One of the important determinants of the response of saving and consumption to the real interest rate is the elasticity of intertemporal substitution. That elasticity can be measured by the response of the rate of change of consumption to changes in the expected real interest rate. A detailed...

In a market-clearing economy, declines in demand from one sector do not cause large declines in aggregatge output because other sectors expand. The key price mediating the response is the interest rate. A decline in the rate stimulates all categories of spending. But in a low-inflation economy,...

During World War II and the Korean War, real GDP grew by about half the amount of the increase in government purchases. With allowance for other factors holding back GDP growth during those wars, the multiplier linking government purchases to GDP may be in the range of 0.7 to 1.0, a range...

Macroeconomists----especially those studying monetary policy----often view the business cycle as a transitory departure from the smooth evolution of a neoclassical growth model. Important ideas contributed by Friedman, Lucas, and the developers of the sticky-price macro model generate this type...

This paper sets forth a simple general structural model of aggregate output, the interest rate, and the price level. The core of the model is the determination of the level of output as a product-market equilibrium, either competitive or oligopolistic, possible indeterminate because of...

General-equilibrium models for studying monetary influences in general and the zero lower bound on the nominal interest rate in particular contain implicit theories of unemployment. In some cases, the theory is explicit. When the nominal rate is above the level that clears the current market for...

This paper discusses nominal income targeting as a possible rule for the conduct of monetary policy. We begin by discussing why a rule for monetary policy may be desirable and the characteristics that a good rule should have. We emphasize, in particular, three types of nominal income targets,...

The immediate effect of Friedman's 1968 AEA presidential address on the economics profession was the introduction of an adaptive term in the Phillips curve that shifted the curve, as Friedman proposed, based on expected inflation. Initial formulations suggested that the shift was less than...

Today, all major central banks pay or collect interest on reserves, and stand ready to use the interest rate as an instrument of monetary policy. We show that by paying an appropriate rate on reserves, the central bank can pin the price level uniquely to a target. The essential idea is to index...

Since 2008, the central banks of advanced countries have borrowed trillions of dollars from their commercial banks in the form of interest-paying reserves and invested the proceeds in portfolios of risky assets. We investigate how this new style of central banking affects central banks'...
