Monetary Policy with Interest on Reserves
Journal of Economic Dynamics & Control 49 (2014), 74-108. ( ScienceDirect link to published version, html and pdf) I analyze monetary policy with interest on reserves and a large balance sheet. I argue for the desirability of this regime on financial stability grounds. 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 -- buying and selling government debt with no effect on surpluses -- can peg the nominal rate, and determine expected inflation. With sticky prices, monetary policy can also affect real interest rates and output, though not with the usual signs in this model. Figures 2 and 3 are the best part -- the effects of monetary policy with and without fiscal coordination. I address theoretical controversies, and how the fiscal backing of monetary policy was important for the 1980s disinflation. A concluding section reviews the role of central banks. Matlab program.
