El objetivo de CESS es promover el uso de metodologías experimentales, para ello es que se invita a investigadores y académicos que estén trabajando en el diseño de su experimento a que puedan presentar en las charlas que ofrece CESS.

Estas charlas son una instancia perfecta para que investigadores, académicos y estudiantes de post-grado puedan obtener feedback constructivo sobre el diseño e implementación de sus experimentos.

Para asistir o presentar en las charlas organizadas por el centro por favor escríbanos a cess@usach.cl.

Título: “Deterring Poaching from a Common Pool: Experimental Evidence from TURFs in Chile” (con Jim Murphy y John K. Stranlund)

Abstract: This work presents the results of an economic field experiment designed to study behavioral issues related to both the protection of a common-pool resource from poaching by outsiders, and the problem of managing a local common resource within a group under the presence of outsiders when enforcement is imperfect and costly. We have two specific objectives. First, to study the ability of group members to manage the resource in the presence of poaching. We examine the consequences of the inclusion of additional subjects, called “outsiders,” who do not have the right to harvest the resource or participate in management decisions, but can decide to encroach on the TURF and poach the resource. Second, to study different methods for the “insiders” to monitor the resource and impose sanctions. In all cases, monitoring is imperfect (i.e., there is a chance that poaching will not be detected). Enforcement treatments in our experiment include: i) relying on an external agency to provide enforcement; and ii) allowing insiders to share the responsibility of monitoring the resource at a personal cost. The experiments were conducted in the field with 210 members of local artisanal fishing organizations in central-southern Chile. The participants are members of organizations exploiting benthic resources under TURFs regulation.

Título: “Peer effects in After-school programs. Evidence from El Salvador”

Abstract: This paper studies the impact of After-School Clubs on students’ academic results and violence-related outcomes, using an experimental design. Participants are enrolled in schools located in highly violent communities in a developing country. The premise is that clubs improve children’s ability to handle conflicts, which also allows them to improve their protection factors and academic performance. Then, randomly assigning students in heterogeneous (non-tracking) or homogeneous (tracking) groups according to their predicted violence level, this paper measures peer effects on academic and non-cognitive outcomes. As results, I find positive effect of the program on grades and behavior. Also a reduction in their self- and external reports of students’ violence and delinquency actions. Finally, I find a reduction in their perception of exposition to risky environments outside school. These results are driven by the homogeneous group, but I find no impact differences due to the group composition. Finally, I find differences in terms of gender and the predicted initial level of violence. With these results, I will contribute to the design and implementation of public policies to prevent violence in children and adolescents involved in highly risky school environments.

Título: “Antecedent Social Factors of Moral Behaviour: Experimental Design”

Abstract: Social factors like hierarchies, patterns of class inequality, and mobility regimes that individuals experience can work as determinants of moral behaviour, producing different and conflicting ways in which ‘moral’ choices are made and justified. Disparities in moral behaviour are salient in mixed-motive social dilemmas; situations where individuals’ immediate self-interest is at odds with what is best for their relationships, community, or nation. Although an emerging body of research indicates that class position can be a source of moral variation, the study of these issues is scant in Chile, even though the country boasts high socio-economic inequality. This feature renders Chile as an adjudicative case to study the antecedent social factors of moral behaviour. This is the main focus of the research project “Antecedent Social Factors of Moral Behaviour: Expectations, Decisions, and Justificatory Principles”, funded by The National Fund for Scientific and Technological Research (FONDECYT, Grant Number 1161624). In this talk, we will present and discuss the experimental design of the first research line of this project, namely: belief elicitation of expected pro-social preferences using laboratory social dilemmas, where stereotypic representations of class-specific features relevant for the Chilean case –such as ethnicity, facial appearance, and socio-economic status– are manipulated.

Título: “Teoría de Juegos Experimental y Cooperación en la Vida Real”

Abstract: En esta charla se discute la forma en la que la teoría de juegos experimental puede ser utilizada para medir la adhesión a nivel individual a normas prosociales y su impacto en la estructura social y las capacidades colectivas de los grupos a los que pertenecen estos individuos en la vida real. En primer lugar, se presenta evidencia empírica entre la relación del comportamiento cooperativo en el laboratorio de pescadores artesanales en juegos de recursos comunes (common-pool resource games) y la sustentabilidad de estos recursos en las áreas de extracción exclusivas asignadas a las comunidades a las que pertenecen los sujetos experimentales. En segundo lugar, se discute una propuesta metodológica para medir en forma análoga al caso de las comunidades de pescadores artesanales, las capacidades para la cooperación en experimentos de bienes públicos, juegos repetidos diádicos y su potencial relación con aspectos positivos y negativos de la convivencia escolar.
