This paper investigates the impact of uncertainty and attitudes toward uncertainty on charitable donations through a theoretical model and an experimental approach. Specifically, we propose the neo-additive capacities model (Chateauneuf et al. 2007) and conduct a laboratory experiment to test its predictions. The experiment employs a modified dictator game in which donations are made to environmental NGOs, with the donations exposed to varying types of uncertainty: risk, low ambiguity, and high ambiguity. Using a Bayesian hierarchical model, we estimate ambiguity parameters and find that differences in donation behavior across types of uncertainty depend on individuals' pessimism. These results suggest that pessimistic individuals tend to donate less as uncertainty increases, whereas optimistic individuals donate more as uncertainty grows. We add evidence about the ambivalent effect of ambiguity based on heterogeneous ambiguity attitudes, demonstrating how heterogeneous ambiguity attitudes shape donation behavior. This paper highlights the nuanced relationship between uncertainty and prosocial behavior, offering new insights into the role of ambiguity in decision-making contexts.

In collaboration with the environmental association Sustainable Ties and the Repair Cafés network, the project aims to explore practices aimed at extending the life of products through repair. We are investigating the determinants and levers that encourage repair behaviors, specifically for electrical and electronic equipment. The project includes laboratory and field experiments targeting various populations, as well as a discrete choice experiment to assess the viability of repair contracts.
One-risk
This project explores the "One Health" approach, which highlights the interconnection between human, animal, and environmental health. The project focuses on understanding the behavioral dynamics associated with public health policies, especially in the context of zoonotic diseases, which have spread due to globalization and climate change. Using concepts from behavioral economics such as collective action, risk-taking, and uncertainty, we will examine the effectiveness of public policy tools (e.g., subsidies, regulations, awareness campaigns) in influencing risk perceptions and aligning individual actions with public health objectives.
