The appropriate role for equity prices in monetary policy deliberations has been hotly debated for some time. Recent work suggests that equity prices have affected monetary policy decisions above and beyond their indirect effect on the traditional goal variables of the FOMC. However, the correlation between stock price movements and these other goal variables has made the identification of the equity price effect problematic.

The authors show that, in fact, the methods used in the earlier literature fail to adequately disentangle the observational equivalence problem. The authors then show that after controlling for the information that actually enters the FOMC's decision-making process, equity prices have had no independent effect on monetary policy
