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 …

This paper studies a noncooperative model of network formation. Built upon the two-way flow model of Bala and Goyal …

Our study further reveals that when ignoring the network structure the impact of firm exit or mergers is significantly …

We analyze a model of endogenous two-sided network formation where players are affected by uncertainty in their … inefficient networks such as the empty network. On the other hand, it may include networks with unreciprocated, one-way links …

, we construct an information-network model incorporating both information transmitters and information aggregators. Given … network equilibrium, its optimality and the patterns of equilibrium and optimal configuration. We then allow for endogenous … costs, the monocentric network with one aggregator connecting to all other agents as transmitters on a tree graph is the …

We study the impact of bots on social learning in a social network setting. Regular agents receive independent noisy … signals about the true value of a variable and then communicate in a network. They na¨ıvely update beliefs by repeatedly … taking weighted averages of neighbors' opinions. Bots are agents in the network that spread fake news by disseminating biased …

We find that information supports cooperation by increasing trust between players, and obtain the … 'radius of trust': an endogenous network listing the potentially cooperative relationships between pairs of players in a … community. We identify two aspects of trust, which relate to the network structure in different ways. Where trust depends on the …

We investigate the network topology of a comprehensive data set of the world-wide population of corporate entities. In …
