Because of the concentrated distribution of interest rates on outstanding mortgages, modest interest rate declines in 1997 and 1998 made refinancing a smart choice for a record number of homeowners. In addition, the strong economy and the age of mortgage loans likely contributed to the surge in...

Despite the enormous popularity of the market for repurchase agreements, the behavior of interest rates on "repo" transactions is not well understood. An analysis of new data for 1992-95 reveals that repo rates on recently issued Treasury notes rise and fall in a regular pattern as the Treasury...
