Still in the Era of Area Studies? Political-Scientific Perspectives on European Competition Policy in the 2000s

This note reviews the political-scientific literature on European competition policy (ECP) in the 2000s. Based on a data set extracted from four well-known journals, and using an upfront methodology and explicit criteria, it analyzes the literature both quantitatively and qualitatively. On the quantitative side, it shows that, although a few sub-policy areas are still neglected, ECP is not the under-researched policy it used to be. On the qualitative side, the literature has greatly improved since the 1990s: Almost all articles now present a clear research question, and most advance specific theoretical claims/hypotheses. Yet, improvements can be made on research design, statistical testing, and, above all, state-of-the-art theorizing (e.g. in the game-theoretical treatment of delegation problems). Indeed, it is paradoxical that ECP specialists do not pay more attention to theoretical questions which are so central to the actual policy area they study.

Are Dictators Immune to Human Rights Shaming?

This paper examines whether human rights naming and shaming destabilizes the rule of authoritarian leaders. We argue that human rights shaming can destabilize autocratic leaders by signaling international disapproval to elites in the targeted country, increasing their capacity to replace the incumbent. In personalist regimes, shaming increases the risk of irregular exit because regime elite do not have a means to peacefully replace the incumbent. Shaming campaigns also decrease foreign aid and international trade in personalist regimes, denying the leader access to resources to pay his coalition – further destabilizing his rule. In non-personalist regimes where parties or the military allow elites to peacefully replace incumbents, human rights shaming increases the risk of regular turnover of power, but has little effect on the risk of irregular exit or international flows of aid and trade. These findings have implications for understanding when and where shaming campaigns are likely to reduce or deter repression.

Competition between TV platforms

The aim of this paper is to identify the factors that affect the market penetration of pay television by studying the competition that exists between three types of technology (satellite, cable and ADSL). We distinguish three groups of factors: the level of market competition, the level of competition in the industry and the quality of the product being offered. Our results seem to indicate that as market concentration increases, the television service can achieve greater penetration. This relationship is specifically captured by the level of intra- and inter-platform competition. We also examine the relationship between free television channels and pay television and find that as the amount of time dedicated to the broadcasting of advertising by the former increases, the number of subscribers to pay TV rises. Finally, we examine product quality by introducing the effect of holding the rights to broadcast Professional Football League matches and an HBO or Showtime produced series. Our results suggest that these variables are critical for the penetration of pay television.

Emissions distribution in post-Kyoto international negotiations: a policy

An abundant scientific literature about climate change economics points out that the future participation of developing countries in international environmental policies will depend on their amount of pay offs inside and outside specific agreements. These studies are aimed at analyzing coalitions stability typically through a game theoretical approach. Though these contributions represent a corner stone in the research field investigating future plausible international coalitions and the reasons behind the difficulties incurred over time to implement emissions stabilizing actions, they cannot disentangle satisfactorily the role that equality play in inducing poor regions to tackle global warming. If we focus on the Stern Review findings stressing that climate change will generate heavy damages and policy actions will be costly in a finite time horizon, we understand why there is a great incentive to free ride in order to exploit benefits from emissions reduction efforts of others. The reluctance of poor countries in joining international agreements is mainly supported by historical responsibility of rich regions in generating atmospheric carbon concentration, whereas rich countries claim that emissions stabilizing policies will be effective only when developing countries will join them.Scholars recently outline that a perceived fairness in the distribution of emissions would facilitate a wide spread participation in international agreements. In this paper we overview the literature about distributional aspects of emissions by focusing on those contributions investigating past trends of emissions distribution through empirical data and future trajectories through simulations obtained by integrated assessment models. We will explain methodologies used to elaborate data and the link between real data and those coming from simulations. Results from this strand of research will be interpreted in order to discuss future negotiations for post Kyoto agreements that will be the focus of the next. Conference of the Parties in Copenhagen at the end of 2009. A particular attention will be devoted to the role that technological change will play in affecting the distribution of emissions over time and to how spillovers and experience diffusion could influence equality issues and future outcomes of policy negotiations.

