Consider a simple macro model with a constant price-level and demand-determined output. The equations of the model are: - c = 175 + 0.75YD - I: 125 - G = 200 - T = 0.15Y - X = 125 - IM = 0.25Y The simple multiplier in this economy is: (Answer to one decimal point.) Consider a simple macro model with a constant price-level and demand-determined output. The equations of the model are: . c = 200 + 0.75vD . I: 180 . G = 120 . T = 0.20Y - X = 100 - IM = 0.25Y Assume that potential output in this economy is Y* = 1180. What is the required change in government spending, G, required so that equilibrium income is equal to potential output. (Nearest dollar, positive is an increase, negative is a decrease.) Consider a simple macro model with a constant price-level and demand-determined output. The equations of the model are: . C = 1925 + 0.90YD . 1 = 675 . G = 1125 . T = 0.10Y . X = 925 . IM = 0.25Y The equilibrium income in this economy is: (Nearest dollar.)Consider a simple macro model with a constant price-level and demand-determined output.
