La arqueología comercial en España: ¿un sistema sectorial de innovación?

[ES] La publicación de la Ley de Patrimonio Histórico Español en 1985 y el desarrollo de la construcción, especialmente de grandes infraestructuras, en la primera década del siglo XXI han sido los factores desencadenantes de la arqueología comercial en España.

Protocolo de prevención de partidos de riesgo: una experiencia aplicada para la prevención de la violencia en el fútbol base

[EN] This study presents an applied experience which takes part of a program on prevention of the violence in soccer in school age. The aim was the acquisition of the commitment of the trainers involved in matches considered as non sportive, in the fulfillment of sportive behavior guidelines. To achieve this aim, a meeting was carried out by the trainers of the equipments that led violent incidents in the first round of the league, with the presidents of these equipments, with representatives of the local football Federation and with representatives of the Committee of referees. From this meeting it was intended: 1) to reduce the probability of aggressive and violent incidents; 2) to promote a relation of cooperation between the entities of the teams that led non sportive incidents, and the referee group; and 3) Make the sports context be a protector to prevent non sportive behaviors. The results of this study reflect that the participation had a positive effect in the improvement of the sportsmanship in the return football matches of the league.

Las políticas tecnológicas y de innovación en la Comunidad Autónoma de Euskadi: El caso de los Clusters

[ES] En el presente trabajo se ha tratado de analizar la evolución de las políticas tecnológicas y de innovación en la Comunidad Autónoma de Euskadi (CAE), en las últimas tres décadas, prestando especial atención a la política de clusters. Es evidente el avance tecnológico e innovador experimentado por Euskadi en este período, basado en la estrecha cooperación desarrollada entre las universidades, las instituciones públicas y las empresas privadas. En este marco, la CAE fue pionera en el diseño y puesta en marcha de una política de clusters a principios de los años noventa. Tras más de dos décadas de funcionamiento de dicha política, ésta parece haberse consolidado existiendo en la actualidad 13 asociaciones cluster en Euskadi.

The Comovement between Monetary and Fiscal Policy Instruments during the Post-War Period in the U.S.

This paper empirically studies the dynamic relationship between monetary and fiscal policies by analyzing the comovements between the Fed funds rate and the primary deficit/output ratio. Simple economic thinking establishes that a negative correlation between Fed rate and deficit arises whenever the two policy authorities share a common stabilization objective. However, when budget balancing concerns lead to a drastic deficit reduction the Fed may reduce the Fed rate in order to smooth the impact of fiscal policy, which results in a positive correlation between these two policy instruments. The empirical results show (i) a significant negative comovement between Fed rate and deficit and (ii) that deficit and output gap Granger-cause the Fed funds rate during the post-Volcker era, but the opposite is not true.

Emergence of Cooperation in Heterogeneous Population: A Discrete-Time Replicator Dynamics Analysis

The emergence of cooperation is analyzed in heterogeneous populations where individuals can be classified in two groups according to their phenotypic appearance. Phenotype recognition is assumed for all individuals: individuals are able to identify the type of every other individual, but fail to recognize their own type, and thus behave under partial information conditions. The interactions between individuals are described by 2 × 2 symmetric games where individuals can either cooperate or defect. The evolution of such populations is studied in the framework of evolutionary game by means of the replicator dynamics. Overlapping generations are considered, so the replicator equations are formulated in discrete-time form. The well-posedness conditions of the system are derived. Depending on the parameters of the game, a restriction may exist for the generation length. The stability analysis of the dynamical system is carried out and a detailed description of the behavior of trajectories starting from the interior of the state-space is given. We find that, provided the conditions of well-posedness are verified, the linear stability of monomorphic states in the discrete-time replicator coincides with the one of the continuous case. Specific from the discrete-time case, a relaxed restriction for the generation length is derived, for which larger time-steps can be used without compromising the well-posedness of the replicator system.
