The paper studies a model of delegated search. The distribution of search revenues is unknown to the principal and has to be elicited from the agent in order to design the optimal search policy. At the same time, the search process is unobservable, requiring search to be self-enforcing. The two...

We consider a cheap-talk setting that mimics the situation where an incumbent firm the sender is endowed with incentives to understate the true size of the market demand to two potential entrants the receivers. Although our experimental data reveals that senders messages convey truthful...

We consider a class of two-player quadratic games under incomplete information to study the relation between exogenous coordination motives and strategic interactions in information acquisition. The players make decisions in two stages. They decide about information acquisition in the first...

In this paper we study market environments where information is costly to acquire and is also useful to potential competitors. Agents may sell, or buy, reports over the information acquired and choose their trades in the market on the basis of what they learnt. Reports are unverifiable – cheap...

Several experimental studies show that ex post communication mitigates opportunistic behavior in social dilemmas. The source of this effect, especially in a repeated interaction, is nonetheless still obscure. This study provides a novel empirical testbed for two channels by which ex post...

We develop a model of information exchange through communication and investigate its implications for information aggregation in large societies. An \textit{underlying state} determines payoffs from different actions. Agents decide which others to form a costly \textit{communication link} with,...

This paper introduces a dynamic Bayesian game with an unknown population distribution. Players do not know the true population distribution and assess it based on their private observations using Bayes' rule. First, we show the existence and characterization of an equilibrium in which each...

Using a group identity manipulation we examine the role of social preferences in an experimental one-shot centipede game. Contrary to what social preference theory would predict, we fnd that players continue longer when playing with outgroup members. The explanation we provide for this result...

We study investment and consumption decisions in a dynamic game under learning. To that end, we present a model in which agents not only extract a resource for consumption, but also invest in technology to improve the future stock. At the same time, the agents learn about the stochastic process...

This paper investigates the possibility that people discover effective heuristics when playing similar perfect information games of varying complexity. We call this discovery experience Eureka Learning. We use a change-point analysis to identify 35 percent of our subjects as Eureka Learners.
