game theory is an approach based on mathematics to study social interactions and modeling strategic situations. this theory focuses on decision situations where preferences of decision makers are disputed. existence of strategic position in city also with a conflict of interest or competition makes using game theory to describe the urban management issues, attractive. one of the important contr...

Based on the fact that T-mall and JD.com, two major e-commerce platforms, reduce prices significantly every year in shopping festival, but still can obtain high profits, this paper explains causes profit mechanism from perspective of game theory. Meanwhile, article builds a Bertrand model to analyze firms. The Nash equilibrium is (Discount, Discount) until they drop their 0, which obviously aga...

Sharing of spectrum has been identified as a key requirement in cognitive radio networks(CRNs). We address the problem of spectrum sharing with spectrum pricing where the primary user wants to sell the spectrum to the secondary users. By equilibrium pricing scheme, each of the players in the spectrum sharing game aims to take the strategy which maximize its own profit under sojourn-time constra...

In this paper, we develop a multitiered competitive supply chain network game theory model, which includes the supplier tier. The firms are differentiated by brands and can produce their own components, as reflected by their capacities, and/or obtain components from one or more suppliers, who also are capacitated. The firms compete in a Cournot-Nash fashion, whereas the suppliers compete a la B...

G that information technology (IT) security has emerged as an important issue in the last few years, the subject of security information sharing among firms, as a tool to minimize security breaches, has gained the interest of practitioners and academics. To promote the disclosure and sharing of cyber security information among firms, the U.S. federal government has encouraged the establishment ...

Previous research exploring the effect of corporate leniency programs has modelled the oligopoly stage game as a Prisoners’ Dilemma. Using numerical analysis, we consider the Bertrand price game and allow the probability of detection and penalties to be sensitive to firms’ prices. Consistent with earlier results, a maximal leniency program necessarily makes collusion more difficult. However, we...

We define a class of dynamic Markovian games, directional dynamic games (DDG), where directionality is represented by a strategy-independent partial order on the state space. We show that many games are DDGs, yet none of the existing algorithms are guaranteed to find anyMarkov perfect equilibrium (MPE) of these games, much less all of them. We propose a fast and robust generalization of backwar...
