Abstract
We design an experiment to study how agents make use of information in networks. Agents receive payoff-relevant signals automatically shared with neighbors. We compare the use of information in different network structures, considering games in which strategies are substitute, complement and orthogonal. To study the incentives to share information across games, we also allow subjects to modify the network before playing the game. We find behavioral deviations from the theoretical prediction in the use of information, which depend on the network structure, the position in the network and the strategic nature of the game. There is also a bias toward oversharing information, which is related to risk aversion and the position in the network.
