The Stahl model is one of the most applied consumer search models, with many applications and an empirical background. The present paper explores an extension where sellers have asymmetries, which is mostly excluded by the literature. Sellers with heterogeneous numbers of stores are introduced,...

We investigate empirically how sellers react to changes in the population of their consumers, identifying the effects of demand composition and demand size with limited information on costs. We show how pharmacists in Italy selectively increase the price of some products when they observe in...

Consumers need not evaluate all available product information before making a purchase. This may arise because shopping environments prevent a full evaluation (e.g. online). We develop a model of simultaneous search in which consumers have limited ability in product evaluation in order to study...

Using a model of sequential search, we show that announcements to price-match raise prices by altering consumer search behavior. First, price-matching diminishes firms' incentives to lower prices to attract consumers who have no search costs. Second, for consumers with positive search costs,...

This note explores asymmetries in the way consumers sample prices in a simple variation of Stahl's (1989) seminal model of sequential search. In the note, we characterize a unique equilibrium in which a firm that caters to more local consumers selects prices from a distribution which first order...

We study price formation in the standard model of consumer search for differentiated products but allow for search cost heterogeneity. In doing so, we dispense with the usual assumption that all consumers search at least once in equilibrium. This allows us to analyze the manner in which prices...

This study constructs a consumer search model in which some consumers search for multiple products, whereas others search for a single product. A price difference arises because of a difference in the price elasticity for each group. We show that a positive demand shock to one of the products...

I analyse a homogeneous goods framework where firms receive binary and noisy signals about consumer valuations and consumers engage in sequential search. Firms have no information about consumers' search histories in the baseline model. Different search costs give rise to structurally different...
