“…The role of licensing in reference to innovative activity has been studied in-depth since 1980s and early 1990s: Shapiro (1985, 1986), Gallini (1984), Gallini and Winter (1985), Kamien and Tauman (1986), Kamien, Oren and Tauman (1992). They show the limits of voluntary licensing, compare the incentives to innovate in the presence and absence of licensing, consider the results for social welfare, compare different forms of compensation for licensing (fixed fee, royalty or auctions for licenses) and different forms of oligopolistic relationships (such as Cournot, Bertrand, and Stackelberg) Our agenda is very close to this but we focus on compulsory licensing as an element of competition (or pro-competition) policy and do not choose between different modes of oligopolistic relationships and different forms of compensation presuming the existence of a fixed-fee system, and modelling the interactions between players a la Cournot.…”
