Giffen good的无差异曲线与预算线图像的识别
|
解答要点 |
|
● 由于I线为最初的无差异曲线,因此与之相切的JK为初始预算线而JL为后期预算线,预算线的向右旋转意味着价格的下降。 ● 最初的无差异曲线I与最初的预算线JK切在M处,因此对应的数量应该为B选项对应的数量。 ● Giffen good的特征为价格下降时,需求量也随之下降。因此后期的数量应该在B选项数量的左侧,即A选项是唯一合理的数量位置,A选项正确。

negative income tax对平等的影响
|
解答要点 |
|
● 从图像上分析可知,高收入人群交税更多(横轴上方部分,NT1高于NT),而低收入人群获得补贴更多(横轴下方部分,NT1低于NT)。这意味着不工作能得到更多的钱,工作赚钱却需要交更多的税,所以人们工作热情较低。但收入差距进一步缩小。因此D选项正确。

minimum wage的影响
|
解答要点 |

● 高于原市场工资水平的最低工资是有效的,这意味着此时劳动力的供给将大于需求,产生surplus,这部分劳动力将失业,其中包括一些原来有工作的工人,因此D选项符合题意,正确。 ● A选项,并非所有员工都会收到新的最低工资,原本工资水平高于最低工资的员工还会按照原工资发放。 ● B选项,由于最低工资高于原工资,因此会有更多的劳动力被吸引到该行业,而非更少,B错误。 ● C选项,同D选项的解释,此时会用一部分原来用工作的工人失业,所以并非增加,C错误。

quota带来的福利损失
|
解答要点 |
|
● 由于quota的存在,市场上的产品数量将减少为OQt,价格会抬升。 ● 此时consumer surplus由V+W+X减少为V,共损失W+X,但W转移给了生产商作为利润的一部分,实际净损失了X。 ● 此时原producer surplus因为产量减少了QQt而损失了Z。 ● 因此总的福利损失应为X+Z,C选项正确。
