五、简答题(每题l0分．计20分)

36．参考答案：

ab线，平行于横轴，表明价格水平不变，总供给不断增加，这是因为没有充分就业，资源没

有得到充分利用。在价格不变的情况下，可以增加供给。

bc线，从左下方向右上方倾斜，表明总供给和价格水平成同方向变化。这是在充分就业前或资源接近充分利用情况下，产量增加使生产要素价格上升、成本增加，最终使价格水平上升。这种情况是短期的，同时又是经常出现的。所以，这段总供给曲线被称为“短期总供给曲线”，或“正常的总供给曲线”。

cd线，垂直于横轴或平行于纵轴。表明价格水平变化，总供给量不变。这是因为已充分就业或资源得到充分利用，总供给量已无法增加，这是一种长期趋势。所以，这段总供给曲线称为“长期总供给曲线”。(4分)37．参考答案：

(1)政府税收与转移支付具有适应经济波动而自动增减，并进而影响社会总需求的特点，一般称这样的财政政策及其效应为财政制度的自动稳定器。(2分)

(2)在经济处于繁荣状态时，人们的收入增加，税收自动而及时地增加，失业保险、贫困救济、农产品支持价格等转移支付会减少，有助于抑制通货膨胀；而在经济衰退时期，税收自动而及时减少，各项转移支付的增加，又助于缓和经济的衰退。因此，自动稳定器能够减轻经济周期的波动幅度，降低波峰高度，提高谷底高度。(4分)

(3)但是，由于自动稳定器仅仅是对经济波动动作稳定性反应，在波动产生之前并不能发生作用。同时，它也不能充分调节社会需求，从而不能消除经济危机。因此，要实现充分就业、经济稳定增长以及物价稳定等目标，还必须依赖相机抉择的财政政策的积极作用。(4分)

六、计算题(第1题7分。第2题8分．计15 38．解：商品实现均衡时

也就是：20—3P=2+3PP=3(2分)

在价格P=3时，市场需求量为Il，于是需求价格弹性为

当P=3时的需求价格弹性为9／11，价格弹性小于1，属于缺乏弹性，厂商要扩大销售收入应采取提价策略。(2分)

39．(1)政府购买支出乘数KG；(2)税收乘数KT；(3)AG为20万元时的国民收入增长额；(4)AT为--20万元时的国民收入增长额；参考答案： 已知：b=0．85 G=20万元T=20万元

七、论述题(计15分)

40•画图说明完全竞争市场的长期均衡，并比较完全竞争与完全垄断的长期均衡有什么不同?

在短期内，完全竞争厂商虽然可以实现均衡，但由于不能调整生产规模，厂商在短期均衡时可能会有亏损。但在长期中，所有的生产要素的数量都是可变的，厂商就可以通过调整自身的规模或改变行业中厂商的数量来消除亏损，或瓜分超额利润，最终使超额利润为零，实现新的均衡，即长期均衡。(2分)

具体过程如下：

1)如果供给小于需求，价格水平高，即存在超额利润时，各厂商会扩大生产规模或行业中 有新厂商加入，从而使整个行业供给增加，市场价格下降，单个厂商的需求曲线下移，使超额利润减少，直到超额利润消失为止。(2分)

2)如果供给大于需求，价格水平低，即存在亏损时，则厂商可能减少生产规模或行业中有一些厂商退出，从而使整个行业供给减少，市场价格下升，单个厂商的需求曲线上移，直至亏损消失为止。(2分)

3)供给等于需求，实现长期均衡

在长期内由于厂商可以自由地进入或退出某一行业，并可以调整自己的生产规模，所以供给小于需求和供给大于需求的情况都会自动消失，最终使价格水平达到使各个厂商既无超额利润又无亏损的状态。这时，整个行业的供求均衡，各个厂商的产量也不再调整，于是就实现了长期均衡。其均衡条件是：MR=AR=MC=AC(2分)

4)完全竞争与完全垄断相比，其区别在于：第一，长期均衡的条件不同。完全竞争厂商的长期均衡的条件是：

P=MR—SMC=LMC—LAC=SAC。垄断厂商的长期均衡条件是：MR—LMC=SMC。

第二，长期均衡点的位置不同。完全竞争厂商长期均衡产生于长期平均成本曲线的最低点；而完全垄断厂商长期均衡不可能产生于长期平均成本曲线的最低点。

第三，获得利润不同。完全竞争厂商在长期均衡时只能获得正常利润；而完全垄断厂商由于其他厂商无法进入该行业，可以获得超额垄断利润。(5分)
