Status-seeking in hedonic games with heterogeneous players
Lazarova, Emiliya A.; Dimitrov, Dinko - 2010
characterize the core as a function of the utility's parameter values and show that in all cases the corresponding cores are non …-empty. We further discuss the core stable outcomes in terms of their segregating versus integrating properties. -- Coalitions … ; Core ; Stability ; Status-seeking …

On the nonemptiness of approximate cores of large games
Allouch, Nizar; Wooders, Myrna Holtz - 2014
We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...

Multilateral bargaining in networks : on the prevalence of inefficiencies
Lee, Joosung - 2015
We introduce a noncooperative multilateral bargaining model for a network-restricted environment, in which players can communicate only with their neighbors. Each player strategically chooses the bargaining partners among the neighbors to buy out their communication links with upfront transfers....

Pairing games and markets
Alkan, Ahmet; Tuncay, Alparslan - 2014
Pairing Games or Markets studied here are the non-two-sided NTU generalization of assignment games. We show that the Equilibrium Set is nonempty, that it is the set of stable allocations or the set of semistable allocations, and that it has several notable structural properties. We also...

Paths to stability in two-sided matching with uncertainty
Lazarova, Emiliya A.; Dimitrov, Dinko - 2013
We consider one-to-one matching problems under two modalities of uncertainty that differ in the way types are assigned to agents. Individuals have preferences over the possible types of the agents from the opposite market side and initially know the "name" but not the "type" of the other...

Media and social capital
Campante, Filipe R.; Durante, Ruben; Tesei, Andrea - 2021
We survey the empirical literature in economics on the impact of media technologies on social capital. Motivated by a simple model of information and collective action, we cover a range of different outcomes related to social capital, from social and political participation to interpersonal...

The set of equilibria in max-min two groups contests with binary actions and a private good prize
Gilli, Mario; Sorrentino, Andrea - 2024
In this paper we consider a deterministic complete information two groups contest where the effort choices made by the teammates are aggregated into group performance by the weakest-link technology (perfect complementarity), that is a "max-min group contest", as defined by Chowdhury et al....

Effort provision and incentivisation in tullock group-contests with many groups : an explicit characterisation
Bosco, Davide; Gilli, Mario - 2024
We study effort provision and incentivisation in a Tullock group-contest with m ≥ 2 groups that differ in size. A novel algorithmic procedure is presented that, under a symmetry assumption, explicitly characterises the equilibrium. Endogenous, optimal incentivisation schemes are then...
