We modify the paper of Stahl (1989) [Stahl, D.O., 1989. Oligopolistic pricing with sequential consumer search. American Economic Review 79, 700–12] by relaxing the assumption that consumers obtain the first price quotation for free. When all price quotations are costly to obtain, the unique...

We examine an export game where two firms (home and foreign), located in two differentcountries, produce vertically differentiated products. The foreign firm is the most efficientin terms of R&D costs of quality development and the foreign country is relatively larger andendowed with a...

We generalize the model of Burdett and Judd (1983) to the case where an arbitrary finite number of firms sells a homogeneous good to buyers who have heterogeneous search costs. We show that a price dispersed symmetric Nash equilibrium always exists. Numerical results show that the behavior of...

This paper studies the estimation of the cost of non-sequential search. We provide a new method based on semi-nonparametric (SNP) estimation that allows us to pool price data from different consumer markets with the same underlying search cost distribution but dierent valuations or selling...

We study the role of search cost heterogeneity in four models of consumer search. The models cover markets for homogeneous and differentiated goods where consumers search non-sequentially and sequentially. When search costs are sufficiently dispersed, an increase in search costs (in the sense of...
