From the above table, it can be Observed that marginal product of labor is decreasing with each additional hours. It shows that diminishing return of labor in the production process. For example, first hour of labor, produces 6 units of product, but second hour of labor, produces 5 units of product and third hour of labor produces 4 units of product and so on... It shows that with each new hour of work, production level decreases. It shows that there is a diminishing return of labor.
C.
Optimal level of labor is applied, when MRAP of labor = wage rate of the labor
On the basis of above rule,
Optimal level of labor = 5 hours
Because, at 5th hour of labor,
MRAP of labor = 2*20 = $40
Wage of the labor = $40
So, optimal level of labor is achieved when work is done for 5 hours.

Suppose that a particular firm is in a perfectly competitive constant-cost industry. When it is using the optimal amount of capital for the long-run, total cost is C(q)=1000+(q2/10), ATC(q)=(1000/q)+q/10, and marginal cost is MC(q)=2q/10. This implies that ATC=MC at a quantity of 100 and a per unit cost of $20. 1. At what quantity is average total cost minimized? 2. What is the long-run competitive equilibrium price? 3. If market demand is QD=12,000-200P and short-run market supply is QS=300P, what...
