We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge … industrial revolution, followed by decreasing relative inequality. Knowledge diffusion through a Small World network explains the … knowledge throughout the world explains a period of increasing world inequality after the take-off of the forerunners of the …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … generosity with a sequence of dictator games conducted in the field. We find that networks of different dimensions differ … substantially in density, clustering, and centrality. When relating generosity to networks we observe that social distance only …

Maintaining the security of critical infrastructure networks is vital for a modern economy. This paper examines a game …-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 …

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...

We study the formation of networks in environments where agents derive benefits from other agents directly linked to … networks with undirected links (e.g. epidemics, underground resistance organizations, trade networks) where we find that stable … networks are comprised of completely connected disjoint subnetworks. Then, we consider networks with directed links and we find …

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 …

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 …
