In Internet transactions, customers and service providers often interact once and anonymously. To prevent deceptive behavior a reputation system is particularly important to reduce information asymmetries about the quality of the offered product or service. In this study we examine the...

This paper studies the relationship between three key elements of the marketing mix, namely, price, product, and promotion, in a model where a seller employs informative advertising to launch a new product. We propose a fairly general advertising technology for the study of three promotional...

This paper analyzes optimal product lines when consumers differ both in their taste for quality and in their desire for social image. The market outcome features partial pooling and product differentiation that is not driven by heterogeneous valuations for quality but by image concerns. A...

A long-lived seller sells a product by setting prices and making product recommendations to short-lived consumers arriving in continuous time. The seller receives consumer feedback about the product value, whose arrival rate depends on the instantaneous sales volume. Under a constant pricing...

We consider consumer entry in the canonical monopolistic nonlinear pricing model ( Mussa and Rosen 1978) wherein consumers learn their preference “types” after incurring privately known entry costs. We show that by taking into account consumer entry, the nature of optimal nonlinear pricing...

There is widespread evidence that some firms use false advertising to overstate the value of their products. Using a model in which a policymaker is able to punish such false claims, we characterize a natural equilibrium in which false advertising actively influences rational buyers. We analyze...

I study optimal information provision by a search goods seller. While the seller controls a consumer's pre-search information, which decides whether she will engage in costly search for the product, he cannot control her post-search information because the consumer would inevitably learn the...

Using a Markov-perfect equilibrium model, we show that the use of customer data to practice intertemporal price discrimination will improve monopoly profit if and only if information precision is higher than a certain threshold level. This U-shaped relationship lends support to a popular view...
