The potential for large, shallow earthquakes and their associated seismic hazard in the eastern Caucasus, an area of dense population and sensitive industrial infrastructure, remains speculative based on historical precedent and current geologic and seismologic observations. Here we present...

How should policy be optimally designed when a monetary authority faces a private sector that is skeptical about policy announcements and makes inferences about the monetary authority’s ability to follow through on policy plans from economic data? To provide an answer to this question, we...

How should policy be optimally designed when a monetary authority faces a private sector that is somewhat skeptical about policy announcements and which interprets economic data as providing evidence about the monetary authority's preferences or its ability to carry through on policy plans? To...

Inflation targeting is a monetary policy rule that has implications for both the average performance of an economy and its business cycle behavior. We use a modern, rational expectations model to study the twin effects of this policy rule. The model highlights forward- looking consumption and...

This paper explores the implications of rational expectations and the aggregate supply theory advanced by Lucas (1973) for analysis of optimal monetary policy under uncertainty along the lines of Poole (1970), returning to a topic initially treated by Sargent and Wallace (1975). Not...

This paper describes a simple model of technology adoption which combines the two engines of growth emphasized in the recent growth literature: human capital accumulation and technological progress. Our model economy does not create new technologies, it simply adopts those that have been created...

Using a simple modern macroeconomic model, we argue that the real effects of the Volcker disinflation in the early 1980s were mainly due to imperfect credibility, evident in volatility and stubbornness of long-term interest rates. Studying recently released transcripts of the Federal Open Market...

In a plain-vanilla New Keynesian model with two-period staggered price-setting, discretionary monetary policy leads to multiple equilibria. Complementarity between the pricing decisions of forward-looking firms underlies the multiplicity, which is intrinsically dynamic in nature. At each point...
