How immigration affects the labor market of the host country is a topic of major concern for many immigrant-receiving nations. Spain is no exception following the rapid increase in immigrant flows experienced over the past decade. We assess the impact of immigration on Spanish natives’ income by estimating the net immigration surplus accruing at the national level and at high immigrant-receiving regions while taking into account the imperfect substitutability of immigrant and native labor. Specifically, using information on the occupational densities of immigrants and natives of different skill levels, we develop a mapping of immigrant-to-native self-reported skills that reveals the combination of natives across skills that would be equivalent to an immigrant of a given self-reported skill level, which we use to account for any differences between immigrant self-reported skill levels and their effective skills according to the Spanish labor market. We find that the immigrant surplus amounts to 0.04 percent of GDP at the national level and it is even higher for some of the main immigrant-receiving regions, such as Cataluña, Valencia, Madrid, and Murcia.

La electricidad es un elemento muy importante para la sociedad y cada vez se depende más para la vida moderna y el trabajo. Como consecuencia, el consumo de electricidad ha crecido año a año y por lo tanto, la producción también ha aumentado. Esto ha provocado que los países estén interconectados entre sí para poder satisfacer la demanda de electricidad. Esta situación ha llevado a la formación del mayor mercado a nivel global de intercambio de electricidad. Este trabajo tiene como objetivo analizar el mercado eléctrico de los países de Noruega, Suecia, Finlandia y Dinamarca y el análisis de los precios de la electricidad. Los resultados sugieren que los precios de la electricidad son muy volátiles, es por ello que en invierno la media de los precios es más alta y en verano es más baja.

[EU]Lan honetan hutsetik hasita skate motorizatu baten diseinu bat egin da, Industria Teknologian Ingeniaritzako Graduan eskuratutako jakintzak erabiliz. Skatea gazteengan oso erabilia den garraiobide bat da aisia dela-eta, eta sinpletasuna eta ekonomia kontuan hartuta, aisia eta ingurugiroarekiko konpromisoa nahasten dira diseinu honekin. Lanak bide argi bat dauka: hasieran merkatuaren egoera aztertzen da, gero diseinu posible batzuk proposatu ahal izateko, eta hortik aukera bat jorratu ahal izateko. Hortaz, prozesua hasieratik hasita, egitura hau izango du lanak: Hasteko, skate motorizatuen merkatuko egoera zein den aztertzen da, ondoren eta helburuak zeintzuk diren kontutan izanda, diseinu posible batzuk proposatu ahal izateko, alternatiben analisien atalean ageri direnak. Proposamen horiek aztertu egiten dira, alde on eta txarrak desberdinduz eta horietako soluzio bat aukeratuz. Aukeratutako diseinuaren CAD modelo bat eraikitzen da, ondoren egoera fisikoa matematikoki modelizatzeko eta beharrezko kalkuluak egin ahal izateko, metodologia atalean eta eranskinetan ageri direnak, hala nola, azelerazio jakin bat lortzeko behar den potentzia, transmisioan beharrezkoak diren kalkuluak kokatu beharreko elementuak zeintzuk diren erabaki ahal izateko, etab. Bide honetan, jorraturiko diseinuaz gain beste diseinu optimizatu eta konplexuago bat proposatzen da, ikerketa bidea zabalik duena, enpresa mundura gehiago zuzendua. Azkenik, lana burutzeko bete behar izan diren ataza bakoitzaren deskribapena eta iraupena, aurrekontua eta gastu aitorpena, arriskuen analisia eta proiektu honetatik atera ditugun ondorioak ematen dira.

[ES] Exponemos en este trabajo los primeros resultados referentes a las áreas de aprovisionamiento de materiales silíceos en el sector oriental de la Cuenca Vasco-Cantábrica durante el Pleistoceno superior y Holoceno. Se describen aquellos afloramientos cuyos sílex han sido identificados en varios yacimientos del periodo contemplado. Hemos constatado una transformación sustancial de las estrategias de aprovisionamiento, observable a fines del Paleolítico y especialmente significativa desde el Epipaleolítico. Asimismo, las pautas de ocupación del territorio reflejadas muestran indicios de un aprovechamiento rentable, estacional, de tierras en torno a los 600 m.s.n.m. durante el Pleistoceno superior, y con territorios de explotación probablemente de mayor extensión que los contemplados hasta el momento por la historiografía del Paleolítico cantábrico.

