The problem of modeling claims occurring in periodic random environments is discussed in this paper. In the classical approach of risk theory, the occurrence of claims is modeled by counting processes that do not account for claims following a periodic pattern. The author discusses how the use of the classical approach to model a periodic portfolio might lead to the miscalculation of important ...

Many construction companies struggle with multi-project optimization and change despite adhering to normative project portfolio management instructions and best practices. One explanation is that managers lack extensive multi-project management experience from which to apply related theory to practical outcomes. This paper proposes a three-dimensional segmentation framework to guide companies w...

For a company in the software product business, it is essential to understand how to connect business management and software development [17] and employ a solid, value-based approach in its decisionmaking. However, software engineering literature (SE) commonly addresses what should be done at the “floor level” and leaves the link to business and product management unaddressed [14]. Also, exist...

The product line approach is a major reuse concept that has shown concrete commercial results over the past years. Product lines achieve reuse in the functionality and solution space, and thus improve quality, cycle time and cost. They are specifically promising in cases where many variants are produced almost simultaneously, such as in telecommunication systems. Though appealing, the concept i...

T number of firms carrying a cause-related product has significantly increased in recent years. We consider a duopoly model of competition between firms in two products to determine which products a firm will link to a cause. We first test the behavioral underpinnings of our model in two laboratory experiments to demonstrate the existence of both a direct utility benefit to consumers from cause...

We study an investor’s decision to switch from active portfolio management to passive management. This problem is mathematically modelled by a mixture of a consumption-portfolio selection problem and an optimal stopping problem. We assume that the investor has stochastic differential utility with ambiguity aversion and incurs utility loss from active portfolio management that can be avoided by ...
