We provide requirements on constitutions and players …, therefore, have influence on the stability of the job market …

(Anti-) Coordination in Networks

Kovarik, Jaromir; Mengel, Friederike; Romero, J. Gabriel - 2010

We study (anti-) coordination problems in networks in a laboratory experiment. Participants interact with their neighbours in a fixed network to play a bilateral (anti-) coordination game. Our main treatment variable is the extent to which players are heterogeneous in the number of connections...

How Homophily Affects the Speed of Learning and Best Response Dynamics

Golub, Benjamin - 2012

We examine how the speed of learning and best-response processes depends on homophily: the tendency of agents to associate disproportionately with those having similar traits. When agents' beliefs or behaviors are developed by averaging what they see among their neighbors, then convergence to a...

Myopic or Farsighted? An Experiment on Network Formation

Mantovani, Marco - 2011

Pairwise stability (Jackson and Wolinsky, 1996) is the standard stability concept in network formation. It assumes … agents are farsighted, related stability concepts have been proposed. We design a simple network formation experiment to test … these theories. Our results provide support for farsighted stability and strongly reject the idea of myopic behavior …

Cooperation Through Imitation and Exclusion In Networks

Fosco, Constanza - 2009

We develop a simple model to study the coevolution of interaction structures and action choices in Prisoners' Dilemma games. Agents are boundedly rational and choose both actions and interaction partners via payoff-based imitation. The dynamics of imitation and exclusion yields polymorphic...

Trust and Manipulation in Social Networks

Foerster, Manuel; Mauleon, Ana; Vannetelbosch, Vincent J. - 2014

We investigate the role of manipulation in a model of opinion formation. Agents repeatedly communicate with their neighbors in the social network, can exert effort to manipulate the trust of others, and update their opinions about some common issue by taking weighted averages of neighbors'...

Networks of Military Alliances, Wars, and International Trade

Jackson, Matthew O.; Nei, Stephen - 2015

We investigate the role of networks of alliances in preventing (multilateral) interstate wars. We first show that, in the absence of international trade, no network of alliances is peaceful and stable. We then show that international trade induces peaceful and stable networks: trade increases...

Naive Learning in Social Networks : Convergence, Influence and Wisdom of Crowds

Jackson, Matthew O.; Golub, Benjamin - 2012

We study learning and influence in a setting where agents communicate according to an arbitrary social network and naively update their beliefs by repeatedly taking weighted averages of their neighbors' opinions. A focus is on conditions under which beliefs of all agents in large societies...

Von Neumann-Morgenstern Farsightedly Stable Sets in Two-Sided Matching

Vannetelbosch, Vincent J.; Mauleon, Ana; Vergote, Wouter - 2008

We adopt the notion of von Neumann-Morgenstern farsightedly stable sets to predict which matchings are possibly stable when agents are farsighted in one-to-one matching problems. We provide the characterization of von Neumann-Morgenstern farsightedly stable sets: a set of matchings is a von...

Extrapolation in Games of Coordination and Dominance Solvable Games

Mengel, Friederike; Sciubba, Emanuela - 2011

We study extrapolation between games in a laboratory experiment. Participants in our experiment first play either the dominance solvable guessing game or a Coordination version of the guessing game for five rounds. Afterwards they play a 3x3 normal form game for ten rounds with random matching...
