it does not reach an equilibrium within 12 time pe riods. Once the equilibrium
is reached, only defectors are left. The results are depicted in Figure 16.9.
We have so far seen only what may tip the scale towards equilibrium of
defection with only defectors present. But what will help to sustain equilibrium of cooperators and enforcers? The parameters that will help sustain
equilibrium are, for instan ce , th e level of punishment and the cos t of en3: Fe
