A: Explain what Returns to Scale measures and distinguish between increasing, decreasing and constant Returns to Scale
B: Explain the relationship between Returns to Scale and Long Run Average Cost
C: Explain the relationship between Marginal Product of Labor and Marginal Cost.
D: Explain why a firm's marginal Cost curve represents its Supply Curve.
Answer : Return to scale means that as input has been increased than the output has been increased in that phase.As return to scale means that there has been affected in the input as compared to there output level in an economy
Increasing return to scale means that when output increase at the more proportion as compared to an input level in an economy.As increasing return to scale shows when output increases more as compared to input level.
Constant return to scale means that when output increase at the same proportion as compared to an input level in an economy. As constant return to scale means that when output increases at the same level.
Decreasing return to scale means that when output increases less than as compared to an input level in an economy. As decreasing return to scale means that as when output increases at faster phase.
Answer B : Difference between return to scale and long run average total cost are :
Return to scale means that in which proportion the output has been increased at the input level where as long run average total cost means that when the firm can choose its level of fixed cost as accumulated when firms change production level over time in a particular time period.
Answer C :marginal product is an extra output generated by one additional unit of input such as an additional worker where as marginal cost are additional cost involved in the production. Both are inversely related to each other in systematic manner.
Answer D : The marginal cost curve is a supply curve only in perfect competition firm equates price with marginal cost. This happens only because price is equal to marginal revenue for a perfect competitive fi
