Do experimental subjects favor their friends?

Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just part of a long run interaction. Unfortunately, it is not easy to reach those conditions and experimenters try to mitigate any effects from those out-of-the-lab relationships by, for instance, randomly matching subjects. However, even if this type of procedure is used, there is a positive probability that a subject may face a friend or an acquaintance. We find evidence that social proximity between subjects is irrelevant to experiment results in dictator games. Thus, although ideal conditions are not met, relations between subjects do not contaminate the results of experiments.

Turnout Intention and Social Networks

How can networking affect the turnout in an election? We present a simple model to explain turnout as a result of a dynamic process of formation of the intention to vote within Erdös-Renyi random networks. Citizens have fixed preferences for one of two parties and are embedded in a given social network. They decide whether or not to vote on the basis of the attitude of their immediate contacts. They may simply follow the behavior of the majority (followers) or make an adaptive local calculus of voting (Downsian behavior). So they either have the intention of voting when the majority of their neighbors are willing to vote too, or they vote when they perceive in their social neighborhood that elections are "close". We study the long run average turnout, interpreted as the actual turnout observed in an election. Depending on the combination of values of the two key parameters, the average connectivity and the probability of behaving as a follower or in a Downsian fashion, the system exhibits monostability (zero turnout), bistability (zero turnout and either moderate or high turnout) or tristability (zero, moderate and high turnout). This means, in particular, that for a wide range of values of both parameters, we obtain realistic turnout rates, i.e. between 50% and 90%.

Prosocial norms and degree heterogeneity in social networks

We provide empirical evidence to support the claims that social diversity promotes prosocial behavior. We elicit a real-life social network and its members’ adherence to a social norm, namely inequity aversion. The data reveal a positive relationship between subjects’ prosociality and several measures of centrality. This result is in line with the theoretical literature that relates the evolution of social norms to the structure of social interactions and argues that central individuals are crucial for the emergence of prosocial behavior.

Multifuncionalidad rural y percepción social en el País Vasco: un reconocimiento pendiente

[ES] Los planes de desarrollo rural del País Vasco se apoyan en gran medida en sus potencialidades naturales, paisajísticas y productivas dirigidas a un urbano que vive en la proximidad. La apreciación de la calidad del entorno rural por parte del ciudadano, por tanto, es fundamental para el progreso de las zonas rurales y supone implícitamente el reconocimiento de la multifuncionalidad de este medio. El urbano, sin embargo, aunque aprecia el entorno natural de los espacios rurales desconoce la función del agricultor en la conservación de este medio siendo la productiva la única aportación que liga a su actividad. El desarrollo rural ha de pasar por el reconocimiento social y para ello es necesario informar y educar al ciudadano.

Envejecimiento, caserío y atención social: la familia asume el cuidado del mayor

[ES] La desestructuración familiar que en España ha supuesto un éxodo rural intensivo queda en evidencia varias décadas después, una vez que la población que decidió continuar residiendo en el medio rural ha envejecido. El anciano que habita en el medio rural carece a menudo del apoyo familiar necesario para hacer frente a las barreras físicas y sociales que la edad y el aislamiento le imponen mientras los servicios públicos no se adecúan a los caracteres propios de este medio. El habitante del caserío vasco, dada la proximidad del medio urbano, ha sufrido en menor medida las consecuencias del éxodo rural, manteniéndose más íntegra la red de apoyo familiar o, en todo caso, viéndose completada con la presencia del que acudió al medio urbano. Como consecuencia, es la familia la que asume el cuidado del mayor, cumpliendo éste su deseo de residir en casa hasta el final de su vida.
