Payments and discounts incentivize participation in many transactions about which people know little, but can learn more --- payments for medical trial participation, signing bonuses for job applicants, or price rebates on consumer durables. Who opts into the transaction when given such...

This article estimates a model of optimal search where consumers learn the distribution of gasoline prices during their driving trips. Our estimation incorporates traffic information and leverages the ordered search environment to recover parameters of the search and learning process using only...

I study a monopolistic pricing problem in which the consumer performs product research to determine whether or not to purchase a good. The consumer receives a signal of quality via a Brownian motion process with a type-dependent drift. I fully characterize the consumer's optimal strategy; she...

This paper studies the optimal design of a platform to incentivize its users to collectively acquire costly information about the quality of a product (or a service). A constant flow of users arrive in sequential order. Each user observes information disclosed by the platform and may acquire a...

A Bayesian decision maker is choosing among two alternatives with uncertain payoffs and an outside option with known payoff. Before deciding which alternative to adopt, the decision maker can purchase sequentially multiple informative signals on each of the two alternatives. To maximize the...

I investigate the identification of social learning in online markets. In these markets, there is often a two-stage decision making process where a consumer first chooses whether or not to search a product and then chooses whether or not to buy it. Additionally, the social learning signals are...

Networks and the embedded relationships are critical determinants of how people communicate and form beliefs. The explosion of social media has significantly increased the scope and impact of social learning among consumers. This paper studies observational learning in networks of friends versus...

Learning models extend the traditional discrete choice framework by postulating that consumers have incomplete information about product attributes, and that they learn about these attributes over time. In this survey we describe the literature on learning models that has developed over the past...

A monopolist uses prices as an instrument to influence consumers' belief about the unknown quality of its product. Consumers observe prices and sales in earlier periods to learn about the product. Every period they decide whether to consume the product or to wait for a lower price in future. We...

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...
