An experimental study on information sharing networks

We design an experiment to study how agents make use of different pieces of information in the lab, depending on how many others have access to them and the strategic nature of interaction. Agents receive signals about a payoff relevant parameter, and the information structure is represented by a non directed network, whose nodes are agents and whose links represent sharing agreements. We compare the use of information in different information sharing networks, considering games in which strategies are substitute, complement and orthogonal. We then study the incentives to share information across games by analyzing the scenario where subjects have the chance to modify the network prior to playing the game.