Heterogeneity across immigrants in the Spanish labour

The purpose of this paper is to analyze the diferences that immigrants have in the Spanish labour market. Immigrants in Spain come from a diversity of continents (Africa, South America, Eastern Europe, Asia, etc.), and there are substantial diferences in characteristics not only among continents but also among countries in each continent. Using a quantile regression method of decomposition we estimate these diferences that are reflected in the labour market and in particular are mirrored in the wage, so some immigrants are more discriminated or segregated that others because they have less advantage. For example Argentineans and Peruvians have the same origin and culture but we can find diferences in the wage that they receive in the Spanish labor market, or for example Moroccans have a advantage with respect to the Rest of Africans, due to the geographical proximity to Spain. So when we study the pay gap and the gender pay gap we need to take into consideration the origin of immigrants. We also want to study how the integration of immigrants evolved across years, whether the wage gap that we find in the first episode of work between immigrants and natives disappears or continues to be present in the Spain labour market.

Is the Spanish Inheritance and Gift Tax incompatible with the free movement of workers and capital?: The reasoned opinion of the EU Commission IP/10/513

The aim of my speech is answering to the question if the Spanish Inheritance and Gift Tax is incompatible with the free movement of workers and capital. We are going to pay special attention to the European Commission’s request to Spain to change its Inheritance and Gift Tax provisions for Non-Residents or Assets held abroad. In order to answer to the question mentioned above five points will be explained. At first place I am going to describe the infrengement procedure established in the Article 258 that the EU Commission can follow when a Member State doesn’t comply with Community Law. At second place, we are going to explain what is the content of the EU Commission delivered on 5th of may 2010 regarding the spanish Inheritance and Gift Tax. Then, we will analise what establishes the Community Law regarding the freedom of workers and capital and how they are understood by the EU Court of Justice in similar cases. Finally, we are going to provide possible amendments that Spain could undertake.

Dispositius nanoplasmònics basats en polaritons anti-simètrics per apliacacions biosensores i nanofotòniques

Presentem un estudi teòric comparatiu de les sensibilitats en volum dels sensors d’índex de refracció basats en polaritó de plasmó superficial (SPP) i en ressonància localitzada de plasmó superficial (LSPR). Els resultats demostren que el sensor SPP, àmpliament conegut i comercialitzat, ofereix una major sensibilitat en volum comparada amb la del sensor LSPR, estant aquest últim basat en l’ús de nanorods d’or. A més, la figura de mèrit del sensor LSPR, emprada per a analitzar la seva capacitat sensora, exhibeix una regió sensora òptima quan la longitud d’ona de ressonància es troba propera a 700 nm.

Dinàmica de sistemes mesoscòpics amb correlacions quàntiques mitjançant la formulació de de Broglie-Bohm

