Consider the government spending G and taxes T as given. Assume no output growth, that is gY = 0. The central bank uses a contractionary monetary policy by decreasing the inflation target from 5% to 4%. Ceteris paribus, what would happen to the following in the medium-run? (a) (2.5 marks) The natural level of output, Yn. (b) (2.5 marks) Money growth, gM. (c) (2.5 marks) Real interest rate. (Hint: The natural real interest rate, rn, is the real interest rate needed to sustain G when the output is at its natural level, Yn.) (d) (2.5 marks) Nominal interest rate.
