The paper sets out and analyzes a simple model of money, banking, and price level determination. The model is first used to illustrate recent developments in the theory and analysis of banking, particularly the distinction between the portfolio management services provided by banks and their...

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...

Modern theory has delivered both the conservative central banker and the principal-agent approaches as rationales for the independence of the central bank. The principal-agent approach directs attention to the importance of both clearly defining the goals of the central bank and its command in...

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 exchange rate has by 1984 become as central to United States economic policy discussions as it has long been in the rest of the world. In this paper we show how the standard closed-economy macroeconomic model -- the Phillips curve augmented IS-LM analysis -- has to be modified for the United...

A country that decides to fix its exchange rate thereby gives up control over its own inflation rate and the determination of the revenue received from seigniorage. If the country goes further and uses a foreign money, it loses all seigniorage. This paper uses an optimal inflation tax approach...

The paper examines the case for activist monetary policy. It accepts the view that expectations are formed rationally, but not the implication of flexible price, equilibrium, rational expectations models, that monetary policy cannot and should not be used to affect real magnitudes. The paper...

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...

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...

We investigate the transmission of central bank liquidity to bank deposits and loan spreads in Europe over the period from January 2006 to June 2010. We find evidence consistent with an impaired transmission channel due to bank risk. Central bank liquidity does not translate into lower loan...
