Expectations, credibility, and disinflation in a small macroeconomic model
A study of the effects of expectations and central bank credibility on the economy's dynamic transition path during a disinflation. Using a version of the Fuhrer-Moore model, it compares simulations under different specifications that vary according to the way expectations are formed and the degree of central bank credibility.

Regime switching in the dynamic relationship between the federal funds rate and nonborrowed reserves
This paper examines the dynamic relationship between changes in the funds rate and nonborrowed reserves within a reduced form framework that allows the relationship to have two distinct patterns over time. A regime switching model a la Hamilton (1989) is estimated. The two regimes are different in such characteristics as average changes in the interest rate, and volatility. The historical aerate of the API inflation rate is significantly higher in the high growth and more volatile regime. Innovations in money growth are associated with a strong anticipated inflation effect in the high ...

Asymmetry in the bivariate relationship between output and interest rates
This paper investigates whether an asymmetry is present in the Granger-causal relationship between output and a set of interest rates and their spreads, across expansionary and contractionary business cycle phases in post 1950 U.S. Non-structural VAR models of monthly industrial production and three interest rates and four spreads are estimated for expansion and contraction samples. This study finds asymmetry in the bivariate relationship between the output and the financial variables across the two samples. Most of the interest rates and the spreads that were observed to Granger-cause output ...

Forecasting industrial production using models with business cycle asymmetry
This paper exploits business cycle asymmetry observed in data, namely, a systematic shift in the dynamic relationship between the output and the interest rate spread across expansionary and contractionary periods in forecasting monthly industrial production. A bivariate model of monthly industrial production and the spread between the 6-month commercial paper and the federal funds rates is used as an example to illustrate forecast exercise. This paper's method does not require a forecaster to make an exact ex-ante determination of turning points in the output series which is being forecasted. ...

Causality and correlations of output and nominal variables in a real business cycle model
A dynamic general equilibrium economy in which output is exogenous with respect to money is calibrated and simulated following a procedure commonly used in real business cycle literature. It is then confronted with the key comovement patterns of output and nominal variables in the post-war U.S. time series data. The model economy performs well in matching key second moment patterns involving output, money and price. The model economy - with its embedded 'reverse causation' from output to money - also provides the means for carrying out a probabilistic appraisal of the observed money to output ...

Expectations, credibility, and disinflation in a small macroeconomic model
We use a version of the Fuhrer-Moore model to study the effects of expectations and central bank credibility on the economy's dynamic transition path during a disinflation. Simulations are compared under four different specifications of the model that vary according to the way that expectations are formed (rations versus adaptive) and the degree of central bank credibility (full versus partial). In general, the various specifications exhibit qualitatively similar behavior and can reasonably approximate the trend movements in U.S. macro variables during the Volcker disinflation of the early ...
