A production function expresses the relationship between inputs and outputs in the production process of a firm or industry. It describes the maximum amount of output that can be produced given certain levels of inputs, such as labor, capital, and raw materials.
There are different types of production functions, including the short-run and long-run production functions. The short-run production function assumes that at least one input is fixed while the other inputs can vary. This is useful for analyzing how a firm can adjust its production in the short-term by changing the levels of variable inputs. On the other hand, the long-run production function assumes that all inputs are variable and can be adjusted. This allows a firm to consider the most efficient combination of inputs for producing a certain level of output.
One important concept related to the production function is the law of diminishing returns. This states that as the quantity of one input increases, holding all other inputs constant, the marginal product of that input will eventually decrease. This means that there is a point at which adding more of a particular input will not result in a proportionate increase in output.
The shape of the production function can also be used to determine the technological efficiency of a firm or industry. A firm that is operating at its technological efficiency will have a production function that exhibits constant returns to scale, meaning that increasing all inputs by a certain factor will result in a proportional increase in output. On the other hand, a production function with increasing returns to scale indicates that increasing all inputs will result in a greater than proportional increase in output, while decreasing returns to scale indicates a less than proportional increase in output.
In summary, the production function is a useful tool for analyzing the relationship between inputs and outputs in the production process. It can be used to identify the most efficient combination of inputs and to determine technological efficiency. Understanding the production function is important for firms seeking to maximize their profits and for policymakers looking to improve the efficiency of an industry.
Production Function
Graphically this functional relation appears in the form of a curve. Table 1 show this stage when the workers are increased from four to seven to cultivate the given land, in Figure 2 between EB and FC. In the words of Stigler, The production function is the name given to the relationship between rates of input of productive services and the rate of output of product. Let us understand the algebraic form of production function with the help of an example. The maximum point on the AP curve is E where it coincides with the MP curve. Now if the scale is trebled 3 workers + 6 acres of land , returns become more than three-fold, i.
As a result, costs increase in proportion to the product produced. This is known as returns to scale. Why do returns to scale first increase, become constant, and then diminish? Instead of keeping all variables fixed except one like short-run production functions, in the case of long-run functions, all variables change proportionately. This relationship or the production function governs the level of production. ADVERTISEMENTS: Secondly, the theory of production may be used in the determination of rewards of an input. When the IP curve reaches its maximum point C, the MP curve becomes zero at point F. In fact, it is the scarcity of one factor in relation to other factors which is the root cause of the law of diminishing returns.
Production Function: Transforming Inputs into Output
ADVERTISEMENTS: c The production function may be shown through an algebraic expression in which output is a dependent variable and input, the independent variable. If it is presented mathematically, it is called Production Function. This is evident from the fact that no single commodity can be produced without the help of one of these four factors of production. However, in case of individual production function, they are included in capital factor Raw materials are excluded because they represent a constant relationship with the output at all phases of production. Details related to the derivation of a specific functional form of this production function as well as empirical support for this form of the production function are discussed in more-recently published work. In the figure, this stage starts from the dotted line FC where the MP curve is below the X-axis.
The Theory of Production Function: Concept and Importance
In fact, there may eventually be no effect or a negative effect on output. Stage-II: Law of Diminishing Returns: In between stages I and III is the most important stage of production that of diminishing returns. When more units of the variable factor are applied on such a fixed factor, production increases more than proportionately. As a result, more and more persons are employed on land which is a fixed factor. What will that person contribute to the team? Similarly, the law of diminishing marginal utility in the theory of demand and that of diminishing marginal physical productivity in the theory of distribution are also based on this doctrine.
Therefore, it is in the interest of the producers to produce more. It acts as a collection of different production possibilities of an organization. Depending on the changing nature of variables, production functions can be categorized into two groups. However, in the short-run, it is possible to increase the quantities of one input while keeping the quantities of other inputs constant in order to have more output. In the pizza example, the building is a fixed input.
In the above table, fertilizer is the variable input applied to a fixed price of land with other fixed inputs. Large management creates difficulties of control and rigidities. Linear functions imply that inputs are perfect substitutes in production. The former relates to increasing returns to scale and the latter to decreasing returns to scale. Economists, therefore, use a two-input production function.
It helps to identify the strength of production for a given set of variables. The curve can be concave or convex to the origin depending upon whether the output declines at an increasing rate or at a decreasing rate when more and more doses of an input are used. If the scale of production is increased further, total returns will increase in such a way that the marginal returns become constant. Entrepreneurial control and supervision become lax, and diminishing returns set in. This is the only stage in which production is feasible and profitable. The law of returns to scale is used to express such functions.
What is Production Function? Meaning, Definition, Factors
This point also coincides with point В on the TP curve from where the total product starts a gradual rise. As such, the exercise concerning categorization of the decreasing production function on the basis of the nature of its negative marginal returns to the variable input will have no practical utility. It should be noted that the point of falling output is not the same for total, average and marginal product. A production function shows costs for using inputs and revenues for output sold. The study of short-run production is the subject-matter of the law of diminishing returns which is also called the law of variable proportions.
