Abstract We investigate unconventional monetary policy in a small open economy using shadow interest rates to capture policy at the zero lower bound (ZLB) in a Bayesian structural vector autoregressive model for Canada - a useful case where foreign shocks can be proxied by the U.S. alone. We estimate that during the ZLB period, on average, Canadian unconventional monetary policy increased output by 0.13 percent, while US unconventional monetary policy increased Canadian output by 1.2 percent on average. Results demonstrate the effectiveness of domestic unconventional monetary policy and the strong spillovers from foreign unconventional monetary policy in a small open economy.

1 Introduction Following the 2008 global financial crisis, many central banks quickly exhausted their ability to stimulate economic activity as policy rates reached the zero lower bound (ZLB).1 To continue to encourage lending, they turned to unconventional measures, including direct market interventions through large scale asset purchases (LSAPs) and forward guidance, to influence expectations of the future short rate. Recent literature has quantified the effects of these policies on long term rates, asset prices, credit costs and (to a lesser extent) the real economy, and has generally focused on the domestic effects of such policies in large open economies, most notably the US.2 In contrast, this paper analyzes the effects of unconventional monetary policy measures in a small open economy, including spillovers from foreign unconventional monetary policy, a topic which has hitherto received relatively little attention.3 Specifically, we look at t
