Has the Internet changed the pattern of social relations? More specifically, have social relations undergone any systematic change during the recent widespread diffusion of new communications technology? This question is addressed using a unique longitudinal survey that bookends the entire period of Internet diffusion in two African nations and one Indian state. We analyze data on nine professional linkages reported by a population of agricultural and environmental scientists in Kenya, Ghana, and Kerala over a sixteen-year period. Factor analysis reveals two (...) clusters of relationships, one interpretable as traditional scientific exchange, the other indicating mediated forms of collaboration. While collaboration increases in frequency, friendship declines. We interpret this shift as a consequence of communications technology that facilitates formal projects, reducing the affective dimension of professional association. (shrink)

The conventional wisdom holds that U.S. political institutions are inhospitable to industrial policy. The authors call the conventional wisdom into question by making four claims: the activities targeted by industrial policy are increasingly governed by decentralized production networks rather than markets or hierarchies, “network failures” are therefore no less threatening to industrial dynamism than market or organizational failures, the spatial and organizational decentralization of production have simultaneously increased the demand and broadened the support for American industrial policy, and political decentralization (...) is therefore likely to improve the functioning of industrial policies designed to combat network failures.
