问题如下:
Which of the following may not be the reason that the long-run aggregate supply curve shifting to the right?
选项:
A.supply of hunman capital
decrease in the supply of physical capital.
C.increase in the supply of labor.
解释:
B is correct.
An increase in an economy’s accumulated stock of capital equipment will increase potential output——a rightward shift in long-run aggregate supply curve.
考点:长期供给
解析:和成本相关的一类因素会影响短期供给而非长期供给,所以B选项是实物资本属于生产成本范畴,因此不入选。
A选项的名义工资以及C选项的劳动力供给都属于影响长期生产的因素。
题里面问的是哪一个原因不是影响LRAS的。
A选项,Supply of human capital,属于“装备”,长期短期都影响,错误。
B选项,也属于装备,但是是因为是DECREASE,所以应该导致Left shift,所以错在这里了。
C选项,也属于“装备”,长期短期都影响,错误。
原题目下面的解析有点问题吧?
