问题如下:

The production relationship between the number of machine hours and total product for a company is presented below.

Diminishing marginal returns first occur beyond machine hour:

选项:

A.

3.

B.

4.

C.

5.

解释:

A is correct.

Diminishing marginal returns occur when the marginal product of a resource decreases as additional units of that input are employed. Marginal product, which is the additional output resulting from using one more unit of input, is presented below.

The marginal product of the third machine hour is 6 and declines thereafter. Consequently, diminishing marginal returns are first evident beyond three machine hours.

考点:边际效用递减

我们首先计算不同产量下的边际产量,如下表所示。

可以看到产量由3增加到4的时候,边际产量由6下降到5,所以产量3的边际效用开始出现递减。

题目问的是MR边际收益,为什么求的是MP呢?

嗨,爱思考的PZer你好:


同学你好,我们在这里面假定的是出售价格情况不变的情况下,一单位机器工时的增加对于产出的影响,对于价格不变的情况下,我们利用mp计算边际收益也是没问题的

NO.PZ2017100901000007 问题①minishing marginreturns first occur beyonmachine hour:这个问题问的不是MR递减首次出现在什么时候。那不是应该求MR吗 ②如果按照答案理解,求MP的拐点,答案是什么意思?每个MP咋求出来的?MP不是边际产量的意思吗?

A is correct. minishing marginreturns occur when the marginproof a resourcreases aitionunits of thinput are employe Marginproct, whiis the aitionoutput resulting from using one more unit of input, is presentebelow. The marginproof the thirmachine hour is 6 anclines thereafter. Consequently, minishing marginreturns are first evint beyonthree machine hours. 考点边际效用递减 我们首先计算不同产量下的边际产量,如下表所示。 可以看到产量由3增加到4的时候,边际产量由6下降到5,所以产量3的边际效用开始出现递减。题目中说的是beyon所以我第一反应就是在第四小时之前边际效益开始减少,而在第三小时之前还是在增加的。所以这类因为理解犯的错误怎么避免呢?
