Abstract
This paper compares the capability of simple inflation targeting (IT) and price-level-path targeting (PLPT) rules to minimize inflation and output gap variability in a two-country, two-sector version of the Global Economy Model calibrated for Canada and the United States. We find that simple PLPT rules are slightly better than simple IT rules at macroeconomic stabilization and that the presence of terms-of-trade shocks tends to bolster the case for PLPT. Lastly, we demonstrate that the choice of monetary policy framework in the United States does not affect the relative merits of IT vs. PLPT in Canada.
