This paper examines the impact of bank consolidation on mortgage rates. Mortgage markets are decentralized and so rates are determined through a search and negotiation process. The primary effect of consolidation is therefore to reduce the number of partners with whom to negotiate. Using a Canadian merger as a case study, we find that, on aggregate, margins increased 9% relative to the average, but also that there is important heterogeneity in the impact of the merger: consumers able to negotiate sizeable discounts were adversely affected, while consumers at the top of the conditional price distribution were not. Overall, the merger decreased price dispersion.