In this paper we measure the impact of regulatory measures which affected the Spanish electricity wholesale market in the period 2002-2005. Our approach is based on the fact that regulation changes firms' incentives and therefore their market behavior. In the absence of any regulation firms would choose profit- maximizing prices on their residual demands so that the observed gap between optimal and actual prices provides a measure of the effect of regulation. Our results indicate that regulation has decreased wholesale prices considerably, but became less effective at the end of the sample period which explains the change of regulatory regime introduced in 2006.

This paper estimates a standard version of the New Keynesian Monetary (NKM) model augmented with financial variables in order to analyze the relative importance of stock market returns and term spread in the estimated U.S. monetary policy rule. The estimation procedure implemented is a classical structural method based on the indirect inference principle. The empirical results show that the Fed seems to respond to the macroeconomic outlook and to the stock market return but does not seem to respond to the term spread. Moreover, policy inertia and persistent policy shocks are also significant features of the estimated policy rule.

A number of European countries, among which the UK and Spain, have opened up their Directory Enquiry Services (DQs, or 118AB) market to competition. We analyse the Spanish case, where both local and foreign firms challenged the incumbent as of April 2003. We argue that the incumbent had the ability to abuse its dominant position, and that it was a perfectly rational strategy. In short,the incumbent raised its rivals' costs directly by providing an inferior quality version of the (essential) input, namely the incumbent's subscribers' database. We illustrate how it is possible to quantify the effect of abuse in situation were the entrant has no previous history in the market. To do this, we use the UK experience to construct the relevant counterfactual, that is the "but for abuse" scenario. After controlling for relative prices and advertising intensity, we find that one of the foreign entrants achieved a Spanish market share of only half of what it would have been in the absence of abuse.

Systematic liquidity shocks should affect the optimal behavior of agents in financial markets. Indeed, fluctuations in various measures of liquidity are significantly correlated across common stocks. Accordingly, this paper empirically analyzes whether Spanish average returns vary cross-sectionally with betas estimated relative to two competing liquidity risk factors. The first one, proposed by Pastor and Stambaugh (2002), is associated with the strength of volume-related return reversals. Our marketwide liquidity factor is defined as the difference between returns highly sensitive to changes in the relative bid-ask spread and returns with low sensitivities to those changes. Our empirical results show that neither of these proxies for systematic liquidity risk seems to be priced in the Spanish stock market. Further international evidence is deserved.

This paper deals with the economics of gasification facilities in general and IGCC power plants in particular. Regarding the prospects of these systems, passing the technological test is one thing, passing the economic test can be quite another. In this respect, traditional valuations assume constant input and/or output prices. Since this is hardly realistic, we allow for uncertainty in prices. We naturally look at the markets where many of the products involved are regularly traded. Futures markets on commodities are particularly useful for valuing uncertain future cash flows. Thus, revenues and variable costs can be assessed by means of sound financial concepts and actual market data. On the other hand, these complex systems provide a number of flexibility options (e.g., to choose among several inputs, outputs, modes of operation, etc.). Typically, flexibility contributes significantly to the overall value of real assets. Indeed, maximization of the asset value requires the optimal exercise of any flexibility option available. Yet the economic value of flexibility is elusive, the more so under (price) uncertainty. And the right choice of input fuels and/or output products is a main concern for the facility managers. As a particular application, we deal with the valuation of input flexibility. We follow the Real Options approach. In addition to economic variables, we also address technical and environmental issues such as energy efficiency, utility performance characteristics and emissions (note that carbon constraints are looming). Lastly, a brief introduction to some stochastic processes suitable for valuation purposes is provided.
