Efficient contracts set incentives through the assignment of rights an
d profit shares. Although efficient contracts have been used to explai
n the nature of the firm, the use of contractual rights in specific bu
siness contracts is relatively unexplored. We analyze contractual righ
ts in franchise systems, in particular the right to add franchisees. A
n exclusive territory assigned to an initial franchisee is not an immu
table guarantee, but rather a starting point for subsequent renegotiat
ion in the franchise relationship. Exclusivity is therefore profitable
when franchisee efforts are critical to the venture. A sample of fran
chise contracts reveals evidence consistent with the model's predictio
n.
