Au-delà du techno-solutionnisme
À l’heure où l’enjeu climatique devient plus que central, de nombreuses controverses émergent sur le rôle de l’innovation dans la transition écologique. Cet entretien permet de nuancer le débat sur la place de l’innovation dans cette transition. Loin de voir la sobriété et l’innovation comme antagonistes, les changements de comportements seraient des formes d’innovations sociétales à encourager

Investment Strategies and Corporate Behaviour with Socially Responsible Investors
Socially responsible investors constitute an important force in today's global financial markets. This paper examines conditions under which socially responsible investors induce companies to behave responsibly. We develop an asset pricing model in which some shareholders are active owners, that is, they engage companies by voting on strategic decisions. Differences of objective among shareholders arise because socially responsible investors valu…
The Welfare Cost of Vaccine Misallocation, Delays and Nationalism
I calibrate an eco-epidemiological age-structured Susceptible-Infected-Recovered (SIR) model of the B.1.1.7 covid variant on the eve of the vaccination campaign in France, under a stop-and-go lockdown policy. Three-quarters of the welfare benefit of the vaccine can be achieved with a speed of 100,000 full vaccination per day. A 1-week delay in the vaccination campaign raises the death toll by approximately 2500, and it reduces wealth by 8 billion…

Les approches économiques de la précaution
Le principe de précaution est très populaire aujourd’hui. Mais a-t-il un fondement économique ? Nous présentons deux théories économiques de la précaution. La première se base sur le cadre classique d’espérance d’utilité avec révision bayésienne des croyances. La seconde se fonde sur l’aversion à l’ambiguïté. Nous discutons l’intérêt, mais aussi les limites de ces deux approches.
The Effect of Ambiguity Aversion on Insurance and Self‐protection
The research leading to these results has received funding from the European Research Council under the European Community’s Seventh Framework programme (FP7/2007-2013) Grant Agreement no. 230589 and from the Chair “Risk markets and value creation” financed by SCOR at IDEI

Régulation des risques, principe de précaution et OGM »
La plupart des progres technologiques apportent des promesses de benefices et s’accompagnent de spectres de dangers. Ces dangers sont-ils acceptables au regard des benefices anticipes ? A l’image de ce qu’il en est pour les OGM, les perceptions de ces benefices et de ces dangers varient sensiblement au sein d’une meme population, ce qui conduit aux debats publics que nous connaissons a leur sujet en France. De plus, le sentiment prevaut que les d…
Les déterminants socio-économiques des comportements face aux risques
Un des faits marquants de 1'evolution recente de la Science est la chute inexorable des frontieres classiques entre les disciplines traditionnelles. Les idees ont tendance a ignorer ces fractures issues du passe. Elles nourrissent de nouveaux debats et ouvrent de nouveaux champs d'investigation. Les conferences pluridisciplinaires font flores. Les sections du CNRS recrutent dans les interfaces. Cette evolution est particulierement frappante aux m…
Aggregation of Heterogeneous Time Preferences
We examine an economy whose consumers have different discount factors for utility, possibly not exponential. We characterize the properties of efficient allocations of resources and of the shadow prices that would decentralize such allocations. We show in particular that the representative agent has a decreasing discount rate when, as is usually posited, all of a group's members have a constant discount rate and decreasing absolute risk aversion …
