In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors … in the network benefit from each other's action levels through local complementarities and there exists a global …

both, the network of R&D collaborations as well as the market structure, are endogenously determined. We show that the … coevolution of market and network structure matter for the relationship between competition and innovation. Moreover, our model … allows us to explain differences in the R&D network structures observed across different industries, and how they are related …

a fully endogenous network formation model with monopolistically competitive firms, in which firms exit due to exogenous … shocks, or the propagation of shocks through the network. Firms can replace suppliers they have lost due to exit subject to … network, and we show that depending on the nature of the shocks, adaptivity can make the network more or less stable. …
