Network cohesion

Cavalcanti, Tiago ; Giannitsarou, Chrysi ; Johnson, CR (2017)

This is the final version of the article. It first appeared from Springer via We define a measure of network cohesion and show how it arises naturally in a broad class of dynamic models of endogenous perpetual growth with network externalities. Via a standard growth model, we show why network cohesion is crucial for conditional convergence and explain that as cohesion increases, convergence is faster. We prove properties of network cohesion and define a network aggregator that preserves network cohesion.
