“…First, they do not simulate the impact of inflation targeting relative to other possible policy regimes, such as the real targeting regime discussed below. Second, the model is based on estimates of potential output that are themselves affected by monetary policy (se, e.g., Tobin, 1980;Michl, 2007). Hence, if monetary policy slows economic growth, it also lowers the rate of growth of potential output and, therefore reduces the gap between the two, thereby appearing to stabilize the economy.…”
