Recent monetary policy experience suggests a simple test for models of monetary non-neutrality. Suppose the central bank pegs the nominal interest rate below steady state for a reasonably short period of time. Familiar intuition suggests that this should be inflationary. We pursue this simple...

Recent monetary policy experience suggests a simple diagnostic for models of monetary non-neutrality. Suppose the central bank pegs the nominal interest rate below steady state for a reasonably short period of time. Familiar intuition suggests that this should be modestly inflationary, and a...

Observations that the Phillips curve may be deviating from historical norms are important to policymakers because deviations would imply that more or less output has to be sacrificed to achieve a permanent reduction in long-term inflation. But we argue that recent economic shocks and a shift in...

Is inflation (in the often-quoted words of Milton Friedman) "always and everywhere a monetary phenomenon"? Some say no, arguing that inflation is controlled not only by the central bank but also by the fiscal authority. This Commentary authors explore their argument, known as the fiscal theory...

It is well known that sunspot equilibria may arise under an interest-rate operating procedure in which the central bank varies the nominal rate with movements in future inflation (a forward-looking Taylor rule). This paper demonstrates that these sunspot equilibria may be learnable in the sense...
