I analyze monetary policy with interest on reserves and a large balance sheet. I show that conventional theories do not determine inflation in this regime, so I base the analysis on the fiscal theory of the price level. I find that monetary policy can peg the nominal rate, and determine expected...

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 study optimal monetary policy during temporary supply contractions when aggregate demand has inertia and expansionary policy is constrained. In this environment, it is optimal to run the economy hot until supply recovers. Positive output gaps in the low-supply phase lessen the negative output...

I construct a simple model with sticky prices and interest rate targets, closed by fiscal theory of the price level with long-term debt and fiscal and monetary policy rules. Fiscal surpluses rise following periods of deficit, to repay accumulated debt, but surpluses do not respond to arbitrary...

Unexpected inflation devalues nominal government bonds. It must therefore correspond to a decline in expected future surpluses, or a rise in their discount rates, so that the real value of debt equals the present value of surpluses. I measure each component via a vector autoregression, in...

Should monetary policy have a prudential dimension? That is, should policymakers raise interest rates to rein in financial excesses during a boom? We theoretically investigate this issue using an aggregate demand model with asset price booms and financial speculation. In our model, monetary...

We analyze optimal monetary policy when asset prices influence aggregate demand with a lag (as is well documented). In this context, as long as the central bank's main objective is to minimize the output gap, the central bank optimally induces asset price overshooting in response to the...

Central banks (the Fed) and markets (the market) often disagree about the path of interest rates. We develop a model that explains this disagreement and study its implications for monetary policy and asset prices. We assume that the Fed and the market disagree about expected aggregate demand....

In this paper we: (i) provide a model of the endogenous risk intolerance and severe aggregate demand contractions following a large real (non-financial) shock; and (ii) demonstrate the effectiveness of Large Scale Asset Purchases (LSAPs) in addressing these contractions. The key mechanism stems...

I use the valuation equation of government debt to understand fiscal and monetary policy in and following the great recession of 2008-2009, to think about fiscal pressures on US inflation, and what sequence of events might surround such an inflation. I emphasize that a fiscal inflation can come...
