QUESTION 1 In the classical model, the government raises lump-sum taxes on income by $100 billion, and the economy adjusts so that output does not change. If the marginal propensity to consume is (16, national saving: "'5 4* rises by $100 billion. "7 E'- rises by $60 billion. "7 C- falls by $50 billion. '1" D-falls by $100 billion. QUESTION 2 In the classical model, assume that equilibrium GDP (Y) is 6,000. Consumption {C} is given by the equation C = 500 + t].?5{ir' T}. Taxes {T} are equal to 300. Government spending is 600. In this case, equilibrium investment is: "7 'L 500. "7 E1-1,000. "7 c- 1,500.
