Why some product innovations are licensed and others are not?

Abstract

We study in a Stackelberg industry the licensing of a product that embodies an innovation (quality-improving product) whose owner may be the firm that plays as a leader or a follower in setting output in the the product market. We find that the innovation is transferred (and social welfare is reduced) if its owner is the market-leader firm. However, if the innovation is in the hands of the market-follower firm, it is not licensed, even though licensing would be welfare enhancing. Thus, subsidizing R&D with the mandatory licensing of the resulting innovation may be a socially desirable policy
