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...

This paper examines the temporal effects of alternative procedures for controlling sales force effort, particularly when the effect of such effort is felt in both current and future periods. Related informational requirements for both firm and salesmen are also discussed in terms of nonzero sum...

This paper deals with measurement practices and expertises in both manufacturing and service industries. It states that the issue of 'what to measure' still needs further research and discussion, even though there is a general acceptance that the key operational performances of a production...

This paper considers an individual's problem and effects on savings for retirement. We show using a deterministic model, a linear utility function and assuming an individual can benefit from a tax break in savings, that under reasonable circumstances, there is only one switch from not saving to...

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...

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...
