Operating in an intellectual property world: knowledge sharing among plant breeders in Canada.

摘要

This paper examines the incentives for knowledge sharing in an industry where a public institution and a private firm develop new differentiated crop varieties and sell them to heterogeneous farmers. The decision of the public institution to either share their knowledge, or protect and cross-license their IP with the rival firm, is a strategic choice. While the profit-maximizing private research firms have an incentive to protect and secure their intellectual property (IP), under some conditions they choose to cross-license their technology rather than forgo access to the public IP. The budget constrained public firm, with an objective of maximizing farmers' welfare, can have an incentive to share its IP but under certain conditions has an incentive to incur transaction costs to protect and cross-license its technology to obtain access to the private technology. The theoretical model shows that public incentives to protect IP are likely to be stronger in a research industry with significant corporate presence. A survey of Canadian wheat and canola breeders reveals that public breeders are far more secretive in the canola sector than in the wheat sector, a dichotomy that is consistent with the theoretical results.
