Systematic empirical evidence on the consequences of incomplete contracts i
s meagre, because contracts are often classified as business secrets, and a
re accordingly difficult to obtain for research purposes. In this study we
employ the extensive information from the life of a Finnish research joint
venture, Micronas, during 1980-1992 to cast light on this issue. Of particu
lar interest is the principal-agent relationship between the owners and the
management of the research joint venture. Our investigation confirms the s
trong message of the incomplete contract theory, Hold-up problems are perva
sive in R&D projects, and the allocation of power and ownership is importan
t to the success of the projects.
