The three wives problem and Shapley value
2015
We examine the Talmudic three wives problem, which is a generalization of the Talmudic contested garment problem solved by Aumann and Maschler (1985) using coalitional procedure. This problem has many practical applications. In an attempt to unify all Talmudic methods, Guiasu (2010, 2011) asserts that it can be explained in terms of “run-to-the-bank”, that is, of Shapley value in a “cumulative game”. It can be challenged because the coalitional procedure yields the same result as the nucleolus, which corresponds to a “dual game”. As Guiasu's solution is paradoxical (it has all the appearances of truth), my contribution consists in explaining the concepts, particularly truncation, that play …
Perception du risque dépendance et demande d'assurance : une analyse à partir de l'enquête PATER
2013
Dans la littérature économique, de nombreux travaux tentent d'expliquer pourquoi les individus s’assurent aussi peu contre la dépendance. Du côté de l’offre, différents freins possibles au développement du marché de l’assurance dépendance ont d’ores et déjà été pointés du doigt par la littérature. Les estimations récentes montrent néanmoins que les limites imputables à l’offre ne suffisent pas à expliquer le faible développement du marché : même si les assurances étaient moins coûteuses et les couvertures proposées plus larges, la majorité des individus ne souscrirait toujours pas d’assurance. Il est donc nécessaire d’aller trouver des explications du côté de la demande d’assurance dépendan…
The paradox of endogenous poverty line in the poverty indices
2007
february 23-25, 2007; When measuring poverty, the poverty line is considered to be relatively determined as a percentage of the median income or as a percentage of the average income so as to allow international comparisons. The poverty line relative to the median income may be described as endogenous in contrast with the poverty line relative to the average income which may be described as exogenous because it is independent of the normalized distribution of incomes. As the existing literature is focused on the properties of the indices but not on the respective interest of the endogenous and exogenous poverty lines, this paper compares the two definitions of the relative poverty. The Rela…
Is Democracy Exportable?
2017
Among many aspects to the question of whether democracy is exportable, this contribution focuses on the role of the people, understood not as a unitary actor but as a heterogeneous set: the citizens. The people matter, in a different way, both in the countries to which democracy might be exported and in the democratic countries in which the question is about promoting democracy elsewhere. The mechanisms or characteristics involved in the discussion include yardstick competition, differences among citizens in the intensity of their preferences, differences among autocracies regarding intrusion into private life, citizens’ assessments of future regime change, and responsiveness of elected inc…
