We introduce a simple two-stage game of endogenous network formation and information sharing for reasoning about the … then we study how the network design and the utility specifications affect welfare. Surprisingly, we find that in general … "babblers" or "friends", irrespective of whether the network is unilateral or bilateral, in equilibrium, targeted information …

The Lightning Network is a decentralized payment network built on top of a block-chain, in which intermediary nodes … provide a trust-less routing service for end users. We provide an overview of the current state of the network and show that … strategically on the network. Those strategic interactions between nodes can be described by a Bertrand competition model with …

In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors … in the network benefit from each other's action levels through local complementarities and there exists a global …

This paper proposes a tractable model that allows us to analyze how agents' perception of relationships with others determines the structures of networks. In our model, agents are endowed with their own multidimensional characteristics and their payoffs depend on the social distance between...
