-theoretic model of attack and defense of a network in which the defender's objective is to maintain network connectivity and the … attacker's objective is to destroy a set of nodes that disconnects the network. The conflict at each node is modeled as a … which a single random [minimal] set of nodes that disconnects the network is attacked …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

We investigate the trade-off between the risk-sharing gains enjoyed by more interconnected firms and the costs resulting from an increased risk exposure. We find that when the shock distribution displays “fat” tails, extreme segmentation into small components is optimal, while minimal...

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 …

We study a model of network formation and start-up financing with endogenous entrepreneurial type distribution. A hub … firm admits members to its network based on signals about entrepreneurs’ types. Network membership is observable, which … allows lenders to offer different interest rates to network and stand-alone entrepreneurs. We show that a network outcome can …

We develop and estimate a model of student study time on a social network. The model is designed to exploit unique data …: own study time may depend on friend study time in a heterogeneous manner. Social network data allow us to embed study time …

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other … workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects … network clearing). We show that those frictions and the wage mechanism are in general not independent. Equilibria that exhibit …
