We analyze an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

We investigate how group boundaries, and the economic environment surrounding groups, affect altruistic cooperation and punishment behavior. Our study uses experiments conducted with 525 officers in the Swiss Army, and exploits random assignment to platoons. We find that, without competition...

We examine experimentally two different types of trust: trust in another party's cooperation and trust in ability. In the cooperation condition, player A sends x {0, X} to player B. The amount x is multiplied by c = 3, and B can return y {0,3x}. (...)

We examine experimentally two different types of trust: trust in another party's cooperation and trust in ability. In the cooperation condition, player A sends x{0,X} to player B. The amount x is multiplied by c=3, and B can return y{0,3x}. IN teh ability conditions, c depends on B's performance...

We show in a public goods experiment on three continents that conditional cooperation is a universal behavioral regularity. Yet, the number of conditional cooperators and the extent of conditional cooperation are much higher in the U.S.A. than anywhere else. -- conditional cooperation ; public...

We examine gender differences in trust in another party's cooperation (CC) or its ability (AC). While men and women do not differ concerning trust in cooperation, gender has a strong influence when trust in another subject's ability is required. -- trust ; gender ; experiment ; cooperation ;...
