Government purchase are 1000. Desired consumption and desired investment are given by C^d =3000 -2000r+ 0.10Y I^d =1000 -4000r where Y is output and r is the expected real interest rate. (a)Find the real interest rate that clears the goods market. Assume that that output equals full-employment output. （Hint:S^d =Y -C^d -G ， S^d = I^d ）(5分) (b)Calculate the amount of saving,investment,and consumption in equilibrium. (10分) (c)If a shock to wealth causes desired consumption to decline by 200(so that the new equation for desired consumption is C^d = 2800 -2000r +0.10Y),find the equilibrium real interest rate, saving, investment,and consumption. Ans:(a)0.083 (b)S^d=666.67 ,I^d=666.67 ,C^d=3,333.33 (c)r=0.05 ,S^d=800 ,I^d=800 ,C^d=3200 2.假设货币需求函数给定如下:M^d/P =640+ 0.1Y -5000(r+πe)，且中央银行根据所得与 通货膨胀决定名目货币供给，所以货币供给函数如下:M^s =1000+ 0.1Y -4000π (a)若预期通货膨胀率π^e =π=0.03, Y=1000,且r =0.02 ,请你算出物价水准为何? （Hint:P =M^s/L(Y,r+π^e) (5分) (b)若只有通货膨胀率π上升至0.04，而π^e与其他(a)题的条件不变，请你算出物价水 准为何?
