We develop a new framework to study the implementation of monetary policy through the banking system. Banks finance illiquid loans by issuing deposits. Deposit transfers across banks must be settled using central bank reserves. Transfers are random and therefore create liquidity risk, which in...

The U.S. Federal Reserve used the Term Auction Facility (TAF) to provide term funding to eligible depository institutions from December 2007 to March 2010. According to the Fed, the purpose of TAF was to inject term funds through a broader range of counterparties and against a broader range of...

The cheapest way for banks to finance long term illiquid projects is typically to borrow short term from households. But when household needs for funds are high, interest rates will rise sharply, debtors will have to shut down illiquid projects, and in extremis, will face more damaging runs....

This article explains how debt markets have malfunctioned in the crisis, with deleterious consequences for the real economy. I begin with a quick overview of debt markets. I then discuss three areas that are crucial in all debt markets decisions: risk capital and risk aversion, repo financing...

The dangers of shouting "fire" in a crowded theater are well understood, but the dangers of rushing to the exit in the financial markets are more complex. Yet, the two events share several features, and I analyze why people crowd into theaters and trades, why they run, what determines the risk,...

The paper considers three methods for eliminating the zero lower bound on nominal interest rates and thus for restoring symmetry to domain over which the central bank can vary its policy rate. They are: (1) abolishing currency (which would also be a useful crime-fighting measure); (2) paying...

The global economy has a chronic shortage of safe assets which lies behind many recent macroeconomic imbalances. This paper provides a simple model of the Safe Asset Mechanism (SAM), its recessionary safety traps, and its policy antidotes. Safety traps share many common features with...

We build a macroeconomic model that centers on liquidity transformation in the financial sector. Intermediaries maximize liquidity creation by issuing securities that are money-like in normal times but become illiquid in a crash when collateral is scarce. We call this process shadow banking. A...

In the recent financial crisis, macroeconomic stimuli produced mixed results across developed economies. In contrast, China's stimulus boosted real GDP growth from an annualized 6.2% in the first quarter of 2009 trough to 11.9% in the first quarter of 2010. Amidst this phenomenal response, land...

This paper examines what we have learned and how we should change our thinking about monetary policy strategy in the aftermath of the 2007-2009 financial crisis. It starts with a discussion of where the science of monetary policy was before the crisis and how central banks viewed monetary policy...
