Parametric & nonparametric approaches to event studies: an application to a hotel’s market value

The main objective of this paper is twofold: on the one hand, to analyse the impact that the announcement of the opening of a new hotel has on the performance of its chain by carrying out an event study, and on the other hand, to compare the results of two different approaches to this method: a parametric specification based on the autoregressive conditional heteroskedasticity models to estimate the market model, and a nonparametric approach, which implies employing Theil’s nonparametric regression technique, which in turn, leads to the so-called complete nonparametric approach to event studies. The results that the empirical application arrives at are noteworthy as, on average, the reaction to such news releases is highly positive, both approaches reaching the same level of significance. However, a word of caution must be said when one is not only interested in detecting whether the market reacts, but also in obtaining an exhaustive calculation of the abnormal returns to further examine its determining factors.

The cognitive mobilization index: crises and political generations

This article shows how the cognitive mobilization index, designed for use in observing potential political participation, can be used as an indicator of the political climate that a particular society is going through. Following a discussion of the theoretical elaborations (and their working definitions) of the concept of cognitive mobilization, a longitudinal study of various European countries is used to consider the question of how political crises influence cognitive mobilization indexes and what effects they have on the political socialization process among the youngest cohorts.

Remuneración al accionista en las empresas cotizadas: un análisis descriptivo 2000-2015

El presente trabajo se centra, en primer lugar, en la descripción de las distintas fórmulas de retribución al accionista utilizadas por las principales empresas españolas en los últimos años, prestando especial atención a las ventajas e inconvenientes de cada una de ellas desde diferentes puntos de vista. En la segunda parte del trabajo se lleva a cabo un análisis descriptivo de la evolución de las distintas fórmulas de retribución para las empresas cotizadas del mercado español en el periodo comprendido entre 2000 y 2015. En el mismo observamos cómo la retribución al accionista se ha ido incrementado en términos cuantitativos durante el periodo de crisis y cómo las empresas han ido diversificado sus métodos de retribución en comparación con el periodo pre-crisis donde la retribución se realizaba de forma casi exclusiva en forma de pago en efectivo.
