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 …

Bad risks benefit from … having a connection with a good firm, but they are a cost to both direct and indirect connections. In efficient networks the … good risks should form large connected components with very few bad risks attached. The equilibrium networks, on the other …

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 …
