I develop a knowledge production function where new ideas are built from combinations of pre- existing elements.

Intellectual property rights are legal constraints that limit entry in industries where incumbents are innovators. The set of legal constraints is the same for all industries, without considering that the externalities created by entry are not necessarily negative for the incumbent or that the...

Basic innovations are often fundamental to the development of applications that may be developed by other innovators. In this setting, we investigate whether patent pools can rectify the lack of incentives for developers to invest in applications. Following Green and Scotchmer (1995), we also...
