We present a macroeconomic agent-based model that combines several mechanisms operating at the same timescale, while remaining mathematically tractable. It comprises enterprises and workers who compete in a job market and a commodity goods market. The model is stock-flow consistent; a bank lends...

Whenever customers' choices (e.g. to buy or not a given good) depend on others choices (cases coined 'positive externalities' or 'bandwagon effect' in the economic literature), the demand may be multiply valued: for a same posted price, there is either a small number of buyers, or a large one --...

We consider a model of socially interacting individuals that make a binary choice in a context of positive additive endogenous externalities. It encompasses as particular cases several models from the sociology and economics literature. We extend previous results to the case of a general...

Nous testons en laboratoire trois instruments destinés à réguler l’exploitation d’une ressource commune par des agents hétérogènes : un système de taxes et de subventions, des quotas individuels transférables et non transférables. Nous proposons un modèle dans lequel l’objectif...

Organic farming covers just 3.5% of the utilised agricultural area (UAA) in France (2011 Agence Bio figures). Sales statistics show that a mere 2.3% of the French food market came from organic farming in 2008. The French government’s Environment Forum (“Grenelle de...

The behavioural game theory proposes a frame for modelling human behaviours in strategic interactions in a general, predictive and realistic way. Using the huge amount of experimental data accumulated during the last 25 years, and the recent results in neuroeconomics, this approach renews the...

We test in a laboratory experiment three regulations imposed on a common-pool resource game: an access fee and subsidy scheme, transferable quotas and non-transferable quotas. Theory predicts that they all reduce resource use from free access to the same target level without hurting users. We...

La prise en compte de l'intérêt du citoyen dans la décision publique passe par l'estimation des préférences individuelles. Dès lors qu'il n'existe pas demarché de référence, mesurer l'impact d'une décision publique sur le bien-être des individus pose un vrai problème méthodologique....

We know (e.g. Noussair et alii [2004]) that consumers devalue first-generation GM food. Here, using a framed field experiment method, we reveal consumer?s willingness to pay for various second-generation GM apples, defined as differentiated products containing an innovative attribute, desirable...
