Central banks have too many objectives
One might expect an economic policy implementing institution to have as many tools as objectives. Central banks have two tools: short-term interest rates and asset purchases (mainly of bonds). But in the recent period, they have been given many more than two objectives . They must: Combat inflation; Combat financial instability; Maintain debt sustainability; Reduce inequality and unemployment; Support the energy transition and investment. When a n economic policymaking institution has many more objectives than tools, it becomes ineffective because it has to find a compromise between these objectives and generates a lot of dissatisfaction with its performance.
