Lagged interest rates crucial in predicting Federal Reserve's actions.
The study looked at how the Federal Reserve sets interest rates using Taylor rules, focusing on interest rate smoothing. By analyzing different models, the researchers found that the lagged interest rate plays a significant role in determining the federal funds rate path. This suggests that past interest rates influence current decisions, along with other factors like preferences on the output gap and financial market indicators. While policy shocks may also impact interest rates, the study highlights the importance of considering the lagged interest rate in Taylor-type models.
