Brasil ha implementado políticas públicas ofensivas para el desarrollo de los sistemas alimentarios de proximidad, desde el año 2003, y las redes de comercio justo, desde el año 2010. Estos dos temas fueron objeto de definiciones jurídicas precisas que enmarcan el rol de los actores : autoridades locales, asociaciones, empresas. Estas definiciones ...
We show that hosting the Olympic Games in 2012 had a positive impact on the life satisfaction and happiness of Londoners during the Games, compared to residents of Paris and Berlin. Notwithstanding issues of causal inference, the magnitude of the effects is equivalent to moving from the bottom to the fourth income decile. But they do not last very ...
Have malaria control efforts contributed to the reduction in infant mortality in Sub-Saharan Africa over the past 15 years? Using large household surveys collected in 19 countries between 2000 and 2015, we estimate the correlation between the distribution of bednets and the progress in child survival. We find that the large increase in bednets owne...
This paper reports results from a linear sanction cost variant of the power-to-take game, with implications for tax policies. We compare a pay-as-you-earn (PAYE) system with an ex-post taxation system in which payroll taxes are collected at the end of the fiscal year. Dissatisfaction with taxation, as proxied by the sanction in the power-to-take ga...

We consider restricted games on weighted graphs associated with minimum partitions. We replace in the classical definition of Myerson restricted game the connected components of any subgraph by the sub-components corresponding to a minimum partition. This minimum partition 𝒫min is i nduced by the deletion of the minimum weight edges. We provide fiv...
This article explores the link between productive relational contracts and corruption. Responsibility for a contract is delegated to a supervisorwho cares about both production and kickbacks paid by the agent, neither of which are explicitly contractible. We characterize the optimalsupervisor-agent relational contract and show that the relationship...
Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from \per-period utility". I prove rigorously that time consistency holds if and...
We propose a general model of oligopoly with firms relying on a two factor production function. In a first stage, firms choose a certain fixed factor level (capacity). In the second stage, firms compete on price, and adjust the variable factor to satisfy all the demand. When the factors are substitutable, the capacity constraint is " soft " , imply...
This paper examines intergenerational wealth mobility between fathers and children in France between 1848 and 1960. Considering wealth mobility in the long run requires taking into account not only positional mobility (that is, how families move within a given distribution of wealth), but also structural mobility induced by changes in the distribut...
Ce chapitre d'un ouvrage à paraître en l'honneur de Jean Gadrey montre son apport à la définition des services marchands et au périmètre de la Commission des comptes des services dans un premier temps. Dans un second temps ce papier s'attache à la définition de l'utilité sociale des organisations de l'économie sociale et solidaire pour laquelle Jea...
