Axiomatic models of decision under ambiguity with a non-unique prior allow for the existence of Crisp Fair Gambles: acts whose expected utility is nul whichever of the priors is used. But, in these models, the DM has to be indifferent to the addition of such acts. Their existence is then at odds...

We analyze the interplay between longevity, pollution and growth. We develop an OLG model where longevity, pollution and growth are endogenous. The authorities may provide two types of public services, public health and environmental maintenance, that participate to increase agents' life...

A growing literature on substitution between social programs provides consistent evidence that changes in the generosity of one program can lead to changes in enrollment on other programs. However, this evidence has been ignored in welfare analyses of social insurance programs. I demonstrate...

In many domains risky health behavior is still only poorly understood. Analysis is often plagued by incomplete data and a general lack of information. In this study; we try to understand the determinants of helmet use among motorcyclists in Delhi; a context in which road safety is very low. We...

The experience of the 2007-09 financial crisis has showed that the bank capital regulation in place was inadequate to deal with "manufacturing" tail risk in the financial sector. This paper proposes an incentive-based design of bank capital regulation aimed at efficiently dealing with tail risk...

We conduct a case study of the linkages of task organization, human capital accumulation and wages in Morocco, using matched worker-firm data for Electrical-mechanical and Textile-clothing industries. In order to integrate task organization into the interacting processes of workers' training and...

Nous montrons que l'approche par les capabilités offre de sérieuses pistes pour donner tout son sens à la justice environnementale abordée sous l'angle de la justice comparative. L'approche des capabilités permet de prendre en compte les trois enjeux que soulève la justice environnementale...

We introduce public debt in a Ramsey model with heterogenous agents and a public spending externality affecting utility which is financed by income tax and public debt. We show that public debt considered as a fixed portion of GDP can have a stabilizing or destabilizing effect depending on some...

This paper examines the relationship between environmental policy and growth when green preferences are endogenously determined by education and pollution. The government can implement a tax on pollution and recycle the revenue in public pollution abatement and/or education subsidy (influencing...

The value of land in the balance sheet of French firms correlates positively with their hiring and investment flows. To explore the relationship between these variables, we develop a macroeconomic model with firms that are subject to both credit and labor market frictions. The value of...
