Optimal monetary policy is studied in a model with no contractual restrictions or physical costs of changing prices. Nevertheless, the price level is sticky in a range of markup indeterminacy, and inflation occurs only when employment presses against capacity. Under full information, the...

The paper proposes three options for overcoming the zero bound on interest rate policy: a carry tax on money, open market operations in long bonds, and monetary transfers. A variable carry tax on electronic bank reserves could enable a central bank to target negative nominal interest rates. A...

The paper assesses the role of a Reserve Bank in the Federal Reserve System. It compares the Eurosystem with the Fed System, and offers suggestions for the Eurosystem based on the Fed's experience. A regional presence facilitates surveillance of the economy and helps a central bank to...

Central bank or International Monetary Fund lending should be regarded as a line of credit, analogous to private line-of-credit products. Contractual provisions in private line-of-credit arrangements are designed to control managerial moral hazard and provide a means for profit-maximizing...

The paper explores the relationship between financial stability, deflation, and monetary policy. A discussion of narrow liquidity, broad liquidity, market liquidity, and financial distress provides the foundation for the analysis. There are two preliminary conclusions. Equity prices are a...

Reasoning within the New Neoclassical Synthesis (NNS) we previously recommended that price stability should be the primary objective of monetary policy. We called this a neutral policy because it keeps output at its potential, defined as the outcome of an imperfectly competitive real business...

It takes many years for more efficient electronic payments to be widely used, and the fees that merchants (consumers) pay for using those services are increasing (decreasing) over time. We address these puzzles by studying payments system evolution with a dynamic model in a two-sided market...

Paying with a mobile phone is a cutting-edge innovation transforming the global payments industry. However, some advanced economies like the U.S. are lagging behind in mobile payment adoption. We construct a dynamic model with sequential payment innovations to explain this puzzle, which uncovers...

Macroeconomics is moving toward a New Neoclassical Synthesis, which like the synthesis of the 1960s melds Classical with Keynesian ideas. This paper describes the key features of the new synthesis and its implications for the role of monetary policy. We find that the New Neoclassical Synthesis...

The evolution and structure of the payments system is explained by efficiency gains from substituting claims on particular institutions for commodity money. Information-intensive lending and payments services have been provided jointly by the same set of institutions, i.e., banks, because...
