many studies have been conducted to determine the efficiency of two-stage network structures in the recent years. the two-stage network with additional inputs to the second stage, in which the second stage is independent of the first stage are one of these structures. thus, there is a need for a model capable of calculating the efficiency of two-stage structures as well as efficiency of each st...

The prosperity of e-commerce has made more and businesses willing to enter the market, which also brought a series strategic collaboration between firms. This study considers game models with without platform retailer. An relative logistics service sharing advantages while retailer procurement advantages. We formulated multichannel supply chain consisting manufacturer two retailers explore feas...

a r t i c l e i n f o This paper analyzes the issue of leadership when two jurisdictions are engaged in tax competition and capital tax revenues are used to finance the provision of local public goods. For that purpose we consider a timing game between the two asymmetric jurisdictions. On the first stage jurisdictions decide to move early or late and on the second stage they choose their tax ra...

Choosing a hard-to-guess secret is a prerequisite in many security applications. Whether it is a password for user authentication or a secret key for a cryptographic primitive, picking it requires the user to trade-off usability costs with resistance against an adversary: a simple password is easier to remember but is also easier to guess; likewise, a shorter cryptographic key may require fewer...

This paper demonstrates that in a duopoly model with firms being concerned about profit as well as corporate social responsibility (CSR), the outcome of game may coincide with the Stackelberg outcome. We argue that owner of the firm may use CSR orientation as a strategy to become Stackelberg leader in the quantity competition game.

Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...

While three deployed applications of game theory for security have recently been reported at AAMAS [12], we as a community remain in the early stages of these deployments; there is a continuing need to understand the core principles for innovative security applications of game theory. Towards that end, this paper presents PROTECT, a game-theoretic system deployed by the United States Coast Guar...

In economics duopoly is a market dominated by two firms large enough to influence the market price. Stackelberg presented a dynamic form of duopoly that is also called 'leader-follower' model. We give a quantum perspective on Stackelberg duopoly that gives a backwards-induction outcome same as the Nash equilibrium in static form of duopoly also known as Cournot's duopoly. We find two qubit quan...
