我不太懂這題英文題的意思，它是指說投資水準比什麼的變動對均衡所得的變
動較大，是這個意思嗎??

2. If the consumption funciton is given by C= 50+0.6Yd, where Yd is

the disposable income, then an increase in goverment spending of 10

units financed by a tax increase of 10 units will cause.

a. output to rise by 0.5 units.

b. output to rise by 2.5 units.

c. output to rise by 15 units.

d. output to rise by 10 units.

e. no change in output.

這題我在想，因為政府支出跟課稅額度一樣，那是不是平衡預算?
因為ΔG=ΔT這個不是平衡預算嗎??那所得不是就不變嗎??
我這個想法我也覺得有錯，但我實際是哪不對了??
因為我後來仔細算過最後會上升十單位
