It is well known that a pure-strategy Nash equilibrium does not exist for a two-player rent-seeking contest when the contest success function parameter is greater than two. We analyze the contest using the concept of equilibrium in secure strategies, which is a generalization of the Nash...

We study the classical problem of spatial competition between two players with linear transport costs proposed by (Hotelling, 1929). We employ the concept of the equilibrium in secure strategies (ESS). The reviewed definitions of the ESS and of the best secure response are presented. The set of...

A new concept of equilibrium in secure strategies (EinSS) in non-cooperative games is presented. The EinSS coincides with the Nash-Cournot Equilibrium when Nash-Cournot Equilibrium exists and postulates the incentive of players to maximize their profit under the condition of security against...
