Perfect simulation of stationary equilibria

Abstract

Using a variation of the coupling from the past technique, this paper develops algorithms which generate independent observations from the stationary distributions of various dynamic economic models. These variates can be used for calibration, calculation of steady state phenomena, and simulation-based estimation. As an application, we demonstrate how to generate exact samples from the stationary distribution of an incomplete markets model routinely calibrated by macroeconomists. Our implementation generates 100,000 independent draws from the stationary distribution in less than 3s.
