This is one of my homework questions: "Monetary authorities often try to influence inflation by making pronouncements carefully designed to influence various markets. This can take the form of being conspicuously optimistic, or overly pessimistic, soothing or threatening. Describe the channels by which 'central bank talk' might affect the inflation rate in an economy."
