Discount window borrowing by weekly reporting banks disaggregated by Federal Reserve District is used to estimate Goodfriend's model of borrowed reserves. Little evidence is found to support the argument that a bank's borrowing decision is determined by the spread between the funds rate and the discount rate and by prior bank borrowing. A weekly reporting bank has only a 2.7% chance of visiting the discount window during any given maintenance period. This result is consistent with the presence of considerable harassment costs imposed by the discount window officer.
