Determinants of equilibrium selection in network formation : an experiment

Hoyer, Britta; Rosenkranz, Stephanie - In: Games 9 (2018) 4/89, pp. 1-25

Theoretical models on network formation focus mostly on the stability and efficiency of equilibria, but they cannot deliver an understanding of why specific equilibrium networks are selected or whether they are all actually reachable from any starting network. To study factors affecting...

Homophily and social norms in experimental network formation games

Arifovic, Jasmina; Danese, Giuseppe - In: Games 9 (2018) 4/83, pp. 1-22

Field studies of networks have uncovered a preference to befriend people we perceive as similar according to some dimensions of our identity (“homophily”). Lab studies of network formation games have found that adherence to social norms of reciprocity and inequity aversion are also drivers...

Endogenous network formation in local public goods : an experimental analysis

Chen, Ying; Lane, Tom; Macdonald, Stuart - 2023 - This version: March 2, 2023

We experimentally explore public good production levels, and the endogenous formation of network structures to facilitate output sharing, among agents with heterogeneous production costs or valuations. Results corroborate the key theoretical insights of Kinateder & Merlino (2017) characterizing...

Forward-looking behavior in Hawk–Dove games in endogenous networks: Experimental evidence

Berninghaus, Siegfried K.; Ehrhart, Karl-Martin; Ott, Marion - In: Games and Economic Behavior 75 (2012) 1, pp. 35-52

We conduct an experiment in continuous time: every subject can change her links to others and her action in a Hawk–Dove game, which she plays bilaterally with each of her linked partners, at any time. We hypothesize that norms exist regarding who establishes and thus pays for links, and that...

Determinants of in-group bias: group affiliation or guilt-aversion?

Güth, Werner; Ploner, Matteo; Regner, Tobias - 2008

In-group favoritism in social dilemma situations is one of the main findings of studies in Social Identity Theory. We investigate what causes the in-group bias: is it due to mere group affiliation or, alternatively, is guilt-aversion a possible explanation? We induce group membership in a...

Increasing Altruistic and Cooperative Behaviour with Simple Moral Nudges

Capraro, Valerio - 2019

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...
