We embed the principal-agent model in a model of spatial differentiation with correlated consumer preferences to investigate the competitive implications of personalized pricing and quality allocation (PPQ), whereby duopoly firms charge different prices and offer different qualities to different...

When firms' shrouding of charges, as in Gabaix and Laibson (2006), meets with consumers' salient thinking, as in Bordalo et al. (2013), this can have severe welfare implications. The ensuing excessive competition for headline prices tends to inefficiently bias consumers' choice towards...

We analyze a sample of consumer-electronics products sold by the US NewEgg online-retailer to study the impact of Price Matching Guarantees (PMGs) policies on prices. By applying aDifference-in-Differences approach,we find that prices of the policy-adopting retailer increase by 4.7% during the...

We consider a market in which some consumers are fully informed about the quality of a product sold by different firms, while other consumers are uninformed. We examine the effects on the prices and qualities offered in the market of increasing the fraction of informed consumers. In equilibrium,...

To make sense of mixed empirical evidence on the pricing rigidity of cartels, this paper studies how colluding firms price their goods in a model where firms have private marginal costs and sell to consumers with search costs. In this model, firms repeatedly interact in selling a homogeneous...

In standard macroeconomic models, the costs of inflation are tightly linked to the price dispersion of identical goods. Therefore, understanding how price dispersion empirically relates to inflation is crucial for welfare analysis. In this paper, I study the relationship between steady-state...

This paper analyzes price competition in an infinitely repeated duopoly game. In each period, consumers remember the existence and location of their previous supplier. New information is gathered via search or word-of-mouth communication. Market outcomes are history-dependent, and the Markov...

This note presents an ordered search model in which consumers search both for price and product fitness. We construct an equilibrium in which there is price dispersion and prices rise in the order of search. The top firms in consumer search process, though charge lower prices, earn higher...

In this article, we provide a novel measure of product differentiation by observing consumer search behavior directly. We track individual consumers in a price search engine and generate a measure of distance in product space, based on goods surveyed conjointly within individual search episodes....
