Abstract

We analyze daily mortgage rates posted by online lenders at the price comparison site, Microsurf. While cost shocks occurred almost daily in our sample, quoted mortgage rates are surprisingly rigid: Only 16 percent of the posted rates represent changes. However, firms that adjusted rates in response to cost shocks did so quite rapidly; about 98 percent of a cost shock was passed through within two days of the cost shock. Duration analysis reveals that the observed rigidity in rates systematically depends on market structure: Online mortgage rates are 30 to 40 percent more durable in concentrated markets than in markets where there are many competitors. We also find that rates posted online tend to exhibit downward stickiness; rate adjustments in response to cost increases are about twice the corresponding adjustments for cost decreases.

Keywords: Mortgage rate, price adjustment, price rigidity, price dispersion
