We present a model of voluntary contributions for a local public good, with individuals in a fixed network. We consider the introduction of an informational nudge, and model individuals' reaction to the nudge using a moral cost function. Regardless of the regulator's level of information, an...

In this paper, we examine the cyclical dynamics of a Real Business Cycle model with ambiguity averse consumers and investment irreversibility using the smooth ambiguity model of Klibanoff et al. (2005, 2009). Ambiguity of belief about the productivity process arises as agents do not know the...

Understanding how knowledge is created and propagates within groups is crucial to explain how human populations have evolved through time. Anthropologists have relied on different theoretical models to address this question. In this work, we introduce a mathematically oriented model that shares...

Comme le montre le mouvement des gilets jaunes, beaucoup de concitoyens pensent que le changement climatique est grave, mais ne sont pas prêts à contribuer à l'effort collectif pour le prévenir. Les entreprises et le monde de la finance peuvent-ils se substituer à ce somnambulisme des citoyens et...

I calibrate a Multiple‐Risk Susceptible–Infected–Recovered model on the covid pandemic to analyze the impact of the age‐specific confinement and polymerase chain reaction (PCR) testing policies on incomes and mortality. Two polar strategies emerge as potentially optimal. The suppression policy...

We prove the existence of competitive equilibrium in the canonical optimal growth model with elastic labor supply under general conditions. In this model, strong conditions to rule out corner solutions are often not well justied. We show using a separation argument that there exist Lagrange...

Governments worldwide are increasingly concerned about the booming use of CBD (cannabidiol) products. However, we know little about the impact of their liberalization. We study a unique case of unintended liberalization of a CBD-based product (light cannabis) that occurred in Italy in 2017. Using...

What modes of moral reasoning do judges employ? We construct a linear SVM classifier for moral reasoning mode trained on applied ethics articles written by consequentialists and deontologists. The model can classify a paragraph of text in held out data with over 90 percent accuracy. We then apply...
