random probability measures with Poisson-Dirichlet marginals where the dependence is induced through a Lévy's Copula. In this paper the same approach is used for generalizing such a vector to the multivariate setting. Some...

In this paper comparisons of allocation policies of components in two-parallel-series systems with two types of components are provided with respect to both, the hazard rate and the reversed hazard rate orders. The main results indicate that the life of this kind of system is stochastically...

GARCH models include most of the stylized facts of financial time series and they have been largely used to analyze discrete financial time series. In the last years, continuous time models based on discrete GARCH models have been also proposed to deal with non-equally spaced observations, as...

A new computational algorithm for estimating the smoothing parameters of a multidimensional penalized spline generalized model with anisotropic penalty is presented. This new proposal is based on the mixed model representation of a multidimensional P-spline, in which the smoothing parameter for...

Demand for redistribution has been traditionally investigated within a static scenario, giving the perception of a stationary association between individual determinants and preferences. Using repeated cross-sectional survey data from the General Social Survey over the period 1978{2010, we model...

We provide a comprehensive picture of the relationship between labor market outcomes and age by gender in all the 28 European countries covered by the European Statistics on Income and Living Conditions (EU-SILC). The analysis is based on a somewhat unconventional approach that refers to...

We use an asymmetric dynamic conditional correlation (ADCC) GJR-GARCH model to estimate the time-varying volatilities of financial returns. The ADCC-GJR-GARCH model takes into consideration the asymmetries in individual assets volatilities, as well as in the correlations. The errors are modeled...
