Cournot games with biconcave demand
Ewerhart, Christian - 2014 - Revised version, January 2014
Biconcavity is a simple condition on inverse demand that corresponds to the ordinary concept of concavity after simultaneous parameterized transformations of price and quantity. The notion is employed here in the framework of the homogeneous-good Cournot model with potentially heterogeneous...

Mixed equilibria in Tullock contests
Ewerhart, Christian - 2014
Any symmetric mixed-strategy equilibrium in a Tullock contest with intermediate values of the decisiveness parameter ("2 R ∞") has countably infinitely many mass points. All probability weight is concentrated on those mass points, which have the zero bid as their sole point of accumulation....

Chapter 44 Non-zero-sum two-person games
Raghavan, T.E.S. - In: Handbook of game theory with economic applications : …, (pp. 1687-1721). 2002
This chapter is devoted to the study of Nash equilibria, and correlated equilibria in both finite and infinite games. We restrict our discussions to only those properties that are somewhat special to the case of two-person games. Many of these properties fail to extend even to three-person...

Chapter 42 Foundations of strategic equilibrium
Hillas, John; Kohlberg, Elon - In: Handbook of game theory with economic applications : …, (pp. 1597-1663). 2002
This chapter examines the conceptual foundations of the concept of strategic equilibrium and its various variants and refinements. The emphasis is very much on the underlying ideas rather than on any technical details.After an examination of some pre-equilibrium ideas, in particular the concept...

Chapter 41 Strategic equilibrium
Van Damme, Eric - In: Handbook of game theory with economic applications : …, (pp. 1521-1596). 2002
This chapter of the Handbook of Game Theory (Vol. 3) provides an overview of the theory of Nash equilibrium and its …-enforcing theory of rational behavior in non-cooperative games. Given the assumption of independent behavior of the players, it follows … that a self-enforcing theory has to prescribe a Nash equilibrium, i.e., a strategy profile such that no player can gain by …

Diagonal payoff security and equilibrium existence in quasi-symmetric discontinuous games
Ewerhart, Christian - 2022
Previous evidence shows that better insurance coverage increases medical expenditure. However, formal studies on the effect of spending on health outcomes, and especially mental health, are lacking. To fill this gap, we reanalyze data from the Rand Health Insurance Experiment and estimate a...

All but one free ride when wealth effects are small
Silvestre, Joaquim - In: SERIEs : Journal of the Spanish Economic Association 3 (2012) 1/2, pp. 201-207
Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...
