Some key structural features of the U.S. economy appear to have changed in the recent decades, making the conduct of monetary policy more challenging. In particular, there is high uncertainty about the levels of the natural rate of interest and unemployment as well as about the effect of...

Over the past few years, the Federal Reserve's use of unconventional monetary policy tools has led it to hold a large portfolio of securities. The securities holdings in excess of historical norms have been shown to be putting downward pressure on longer-term interest rates. One question asked...

This paper applies natural language processing to a large corpus of central bank speeches to identify those related to climate change. We analyze these speeches to better understand how central banks communicate about climate change. By all accounts, communication about climate change has...

We examine the implications of less powerful forward guidance for optimal policy using a sticky-price model with an effective lower bound (ELB) on nominal interest rates as well as a discounted Euler equation and Phillips curve. When the private-sector agents discount future economic conditions...

In low-rate environments, policy strategies that involve holding rates "lower for longer" (L4L) may mitigate the effects of the effective lower bound (ELB). However, these strategies work in part by managing the public's expectations, which is not always realistic. Using the Fed's large-scale...

This paper updates the standard workhorse model of banks' reserve management to include frictions inherent to money markets. We apply the model to study monetary policy implementation through an operating regime involving voluntary reserve targets (VRT). When reserves are abundant, as is the...

Methods of monetary policy implementation continue to change. The level of reserve supply -- scarce, abundant, or somewhere in between -- has implications for the efficiency and effectiveness of an implementation regime. The money market events of September 2019 highlight the need for an...

Large-scale asset purchases by the Federal Reserve as well as new Basel III banking regulations have led to important changes in U.S. money markets. Most notably the interbank market has essentially disappeared with the dramatic increase in excess reserves held by banks. We build a model in the...

As a result of legal restrictions on branch banking, an extensive interbank system developed in the United States during the 19th century to facilitate interregional payments and flows of liquidity and credit. Vast sums moved through the interbank system to meet seasonal and other demands, but...

We study optimal long-run capital taxation in a closed economy with heterogeneity in agents' time-discount factors where borrowing is allowed but restricted by a collateral constraint. Financial frictions distort intertemporal optimization margins and the tax system serves a dual role: first, it...
