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...

In analyses of "liquidity trap" problems associated with the zero lower bound (ZLB) on nominal interest rates, it is important to emphasize the difference between policy rule changes, intended to help escape an existing ZLB situation, and maintained policy rules designed so as to avoid ZLB...

The fiscal theory of the price level (FTPL) has attracted much attention but disagreement remains concerning its defining characteristics. Some writers have emphasized implications regarding interest-rate pegging and determinacy of RE solutions, whereas others have stressed its capacity to...

Our current inflation stemmed from a fiscal shock. The Fed is slow to react. Why? Will the Fed's slow reaction spur more inflation? I write a simple model that encompasses the Fed's mild projections and its slow reaction, and traditional views that inflation will surge without swift rate rises....

We consider what, if any, relationship there is between monetary aggregates and inflation, and whether there is any substantial reason for modifying the current mainstream mode of policy analysis, which frequently does not consider monetary aggregates at all. We begin by considering the body of...
