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 …

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 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 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 …

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 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...

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 …

The Colonel Blotto game is a two-player constant-sum game in which each player simultaneously distributes her fixed level of resources across a set of contests. In the traditional formulation of the Colonel Blotto game, the players' resources are quot;use it or lose itquot; in the sense that any...
