The fiscal theory of the price level can describe monetary policy. Governments can set interest rate targets and thereby affect inflation, with no change in fiscal surpluses. The same basic mechanism describes interest rate targets, forward guidance, open market operations, and quantitative...

If one accepts the new-Keynesian solution, the parameters of the Taylor rule relating interest rates to inflation and other variables are not identified without unrealistic assumptions. Thus, Taylor rule regressions cannot be used to argue that the Fed conquered inflation by moving from a...

The parameters of the Taylor rule relating interest rates to inflation and other variables are not identified in new-Keynesian models. Thus, Taylor rule regressions cannot be used to argue that the Fed conquered inflation by moving from a passive to an active policy in the early 1980s

The new-Keynesian, Taylor-rule theory of inflation determination relies on explosive dynamics. By raising interest rates in response to inflation, the Fed does not directly stabilize future inflation. Rather, the Fed threatens hyperinflation or deflation, unless inflation jumps to one particular...

We measure monetary policy shocks as changes in the Fed funds target rate that surprise bond markets in daily data. These shock series avoid the omitted variable, time-varying parameter, and orthogonalization problem of monthly VARs, and do not impose the expectations hypothesis. We find...

The new-Keynesian, Taylor-rule theory of inflation determination relies on explosive dynamics. By raising interest rates in response to inflation, the Fed induces ever-larger inflation or deflation, unless inflation jumps to one particular value on each date. However, economics does not rule out...
