This note further characterizes the tacit collusion equilibria in the investment timing game of Boyer, Lasserre and Moreaux [1]. Tacit collusion equilibria may or may not exist, and when they do may involve either finite time investments (type 1) or infinite delay (type 2). The relationship...

The paper examines under what conditions vertically differentiated duopolists engage in first-degree price discrimination. Each firm decides on a pricing regime at a first stage and sets prices at a second stage. The paper shows that when unit cost is an increasing and convex function of...

This paper addresses the two-way implication between punctuality level of public transport and commuter behavior. We consider a modal competition between public transport and an alternative mode. Commuters may choose different strategies to minimize their journey cost. In particular, when the...

Recently, many contributions have focused on the relationship between capital accumulation, growth and population dynamics, introducing fertility choice in macro-dynamic models. In this paper, we go one step further highlighting also the link with pollution. We develop a simple overlapping...

This article investigates the latest developments in longevity risk modelling, and explores the key risk management challenges for both the financial and insurance industries. The article discusses key definitions that are crucial for the enhancement of the way longevity risk is understood;...

In 1996, two investigations conducted by the Securities and Exchange Commission and the American Department of Justice reported non-competitive practices among market makers on the NASDAQ. These reports also mentioned the influence of the NASDAQ social structure on market makers' behaviours....

We model the interaction between an employer and a worker with interdependent preferences in a simple one-shot production process. In particular, we assume that the worker becomes kinder if she senses that her employer is an altruist. We assume that intentions are private information. Thus, the...

Network users can choose among different security solutions to protect their data. Those solutions are offered by competing providers, with possibly different performance and price levels. In this paper, we model the interactions among users as a noncooperative game, with a negative externality...
