Nash equilibrium based fairness
Kameda, Hisao; Altman, Eitan; Touati, Corinne; Legrand, … - In: Mathematical Methods of Operations Research 76 (2012) 1, pp. 43-65
There are several approaches of sharing resources among users. There is a noncooperative approach wherein each user strives to maximize its own utility. The most common optimality notion is then the Nash equilibrium. Nash equilibria are generally Pareto inefficient. On the other hand, we...

Characterizations of the Existence of Nash Equilibria with Non-convex Strategy Sets
Nessah, Rabia; Kerstens, Kristiaan - IÉSEG School of Management, Université Catholique de Lille - 2008
A sufficient and necessary condition is presented for the existence of a Nash equilibrium in n-person noncooperative games in normal form where strategy sets are not necessarily convex. Under the convexity condition, we show that this new sufficient and necessary condition is a particular case...

Counterterrorism
Daniel G. Arce M.; Sandler, Todd - In: Journal of Conflict Resolution 49 (2005) 2, pp. 183-200
This article establishes the prevalence of deterrence over preemption when targeted governments can choose between either policies or employ both. There is a similar proclivity to favor defensive counter-terrorist measures over proactive policies. Unfortunately, this predisposition results in an...

Understanding Fixed Point Theorems
Arnold, Lutz G. - Wirtschaftswissenschaftliche Fakultät, Universität … - 2003
Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of drawing and shifting curves in the plane and is,...
