A number of case studies document the coexistence of significantly hig
h levels of compliance with low inspection frequencies. The present pa
per provides an explanation of this puzzle by analyzing a sequential g
ame where the enforcement activity is predicated on the (observable) l
evel of violations, and the agents anticipate the effect of their comp
liance decisions on the regulator. Such anticipatory behavior is shown
to result in higher levels of compliance at lower monitoring frequenc
ies compared to the equilibrium outcome of the corresponding simultane
ous move game.
