Interfirm strategic alliances (ISAs) are proliferating rapidly. The mi
xed motive-competitive and cooperative-nature of ISAs is hypotheticall
y captured by the prisoner's dilemma (PD) model. Until now, empirical
research in realistic business settings into the payoff structure obta
ined in ISAs has been lacking. After examining the incentives inherent
in the PD payoff structure, this study presents the results of a US n
ationwide mail survey of 342 senior executives recently involved in IS
As. The results corroborate the existence of a payoff structure which
satisfies the PD payoff structure. Some implications for promoting coo
perative behavior as well as future research directions are discussed.
