The Impact of Regulation on Pricing Behavior in the Spanish Electricity Market

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.

Strategic Behavior and Collusion: An Application to the Spanish Electricity Market

The paper has two major contributions to the theory of repeated games. First, we build a supergame oligopoly model where firms compete in supply functions, we show how collusion sustainability is affected by the presence of a convex cost function, the magnitude of both the slope of demand market, and the number of rivals. Then, we compare the results with those of the traditional Cournot reversion under the same structural characteristics. We find how depending on the number of firms and the slope of the linear demand, collusion sustainability is easier under supply function than under Cournot competition. The conclusions of the models are simulated with data from the Spanish wholesale electricity market to predict lower bounds of the discount factors.

El proceso contra Jato Tello (Vitoria 1485): ¿Error judicial o empleo de la justicia penal en la política antijudía?

[ES]El objeto de este artículo es saber hasta qué punto pudo emplearse la justicia penal como un instrumento más de la política de carácter antijudío desarrollada por las autoridades cristianas de la España medieval a finales del siglo XV, concretamente en los momentos previos a la expulsión. Para indagar sobre esta cuestión se tendrá presente el proceso penal por blasfemia al que fue sometido el judío de Vitoria (Álava) Jato Tello.

Coalitional games with veto players: Myopic and farsighted behavior

This paper studies an allocation procedure for coalitional games with veto players. The procedure is similar to the one presented by Dagan et al. (1997) for bankruptcy problems. According to it, a player, the proposer, makes a proposal that the remaining players must accept or reject, and con ict is solved bilaterally between the rejector and the proposer. We allow the proposer to make sequential proposals over several periods. If responders are myopic maximizers (i.e. consider each period in isolation), the only equilibrium outcome is the serial rule of Arin and Feltkamp (2012) regardless of the order of moves. If all players are farsighted, the serial rule still arises as the unique subgame perfect equilibrium outcome if the order of moves is such that stronger players respond to the proposal after weaker ones.

Perfiles lingüísticos en la nueva oficina judicial: planificación lingüística en la administración de la Administración de Justicia

[ES]La adaptación de la Administración de Justicia al estatus de doble oficialidad lingüística exige la adopción de importantes medidas estructurales y organizativas que, hasta la fecha, no han resultado suficientemente efectivas. Este trabajo profundiza en los retos que en materia de lenguas se plantean a la Administración de Justicia, sobre la base del hilo conductor del sistema de planificación lingüística diseñado por la CAPV y su análisis desde la perspectiva de la jurisprudencia más reciente.

Modeling habits as self-sustaining patterns of sensorimotor behavior

In the recent history of psychology and cognitive neuroscience, the notion of habit has been reduced to a stimulus-triggered response probability correlation. In this paper we use a computational model to present an alternative theoretical view (with some philosophical implications), where habits are seen as self-maintaining patterns of behavior that share properties in common with self-maintaining biological processes, and that inhabit a complex ecological context, including the presence and influence of other habits. Far from mechanical automatisms, this organismic and self-organizing concept of habit can overcome the dominating atomistic and statistical conceptions, and the high temporal resolution effects of situatedness, embodiment and sensorimotor loops emerge as playing a more central, subtle and complex role in the organization of behavior. The model is based on a novel "iterant deformable sensorimotor medium (IDSM)," designed such that trajectories taken through sensorimotor-space increase the likelihood that in the future, similar trajectories will be taken. We couple the IDSM to sensors and motors of a simulated robot, and show that under certain conditions, the IDSM conditions, the IDSM forms self-maintaining patterns of activity that operate across the IDSM, the robot's body, and the environment. We present various environments and the resulting habits that form in them. The model acts as an abstraction of habits at a much needed sensorimotor "meso-scale" between microscopic neuron-based models and macroscopic descriptions of behavior. Finally, we discuss how this model and extensions of it can help us understand aspects of behavioral self-organization, historicity and autonomy that remain out of the scope of contemporary representationalist frameworks.

