Researchers argue that third parties help sustain human cooperation, yet how they contribute remains unclear, especially in small-scale, politically decentralized societies. Studying justice among Mentawai horticulturalists in Indonesia, we examined evidence for punishment and mediation by third...

Considered as a cornerstone of development, financial inclusion has become a universal goal, in particular for developing countries that happen to be characterized by a high degree of labor informality. Our aim in this paper is twofold. First, we study how labor informality affects financial...

This paper proposes a solution to the problem of the self-selection of peers in the linear-in-means model. We do not require to specify a model for how the selection of peers comes about. Rather, we exploit two restrictions that are inherent in many such specifications to construct conditional...

We consider the problem of sharing the cost of a fixed tree-network among users with differentiated willingness to pay for the good supplied through the network. We find that the associated value-sharing problem is convex, hence, the core is large and we axiomatize a new, computationally simple...

We present a set of necessary and sufficient conditions for a class of optimal con- trol problems with pure state constraints for which the objective function is lin- ear in the state variable but the objective function is only required to be upper semicontinuous in the control variable. We apply...

The social value of decreasing health risks can be evaluated using benefit-cost analysis (BCA), cost-effectiveness analysis (CEA), or a social-welfare function (SWF). These frameworks can produce different social preference rankings of interventions depending on how their health effects and costs...

This article considers a class of experimentation games with Lévy bandits encompassing those of Bolton and Harris (1999, Econometrica, 67, 349–374) and Keller, Rady, and Cripps (2005, Econometrica, 73, 39–68). Its main result is that efficient (perfect Bayesian) equilibria exist whenever players’...

We provide a lower bound showing that the O(1/k) convergence rate of the NoLips method (a.k.a. Bregman Gradient or Mirror Descent) is optimal for the class of problems satisfying the relative smoothness assumption. This assumption appeared in the recent developments around the Bregman Gradient...

The study aims at valuing mangrove ecosystem services in Xuan Thuy National Park, Red River Delta, Vietnam. A discrete choice experiment was employed to elicit household willingness to pay (WTP) for a community project to protect mangroves against climate change. A conditional logit model and a...

In 2019, obesity affected 17% of French adults. In this article, we use a unique data set that combines individual-level health and consumption data with living environment data (food, sports and health amenities). We develop a spatial econometric framework to address French health disparities in...
