Musculoskeletal pain is the most debilitating human health condition. Neurophysiological pain mechanisms are highly conserved and promote somatic maintenance and learning to avoid future harm. However, some chronic pain might be more common owing to mismatches between modern lifestyles and traits...

We introduce and analyse the almost sure convergence of a new stochastic algorithm for the global minimization of Morse functions on compact Riemannian manifolds. This di˙usion process is called fraudulent because it requires the knowledge of minimal value of the function. Its investigation is...

We study insurance and portfolio decisions, two opposite risk retention tradeoffs. Using household level data, we identify the first joint determinants (e.g. subjective expecta-tions, risk attitude) and frictions (e.g. liquidity constraints, financial literacy) in the literature. We also find key...

We develop a schedule delay model using advanced econometrics techniques, while computing the social cost of passenger delays, in order to propose an alternative to the method of defining such cost that is actually found in the literature. This study has been made possible by obtaining private...

We introduce a non zero-sum game between a government and a legislative body to study the optimal level of debt. We succeed in characterising Nash equilibria in the class of Skorokhodreflection policies which implies that the legislator imposes a debt ceiling. In addition, we highlight the...

The prisoners’ dilemma, the snowdrift game, and the stag hunt are simple two-player games that are often considered as prototypical examples of cooperative dilemmas across disciplines. However, surprisingly little consensus exists about the precise mathematical meaning of the words “cooperation”...

Cooperation usually becomes harder to sustain as groups become larger because incentives to shirk increase with the number of potential contributors to collective action. But is this always the case?Here we study a binary-action cooperative dilemma where a public good is provided as long as not...

We develop a dynamic computable general equilibrium (CGE) model to assess the macroeconomic impacts of water scarcity and water (in)security in South Africa. The CGE model which includes a detailed representation of water resources (surface water, groundwater, wastewater, and seawater) has been...

We analyze a Pareto optimal income tax problem à la Mirrlees (1971) in which households consume three types of goods: energy goods, energy efficient investments and non-energy goods. The two main ingredients of our normative analysis are: i) an indirect relationship between energy and the...

This article explains how leaders can use foreign policy issues to shape their personal images. It argues, in particular, that presidents and presidential candidates can use hawkish foreign policies to craft valuable impressions of leadership strength. This dynamic can give leaders incentives to...
