Technology Transfer under Asymmetric Information
用信号传递模型解释专利许可合同为何采用固定费或提成费、是否排他等不同形式，揭示发明人事前信息优势与模仿风险如何影响合同设计。
Licensing contracts for newly patented innovations are observed to vary along several dimensions, including the form and size of the payment to the inventor (fixedfee versus some output-based royalty), the degree of exclusivity, and the division of rents. In this article, we show that theform of the contract can be explained by two problems in technology exchange: the superiority of a licensor's precontractual information about the economic value of the innovation and thefact that sharing this information with the licensee mayfacilitate imitation. We show that a licensor signals her technology type with an output-based payment (or royalty) and may leave some of the rents with the licensee. Conditions under which exclusive license contracts (linear and nonlinear) and nonexclusive linear contracts are used to transfer technology are identified.
