This paper analyzes cheap talk in an investment model with information externalities. In contrast to Gossner and Melissas (2006), I allow for (i) competition effects, (ii) positive network externalities and (iii) more than one interviewed player. In the presence of competition effects, a player...

We introduce cheap talk in a dynamic investment model with information externalities. We first show how social learning adversely affects the credibility of cheap talk messages. Next, we show how an informational cascade makes truthtelling incentive compatible. A separating equilibrium only...

We study observational learning among agents with coordination motives. On a discrete time line, communities of agents receive private information about an uncertain state, observe some predecessors' actions, and then take their own action. An agent's payoff is both state-dependent and...

In this paper, I look at the interaction between social learning and cooperative behavior. I model this using a social dilemma game with publicly observed sequential actions and asymmetric information about payoffs. I find that some informed agents in this model act, individually and without...

This paper develops an identification strategy to generate unbiased estimates of Internet usage spillovers using a unique data set of US households. I identify multiple potential sources of learning including those from the household's locality, from educational Internet subsidies, and from...

This paper provides evidence for informational spillovers within urban slums in Chandigarh, India. I identify three groups, a treatment group, a neighboring spillover group, and a non-adjacent pure control group. Mothers of children (aged 3-6 years) enrolled in government day-care centers are...

Mere observation of others' choices can be informative about product quality. This paper develops an individual-level dynamic model of observational learning, and applies it to a novel data set from the U.S. kidney market where transplant candidates on a waiting list sequentially decide whether...
