Superstars need Social Benefits: An Experiment on Network Formation

van Leeuwen, Boris; Offerman, Theo; Schram, Arthur - 2013

social benefits are highly important. They facilitate convergence to equilibrium networks and enhance the stability and … which the core contributes more than expected in the stage-game equilibrium. We show that this result is predicted by a … repeated game equilibrium. …

Network Formation with Heterogeneous Players

Galeotti, Andrea; Goyal, Sanjeev - 2002

robust features of equilibrium networks. We find that in a society with many groups, where it is cheaper to connect within …

Network Formation under Heterogeneous Costs: The Multiple Group Model

Kamphorst, Jurjen; van der Laan, Gerard - 2004

It is widely recognized that the shape of networks influences both individual and aggregate behavior. This raises the question which types of networks are likely to arise. Our paper fits into the literature that addresses this question. The paper continues on the work of Galeotti, Goyal and...

Can Communication Mitigate Strategic Delays in Investment Timing?

Mermer, Ayse Gül; Onderstal, Sander; Sonnemans, Joep - 2023

In economic environments, decision-makers can strategically delay irreversible investments to learn from the actions of others. This creates free-riding incentives and can lead to socially suboptimal outcomes. We experimentally examine if and how communication mitigates this free-riding problem...

Fairness and Reciprocity in the Hawk-Dove Game

Neugebauer, Tibor; Poulsen, Anders; Schram, Arthur J.H.C. - 2002

We study fairness and reciprocity in a Hawk-Dove game. This alllows us to testvarious models in one framework. We observe a large extent of selfish and rationalbehavior. Our results are inconsistent with leading models in this field.

Does Stake Size matter for Cooperation and Punishment?

Kocher, Martin G.; Martinsson, Peter; Visser, Martine - 2006

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that an increase in stake size does neither significantly affect cooperation nor, interestingly, the level of punishment.

The Economics of Altruistic Punishment and the Demise of Cooperation

Egas, Martijn; Riedl, Arno - 2005

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

Perfection and Stability of Stationary Points with Applications to Noncooperative Games

van der Laan, Gerard; Talman, Dolf; Yang, Zaifu - 2002

well known refinements of the Nash equilibrium, namely, perfect Nash equilibrium and proper Nash equilibrium, are special … Nash equilibrium is shown to exist for every game. In symmetric bimatrix games, our results imply the existence of a … symmetric proper equilibrium. Applying our results to the field of evolutionary game theory yields a refinement of the …

Aversion to Health Inequality - Pure, Income-Related and Income-Caused

Robson, Matthew; O'Donnell, Owen; Van Ourti, Tom - 2023

We design a novel experiment to identify aversion to pure (univariate) health inequality separately from aversion to income-related and income-caused health inequality. Participants allocate resources to determine health of individuals. Identification comes from random variation in resource...
