For games of contracting under perturbed best response dynamics, varying the perturbations along two dimensions (uniform vs. logit, directed vs. undirected) gives four possibilities. Three of these select differing major bargaining solutions as stochastically stable. The fourth possibility...

This study considers waiting times for populations to achieve efficient social coordination. Belloc and Bowles [1] conjecture that coalitional behavior will hasten such coordination. This turns out to be true when every member of the population interacts with every other member, but does not...

The ability to share intentions and adjust one's choices in collaboration with others is a fundamental aspect of human nature. We discuss the forces that would have acted for and against the evolution of this ability for a large class of dilemmas and coordination problems that would have been...

This study considers pure coordination games on networks and the waiting time for an adaptive process of strategic change to achieve efficient coordination. Although it is in the interest of every player to coordinate on a single globally efficient norm, coalitional behavior at a local level can...
