Long memory in return structures from developed markets

[En]The present study aimed at investigating the existence of long memory properties in ten developed stock markets across the globe. When return series exhibit long memory, the series realizations are not independent over time and past returns can help predict future returns, thus violating the market efficiency hypothesis. It poses a serious challenge to the supporters of random walk behavior of the stock returns indicating a potentially predictable component in the series dynamics. We computed Hurst-Mandelbrot’s Classical R/S statistic, Lo’s statistic and semi parametric GPH statistic using spectral regression. The findings suggest existence of long memory in volatility and random walk for logarithmic return series in general for all the selected stock market indices. Findings are in line with the stylized facts of financial time series.

The Economics of "Why is it so hard to save a threatened Language?"

We study the language choice behavior of bilingual speakers in modern societies, such as the Basque Country, Ireland andWales. These countries have two o cial languages:A, spoken by all, and B, spoken by a minority. We think of the bilinguals in those societies as a population playing repeatedly a Bayesian game in which, they must choose strategically the language, A or B, that might be used in the interaction. The choice has to be made under imperfect information about the linguistic type of the interlocutors. We take the Nash equilibrium of the language use game as a model for real life language choice behavior. It is shown that the predictions made with this model t very well the data about the actual use, contained in the censuses, of Basque, Irish and Welsh languages. Then the question posed by Fishman (2001),which appears in the title, is answered as follows: it is hard, mainly, because bilingual speakers have reached an equilibrium which is evolutionary stable. This means that to solve fast and in a re ex manner their frequent language coordination problem, bilinguals have developed linguistic conventions based chie y on the strategy 'Use the same language as your interlocutor', which weakens the actual use of B.1

Valuing a Natura 2000 network site to inform land use options using a discrete choice experiment: An illustration from the Basque Country

One of the main problems that public institutions face in the management of protected areas, such as the European Natura 2000 network, is determining how to design and implement sustainable management plans that account for the wide range of marketed and non-marketed benefits they provide to society. This paper presents an application of a stated preference valuation approach aimed at evaluating the social preferences of the population of the Basque Country, Spain, for the key attributes of a regional Natura 2000 network site. According to our results, individuals’ willingness-to-pay (WTP) is higher for attributes associated with non-use values (native tree species and biodiversity conservation) than for attributes associated with use values (agricultural development and commercial forestry). The paper concludes that management policies related to Natura 2000 network sites should account for both for the importance of non-use values and the heterogeneity of the population's preferences in order to minimize potential land use conflicts.

Natura-eremu babestuen balorazio ekonomikoa Euskal Herrian: berrikusketa bibliografiko bat

[EUS[ Ingurumen-ondasun eta zerbitzuen gaineko balorazio ekonomikoa ebaluazio-tresna erabilgarri gisa azal daiteke, bereziki natura-eremu babestuen (NEB) politikak gero eta garrantzi handiagoa eskuratzen duen testuinguruetan. Nahiz eta NEBen gaineko balorazio ekonomikoak tradizio luzea duen, Euskal Herriko NEBen gain egindakoak oraintsukoak dira. Artikulu honek balorazio ekonomiko horiek jasotzen dituzten ikerlanen berrikusketa bibliografikoa egiten du. Egindako azterketak disparekotasun nabarmena azaltzen du emaitzei dagokienez, zeinak neurri handian balorazio-ariketetan definitutako ingurumen-ondasun eta erabilitako metodologien menpe dauden. Horrekin batera, NEBen izendatze eta garapenean arrazoi ekonomikoez gain beste era batzuetako arrazoiak kontuan hartzeko beharra ere azpimarratzen da.

INTERPOL's surveillance network in curbing transnational terrorism

This paper investigates the role that INTERPOL surveillance – the Mobile INTERPOL Network Database (MIND) and the Fixed INTERPOL Network Database (FIND) – played in the War on Terror since its inception in 2005. MIND/FIND surveillance allows countries to screen people and documents systematically at border crossings against INTERPOL databases on terrorists, fugitives, and stolen and lost travel documents. Such documents have been used in the past by terrorists to transit borders. By applying methods developed in the treatment-effects literature, this paper establishes that countries adopting MIND/FIND experienced fewer transnational terrorist attacks than had they not adopted MIND/FIND. Our estimates indicate that, on average, during 2008–2011, adopting and using MIND/FIND results in 1.23 fewer transnational terrorist incidents each year per 100 million people. Thus, a country like France with a population just above 64 million people in 2008 would have 0.79 fewer transnational terrorist incidents per year owing to its use of INTERPOL surveillance. For most treatment countries, this amounts to a sizeable proportional reduction of about 60 per cent.

Estudio de la situación actual en las empresas de producción fotovoltaica

[ES]La energía solar fotovoltaica es un sistema de generación eléctrica cada vez más importante entre los países desarrollados. En este contexto, España siempre ha sido una de los países que más ha invertido a lo largo de su historia. En los últimos años, sin embargo, por culpa del déficit tarifario esta situación ha cambiado, implantando medidas para ahorrar costes que a largo plazo deterioran dicho sector. En el trabajo, se presenta un estudio que muestra la actualidad de este tejido empresarial. Para ello, se ha realizado una encuesta a varias empresas, sobre la situación del sector y las perspectivas de crecimiento y desarrollo dentro de ese entorno. Así, se ha concluido con algunas de las consecuencias que pueden suceder debido al cambio de legislación.

Segregation: theoretical approach. an empirical analysis of gender segregation in undergraduate studies at the University of the Basque Country.

The aim of this study is to analyze the gender segregation in undergraduate studies in the University from Basque Country (UPV/EHU). We use data from UPV/EHU for the period 2003-2013. We focus on the period from 2003 to 2013 to analyze the changes in the segregation over ten years. We analyze the tendencies of the men and the women inside undergraduate studies. Undergraduate studies are decomposed into five fields: Legal and social sciences, experimental sciences, engineering, arts and humanities, and health sciences. We draw segregation curves and compute the Gini segregation index within the Lorenz approach. Our results show that the gender segregation in undergraduate studies in the UPV/EHU has decreased from 2003 to 2013.
