the shapley value, one of the most common solution concepts of cooperative game theory is defined and axiomatically characterized in different game-theoretic models. certainly, the shapley value can be used in interesting sharing cost/reward problems in the operations research area such as connection, routing, scheduling, production and inventory situations. in this paper, we focus on the shapl...

in this paper, we show that for any finite order entire function $f(z)$, the function of the form $f(z)^{n}[f(z+c)-f(z)]^{s}$ has no nonzero finite picard exceptional value for all nonnegative integers $n, s$ satisfying $ngeq 3$, which can be viewed as a different result on hayman conjecture. we also obtain some uniqueness theorems for difference polynomials of entire functions sharing one comm...

BACKGROUND Little is known about the effect of different forms of patient cost-sharing on the utilization of clinical preventive services or if the effect varies by type of health plan. OBJECTIVES To assess empirically the relationships between the utilization of recommended preventive services and different forms of patient cost-sharing and how the effect is mediated by type of preventive se...

in an economy based on knowledge, organizations use their employees’ knowledge as a resource for creating and increasing organizational value and their success depends on their ability to manage their rare and volatile resources. one of the important organizational capabilities is social capital which can greatly help organizations to create and share knowledge as well as to create “permanent o...

We identify how to share costs locally in weighted congestion games with polynomial cost functions to minimize the worst-case price of anarchy (POA). First, we prove that among all cost-sharing methods that guarantee the existence of pure Nash equilibria, the Shapley value minimizes the worst-case POA. Second, if the guaranteed existence condition is dropped, then the proportional cost-sharing ...

Purpose – This paper aims to examine how knowledge sharing behavior is influenced by three sets of dynamics: a rational calculus that weighs the costs and benefits of sharing; a dispositional preference that favors certain patterns of sharing outcomes; and a relational effect based on working relationships. Design/methodology/approach – Concepts from social exchange theory, social value orienta...

Value-based insurance design programs have focused on reducing consumer cost sharing in health insurance for preventive tests and medications for chronic diseases. But for value-based design principles to have a stronger clinical and economic impact, they should be extended to expensive services and to those for which the evidence is limited or controversial. This paper proposes applying value-...

A growing number of companies are considering whether they can reduce overall medical costs by improving drug compliance through value-based pharmacy benefit designs. Value-based designs either provide more generous coverage for certain clinically proven drugs, or change cost-sharing or copayment levels for drugs used to treat the employee population's most widespread and costly chronic medical...
