a) It is true that the Bank of Tanzania cannot control inflation in the rest of the world, as it is a global phenomenon.
b) Standard monetary policies to reduce inflation may not work effectively in this environment, as the inflation is driven by external factors such as oil price shocks and global inflation. In this case, the BoT may need to consider alternative measures to mitigate the impact of imported inflation on the domestic economy.
c) Whether Tanzania has a fixed exchange rate or not may have an impact on how the country can respond to imported inflation. If Tanzania has a fixed exchange rate, it may limit the flexibility of the BoT to adjust monetary policy to address inflation. In such a case, the government may need to implement other policies such as supply-side reforms to address the impact of imported inflation on the economy.
