We evaluate the effect of the Federal Reserve's purchase of long-term Treasuries and other long-term bonds ("QE1" in 2008-2009 and "QE2" in 2010-2011) on interest rates. Using an event-study methodology we reach two main conclusions. First, it is inappropriate to focus only on Treasury rates as...

I study monetary and fiscal policy in liquidity trap scenarios, where the zero bound on the nominal interest rate is binding. I work with a continuous-time version of the standard New Keynesian model. Without commitment, the economy suffers from deflation and depressed output. I show that,...

We characterize monetary and fiscal policy rules to implement optimal responses to a substantial decline in the natural rate of interest, and compare them with policy decisions made by the Japanese central bank and government in 1999-2004. First, we find that the Bank of Japan's policy...

This paper has three parts. Part 1 constructs a classical economic model of inflation, augmented by a complete set of financial markets; I call this the core monetary model. Part 2 develops a series of calibrated examples to illustrate how the core monetary model explains the history of...

The standard workhorse models of monetary policy now commonly in use, both for teaching macroeconomics to students and for supporting policymaking within many central banks, are incapable of incorporating the most widely accepted accounts of how the 2007-9 financial crisis occurred and incapable...

This paper develops an affine model of the term structure of interest rates in which bond yields are driven by observable and unobservable macroeconomic factors. It imposes restrictions to identify the effects of monetary policy and other structural disturbances on output, inflation, and...

We estimate the effect of shifts in monetary policy using the term structure of interest rates. In our no-arbitrage model, the short rate follows a version of the Taylor (1993) rule where the coefficients on the output gap and inflation vary over time. The monetary policy loading on the output...

We consider the desirability of modifying a standard Taylor rule for a central bank's interest-rate policy to incorporate either an adjustment for changes in interest-rate spreads (as proposed by Taylor [2008] and by McCulley and Toloui [2008]) or a response to variations in the aggregate volume...

We first document a large secular shift in the estimated response of the entire term structure of interest rates to inflation and output in the United States. The shift occurred in the early 1980s. We then derive an equation that links these responses to the coefficients of the central bank's...

This paper shows that the theory of monetary policy rules is able to explain, predict, and help understand a variety of phenomenon in macroeconomics and finance, including the Great Moderation, the correlation between exchange rates and interest rates, and the shift in the response of the term...
