Revamping the Kansas City Financial Stress Index Using the Treasury Repo Rate

The Kansas City Financial Stress Index (KCFSI) uses the London Interbank Offered Rate (LIBOR) to measure money market borrowing conditions. But regulatory changes in the United Kingdom will eliminate LIBOR by 2021. We construct a revised financial stress index with a variable that measures the cost of borrowing collateralized by Treasury securities (the Treasury repo rate) instead of LIBOR. {{p}} This revised measure of the KCFSI is highly correlated with the current KCFSI, suggesting the Treasury repo rate can replace LIBOR.

The state space representation and estimation of a time-varying parameter VAR with stochastic volatility

To capture the evolving relationship between multiple economic variables, time variation in either coefficients or volatility is often incorporated into vector autoregressions (VARs). However, allowing time variation in coefficients or volatility without restrictions on their dynamic behavior can increase the number of parameters too much, making the estimation of such a model practically infeasible. For this reason, researchers typically assume that time-varying coefficients or volatility are not directly observed but follow random processes which can be characterized by a few parameters. ...

A Bayesian evaluation of alternative models of trend inflation

The concept of trend inflation is important in making accurate inflation forecasts. However, there is little consensus on how the trend in inflation should be modeled. While some studies suggest a survey-based measure of long-run inflation expectations as a good empirical proxy for trend inflation, others have argued for a statistical exercise of decomposing inflation data into trend and cycle components. In this paper, we assess alternative models of trend inflation based on the accuracy of medium-term inflation forecasts. To incorporate recent evidence on the time-varying macroeconomic ...

Yield curve in an estimated nonlinear macro model

What moves the yield curve? This paper specifies and estimates a dynamic stochastic general equilibrium (DSGE) model solved using a second order approximation to equilibrium conditions to answer this question. From the empirical analysis of U.S. data from 1983:Q1 to 2007:Q4, I find that the monetary policy response to the inflation gap defined by the difference between expected inflation and the inflation target of the central bank is a key channel transmitting macro shocks to the yield curve and that the degree of nominal rigidity determines which macro shocks are more important determinants ...

Monetary policy regime shifts and inflation persistence

This paper reports the results of estimating a Markov-Switching New Keynesian (MSNK) model using Bayesian methods. The broadest and best fitting MSNK model is a four-regime model allowing independent changes in the regimes governing monetary policy and the volatility of the shocks. We use the estimates to investigate the mechanisms that lead to a decline in the persistence of inflation. We show that the population moment describing the serial correlation of inflation is a weighted average of the autocorrelation parameters of the exogenous shocks. Changes in the monetary or shock volatility ...

Long run risks in the term structure of interest rates: estimation

This paper specifies and estimates a long run risks model with inflation by using the nominal term structure data in the United States from 1953 to 2006. The negative correlation between expected inflation and expected consumption growth in conjunction with the Epstein-Zin (1989) recursive preferences generates an upward sloping yield curve and fits the yield curve data better than the alternative specifications. However, the variations of the forward looking components of consumption growth and inflation in the estimated model are much smaller than implied by calibrated parameter values in ...

What does the yield curve tell us about the Federal Reserve's implicit inflation target?

This paper studies the time variation of the Federal Reserve?s inflation target between 1960 and 2004 using both macro and yield curve data. I estimate a New Keynesian dynamic stochastic general equilibrium model in which the inflation target follows a random-walk process. I compare estimation results obtained from both macroeconomic and yield curve data, two estimates obtained with only macro data, in order to determine what the yield curve tells us about the inflation target. In the joint estimation, the estimated inflation target is much higher during the mid 1980s than in the ...

Measuring the Stance of Monetary Policy on and off the Zero Lower Bound

Taeyoung Doh and Jason Choi propose a new ?shadow? short-term interest rate to measure the stance of policy when the federal funds rate was constrained by the zero lower bound.

Has the effect of monetary policy announcements on asset prices changed?

The Federal Reserve increasingly has relied on forward guidance about the future path of the federal funds rate to implement monetary policy since the federal funds target rate reached its effective lower bound. The enhanced use of forward policy guidance has drawn attention to any change in its influence on the real economy. Changes in policy guidance affect the private sector?s expectations about the future path of the federal funds rate and, in turn, affect bond yields, stock prices and asset values. Changes in asset values influence real activity through their effects on spending by ...

Tracking U.S. GDP in Real Time

Measuring the current state of the U.S. economy in real time is an important but challenging task for monetary policymakers. The most comprehensive measure of the state of the economy?real gross domestic product?is available at a relatively low frequency (quarterly) and with a significant delay (one month). To obtain more timely assessments of the state of the economy, the Federal Reserve Bank of Kansas City has developed a GDP tracking model that combines new econometric methods with two conventional approaches to estimating GDP. {{p}} Taeyoung Doh and Jaeheung Bae review the Kansas City Fed ...
