The strategic choice of managerial incentives is studied in a multi-ag
ent setting using a two-stage game. In the first stage, the principal
chooses incentive schemes. Then, agents make their decisions. The game
models the structure of multidivisional firms; divisions (agents) are
managed independently, but the general office (principal) monitors th
eir performance and provides incentives. It explains the rationale for
establishing either cooperation or competition across divisions if fi
rms face Cournot competition. If divisions are linked because of techn
ological reasons (positive spillovers) cooperation should be stimulate
d. If they sell substitute products (negative spillovers) competition
is needed.
