In this seminar, Benjamin Wong develops a model to empirically study the influence of foreign shocks in driving trend inflation and the inflation gap. He first applies his model to Australia, Canada, New Zealand, Norway, and Sweden, five advanced inflation targeting small open economies. A broad summary of his results suggest that while foreign shocks can have a sizeable influence on the inflation gap, they play a more marginal role in driving trend inflation. The author also finds that much of the influence of foreign shocks in the inflation gap may be reflecting commodity price shocks. Wong’s conclusions are further validated by extending his study to a more heterogeneous group of Asian economies. In sum, his results are consistent with the idea that while foreign shocks may have a short to medium run impact on inflation deviating from its long- run level, long-run or trend inflation is ultimately a monetary phenomenon largely determined by domestic monetary policy.
