The study looked at how unconventional monetary policies affected a small open economy like Canada. By using shadow interest rates to measure these policies during a period of low interest rates, the researchers found that both Canadian and US unconventional monetary policies boosted Canadian industrial production. Specifically, Canadian unconventional policy increased output by 0.013% per month, while US policy raised it by 0.127% per month. This shows that unconventional monetary policies can help the economy grow, and that foreign policies can also benefit a small open economy like Canada.
