This article is devoted to various methods (optimal transport, fixed-point, ordinary differential equations) to obtain existence and/or uniqueness of Cournot–Nash equilibria for games with a continuum of players with both attractive and repulsive effects. We mainly address separable situations but...

The EU mandated a single standard for second generation wireless telecommunications, whereas the US allowed several incompatible standards to battle for market share. Motivated by this example, we argue that a single standard leads to a free riding problem, and thus to a significant decrease in...

Two types of intrinsically motivated workers are considered: “good” workers care about the mission of an organization, whereas “bad” workers derive pleasure from destructive behavior. Compared to the case with only good motivated workers, the mission-oriented sector has to resort to higher...

We study exchanges between three overlapping generations with non-dynastic altruism. The middleaged choose informal care provided to their parents and education expenditures for their children. The young enjoy their education, while the old may leave a bequest to their children. Within each period...

We consider a model of cost-based procurement in which the principal faces Knightian uncertainty about the agent's preferences for cost reduction. We show that a particularly simple incentive scheme—a menu comprising a fixed-price contract and a cost-reimbursement contract—minimizes the maximum...

The epidemiological transition has provided the theoretical background for the expectation of convergence in mortality patterns. We formally test and reject the convergence hypothesis for a sample of industrialized countries in the period from 1960 to 2008. After a period of convergence in the...

Nonparametric estimation methods are experiencing a growing success in their application in economics. This success comes from the fact that they do not imply any assumption about the object to estimate: probability density function, regression model… and let the data determine an appropriate model...

This paper investigates whether a search engine’s ordering of algorithmic results has an important effect on website traffic. A website’s ranking on a search engine results page is positively correlated with the clicks that it receives. This could result from the search engine’s accurately...

We study two-player contests in which, in order to win a prize, each player hires a delegate to expend effort on her behalf; neither party's delegation contract is revealed to the rival party when the delegates choose their effort levels. We obtain first the outcomes of this unobservable-contracts...
