Workhorse economic models used for studying the market impacts of search frictions assume constant search costs: individuals pay the same cost to obtain price information each time they search. This paper provides evidence on a new form of search costs: startup costs. Exploiting a natural...

Competition and consumer search costs can lead to price dispersion in an oligopoly. IO research has long identified the existence of search costs and estimated their distribution and is now beginning to study which consumers sit where in the distribution. This paper argues for a view of consumer...

We examine the relationship between concentration and price dispersion using variation induced by a merger in the Canadian mortgage market. Since interest rates are determined through a search and negotiation process, consolidation eliminates a potential negotiation partner, weakening consumers...

This paper develops and estimates a search and bargaining model designed to measure the welfare loss associated with frictions in oligopoly markets with negotiated prices. We use the model to quantify the consumer surplus loss induced by the presence of search frictions in the Canadian mortgage...
