The purpose of this paper is to consider a partial equilibrium model for a sustainable infrastructure investment in a labor-production economy. We consider an inter-temporal Stackelberg game in a "capital primitive" economy where all capital investments are made by a Central Agency (a...

This paper considers a memory-based persistent counting random walk, based on a Markov memory of the last event. This persistent model is a different than the Weiss persistent random walk model however, leading thereby to different results. We point out to some preliminary result, in particular,...

This paper establishes the case for a fallacy of economies of scale in large aggregate institutions and the effects of scale risks. The problem of rogue trading and excessive risk taking is taken as a case example. Assuming (conservatively) that a firm exposure and losses are limited to its...

[fre] Investissements, utilisation de capacité productive et dépréciation: politiques optimales. . En appliquant la théorie de commande optimale à un modèle dynamique de l'entreprise, il est possible de déterminer les politiques optimales en matière d'investissements, d'utilisation de...

This paper considers a multi-firms advertising model under uncertainty of the Nerlove-Arrow type. It is shown (under a Markovian assumption of the advertising process) that the probability of sales for a firm in a multi-firms setting is given by a Poisson distribution with a parameter given by...

We model the effect of contract parameters such as price rebates and after-sales warranty costs on the choice of quality by a supplier, the inspection policy of a producer, and the resulting end product quality. Both noncooperative and cooperative settings are explored. The paper's contribution...

The purpose of this article is to consider a two firms excess-loss reinsurance problem. The first firm is defined as the direct underwriter while the second firm is the reinsurer. As in the classical model of collective risk theory it is assumed that premium payments are received...

A dispatching problem with random availability of vehicles and options to send rented vehicles is considered. We assume passenger arrivals to be described by a pure-birth process. Such a problem is analytically attractive and is shown to have practical applications in vehicle dispatching models....

We consider a retailer who orders products before the price for them becomes known. The price is an outcome of perfect competition in a complete market. Since the demand is price sensitive, the uncertainty in prices induces uncertain profits and associated risks. In this paper we show that if...
