Holidays, weekends and range-based volatility
2020
Abstract This study analyses the effect of non-trading periods on the forecasting ability of S&P500 index range-based volatility models. We find that volatility significantly diminishes on the first trading day after holidays and weekends, but not after long weekends. Our findings indicate that models that include autoregressive terms that interact with dummies that allow us to capture changes in volatility levels after interrupting periods provide greater explanatory power than simple autoregressive models. Therefore, the shorter the length of the non-trading periods between two trading days, the higher the overestimation of the volatility if this effect is not considered in volatility for…

Arbitrage opportunities and event impacts on Spanish rights issues
2022
In equity offerings in which pre-emptive subscription rights are issued, there are two ways of acquiring the company's shares: either by buying them directly on the market, or by subscribing to the new shares using the subscription rights. This could lead to the existence of arbitrage opportunities. In addition, the announcement of these processes incorporates very relevant information to the market, which could generate abnormal returns for the shares. This paper analyses both hypotheses simultaneously on the same sample and concludes that there are indeed arbitrage opportunities and also abnormal returns can be detected. Furthermore, it is also concluded that these effects are especially …

España tiene unas de las tasas más altas de paro y de fracaso y abandono escolar de la Unión europea (UE), a pesar de ser considerada la cuarta economía de la eurozona.

El procés d'informació i orientació professional: aproximació al perfil de l'orientador
2008
Durant els últims anys, el concepte d'educació permanent, també anomenat Life Long Learning, ha estat objecte de debat en el disseny de polítiques i accions educatives a Europa.

Well-Being without Employment? Promoting the Employability of Refugees
2020
There are more than 25 million refugees in the world. Many of them try to reach the Mediterranean in order to enter Europe. Spain is one of the countries that receive refugees and have to integrate them. Many refugees have experienced persecution in their countries, as well as forced migration, rape, diseases, etc. Their integration requires support and coordination from the government, health services, and social agents. The first step in achieving this integration is getting a job, which is currently an important issue. Thus, we aim to analyze the employability of a specific group of refugees in Spain and then develop and implement an intervention program to improve their employability. O…

Valutazioni interscalari nel processo perequativo del PRG di Siracusa
2016
La questione abitativa è tornata ad essere cruciale per assicurare una maggiore equità sociale, aumentando la coesione sociale e riducendo le diseguaglianze all’interno dei sistemi metropolitani o territoriali che, nell’attuale congiuntura di grave crisi economica, devono comunque rispondere alle sfide globali di sviluppo, innovazione e sostenibilità. Questo studio si propone di costruire un sistema di conoscenze sulle condizioni di accesso alla casa a scala territoriale attraverso cui individuare le criticità locali dei problemi abitativi che potrebbero essere risolti attraverso i tradizionali strumenti di pianificazione o attraverso nuove pratiche di Social Housing che coinvolgono soggett…
Volatility transmission patterns and terrorist attacks
2009
The objective of this study is to analyze volatility transmission between the US and Eurozone stock markets considering the effects of the September 11, March 11 and July 7 financial crises. In order to do this, we use a multivariate GARCH model and take into account the asymmetric volatility phenomenon, the non-synchronous trading problem and the crises themselves. Moreover, a graphical analysis of the Asymmetric Volatility Impulse-Response Functions (AVIRF) is introduced, which takes into consideration the crisis effect. Results suggest that there is bidirectional and asymmetric volatility transmission and show the different impact that terrorist attacks had on both markets. El objetivo d…
