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 …

-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 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...

Interbank claims are a concern to regulators as they might facilitate the dissemination of defaults and generate spill-over effects. Building on a simple model, this paper introduces a measure of the spill-over effects that a bank generates when it defaults. The measure is based on an explicit...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest … sale externalities. The resulting network configurations exhibits a core-periphery structure, dis-assortative behavior and … low clustering coefficient. We measure systemic importance by means of network centrality and input-output metrics and the …

We study stable matchings on exogenously given or endogenously formed bipartite graphs that reflect constraints on matching. The effects of a change of the exogenously given graph (constraints) are investigated. Specifically, we examine to what extent individuals gain or lose from relaxing...

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 …
