In a stylized world, where there is a single monetary policymaker who has considerable confidence in a model of the economy, effective communication would include a forecast derived from this model. This forecast would incorporate a policy path that yields the best economic outcomes based on that single policymaker’s views. However, we don’t live in such a simple world.
Monetary policymaking is often conducted by committee, and divergent views can and often do exist. While this can be clumsy at times, such governance mechanisms have great strength in preventing institutions from lapsing into groupthink by ensuring that various views are heard in an environment that promotes better decisions and outcomes and helps to preserve central bank independence and accountability.
