We consider a duopoly competing in quantity, where firms can invest in both innovative and absorptive R&D to reduce their unit production cost, and where they benefit from free R&D spillovers between them. We analyze the case where firms act non cooperatively and the case where they cooperate by...

In this paper we develop a model to analyze, in a dynamic framework, how countries join international environmental agreements (IEAs). In the model, where countries suffer from the same environmental damage as a result of the total global emissions, a non-signatory country decides its emissions...

This paper analyzes competition between mutual funds in a multiple funds version of the model of Hugonnier and Kaniel [18]. We characterize the set of equilibria for this delegated portfolio management game and show that there exists a unique Pareto optimal equilibrium. The main result of this...

In this article, we use a simple mean-variance set up, where two symmetric Â…firms are competing in quantities, and investigate the impact of demand variability on the stability of collusion.

Unlike delta-hedging or similar methods based on Greeks, global hedging is an approach that optimizes some terminal criterion that depends on the difference between the value of a derivative security and that of its hedging portfolio at maturity or exercise. Global hedging methods in discrete...

We ask whether young agents prefer to work in different-age or same-age production pairs in an overlapping-generations model where wages are reputation-based. We find that inter-generational teams (i) produce more heterogeneity in the old workers' reputations, (ii) generate a greater share of...

This paper studies the informational content of elective teams in a dynamic principal/multiple-agents framework with adverse selection. Two agents with different employment histories are paid their conditional expected marginal product. They observe their types (good or bad), and choose between...

The aim of this paper is to price options embedded in bonds in a Dynamic Programming (DP) framework, the focus being on call and put options with advance notice. The pricing of interest rate derivatives was usually done via trees or finite differences. Trees are not really very efficient as they...
