Past innovation network structures are calculated using citation patterns across technology classes during 1975 …-1994. The interaction of this pre-existing network structure with patent growth in upstream technology fields has strong …

This paper studies structural change in production networks for intermediate inputs (input-output network) and new … capital (investment network). For each network, we document a declining fraction of production by goods sectors and a rising … stemming from reallocation induced by structural change. At the same time, productivity growth within the input-output network …

We offer a new approach for measuring the … innovation network using patent data from Britain and France in the late-18th and early-19th century. We show that the network … innovation network, and the location of British inventors within it, explains an important share of the more rapid technological …
