请益版上大大以下两题 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 这题我理解B选项为错 但是A,C,D不太了解 A选项如果发生无排挤效果应该利率不会上升,为何会是正确的 C选项的excessive crowding out effect是指什麽情况 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变化前是劳力市场均衡还是有失业 若原先处在w高於市场结清工资,供过於求有失业,则供给线左移後失业会下降, 但因仍供过於求,就业量仍等於劳力需求,不变（杨莉总经有一题为此观念） 若原先为均衡状态,供给左移後均衡就业量会减少,但不知失业量为何如何判断失业率变化 问题有点长,感谢耐心解答～～ --
