facilities, since LIBOR-OIS spreads faced structural change in August, 2007 and changed again when
Bear Stearns was rescued in March, 2008. The results of this study indicate that the Term Auction Facility
helped to relieve strains in money markets in early 2008 but that the benefits of the program largely
disappeared as financial stress moved from commercial to investment banks. The results also indicate
that the TSLF and PDCF were unable to significantly lower borrowing rates in money markets. The
methodological approach faced various limitations, particularly the lack of control variables accounting
for credit risk and the potential endogeneity problem regarding the announcement and expansion of
Federal Reserve programs. The paper also identifies the difficulties associated with estimating structural
models relating to financial variables, since model parameters are subject to change as the conditions and
concerns facing market participants evolve. Nevertheless, much about the relative effectiveness of
Federal Reserve programs can be observed through the simple OLS framework advanced in this paper.
