請教研究所總經兩題（排擠效果＆失業率） - 經濟

請益版上大大以下兩題



Given the other things being equal, assume that the private sector would raise funds
by issuing bonds of 50 million. Now the government also issue bond to expend
the spending of 100 million.Which of the following statements is false?

(A) The supply of Bond would increase to 150 million and the interest rate
would increase in case of No crowding out effect

(B) The supply of Bond and the interest rate would Not increase in case of
complete crowding out effect

(C) The supply curve of Bond would sharply shift to the right and the
interest rate would increase in case of excessive crowding out effect

(D) The supply curve of Bond would slightly shift to the right and the
interest rate would increase in case of incomplete crowding out effect

這題我理解B選項為錯
但是A,C,D不太了解
A選項如果發生無排擠效果應該利率不會上升,為何會是正確的
C選項的excessive crowding out effect是指什麼情況


If the income taxes on wages increase, the labor supply curve will shift left,
but what happens to the unemployment rate

a. It unambiguously falls because the labor participation rate changes.

b. It unambiguously falls because some workers drop out of the workforce.

c. It unambiguously rises because some workers drop out of the workforce.

d. It is ambiguous because some workers drop out of the workforce.

e. None of the above is correct.


首先要如何得知在未變化前是勞力市場均衡還是有失業

若原先處在w高於市場結清工資,供過於求有失業,則供給線左移後失業會下降,

但因仍供過於求,就業量仍等於勞力需求,不變（楊莉總經有一題為此觀念）

若原先為均衡狀態,供給左移後均衡就業量會減少,但不知失業量為何如何判斷失業率變化



問題有點長,感謝耐心解答～～
