The present paper considers a dynamic nonzero-sum game between drug de
alers and the authorities. Although the game is neither linear-quadrat
ic nor degenerate, in the sense that the closed-loop equilibria coinci
de with the open-loop equilibria, we are able to calculate explicitly
a stationary feedback Nash equilibrium of that game. In a numerical ex
ample, we determine the optimal allocation of governmental efforts bet
ween treatment and law enforcement minimizing the total discounted cos
t stream in the equilibrium. Moreover, we provide sensitivity analyses
with respect to the efficiency parameters of both competitors. Our re
sults show that a farsighted authority should attack the drug problem
from the demand side and put much effort in treatment measures and the
improvement of the efficiency of the treatment.
