Intelligence and personality significantly affect social outcomes of individuals. We study how and why these traits affect the outcome of groups, looking specifically at how these characteristics operate in repeated interactions providing opportunity for profitable cooperation. Our experimental...

In this paper, we first replicated Harrison et al. (2012). Then, we studied if the group’s size has an impact on group’s risk aversion. In line with Harrison et al. (2012), our results confirm that no significant differences occur between individuals and groups risk aversion in three-person...

In the laboratory experiment reported in this paper we explore how evolving institutions and social norms, which we label 'culture', change individuals' preferences and behaviour in mainland China. From 1949 China experienced dramatic changes in its socio-economic institutions. These began with...

Before a group can take a decision, its members must agree on a mechanism to aggregate individual preferences. In this paper we present the results of an experiment on the influence of private payoff information and the role of the available alternatives on individuals' mechanism choices in such...

We examine the impact of behavioral noise on equilibrium selection in a hawk-dove game with a model that linearly interpolates between the one- and two-population structures in an evolutionary context. Perturbed best response dynamics generates two hypotheses in addition to the bifurcation...

It is still an open question when groups will perform better than individuals in intellectual tasks. We report that in a company takeover experiment, groups placed better bids than individuals and substantially reduced the winner's curse. This improvement was mostly due to peer pressure over the...

In minority games, players in a group must decide at each round which of two available options to choose, knowing that only subjects who picked the minority option obtain a positive reward. Previous experiments on the minority and similar congestion games have shown that players interacting...

When subjects interact in continuous time, their ability to cooperate may dramatically increase. In an experiment, we study the impact of different time horizons on cooperation in (quasi) continuous time prisoner's dilemmas. We find that cooperation levels are similar or higher when the horizon...

To investigate the relationship between the depth of strategic thinking and social preferences we ask subjects in an experiment to perform dictator games and a guessing game. The guessing game measures depth of strategic thinking while dictator games control for social preferences. When...

According to the Terror Management Theory, the fear of death may induce anxiety and threaten individual self-esteem. To remove this fear, individuals need to obtain and sustain self-esteem, for example by competing in rank order tournaments, or by focusing on status seeking. Within an...
