In online commerce, a buyer cannot directly examine the product and has to rely heavily on the reliability of the seller. In this setting, the reputation of the seller, together with any other information signals on the quality of the product, can play an important role in determining the...

Consider a two-product firm that decides on the quality of each product. Product quality is unknown to consumers. If the firm sells both products under the same brand name, consumers adjust their beliefs about quality subject to the performance of both products. We show that if the probability...

A standard “solution” offered to the deleterious effects of all-out price competition is for firms to engage in differentiation strategies. This solution, however, depends critically on the inability of rivals to imitate a successful differentiation strategy. With imitation, we show how...

This paper offers a systematic exploration of reputation mechanism design in trading environments with opportunistic sellers, imperfect monitoring of a seller's actions and two possible seller effort levels, one of which has no value to buyers. The objective of reputation mechanisms in such...

This paper analyzes a mechanism through which a supplier of unknown quality can overcome its asymmetric information problem by selling via a reputable downstream rm. The supplier s adverse-selection problem can be solved if the downstream rm has established a reputation for delivering high...

In this paper, I study markets where consumers are heterogeneous with respect to both their concerns for the quality of goods and the image associated with them. Consumers with a taste for quality lend a positive image to the product of their choice and thereby increase the product's value to...

Consumption patterns can be indicative of how a consumer wants to be perceived by others. In this paper, I study markets where consumers are heterogeneous with respect to both their concerns for the quality of goods and the image associated with buying them. Consumers with a taste for quality...

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...
