We analyze an equilibrium search model in a duopoly setting with bilateral heterogeneities in production and search … in such a setting, compare the market advertising level to the socially optimal level, and find conditions in which firms …

We investigate the impact of consumer search and competition on pricing strategies in Germany's electricity retail. We … utilize a unique panel dataset on spatially varying search requests at major online price comparison websites to construct a … direct measure of search intensity and combine this information with zip code level data on electricity tariffs between 2011 …

For search costs that are not excessively high, in equilibrium the expert … mistakenly leave the expert, and some low-severity consumers incur unnecessary search costs.

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 profits due to their larger market shares. …

We develop an equilibrium sequential search model which includes most of the literature as special cases. In particular …, the model can accommodate heterogeneity in buyers’ search costs and demand functions and firms’ cost functions, with … equilibrium search models.

Firms simultaneously set prices in a homogeneous-product market where uninformed consumers search for price information ….
