Answer:
Inflection point occurs where increasing total product curve intersects 45 degree line
Step-by-step explanation:
he marginal product of a factor will change at different levels of employment of the factor. It has been found that marginal product of a factor rises in the beginning and then ultimately falls as more of it is used for production, other factors remaining the same.
That is why in Fig. 16.2 marginal product (MP) of labour as measured by the slopes of the tangents drawn to the total product curve TP at various points has been shown to be rising in the beginning and then diminishing till it becomes zero at the maximum point G of the total product curve.
Thereafter, the marginal product of labour becomes negative. The relationship between average product and marginal product and how both of them are related to the total product will be explained in detail in our analysis of the law of variable proportions.
the same rule for profit maximisation still applies. The firm maximises profit where MR=MC (at Q1).
For a firm in perfect competition, demand is perfectly elastic, therefore MR=AR=D.
This gives a firm normal profit because at Q1, AR=AC.
