Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

Using a laboratory experiment, we examine whether voluntary monetary sanctions induce subjects to coordinate more efficiently in a repeated minimum effort coordination game. While most groups first experience inefficient coordination in a baseline treatment, the efficiency increases...

Coordination games with Pareto-ranked equilibria have attracted major theoretical attention over the past two decades. Two early path-breaking sets of experimental studies were widely interpreted as suggesting that coordination failure is a common phenomenon in the laboratory. We identify the...
