Dedication to Ole Due
It is a great pleasure for me to write a few words in tribute to my former colleague and friend Ole Due. Over the past three decades, as a civil servant, a teacher, a judge, and President of the EC Court of Justice, Ole Due has strived and succeeded in making a substantial and valuable contribution to the development and understanding of European Community law
Intergenerational social mobility in Spain between 1956 and 2011: the role of educational expansion and economic modernisation in a late industrialised country
This article explores intergenerational class mobility patterns and the role played by education in Spain usingcounterfactuals. Both men and women born from 1926 to 1981 are analysed, meaning the study covers a periodof profound economic and educational advances in a late-industrialised country. The results suggest that, amongthe cohorts born in the 1970s, men have experienced a slight increase in socialfluidity, while women haveexperienced a substantial increase that seems partially driven by their massively increased access to routine non-manual positions independent of their social origins. Inequality of educational opportunities and class returns toeducation have declined, whereas the direct effect of social origins (DESO) has remained constant for men andhas decreased considerably for women. The counterfactual analysis shows that the slight increase in socialfluidity for men is mainly driven by educational expansion. For women, theDESOand educational expansionaccount for a great share of increasingfluidity. Therefore, certain assumptions made by theModernization TheoryandGoldthorpeâs Theory of Social Mobilitycan be put into questio
Tourism in Azores Islands: Persistence in the Monthly Arrivals
This study analyses the persistence in the international monthly arrivals to the Azores Islands using a model based on fractional integration and seasonal autoregressions. The estimated fractional differencing parameter gives an indication of the long run evolution of the series. We use both aggregate data and disaggregate monthly data by location of origin and island destination. The results show that the aggregate series corresponding to the total number of arrivals is a nonstationary I(d) process with d above 1, and the most persistent ones are those travelling to SĂ€o Miguel, especially from Holland, Finland, Norway, Germany, Denmark and the UK.Monthly arrivals; Seasonal fractional integration; Persistence; Azores Islands.
Unemployment hysteresis, structural changes, non-linearities and fractional integration in Central and Eastern Europe
In this paper we aim to analyse the dynamics of unemployment in a group of Central and Eastern European Countries (CEECs). The CEECs are of special importance for the future of the European Union, given that most of them have recently become member states, and labour flows have been seen to rise with their accession. By means of unit root tests incorporating structural changes and nonlinearities, as well as fractional integration, we find that the unemployment rates for the CEECs are mean reverting processes, which is consistent with the NAIRU hypothesis, although shocks tend to be highly persistent.Unemployment, NAIRU, hysteresis, unit roots, fractional integration
Unemployment hysteresis, structural changes, non-linearities and fractional integration in European transition economies
In this paper we aim to analyse the dynamics of unemployment in a group of Central and Eastern European Countries (CEECs).

Further evidence on the PPP analysis of the Australian dollar: non-linearities, fractional integration and structural changes
The aim of this paper is to analyse the empirical fulfilment of the Purchasing Power Parity (PPP) theory for the Australian dollar. In order to do so we have applied recently developed unit root tests that account for asymmetric adjustment towards the equilibrium (Kapetanios et al., 2003) and fractional integration in the context of structural changes (Robinson, 1994, and Gil-Alana, 2008). Although our results point to the rejection of the PPP hypothesis, we find that the degree of persistence of shocks to the Australian dollar decreases after the 1985 currency crisis.PPP, Real Exchange Rate, Unit Roots, Non-linearities, Fractional integration
The lifetime problem of evaporating black holes: mutiny or resignation
It is logically possible that regularly evaporating black holes exist in
nature. In fact, the prevalent theoretical view is that these are indeed the
real objects behind the curtain in astrophysical scenarios. There are several
proposals for regularizing the classical singularity of black holes so that
their formation and evaporation do not lead to information-loss problems. One
characteristic is shared by most of these proposals: these regularly
evaporating black holes present long-lived trapping horizons, with absolutely
enormous evaporation lifetimes in whatever measure. Guided by the discomfort
with these enormous and thus inaccessible lifetimes, we elaborate here on an
alternative regularization of the classical singularity, previously proposed by
the authors in an emergent gravity framework, which leads to a completely
different scenario. In our scheme the collapse of a stellar object would result
in a genuine time-symmetric bounce, which in geometrical terms amounts to the
connection of a black-hole geometry with a white-hole geometry in a regular
manner. The two most differential characteristics of this proposal are: i) the
complete bouncing geometry is a solution of standard classical general
relativity everywhere except in a transient region that necessarily extends
beyond the gravitational radius associated with the total mass of the
collapsing object; and ii) the duration of the bounce as seen by external
observers is very brief (fractions of milliseconds for neutron-star-like
collapses). This scenario motivates the search for new forms of stellar
equilibrium different from black holes. In a brief epilogue we compare our
proposal with a similar geometrical setting recently proposed by Haggard and
Rovelli.Comment: 20 pages, 2 figures; v2: published version, references adde
AceptaciĂłn de la herencia AB intestato deferida en favor de la Generalitat Valenciana
El presente artĂculo trata de analizar si es necesario que la Generalitat Valenciana realice un acto de aceptaciĂłn expresa o tĂĄcita de la herencia intestada a que es llamada, o si por el contrario se produce a su favor la adquisiciĂłn ipso iure de la herencia. Se analizan las fases de la herencia, la condiciĂłn en que la Generalitat Valenciana es llamada a la sucesiĂłn intestada de los valencianos y las condiciones necesarias para adquirir los bienes hereditarios
