This paper is the first to estimate the impact of exposure to deceptive advertising on consumption of the advertised product and its substitutes. We study the market for over-the-counter (OTC) weight-loss products, a market in which deceptive advertising is rampant and products are generally...

In a field experiment in Uganda, we find that demand after a free distribution of three health products is lower than after a sale distribution. This contrasts with work on insecticide-treated bed nets, highlighting the importance of product characteristics in determining pricing policy. We put...

This paper investigates consumer switching costs in the context of health insurance markets, where adverse selection is a potential concern. Though previous work has studied these phenomena in isolation, they interact in a way that directly impacts market outcomes and consumer welfare. Our...

We present a model of coarse thinking, in which individuals group situations into categories, and transfer the informational content of a given message from situations in a category where it is useful to those where it is not. The model explains how uninformative messages can be persuasive,...

We study the impact of competition on information revelation in a class of Bayesian Persuasion games with multiple senders. Senders with no private information choose what information to gather and communicate to a receiver who takes a non-contractible action that affects the welfare of all...

When is it possible for one person to persuade another to change her action? We take a mechanism design approach to this question. Taking preferences and initial beliefs as given, we introduce the notion of a persuasion mechanism: a game between Sender and Receiver defined by an information...

We formally model direct to consumer advertising (DTCA) of prescription drugs and examine factors that determine a pharmaceutical firm's DTCA strategy. We highlight how the profitability of DTCA varies with the characteristics of the condition that the advertised drug treats, the incidence of...

Our understanding of the determinants of physician skill and the extent to which skill is valued in the marketplace is superficial. Using a large, detailed panel of new obstetricians, we find that, even though physicians' maternal complication rates improve steadily with years of practice,...

We estimate a Bayesian learning model in order to assess the value of health plan performance information and the extent to which the explicit provision of information about product quality alters consumer behavior. We take advantage of a natural experiment in which health plan performance...

Small-area-variation studies have shown that physician treatment styles differ substantially both between and within markets, controlling for patient characteristics. Using a data set containing the universe of deliveries in Florida over a 12-year period with consistent physician identifiers and...
