Researchers have made great strides in improving our understanding of the effects of unconventional monetary policy. Although further study is needed, the evidence from the past few years demonstrates that both forward guidance and large-scale asset purchases are useful policy tools when...

The zero lower bound on nominal interest rates began to constrain many central banks’ setting of short-term interest rates in late 2008 or early 2009. According to standard macroeconomic models, this should have greatly reduced the effectiveness of monetary policy and increased the efficacy of...

We examine the performance and robustness of monetary policy rules when the central bank and the public have imperfect knowledge of the economy and continuously update their estimates of model parameters. We find that versions of the Taylor rule calibrated to perform well under rational...

Using a short-term interest rate as the monetary policy instrument can be problematic near its zero bound constraint. An alternative strategy is to use a long-term interest rate as the policy instrument. We find when Taylor-type policy rules are used to set the long rate in a standard New...

The recent financial crisis saw a dramatic and persistent jump in interest rate spreads between overnight federal funds and longer-term interbank loans. The Fed took several actions to reduce these spreads, including the creation of the Term Auction Facility (TAF). The effectiveness of these...

Before the recent recession, the consensus among researchers was that the zero lower bound (ZLB) probably would not pose a significant problem for monetary policy as long as a central bank aimed for an inflation rate of about 2 percent; some have even argued that an appreciably lower target...

The zero lower bound on nominal interest rates has constrained the Federal Reserve’s setting of the overnight federal funds rate for over three years running. According to many macroeconomic models, such an extended period of being stuck at the zero bound has important implications for the...

An analysis shows that the Federal Reserve’s large-scale asset purchases have been effective at reducing the economic costs of the zero lower bound on interest rates. Model simulations indicate that, by 2012, the past and projected expansion of the Fed’s securities holdings since late 2008...