Per a determinar la dinàmica espai-temporal completa d’un sistema quàntic tridimensional de N partícules cal integrar l’equació d’Schrödinger en 3N dimensions. La capacitat dels ordinadors actuals permet fer-ho com a molt en 3 dimensions. Amb l’objectiu de disminuir el temps de càlcul necessari per a integrar l’equació d’Schrödinger multidimensional, es realitzen usualment una sèrie d’aproximacions, com l’aproximació de Born–Oppenheimer o la de camp mig. En general, el preu que es paga en realitzar aquestes aproximacions és la pèrdua de les correlacions quàntiques (o entrellaçament). Per tant, és necessari desenvolupar mètodes numèrics que permetin integrar i estudiar la dinàmica de sistemes mesoscòpics (sistemes d’entre tres i unes deu partícules) i en els que es tinguin en compte, encara que sigui de forma aproximada, les correlacions quàntiques entre partícules. Recentment, en el context de la propagació d’electrons per efecte túnel en materials semiconductors, X. Oriols ha desenvolupat un nou mètode [Phys. Rev. Lett. 98, 066803 (2007)] per al tractament de les correlacions quàntiques en sistemes mesoscòpics. Aquesta nova proposta es fonamenta en la formulació de la mecànica quàntica de de Broglie– Bohm. Així, volem fer notar que l’enfoc del problema que realitza X. Oriols i que pretenem aquí seguir no es realitza a fi de comptar amb una eina interpretativa, sinó per a obtenir una eina de càlcul numèric amb la que integrar de manera més eficient l’equació d’Schrödinger corresponent a sistemes quàntics de poques partícules. En el marc del present projecte de tesi doctoral es pretén estendre els algorismes desenvolupats per X. Oriols a sistemes quàntics constituïts tant per fermions com per bosons, i aplicar aquests algorismes a diferents sistemes quàntics mesoscòpics on les correlacions quàntiques juguen un paper important. De forma específica, els problemes a estudiar són els següents: (i) Fotoionització de l’àtom d’heli i de l’àtom de liti mitjançant un làser intens. (ii) Estudi de la relació entre la formulació de X. Oriols amb la aproximació de Born–Oppenheimer. (iii) Estudi de les correlacions quàntiques en sistemes bi- i tripartits en l’espai de configuració de les partícules mitjançant la formulació de de Broglie–Bohm.

Sociedades cooperativas: mercantilidad y operaciones con terceros. Un comentario

En este trabajo se hace referencia a la posible consideración de las sociedades cooperativas como sociedades mercantiles, cumpliéndose determinadas circunstancias, y ello sin pérdida de sus características específicas en cuanto a la toma de decisiones, el reparto de beneficios y la búsqueda de la satisfacción de fines de interés general. Asimismo, se analizan las consecuencias de aumentar el porcentaje de operaciones realizadas con terceros no socios, respecto del total de operaciones realizadas por la sociedad cooperativa, y su incidencia en la cuantía de los fondos de la cooperativa y en la retribución del socio cooperativista. Se realiza en este punto una comparación con las sociedades capitalistas convencionales (S.A., S.L.). Finalmente, se propone una reforma legislativa al objeto de permitir aumentar el porcentaje de realización de operaciones cooperativizadas con terceros no socios, y ello sin pérdida de su tratamiento fiscal favorable.

Anàlisi i disseny d'un reflector per banda W

Les ones passives mil·limètriques (30 a 300GHz) tenen la peculiaritat de propagar-se en medis com la boira o la roba, a diferència del rang visible o l’infraroig. D’aquesta peculiaritat, surt l’interès de reproduir imatges per diverses aplicacions (seguretat, vigilància, etc...). És per aquest motiu que es treballa en el disseny d’un reflector per aquest tipus d’aplicació, treballant a una de les finestres de propagació d’aquest rang, la de la banda W. Es dissenyen i analitzen tres tipus de reflector: parabòlic simètric, offset i Cassegrain. D’aquests, s’estudien les seves figures de mèrit i directivitats buscant que aquestes siguin el més elevades possibles per obtenir una bona resolució, així com l’escaneig de l’escena de la qual es vol obtenir una imatge, veient aquí els efectes de les aberracions més comunes.

El retorno a las competencias para los titulados universitarios catalanes

In this paper the impact of different types of competences in the labor market for college graduates is investigated. We use two waves of a new data set of Catalan college graduates interviewed three years after graduation. We use wages equation to calculate the payoff to management, communication, specific and instrumental competences. By far, management competences are those which command a higher pay-off. This positive pay-off seems to be independent of individuals’ cognitive capacities. We show that most of the individual endowment in management competences is developed in the workplace. However, a strong background of theoretical knowledge (developed in the class room) helps a great deal to accumulate working related competences and, hence, has a large indirect pay-off.

