; ; ; Ambiguity acts as a veil that can help conceal and justify dishonest behavior. While an individual’s ability to disambiguate information in a task may help remove the veil of ambiguity and thus promote honesty, the relationship between ambiguity, ability, and dishonesty is currently unexplored. To investigate this, we employed an experimental design where participants attempted to resolve an ambiguous task and reported their performance. Results showed that ambiguity and dishonesty increase in unison. Importantly, the participants who resolved ambiguity acted less dishonestly (Study 1). In Studies 2a, 2b, and 3, we increased participants’ ability by briefly training them to disambiguate the information presented in the task. The results showed that participants acted less dishonestly when their ability levels were increased. Overall, the findings indicate that dishonesty can be reduced not only by making tasks less ambiguous but also by enhancing an individual’s ability to successfully resolve ambiguity. - PublicationAccès libreL'économie de l'environnement : un oxymore?L'économie et le système capitaliste sont souvent considérés comme étant à la racine de problèmes environnementaux. Cela peut induire une perception selon laquelle l'économie et la préservation de l'environnement sont en opposition. Dans ce texte, j'illustre en quoi une compréhension de l'économie est nécessaire pour contribuer à résoudre les problèmes environnementaux. Prenant les changements climatiques comme exemple, je mobilise deux types d'outils utilisés par les économistes. Premièrement, je développe un modèle sous la forme d’une allégorie. Je montre qu'un système capitaliste dans lequel il n'existe pas de droits de propriété explicites sur certaines ressources naturelles crée une situation de dilemme social : les actions individualistes vont à l’encontre de l’intérêt collectif. Deuxièmement, à l'aide d’outils empiriques, je discute des impacts économiques des changements climatiques et des interventions pour solutionner le dilemme social. Les résultats montrent qu'un investissement pour imiter les changements climatiques au niveau global coûte moins cher que l’inaction. Je considère ensuite trois types d’interventions en lien avec l'existence de droits de propriété implicites : (i) l'éducation et l'information, (ii) la régulation des marchés, et (iii) le soutien à l'innovation et à l'adoption de nouvelles technologies. Je conclus sur le fait que l'économie de l'environnement peut contribuer à développer des stratégies pour équilibrer les intérêts économiques et la préservation de l'environnement. L'innovation et la coopération au niveau global sont possibles, en témoigne la crise COVID.

- PublicationAccès libreImpacts of rainfall shocks on out-migration are moderated more by per capita income than by agricultural output in Türkiye(2023)
; ; ; Rural populations are particularly exposed to increasing weather variability, notably through agriculture. In this paper, we exploit longitudinal data for Turkish provinces from 2008 to 2018 together with precipitation records over more than 30 years to quantify how variability in a standardized precipitation index (SPI) affects out-migration as an adaptation mechanism. Doing so, we document the role of three potential causal channels: per capita income, agricultural output, and local conflicts. Our results show that negative SPI shocks (droughts) are associated with higher out-migration in rural provinces. A mediated-moderator approach further suggests that changes in per capita income account for more than one quarter of the direct effect of droughts on out-migration, whereas agricultural output is only relevant for provinces in the upper quartile of crop production. Finally, we find evidence that local conflict fatalities increase with drought and trigger out-migration, although this channel is distinct from the direct effect of SPI shocks on out-migration. - PublicationAccès libreReciprocity and gift exchange in markets for credence goods(2023)
; ; We study the role of reciprocity in markets where expert-sellers have more information about the severity of a problem faced by a consumer. We employ a standard experimental credence goods market to introduce the possibility for consumers to gift the expert-seller before the diagnostic, where the gift is either transferred unconditionally or conditionally on solving the problem. We find that both types of gifts increase the frequency of consumer-friendly actions relative to no gift, but only conditional gifts translate into efficiency gains when the consumer faces a high-severity problem. This suggests that partial alignment of incentives via conditional gifts may outweigh kindness motives when reciprocal actions are not directly observed. Using further treatments with surprise gift exchange, we show that withholding a gift that is expected by expert-sellers significantly reduces the likelihood of consumer-friendly behavior whereas sending a gift to expertsellers who do not expect one has no effect.
