Search engines enable advertisers to target consumers based on the query they have entered. In a framework in which consumers search sequentially after having entered a query, I show that targeting reduces search costs, improves matches and intensifies price competition. However, a...

This paper applies the theory of memory for advertising, developed in the consumer behavior literature, to an industrial organization setting to provide insight into advertising strategies in imperfectly competitive markets. There are two firms and infinitely many identical consumers. The firms...

We consider product markets in which consumers are interested only in a specific product category and initially do not know which product category matches their tastes. Using sophisticated tracking technologies, an intermediary can make inferences about a consumer's preferred product category...

To provide a more exible workhorse model of temporary price reductions or "sales", this paper presents a substantially generalized "clearinghouse" sales framework. Our framework permits multiple dimensions of firm heterogeneity, and views firms as competing directly in utility rather than...

How does advertising influence consumer decisions and market outcomes? We utilize detailed data on consumer shopping behavior and choices over bank accounts to investigate the effects of advertising on the different stages of the shopping process: awareness, consideration, and choice. We...

We examine the implications of limited consumer attention for the targeting decisions of competing firms. Limited attention alters the strategic role of information provision as firms may become incentivized to behave as mass advertisers, despite perfect targeting abilities. We analyze the...

We develop an advertising strategy for durable goods firms applying a dual time-period model while considering three-stage game in a Cournot competition. We assume that firms employ two advertising approaches; one is online advertising, which escalates consumers' willingness to purchase goods...

We extend the theory of tax incidence under Cournot-Nash oligopolistic competition to study the effects of an ad valorem sales tax on Web services (so-called Web Tax) that are provided free of charge to users, and produce advertising space sold to businesses. Ads are more valuable to advertisers...

We analyze markets where firms competing on price advertise to increase the probability of entering consumers' consideration sets. We find that moderately costly advertising allows firms to raise prices and possibly profits by reducing the fraction of price-conscious consumers, and by segmenting...

Internet users often surf to multiple websites in order to accomplish a single task. When this happens, do these different sites face the right incentives when choosing their advertising policies? We build a model showing that websites are prone both to over-advertise and to misallocate ads...
