Screening and signalling for technology licensing: a comparison

This article studies, in an adverse selection set‐up, how a patentee licenses a new technology in a two‐period context where the licensee has private information on its marginal cost of production. Two different ways of licensing are considered: the patentee offers, in the first period, either a menu of contracts that screens the different types of licensee or a single contract that obliges the licensee to signal its true type. Of these two contracts, the better for the patentee depends on the probability of the innovation gives rise to a low marginal cost and the difference between the high and low cost. Findings explain, to some degree, the variety of licensing contracts observed in practice (some including only a fixed fee, and others including both a royalty and a fixed fee). This variety may be rationalised by the use of different devices (signalling or screening) aimed at alleviating the effects of opportunism. A welfare comparison of the two means for extracting hidden information from the licensee is also made.
