This paper uses the block-booking film exhibition contracts that were the s
ubject of Paramount to examine the role of contract terms in facilitating s
elf-enforcing relationships. Because of the large uncertainty in film value
at the time of contracting, it is difficult to fully specify optimal exhib
itor performance (such as exhibition run length) ex ante. Instead, the effi
cient contractual arrangement contractually overconstrains exhibitors and r
elies on the superior reputational capital of distributors to flexibly adju
st contract terms ex post. The analysis illustrates that, rather than think
ing of contracts as either court enforced or self-enforced, transactors gen
erally combine court-enforced and self-enforced sanctions by using contract
terms to economize on their limited reputational capital. Block booking is
explained within this framework by its effects on reducing the variance in
the value of the film package and, therefore, the demands placed on the di
stributors' reputational capital.
