particular, if the linking costs are not too low and not too high, at least one such network is pairwise stable. Moreover, in … explanation for many core-periphery structures observed in real life social networks. -- Network Formation ; Heterogeneity …

We construct an empirical measure of expected network spillovers that arise through default cascades for the U …

We develop a strategic model of network interdiction in a non-cooperative game of flow. An adversary, endowed with a … bounded quantity of bads, chooses a flow specifying a plan for carrying bads through a network from a base to a target …. Simultaneously, an agency chooses a blockage specifying a plan for blocking the transport of bads through arcs in the network. The …
