R&D Network Formation with Myopic and Farsighted Firms
We analyze the formation of bilateral R&D collaborations in an oligopoly when each
?rm bene?ts from the research done by other ?rms it is connected to. Firms can be either
myopic or farsighted when deciding about the links they want to form. Which R&D
networks are likely to emerge with farsighted or myopic ?rms? Which ?rms are more
likely to occupy key positions in the R&D network? What is the relationship between the
stable R&D network structures and the social welfare? We propose the notion of myopic-
farsighted stable set to determine the R&D networks that emerge when some agents are
myopic while others are farsighted. A myopic-farsighted stable set is the set of networks
satisfying internal and external stability with respect to the notion of myopic-farsighted
improving path. Stable R&D networks consist of two components where the larger group
of ?rms derive from their R&D collaborations a greater competitive advantage relative to
the other group. If there is a majority of myopic ?rms, they form two components of nearly
equal size. However, if more than half of the ?rms are farsighted, the largest component
comprises roughly three-quarters of ?rms, with farsighted ?rms having in average a higher
degree and betweenness centrality than myopic ?rms. However, some myopic ?rms may
have a high (if not the highest) betweenness centrality. Thus, even if myopic ?rms are
less active in terms of R&D collaborations they may play a crucial role for spreading the
innovation within the component. Suppose now that, in addition of myopic and farsighted
private ?rms, some ?rms are public ones. We show that (myopic or farsighted) public
?rms can help to stabilize some e¢ cient R&D networks by occupying key positions in
the networks. Finally, we study the dynamics of R&D networks starting from an initial
state where all ?rms are myopic, and where at each subsequent period some myopic ?rms
become farsighted.
