The effect of flooding on mental health: lessons learned for building resilience
(American Geophysical Union, 2017) Foudi, Sébastien; Osés Eraso, Nuria; Galarraga, Ibon; Economía; Ekonomia
Risk management and climate adaptation literature focuses mainly on reducing the impacts of, exposure to, and vulnerability to extreme events such as floods and droughts. Posttraumatic stress disorder is one of the most important impacts related to these events, but also a relatively under-researched topic outside original psychopathological contexts. We conduct a survey to investigate the mental stress caused by floods. We focus on hydrological, individual, and collective drivers of posttraumatic stress. We assess stress with flood-specific health scores and the GHQ-12 General Health Questionnaire. Our findings show that the combination of water depth and flood velocity measured via a Hazard Class Index is an important stressor; and that mental health resilience can be significantly improved by providing the population with adequate information. More specifically, the paper shows that psychological distress can be reduced by (i) coordinating awareness of flood risks and flood protection and prevention behavior; (ii) developing the abil- ity to protect oneself from physical, material and intangible damage; (iii) designing simple insurance proce- dures and protocols for fast recovery; and (iv) learning from previous experiences.

Incentives to give up resource extraction and avoid the tragedy of the commons
(2013) Benito Ostolaza, Juan Miguel; Osés Eraso, Nuria; Economía; Ekonomia
This paper develops a general model of common resource extraction where we introduce payments for environmental services to encourage resource users to give up extraction. The goal is to reach a balance between resource use and conservation. As the essence of conservation is dynamic, we use a dynamic model to study the implementation of the compensation scheme. A stable heterogeneous equilibrium can be reached where both extractors and non-extractors live together. We analyze how the success of the compensation depends on factors such as the elasticity of demand and the biological characteristics of the resource.

Negative externalities in cropping decisions: private versus common land
(2013) Benito Ostolaza, Juan Miguel; Ezcurra Orayen, Roberto; Osés Eraso, Nuria; Economía; Ekonomia
This paper analyzes to what extent the definition of property rights affects cropping decisions when these decisions generate negative externalities. To that end, we implement an experimental study where agents make cropping decisions in two different treatments: private and common land. The results show that there are no statistically significant differences between the two treatments in the contribution to the negative externality, thus revealing that the definition of property rights does not affect cropping decision in this context. Furthermore, our findings indicate that the implication of the agents in activities generating negative externalities tends to increase over time, thus amplifying its adverse consequences.

Apropiación de comunales. Un estudio experimental
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2003) Osés Eraso, Nuria; Viladrich Grau, Montserrat; Economía; Ekonomia
El presente trabajo estudia la apropiación de recursos de propiedad común utilizando las técnicas de la economía experimental. Introducimos un diseño experimental lineal que permite estudiar el papel que la menor o mayor abundancia de recursos juega en las actitudes de apropiación de los usuarios del comunal. Observamos que la apropiación disminuye con la escasez.
