Central Bank Policy Flexibility
During a severe economic downturn, a central bank's primary tool is to lower interest rates to stimulate the economy. Explain the mechanism by which a higher long-term inflation target (e.g., 4%) could give a central bank more effective policy options in such a crisis compared to a lower inflation target (e.g., 1%), particularly when its main policy interest rate cannot be reduced below zero.

Two countries are facing a severe economic recession. Both of their central banks determine that to stimulate economic activity, they need to achieve a target real interest rate of -3%. Country A has historically maintained an average inflation rate of 1%. Country B has historically maintained an average inflation rate of 4%. Assuming both central banks cut their nominal policy interest rates as low as they can go (to zero), which of the following outcomes is most likely?

Central Bank Policy Dilemma
If a central bank is constrained by the fact that it cannot set its policy interest rate below zero, a higher prevailing rate of inflation makes it more difficult for the bank to achieve a negative real interest rate to stimulate the economy.
