Nous proposons un survol de travaux récents sur la concurrence entre vendeurs lorsqu'il y a sélection adverse et non-exclusivité, c'est-à-dire que l'acheteur peut simultané- ment échanger avec plusieurs vendeurs. Nous montrons que la sélection adverse favorise les tarifs convexes, qu'un tarif...

We introduce a novel approach addressing global analysis of a difficult class of nonconvexnonsmooth optimization problems within the important framework of Lagrangian-based methods. This genuine nonlinear class captures many problems in modern disparate fields of applications. It features complex...

The convergent evolution of the human pygmy phenotype in tropical rainforests is widely assumed to reflect adaptation in response to the distinct ecological challenges of this habitat (e.g. high levels of heat and humidity, high pathogen load, low food availability, and dense forest structure), yet...

Promoting the adoption of public goods that are not yet widely accepted is particularly challenging. This is because most tools for increasing cooperation—such as reputation concerns1 and information about social norms2—are typically effective only for behaviours that are commonly practiced, or at...

This paper reports that the econometric findings of Azam & Thelen (2010) remain valid when the sample is extended by 10 years to cover 1990–2014 in Azam & Thelen (2018). They blame the presence of US troops in oil-exporting countries and their neighbors for increasing transnational...

We solve a version of the analytical Real Business Cycle (RBC) model with a predetermined rate of return on household saving. The solution differs from that of the benchmark RBC model along two dimensions: (i) Policy functions depend on the variance of the technology shock. (ii) There is a...

Firms often sell a basic good as well as ancillary ones. Hold-up concerns have led to ancillary good regulations such as transparency and price caps. The hold-up narrative, however, runs counter to evidence in many retail settings where ancillary good prices are set below cost (e.g. free shipping,...
