Recent monetary history has been characterized by monetary authorities that appear to shift periodically between distinct policy regimes associated with higher or lower average rates of money creation.

Several approaches to finding the second-order approximation to a dynamic model have been proposed recently. This paper differs from the existing literature in that it makes use of the Magnus and Neudecker (1999) definition of the Hessian matrix. The key result is a linear system of equations...

Reasonably calibrated versions of the Diamond-Mortensen-Pissarides search and matching model of unemployment underpredict, by a wide margin, the volatility of vacancies, unemployment, and the vacancies-unemployment ratio - variables at the heart of this model. These shortcomings motivate two...

Recent financial crises in Europe as well as the periodic battles in the U.S. over the debt ceiling point to the importance of fiscal discipline among developed countries. This paper develops an open economy model, calibrated to the U.S. and a subset of the EMU, to evaluate the impact of various...
