A central equation for the fiscal theory of the price level (FTPL) is the government budget constraint (or "government valuation equation"), which equates the real value of government debt to the present value of fiscal surpluses. In the past decade, the governments of most developed economies...

We review the role of the central bank's (CB) balance sheet in a textbook monetary model, and explore what changes if the central bank is allowed to pay interest on its liabilities. When the central bank cannot pay interest, away from the zero lower bound its (real) balance sheet is limited by...

Macroeconomic and microeconomic data paint conflicting pictures of price behavior. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model which resolves this apparent micro - macro conflict. Our...

A policy of forward guidance has been suggested either as a form of commitment (\Odyssean") or as a way of conveying information to the public (\Delphic"). I analyze the strategic interaction between households and the central bank as a game in which the central bank can send messages to the...

We study the interplay between monetary policy and financial conditions shocks. Such shocks have a significant and similar impact on the real economy, though with different degrees of persistence. The systematic fed funds rate response to a financial shock contributes to bringing the economy...

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these...

What are the economic effects of an interest rate cut when an economy is in the midst of a financial crisis? Under what conditions will a cut stimulate output and employment, and raise welfare? Under what conditions will a cut have the opposite effects? We answer these questions in a general...
