This paper focuses on simple rules for monetary policy which central banks have used in various ways to guide their interest rate decisions. Such rules, which can be evaluated using simulation and optimization techniques, were first derived from research on empirical monetary models with...

We examine the quantitative impact of the Federal Reserve's mortgage-backed securities (MBS) purchase program. We focus on how much of the recent decline in mortgage interest rate spreads can be attributed to these purchases. The question is more difficult than frequently perceived because of...

The paper generalizes the Taylor principle---the proposition that central banks can stabilize the macroeconomy by raising their interest rate instrument more than one-for-one in response to higher inflation---to an environment in which reaction coefficients in the monetary policy rule evolve...

Central bank balance sheet expansion is financed by commercial banks. It involves not just a substitution of liquid central bank reserves for other assets held by commercial banks, but also a counterpart alteration in commercial bank liabilities, such as in short-term deposits issued to finance...

The paper examines international issues that arise in the design and evaluation of macroeconomic policy rules. It begins with a theoretical investigation of the effects of fiscal and monetary policy in a two-country rational expectations model with staggered wage and price setting and with...

The paper develops a two-country model with flexible exchange rates and perfect capital mobility, for evaluating the alternative macroeconomic policy rules. Macroeconomic performance is measured in terms of fluctuations in inflation and output. Expectations are rational, and prices are sticky;...

This paper reviews and contrasts different views about the role of expectations in policy research and practice. Recently, two widely different views seem to have dominated the analysis of policy questions.One view, which is referred to as the "new classical macroeconomic"view, is that...

The textbook optimal policy response to an increase in government debt is simple--monetary policy should actively target inflation, and fiscal policy should smooth taxes while ensuring debt sustainability. Such policy prescriptions presuppose an ability to commit. Without that ability, the...

During the recent economic crisis, when nominal interest rates were at their effective lower bounds, central banks used forward guidance announcements about future policy rates to conduct their monetary policy. Many policymakers believe that forward guidance will remain in use after the end of...

This paper studies a model in which a low monetary policy rate lowers the cost of capital for entrepreneurs, potentially spurring productive investment. Low interest rates, however, also induce entrepreneurs to lever up so as to increase payouts to equity. Whereas such leveraged payouts...
