我想求助一下原版书后的reading 15的第23题
For a manufacturing company to achieve the most efficient combination of labor and capital, and therefore minimize total costs for a desired level of output, it will most likely attempt to equalize the:
A average product of labor to the average product of capital.
B marginal product per unit of labor to the maginal product per unit of capital.
C marginal product obtained per dollar spent on labor to the marginal product per dollar spent on capital.
请问这道题应该如何理解，另外这道题考的是哪个知识点？非常感谢。作者: apf薛老师 时间: 2013-9-14 09:34
这道题考的是资源（labor和capital）如何配置将会使得成本最低，公式在原版书P135的公式8。
参考书上P135最后一段，if MPL/PL =2, MPK/PK=4, physical capital yields twice the output per monetary unit of input cost versus labor。因此此时capital的使用效率更高，我们更倾向于使用capital，如果一直持续使用capital，会有边际递减的效果，最终使得这两个比值相同。
