12 Apr 2013 | | Abstract: | Drawing on a large database of publicly announced R&D alliances, we track the
evolution of R&D networks in a large number of economic sectors over a long
time period (1986-2009). Our main goal is to evaluate temporal and sectoral
robustness of the main statistical properties of empirical R&D networks. By
studying a large set of indicators, we provide a more complete description of
these networks with respect to the existing literature. We find that most
network properties are invariant across pooled and sectoral networks. This
result suggests the presence of universal laws governing the dynamics of R&D
networks. Moreover, we find that many properties of R&D networks are
characterized by a non-monotonic trend with a peak in the mid-nineties. This
allows us to define the mid-nineties as a "Golden Age" characterized by the
rise-and-fall of R&D networks. Finally, we show that many properties of
empirical R&D networks support predictions of the recent theoretical literature
on R&D network formation. | | Source: | arXiv, 1304.3623 | | Services: | Forum | Review | PDF | Favorites | |
