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,...

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...

Over the past few decades, worldwide real interest rates have trended downward. The real interest rate describes the terms of trade between risk-tolerant and risk-averse investors. Debt pays off equally across contingencies at a given future date, so debt is valuable to risk-averse investors to...

Output per worker varies enormously across countries. Why? On an accounting basis, our analysis shows that differences in physical capital and educational attainment can only partially explain the variation in output per worker we find a large amount of variation in the level of the Solow...

Output per worker varies enormously across countries. Why? Our analysis shows that differences in governmental, cultural, and natural infrastructure are important sources of this variation. According to our results, a high-productivity country (i) has institutions that favor production over...

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'...
