Answer to Question #40517 in Macroeconomics for ashwini
"Cost function expresses the relationship between the cost and its determinants." Discuss this statement giving examples from any firm of your choice.
Relation between the volume of output and the minimum necessary for its production cost is called cost function. Let's the price of labor, i.e. the amount of money, necessary to pay for theuse of the employee for a certain time , be defined as rL, and the cost of capital - the amount of money paid for the use of the means of production for some time, - rK. Then the total cost to produce a certain number of products will be: TC = rL*L + rK*K.
Given prices of production factors the cost is determined by the value of the minimum required for output volumes of labor and capital, i.e. technology represented by a production function Q = Q (L, K). Therefore, L = L (Q), K = K (Q), and consequently, TC = TC (Q).
The cost of production depends on many factors and these factors vary from one firm to another firm in the same industry or from one industry to another industry. The main determinants of a cost function are:
a) plant size b) output level c) prices of inputs used in production, d) nature of technology e) managerial efficiency