Análisis de las principales novedades del Reglamento (UE) 1215/2012 en la conquista de la libre circulación de las resoluciones en el espacio judicial europeo

El objetivo principal de este trabajo fin de grado es resaltar las novedades que ha incorporado el Reglamento 1215/2012 en el objetivo de un avance en la consecución de un verdadero espacio judicial europeo con el objeto de potenciar la libre circulación de las resoluciones judiciales en materia civil y mercantil en el ámbito de la Unión Europea. Los dos grandes objetivos de la reforma, la eliminación del exequátur y la extensión de las reglas unificadas de competencia con el propósito de suprimir la remisión a las reglas nacionales cuando el demandado no está domiciliado en un estado miembro, son objeto de estudio y crítica en este trabajo.

La técnica del interrogatorio judicial

[ES]Al escuchar la palabra interrogatorio, lo que normalmente sucede es que las personas asocien dicho término con el interrogatorio realizado por parte de la policía, debido a la gran cantidad de películas basadas en este tipo de interrogatorio. Lo que se ha pretendido a través de este trabajo es el estudio y análisis de las características y funciones que generalmente invaden el interrogatorio judicial, así como el examen de las distintas técnicas posibles a llevar a cabo para la consecución de su fin: la verdad sobre los hechos probados. Además, se ha querido subrayar la importancia e influencia que tiene la ciencia de la psicología en este campo, estableciendo y exponiendo diferentes claves psicológicas para realizar de una mejor manera el trabajo del abogado en el acto del interrogatorio judicial, ya que, aun siendo imprescindible el conocimiento de la ciencia del Derecho, ha de tenerse muy en cuenta y de hecho, no olvidarse de la ciencia de la Psicología.

A behavior model for blood donors and marketing strategies to retain and attract them

Objective: analyze and propose a theoretical model that describes blood donor decisions to help staff working in blood banks (nurses and others) in their efforts to capture and retain donors. Methods: analysis of several studies on the motivations to give blood in Spain over the last six years, as well as past literature on the topic, the authors' experiences in the last 25 years in over 15 Non Governmental Organizations with different levels of responsibilities, their experiences as blood donors and the informal interviews developed during those 25 years. Results: a model is proposed with different internal and external factors that influence blood donation, as well as the different stages of the decision-making process. Conclusion: the knowledge of the donation process permits the development of marketing strategies that help to increase donors and donations.

Studying the influence of substitutional elements on mechanical behavior of Alloy 718

In nickel-based superalloys, substitutional solute species have a strong impact on in service mechanical properties as well as on oxidation and corrosion resistances. In alloy 718, recent studies carried out by tensile tests highlighted the fact that refractory solute species are able to interact strongly with mobile dislocations during plastic deformation, generating dynamic strain ageing, and, in wide ranges of tests temperatures and strain rates, Portevin-Le Chatelier effect. The precise nature of the substitutional element responsible for such a dynamic interaction is still subject to debate. We addressed this question by means of mechanical spectroscopy studies of alloy 718 and various related alloys corresponding to monitored changes in the chemical composition. Only a single internal friction relaxation peak has been observed for all the studied alloys. By analyzing the damping behavior of these alloys at different imposed solicitation frequencies by sweeping a large temperatures range, the activation energies of the relaxation process and the type of mechanism involved have been determined. The process is a "Zener relaxation" in the alloys, i.e. a substitutional atoms dipole reorientation under applied stress. The results tend to prove that Niobium is not involved in the relaxation process whereas Molybdenum content seems to play an important role in the relaxation intensity.

Prosocial behavior and gender

This study revisits different experimental data sets that explore social behavior in economic games and uncovers that many treatment effects may be gender-specific. In general, men and women do not differ in "neutral" baselines. However, we find that social framing tends to reinforce prosocial behavior in women but not men, whereas encouraging reflection decreases the prosociality of males but not females. The treatment effects are sometimes statistically different across genders and sometimes not but never go in the opposite direction. These findings suggest that (i) the social behavior of both sexes is malleable but each gender responds to different aspects of the social context; and (ii) gender differences observed in some studies might be the result of particular features of the experimental design. Our results contribute to the literature on prosocial behavior and may improve our understanding of the origins of human prosociality. We discuss the possible link between the observed differential treatment effects across genders and the differing male and female brain network connectivity, documented in recent neural studies.
