This paper studies network games with strategic complementarities when agents have only partial knowledge of, but some control over, how their actions are mapped into payoff-relevant outcomes. Uncertainty changes several predictions of standard network models. Equilibrium actions are positively...

Open innovation is the practice of combining internal R&D efforts with external sources of knowledge. While project developers allocate effort between internal development and external knowledge processing, knowledge brokers search for relevant external ideas. When external knowledge is...

We design a novel experiment to study how subjects update their beliefs about the beliefs of others. Three players receive sequential signals about an unknown state of the world. Player 1 reports her beliefs about the state; Player 2 simultaneously reports her beliefs about the beliefs of Player...

We analyze social learning and innovation in an overlapping generations model in which available technologies have correlated payoffs. Each generation experiments within a set of policies whose payoffs are initially unknown and drawn from the path of a Brownian motion with drift. Marginal...

We study the effectiveness of social learning when subjects can also learn individually. In the baseline treatment, a subject observes a sequence of private signals about an unknown state of the world and chooses an action to match the state. In the unilateral social learning treatment, a...
