Abstract
We study the emergence of norms of cooperation in experimental economies
populated by strangers interacting indefinitely. Can these economies achieve
full efficiency even without formal enforcement institutions? Which institutions
for monitoring and enforcement facilitate cooperation? Finally, what classes of
strategies do subjects employ? We find that, first, cooperation can be sustained
even in anonymous settings; second, some type of monitoring and punishment
institutions significantly promote cooperation; and, third, subjects mostly
employ strategies that are selective in punishment. (JEL C71, C73, D12, Z13)
