High social status is often associated with greater mating opportunities and fertility for men, but do women also obtain fitness benefits of high status? Greater resource access and child survivorship may be principal pathways through which social status increases women's fitness. Here, we examine...

We study the welfare impact of revenue management, a practice which is widely spread in the transport industry, but whose impact on consumer surplus remains unclear. We develop a theoretical model of revenue management allowing for heterogeneity in product characteristics, capacity constraints,...

In this article, we extend the literature on merger simulation models by incorporating its potential synergy gains into structural econometric analysis. We present a three-step integrated approach. We estimate a structural demand and supply model, as in Bonnet and Dubois (2010). This model allows...

The paper proposes a five-step methodology based on the estimation of demand and supply models to test the existence of manufacturers’ collusive behaviour and evaluate its impact on market and welfare. This methodology allows for the estimation of profit sharing in vertical chains by properly...

Agriculture is one of the economic sectors most exposed to exogenous risks such as climate hazards and price volatility on agricultural markets. Agricultural policies targeting the adoption of environment-friendly but potentially risk-increasing practices cannot ignore this challenge. Farmers have...

Counterexamples to some old-standing optimization problems in the smooth convex coercive setting are provided. We show that block-coordinate, steepest descent with exact search or Bregman descent methods do not generally converge. Other failures of various desirable features are established:...

We consider an ad-financed media firm that chooses the ideological location of its news when consumers who directly receive the news can share it with their followers on social media. When the firm maximizes the breadth of news sharing, it tends to produce polarized news if the mean (the variance)...

Diagnostic tests allow better informed medical decisions when there is uncertainty about a patient’s health status and, therefore, about the desirability to undertake treatment. This paper studies the relation between the expected value of diagnostic information and a patient's risk aversion. We...

We consider dynamic competition among platforms in a market with network externalities. A platform that dominated the market in the previous period becomes “focal” in the current period, in that agents play the equilibrium in which they join the focal platform whenever such equilibrium exists. Yet...

We study the incidence of nonlinear labor income taxes in an economy with a continuum of endogenous wages. We derive in closed form the effects of reforming nonlinearly an arbitrary tax system, by showing that this problem can be formalized as an integral equation. Our tax incidence formulas are...
