In a strategic framework, combinators provide a fundamental mechanism for exercising control over rewriting. This type of control is based on the observation of the success or failure of strategy application. This paper describes a framework where information relating to the outcome of strategy application is stored in two internally maintained stacks. These stacks represent an implicit state w...

The business environment is currently characterized by intensified competition at both the national and firm levels. Many studies have shown that innovation positively affect firms in enhancing their competitiveness. Innovation is a dynamic process that requires a continuous, evolving, and mastered management. Evaluating the sustainability of overall innovation capability of a business is a maj...

Testing in groups can lead to great efficiencies in total testing cost when searching for individuals with some characteristic. If the presence of a blocking object can cause a group with a positive object to test negative, there is a need to find optimal pooling strategies to minimize the cost of testing and reduce the number of missed positive individuals. We develop application driven cost f...

We study the optimal harvesting of a renewable resource that cannot be continuously exploited, i.e. after the harvest the released space cannot be immediately reallocated to the resource. In the meantime, this space can be given an alternative use of positive utility. We consider a discrete time model over an infinite horizon with discounting, and characterize the optimality of two myopic polic...

The stylized model presented is an optimal control model of technology investment decision of a single product firm. The firm’s technology investment does not have only a long-run positive effect but also a short-run adverse effect on its sales volume. We examine the case of high adverse investment effects where the firm finally leaves the market but we have observed different life cycles till ...
