In the second half of the 20th century---spurred by findings that technological change played an important role in determining economic growth---research on innovation and Research and Development (RaD) became more common. The positive externalities, or spillovers, associated with RaD have been a source of much confusion and debate. The first chapter examines the history of this research, with an emphasis on the emergence of a new way of modeling RaD and spillovers, namely the construction of qpools of knowledge.qMuch of this complexity ultimately stems from a number of diAcerences between Raamp;D and other types of investments. ... the output capacity of the factory, but the costs of designing a new car does not depend on how many cars will be produced.
