Equilibria in secure strategies in the Tullock contest
ISKAKOV, Mikhail; ISKAKOV, Alexey; ZAKHAROV, Alexey - Center for Operations Research and Econometrics (CORE), … - 2014
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...

Equilibrium in secure strategies
iskakov, Mikhail; ISKAKOV, Alexey - Center for Operations Research and Econometrics (CORE), … - 2012
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...

On Gale and Shapley ‘College admissions and stability of marriage’
GABSZEWICZ, Jean J.; GARCIA, Filomena; PAIS, Joana; … - Center for Operations Research and Econometrics (CORE), … - 2008
In this note, we start to claim that established marriages can be heavily destabilized when the population of existing couples is enriched by the arrival of new candidates to marriage. Afterwards, we discuss briefly how stability concepts can be extended to account for entry and exit phenomena...

State-Dependent Utility and Decision Theory.
Dreze, J.H.; Rustichini, A. - Center for Operations Research and Econometrics (CORE), … - 2000
This survey paper prepared for the Handbook of Utility Theory covers the axiomatic foundation of decision making under uncertainty when conditional preferences are allowed to be state dependent, leading to an expected state-dependent utility representation.

Saddle functions and robust sets of equilibria
NORA, Vladyslav; UNO, Hiroshi - Center for Operations Research and Econometrics (CORE), … - 2012
This paper introduces games with a saddle function. A saddle function is a real valued function on the set of action profiles such that, for one player, minimizing the function implies choosing her best-response, and, for the other players, maximizing it implies choosing their best-responses. We...

Oligopolistic competition with general complementarities
CALCIANO, Filippo L. - Center for Operations Research and Econometrics (CORE), … - 2011
In this paper we extend the basic model of Cournot competition to the case where both the demand function and the cost functions of each firm depend on the amounts produced by competitors. In this modified setting, proving existence of equilibria becomes harder. We develop a generalization of...

Constitutions and social networks
MAULEON, Ana; ROEHL, Nils; VANNETELBOSCH, Vincent - Center for Operations Research and Econometrics (CORE), … - 2014
The objective of the paper is to analyze the formation of social networks where individuals are allowed to engage in several groups at the same time. These group structures are interpreted here as social networks. Each group is supposed to have specific rules or constitutions governing which...

Stochastic signaling: information substitutes and complements
TRUYTS, Tom - Center for Operations Research and Econometrics (CORE), … - 2012
I develop a model of stochastic costly signaling in the presence of exogenous imperfect information, and study whether equilibrium signaling decreases ('information substitutes') or increases ('information complements') if the accuracy of exogenous information increases. A stochastic pure costly...

On the timing of tax and investment in fiscal competition models
Hindriks, Jean; Nishimura, Yukihiro - Center for Operations Research and Econometrics (CORE), … - 2014
earlier theory, we show that regions prefer to choose investment before taxes. We also show that sequential choice of taxes is … preferable to simultaneous choice of taxes, and that modulo sufficient asymmetry among regions, the simultaneous choice of … investment is preferable to the sequential choice of investments. Our theoretical prediction is that both taxes and public …

Price Symmetry in a Duopoly with Congestion.
Haimanko, O.; Steinberg, R. - Center for Operations Research and Econometrics (CORE), … - 2000
We show that in a duopoly operating in a congested market, with a general congestion function and an arbitrary distribution of consumer disutility for congestion, there cannot exist an asymmetrict Nash equilibrium. We also show tha whenever an equilibrium does exisq it is unique. Closed...
