Group selection: The quest for social preferences
Salomonsson, Marcus - 2009
This paper surveys the literature on group selection. I describe the early contributions and the group selection controversy. I also describe the main approaches to group selection in the recent literature; fixation, assortative group formation, and reproductive externalities.

Anticipated verbal feedback induces altruistic behavior
Ellingsen, Tore; Johannesson, Magnus - 2007
A distinctive feature of humans compared to other species is the high rate of cooperation with non-kin. One explanation is that humans are motivated by concerns for social esteem. In this paper we experimentally investigate the impact of anticipated verbal feedback on altruistic behavior. We...

Genetic influences on economic preferences
Cesarini, David; Dawes, Christopher T.; Johannesson, Magnus - 2007
In this paper, we use the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving. Using standard methods from behavior genetics, we find strong prima facie evidence that these preferences are broadly heritable...

Do people care about context? Framing effects in dictator games
Dreber, Anna; Ellingsen, Tore; Johannesson, Magnus; … - 2011
Many previous experiments document that behavior in multi-person settings responds to the name of the game and the labeling of strategies. Usually these studies cannot tell whether frames affect preferences or beliefs. In this Dictator game study, we investigate whether social framing effects...

Natural selection and social preferences
Weibull, Jörgen; Salomonsson, Marcus - Economics Institute for Research (SIR), … - 2005
A large number of individuals are randomly matched into groups, where each group plays a finite symmetric game. Individuals breed true. The expected number of surviving offspring depends on own material payoff, but may also, due to cooperative breeding and/or reproductive competition, depend on...

Genetic Variation in Preferences for Giving and Risk-Taking

Optimality and equilibrium for binary decision problems in a committee
Laslier, Jean-François; Weibull, Jörgen W. - 2008
states of the world. We characterize the optimal anonymous and deterministic voting rule and provide a homogeneity assumption … on preferences and beliefs under which sincere voting is a Nash equilibrium for this rule. We also provide a necessary … and sufficient condition for sincere voting to be an equilibrium under any deterministic majoritarian voting rule. We show …
