Economic policy when interest rates are zero

点击翻译按钮获取中文摘要

This Project studies economic policy when interest rates are zero. Low interest rate environments constrain monetary policy because central banks cannot lower rates to raise demand. We exploit recent international experience with zero rates to understand why new policies have had mixed success. We argue different outcomes across countries arise because of different degrees of credibility and familiarity with new policy initiatives. We provide empirical support for this view and study the consequences of imperfectly credible policy. We characterize how monetary policy (conventional and unconventional) and fiscal policy can be used to greatest effect in low interest rate environments and quantify the welfare implications for Australia.
