It has been argued that the Great Inflation of the 1970s has been caused by a Federal Reserve policy that was not aggressive enough in combatting inflation. This led to a scenario where the U.S. economy operated under an indeterminate equilibrium with sunspot shocks becoming a driving force...

The monetary policy literature has recently devoted considerable attention to Taylor-type rules, in which the interest rate set by the central bank depends on measures of inflation and aggregate output. We show that if policy-makers attempt to choose the optimal rule within a Taylor-type...

Do international business cycles only represent optimal responses by rational agents to erratic changes in technology, or are they also influenced by factors that are unrelated to fundamentals? This paper addresses this issue by exploring the role of such non-fundamental factors in improving...

Lubik and Schorfheide (2004) extend estimated DSGE models to address monetary policy indeterminacy. Their method leads to an all-or-none classification of a time period as having determinate or indeterminate monetary policy. Sub-sample estimates indicate, however, that U.S. monetary policy might...

There is considerable disagreement in the empirical macro literature as to the degree of returns to scale in U.S. output. While many studies find evidence of a small degree of increasing returns, standard errors are typically large. This issue is of importance for assessing the possibility of...

We study identification in a class of three-equation monetary models. We argue that these models are typically not identified. For any given exactly identified model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...
