Daily quiz-27 (04/08): Print your name and ID in BLOCK letters. Suppose GDP = $14 trillion, Consumption = $8 trillion, G = $4 trillion, T = 4 trillion. Q1. Calculate equilibrium investment. Ans: Investment = national saving = 2 trillion Q2. Suppose income taxes are cut by 200 billion and consumers save all of the extra disposable income. How does equilibrium investment change? Ans: new private saving = 14 – 3.8 – 8 = 2.2 trillion, change in private saving = +0.2 trillion, new public saving = 3.8 – 4 = - 0.2 trillion, change in public saving = - 0.2 trillion, change in investment = change in national saving = + 0.2 – 0.2 = 0 trillion. Q3. Suppose income taxes are cut by 200 billion and consumers spend ¾ ths of the extra disposable income and save the rest. How does the equilibrium investment change? Ans: new private saving = 14 – 3.8 – 8.15 = 2.05 trillion, change in private saving = + 0 .05 trillion, change in national saving = + 0.05 – 0.2 = - 0. 15 trillion = change in investment. Investment falls.
