This paper studies a model in which some consumers shop on the basis of price alone, without attention to potential differences in product quality. A firm may offer a low-quality product to exploit these inattentive consumers. In the unique symmetric equilibrium of the model, firms choose prices...

This paper investigates discount pricing, the common marketing practice whereby a price is listed as a discount from an earlier, or regular, price.  We discuss two reasons why a discounted price - as opposed to a mearly low price - can make a rational consumer more willing to purchase the...

Firms simultaneously set prices in a homogeneous-product market where uninformed consumers search for price information. Some uninformed consumers are local searchers who visit only one seller, possibly due to high search costs or bounded rationality; whereas others search sequentially with an...

We use data from restaurants in Shanghai, China to conduct a new empirical analysis of prices and coupons. Our results show a positive relationship between prices and online coupons. Moreover, the price premium from couponing is higher for restaurants about which consumer values appear to be...

Low-quality products may cause consumer harm. A firm can reduce the probability of low quality through ex ante investment before sales, and can take remedy actions such as product recalls if it learns after sales that product quality is low. An increase in the firm's product liability increases...

A vertically integrated firm, having acquired the intellectual property (IP) through innovation to become an input monopolist, can extract surplus by supplying efficient downstream competitors. That the monopolist would refuse to do so is puzzling and has led to numerous debates in antitrust. In...

The effects of entry on consumer and total welfare are studied in a model of consumer search. Potential entrants differ in quality, with high-quality sellers being more likely to meet consumer needs. Contrary to the standard view in economics that more entry benefits consumers, we find that...

Retrospective studies of horizontal mergers have focused on their price effects, leaving the important question of how mergers affect product quality largely unanswered. This paper empirically investigates this issue for two recent airline mergers: Delta/Northwest and Continental/United....
