Most interventions against obesity use information to persuade people to change their behavior, with moderate results. Because eating involves automatic routines, new approaches have emerged appealing to non-reflective cognitive processes. Through a randomized controlled trial, we evaluated the impact of visual stimuli (positive and negative) on children's snack-choices at school. Results showed that the negative stimulus had no effect, while the positive stimulus increased the probability among girls of choosing a healthy snack. We also found that children with excess weight had a larger baseline probability of choosing the healthy snack than those without. We conclude that happy emojis, used to nudge non-reflective processes, can steer children towards healthy choices.

Cambio climático, riesgo de inundación y medidas de adaptación: retos en la valoración de daños y evaluación de medidas

Las inundaciones suponen un importante riesgo para el bienestar de las personas por el gran impacto que causan. Por ello, distintas instituciones han emprendido planes para la mejora de sistemas de alerta y prevención, mejoras que requieren información lo más precisa posible sobre los riesgos a los que se enfrenta la población y el entorno, los cuales se definen como la combinación de la probabilidad de darse un determinado suceso y el daño que potencialmente causaría. Este estudio tiene como fin avanzar en el establecimiento de metodologías que faciliten el análisis del riesgo, para lo cual se examinan varios de los estudios realizados en este contexto con el objetivo de extraer pautas metodológicas que puedan ser utilizadas en proyectos fluviales y áreas costeras.

Participation in and provision of public goods: does granularity matter?
(Springer, 2020) Arlegi Pérez, Ricardo; Benito Ostolaza, Juan Miguel; Osés Eraso, Nuria; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
We use public goods games to experimentally investigate the effect of granularity (i.e., the degree of divisibility of the space of feasible contribution options) on participation (whether individuals contribute or not to the public good) and public goods provision (total contribution to the public good). Our results show that granularity has a significant effect on participation, mainly when coarser granularity eliminates the possibility of small contributions. However, this change in participation does not lead to a significant change in the total provision of the public good. These results are aligned with other experimental field results obtained in the context of donations and fundraising.

Information, experience, and willingness to mitigate mental health consequences from flooding through collective defence
(American Geophysical Union, 2022) Foudi, Sébastien; Osés Eraso, Nuria; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
Demand for reducing mental health impacts from flooding through collective flood defence is elicited using a contingent valuation method with a sequential hypothetical scenario, which accounts for human resilience and experience. A two-step model fits the survey data: it combines a binary sample selection rule to distinguish protesters and participants with a Tobit model to accommodate true zero responses among participants. Results show that non-symptoms-specific information on mental health risk may bias the willingness to pay downward. Risk-averse individuals who have taken self-insurance protection measures are willing to pay for additional protection through collective defence. Feelings, such as worries and anxiety related to flooding, drive the demand, which supports the risk-as-feelings hypothesis for mental health protection from flooding. Inexperience rather than experience of flooding is found to increase demand, which indicates that individual mental resilience to flooding may increase after an event as posited by the inoculation hypothesis.

Do wealth levels affect the contribution to negative externalities?
(Elsevier, 2020) Benito Ostolaza, Juan Miguel; Ezcurra Orayen, Roberto; Osés Eraso, Nuria; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
This paper experimentally explores the link between poverty and decisions that lead environmental degradation. In the experiment, individuals with different wealth levels play a game that describes environmental degradation as a contribution to an activity that generates a negative externality. The experimental data show that wealth levels not related to the environment (exogenous poverty) play no significant role in environmental decisions. However, the variation in wealth as a consequence of the contribution to environmental degradation (endogenous poverty) affects the behavior of individuals, that enter a spiral of poverty and environmental degradation. These results suggest the existence of a poverty-environment trap.

Valoración de riesgos por inundaciones
(Ministerio de Hacienda: Servicio de Publicaciones, 2020) Osés Eraso, Nuria; Foudi, Sébastien; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
Este trabajo analiza cómo las curvas de probabilidad daño y el daño anual esperado, como indicadores del riesgo de inundación, se ven afectados por el cambio climático, las medidas de prevención estructurales o no estructurales y los efectos inesperados como el efecto dique. Subraya las interacciones entre medidas privadas no estructurales y públicas estructurales en la adaptación al cambio climático. Un ejemplo, con la apertura del canal de Deusto en Bilbao, ilustra cómo una medida estructural modifica el riesgo de inundación y permite discutir el papel de las medidas no estructurales en la adaptación.
