Image concerns and the provision of quality

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 others. A monopolist restricts the product portfolio and charges price premia to allocate image along with quality. Heterogeneity in image concerns thereby provides a rationale for pooling consumers with differing quality preferences. Although image is correlated with a product's quality in equilibrium, an increase in the value of image may decrease quality provision. In a competitive market, premium prices are unsustainable so that image-concerned consumers buy excessive quality instead. Monopoly may therefore yield higher welfare than competition. Policy options to remedy the efficiency losses are discussed.