Sobreeducación y Sobrecualificación en los Universitarios Catalanes. Una perspectiva de género

Partiendo de una muestra compuesta por más de 19.000 titulados universitarios encuestados en 2008 y 2011, 3 años y medio después de haber finalizado sus estudios, obtenemos que la incidencia de la sobreeducación femenina está por debajo de la masculina. Con la sobrecualificación los resultados son similares. Las estimaciones de las ecuaciones salariales indican que el desajuste educativo y competencial generan una importante reducción de los ingresos para ambos sexos. La penalización a la sobreeducación es mayor para las tituladas. En cambio, se observa que la pérdida de ingresos causada por la sobrecualificación en las competencias de gestión es mayor para los hombres. El efecto de la sobrecualificación en sus niveles más elevados llega a equilibrar el impacto más favorable de la sobreeducación masculina. Los resultados obtenidos no se pueden explicar a través de la segmentación del mercado laboral de los graduados, ni tampoco a partir de la preferencia femenina por condiciones laborales a las cuales otorgan atributos positivos. En cambio, no es posible rechazar la existencia de discriminación hacia las egresadas. Tampoco es posible descartar que las asimetrías en el impacto de los desajustes estén causadas por una concepción distinta del fenómeno de la sobreeducación por parte de hombres y mujeres.

Workers cooperation within the firm: an analysis using small and medium size firms

We investigate the determinants of teamwork and workers cooperation within the firm. Up to now the literature has almost exclusively focused on workers incentives as the main determinants for workers cooperation. We take a broader look at the firm's organizational design and analyze the impact that different aspects of it might have on cooperation. In particular, we consider the way in which the degree of decentralization of decisions and the use of complementary HRM practices (what we call the .rm.s vertical organizational design) can affect workers'collaboration with each other. We test the model's predictions on a unique dataset on Spanish small and medium size firms containing a rich set of variables that allows us to use sensible proxies for workers cooperation. We find that the decentralization of labor decisions (and to a less extent that of task planning) has a positive impact on workers cooperation. Likewise, cooperation is positively correlated to many of the HRM practices that seem to favor workers'interaction the most. We also confirm the previous finding that collaborative efforts respond positively to pay incentives, and particularly, to group or company incentives.

Wage effects from changes in local human capital in Britain

This paper examines the impact of local human capital on individuals’ wages through external effects. Employing wage regressions, it is found that changes in individuals’ wages are positively associated with changes in the shares of high-paid occupation workers in the British travel-to-work-areas for the late 1990s. I examine this positive association for different occupational groups (defined by pay) in order to disentangle between production function and consumer demand driven theoretical explanations. The wage effect is found to be stronger and significant for the bottom-paid occupational quintile compared to the middle-paid ones, and using also sectoral controls the paper argues to provide evidence for the existence of consumer demand effects.

Environmental Tax on Products and Services Based on Their Carbon Footprint: A Case Study of the Pulp and Paper Sector

The main aim of this work is to define an environmental tax on products and services based on their carbon footprint. We examine the relevance of conventional life cycle analysis (LCA) and environmentally extended input-output analysis (EIO) as methodological tools to identify emission intensities of products and services on which the tax is based. The short-term price effects of the tax and the policy implications of considering non-GHG are also analyzed. The results from the specific case study on pulp production show that the environmental tax rate based on the LCA approach (1,8%) is higher than both EIO approaches (0,8% for product and 1,4% for industry approach), but they are comparable. Even though LCA is more product specific and provides detailed analysis, EIO would be the more relevant approach to apply economy wide environmental tax. When the environmental tax considers non-GHG emissions instead of only CO2, sectors such as agriculture, mining of coal and extraction of peat, and food exhibit higher environmental tax and price effects. Therefore, it is worthwhile for policy makers to pay attention on the implication of considering only CO2 tax or GHG emissions tax in order for such a policy measure to be effective and meaningful.
