The price puzzle and indeterminacy in an estimated DSGE model
We extend Lubik and Schorfheide's (2004) likelihood-based estimation of dynamic stochastic general equilibrium (DSGE) models under indeterminacy to encompass a sample period including both determinacy and indeterminacy by implementing the change-point methodology (Chib, 1998). The most striking finding about the indeterminacy regime, which is estimated to coincide with the Great Inflation of the 1970s, is that it exhibits the price puzzle, in that the inflation rate rises immediately and in a sustained manner following a positive interest rate shock. Thus, the price puzzle might have been a ...
Discrete monetary policy changes and changing inflation targets in estimated dynamic stochastic general equilibrium models
Many estimated macroeconomic models assume interest rate smoothing in the monetary policy equation. In practice, monetary policymakers adjust a target level for the federal funds rate by discrete increments. One often-neglected consequence of using a quarterly average of the daily federal funds rate in empirical work is that any change in the target federal funds rate will affect the quarterly average in the current quarter and the subsequent quarter. Despite this clear source of predictable change in the quarterly average of the federal funds rate, the vast bulk of the literature that ...
