单选题 If both average product (AP) and marginal product (MP) are equal to 8 when 10 workers are employed, what can we most likely conclude about AP and MP when 15 workers are employed?
  • A. AP=MP=5
  • B. AP=4 and MP=6
  • C. AP=7 and MP=5
【正确答案】 B
【答案解析】[解析] 由下图可知，当劳动L投入量(雇用工人数量)超过AP=MP所对应的水平后，AP和MP均会有所下降，且MP小于AP。因此，选项B最符合题意要求。 [*]
