This article examines the nature of human behavior in a nested socialdilemma referred to as the Spillover Game. Players are divided into twogroups with positive production interdependencies. Based on theoreticallyderived opportunistic, local, and global optima, our experimental...

Although one may hope to achieve equality of stated profits withoutenforcing it, one may not trust in such voluntary equality seeking andrather try to impose rules (of bidding) guaranteeing it.[...]

We run a computerised experiment of network formation where allconnections are bene…cial and only direct links are costly. Players simul-taneously submit link proposals; a connection is made only when bothplayers involved agree. We use both simulated and experimentally gen-erated data to test...
