We consider a strategic online social network that controls information flows between agents in a social learning setting. Agents on the network select among products of competing firms of unknown quality. The network sells advertising to firms. We consider display advertising, which is standard...

This paper considers a dynamic market with a strategic, price setting firm that knows the quality of the product it sells to an infinite set of rational consumers who enter the market sequentially and observe conditionally independent private signals about the quality. In equilibrium, the price...

This paper introduces a novel robustness concept for generic sets in function spaces. As motivation, I provide an economically relevant example of a functional property, where a subset of the domain with arbitrary small (Lebesgue) measure marks the difference between the functional property...

This paper investigates the robustness of three of the core insights of the DeGroot model of boundedly rational updating in social networks. Two updating systems are ε-close if their supremum norm distance is equal to ε. An ε-perturbation of a DeGroot (weighted average) updating system is any...

This paper introduces a model of boundedly rational observational learning, which is rationally founded and applicable to general environments. Under Quasi-Bayesian updating each action is treated as if it were based only on the private information of its respective observed agent. We analyze...

We consider a dynamic market with two firms that sell competing common-value products. The firms offer both products to an infinite set of rational consumers. Each consumer observes a conditionally independent and identically distributed private signal about the product qualities. Consumers...

This paper considers a dynamic duopoly market with strategic, price setting firms and an infinite set of fully rational, privately informed consumers who enter the market sequentially. I show that there exists a sequential equilibrium in which prices converge to their realized product qualities...

This paper presents a non-Bayesian model of social learning in networks in an environment with a finite set of actions. We conduct a laboratory experiment in which participants play an urn-guessing game over several decision rounds while observing the previous choices of the network members to...

In online social networks, social information, i.e., content generated and shared by users (e.g., past purchases), can be a substitute for sponsored advertising, which constitutes the network's main source of revenue. When will social information be let to spread freely over the platform? We...
