1- From the above table show the three stages of
production?
2- Describe the relationship between marginal and average
product.
3- If the price of output is $10 , and labor’s wage is $350. How
many labors will be hired (L*)?

labor

1.
Increasing return occurs when MPL increases as labor input increases.
Dncreasing return occurs when MPL decreases as labor input increases.
Negative return occurs when MPL becomes negative as labor input increases.
2. Marginal product is the increase in total product as a result of the employment of one more unit of labor input. Average product is the total product divided by the quantity of labor inputs used to produce the total product. In the stage of increasing return MP is above the AP. In the stage of decreasing return AP is above the MP. When the total product reaches maximum, MP becomes zero. When TP decreases, MP becomes negative. The MP curve crosses the AP curve at the maximum of the AP curve.
3. A firm hires the number of workes at the point where Marginal Revenue Product of Labor (MRPL) is equal to the wage rate. From the table it is seen that when wage rate is $350, the firm will hire 4 labors.
