Equation of Exchange: MV = PQ M = Money Supply V = Velocity of Money P = Price Level (CPI) Q = Real GDP PQ = Nominal GDP MV = GDP V is Stable if M2 is the money supply Long Run –Q is constant at the Natural (potential) GDP. Increases in M cause inflation Long Run Phillips Curve Long Run Aggregate Supply At the Potential GDP with Expected Price Level
Policy Rules: Increasing the M at a constant rate to increase the aggregate demand at the same rate as the aggregate supply promote economic growth without increasing inflation Policy Rules: Increasing the M at a constant rate to increase the aggregate demand at the same rate as the aggregate supply promote economic growth without increasing inflation
