The theory of long waves is exceptionally fortunate in that, while there is no general consensus that they exist or, assuming that they do, what an appropriate theory should be, due to the unstinting efforts of several researchers, we have encyclopaedic compendia of the literature (Freeman 1996,...

This paper presents a qualitative study on the adoption of early information technologies, such as typewriters, calculators or Hollerith machines in US manufacturing in the period between 1870 and 1930, which was by all means a true systemic innovation. Our empirical work is guided by a...

One consequence of the internationalisation of R&D, particularly in high-tech sectors such as chemicals and pharmaceuticals, may be the transfer of foreign technology from the multinational to other firms in its home country. This phenomenon, which may be termed inter-firm reverse technology...
