This survey deals with the economic academic literature on diagnostic tests, with a focus first on the determinants of the use of these tests by healthcare providers, and then on the incentives to develop new diagnostic tests. It is structured in four parts. The first part provides general results...

The Euler discretisation of Langevin diffusion, also known as Unadjusted Langevin Algorithm, is commonly used in machine learning for sampling from a given distribution µ ∝ e−U . In this paper we investigate a potential U : Rd −→ R which is a weakly convex function and has Lipschitz gradient. We...

Fueled by the ever-increasing need for statistics that guarantee the privacy of their training sets, this article studies the centrally-private estimation of Sobolev-smooth densities of probability over the hypercube in dimension d. The contributions of this article are two-fold : firstly, it...

While it is commonly assumed that farmers have higher, and foragers lower, fertility compared to populations practicing other forms of subsistence, robust supportive evidence is lacking. We tested whether subsistence activities—incorporating market integration—are associated with fertility in 10,...

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...

Direct reciprocity is a powerful mechanism for cooperation in social dilemmas. The very logic of reciprocity, however, seems to require that individuals are symmetric, and that everyone has the same means to influence each others’ payoffs. Yet in many applications, individuals are asymmetric....

Being overweight or obese is associated with lower employment and earnings, possibly arising from employer discrimination. A few studies have used field experiments to show that obese job applicants are, in fact, discriminated against in the hiring process. However, whether overweight job...

We study a simple model of consumption of animals in which consumers exhibit altruism towards animals. Consumers can choose both the quantity and the quality of animal lives. This model gives rise to a public good problem: at the market equilibrium, quality is too low, and quantity is too high when...

We study the profitability of bundling by an upstream firm that licenses technologies to downstream competitors, and that faces competition for one of its technologies. In an otherwise standard “Chicago-style” model, the existence of downstream competition can make inefficient bundling profitable....
