If, however, output increases by more than a, production func­tion is said to exhibit increasing returns to scale. Transportation costs are also likely to be affected by the size of the firm. Suppose for a firm using two inputs K and L, MPL = 5, PL = Rs. Thus, the average product for one unit of labour is 16.5 radios and for two units of labour 21 radios. No output can be produced with zero level of labour (this point has already been noted). Outputs of a Production – Total cost varies directly with output. At point B. This hap­pens when output is 115.6 units and labour input is 5.6 units. This point shows the optimal (least cost) combination of inputs for a fixed level of output. In other words, isoquants, like consumption indifference curves, cannot meet or intersect. Suppose that we start with the following production function: Furthermore, suppose that we multiply each in­put by a constant a. By using elemen­tary calculus we can summarize this relation very quickly. The law of diminishing returns is an empirical law of production. 13.9 are called isocost lines be­cause they show the various combinations of in­puts that may be purchased with a fixed amount of money. The elementary process consists of three components: Input, Conversion, and Output. We may now extend our analysis to cover more than one variable input. In Fig. An isoquant is a locus of points showing all possible combinations of labour and capital phys­ically capable of producing a fixed level of output. In a more general situation, if a fixed amount C is to be spent, the firm can choose among the combinations given by. In Fig. In Fig. In terms of business pol­icy, this suggests that an effective competitive strat­egy would be one emphasizing the development or extension of product lines related to a firm’s well established products. In the short run we study the returns to a fac­tor. Hence the slope of the isoquant through any point becomes, The numerical value of this slope is termed the marginal rate of substitution of the services of factor L for those of factor K and reflects the relative ease of substituting the services of factor L for those of factor K. The relative change in the marginal rate of substitution is called the elasticity of substitution. For example, suppose the estimated production function is. Thus, along a given row output increases, but at a decreasing rate. The expansion path gives the firm its cost structure. The high­est possible output with the given level of cost is produced by using Lo amount of labour and K0 amount of capital. If the constant term a can be factored out of the production function, the function is said to be homo­geneous of degree n. For example, if the production function given in Eq. 13.9. A SIPOC diagram is a tool used by a team to identify all relevant elements of a process improvement project before work begins. A key aspect of the definition is that processes represent interactions that take place among team members. These three points may be proved mathematically. Thus, it is possible to double output by less than doubling of inputs. Because returns to scale is a relative measure – a comparison of the percentage increase in output usage relative to the percentage increase in all inputs – it corresponds. It is because the fixed factor of production is being underutilized in the absence of labour. In any discussion of short run production function, capital is taken to be the fixed input. Therefore, such variation is unlikely to affect short-term production decision. This equation is illustrated in Fig. It is because as additional units of labour are substituted for capi­tal, the marginal product of labour falls. Thus when the second unit of labour is employed, MPL per unit is 25.5 units: Average M PL = ∆Q/∆L = (42.0-16.5)/(2-1)= 25.5.(6). At fixed input prices, r and w for capital and labour, it is possible to purchase with a fixed outlay C, any combination of capital and labour given by the following linear equation: This is the equation for an isocost line whose intercept (C/r) is the amount of capital that may be purchased if no labour is bought and whose slope is the negative of the factor-price ratio (w/r). This, too, has important practical implications for both the production manager, interested in set­ting up the flow of work, and the personnel man­ager, who designs pay scales. Content Guidelines 2. A inputs whose quantity can be changed during the period under consideration is known as a variable input. X = units of variable input employed per production period. If λ< α, the production function exhibits decreasing returns to scale. It helps define a complex project that may not be well scoped. 13.9, w/r = 2.5. output: Production; quantity produced, created, or completed. So output is a function of labour alone. 250 per unit (w = Rs. It, therefore, follows that no matter what the ratio of input prices is, the firm uses the same combination of inputs to produce each given level of output. In Fig. The elasticity of substitution is also important in an analysis of the relative shares of labour and capital in the national product (income). The first unit of labour results in 16.5 radios being produced, and the second unit of labour (when combined with the first unit and the fixed resources) results in 42 radios being produced and so on. 13.3 graphically illustrates the behaviour of the average product of labour for the radio production function. 3. To answer this question, we need the concept of returns to scale. It can be defined as the total product divided by the quantity of the variable input (i.e., the num­ber of workers) employed. Is the firm optimizing the use of its resources? If the price of capital rises relative to the price of labour, the firm substitutes labour for capital (e.g., manual operation of petro pumps in place of power-driven machines). Any cost out­lay below that, for example that represented by KL, is not feasible since it is impossible to produce out­put Q0 with these factor combinations. The cognitive aspect of schooling is discussed here and is restricted to those aspects readily measured by achievement tests. In panel (a) of Fig. However, such production would simply ‘waste’ economic resources. This means that if labour remains at a given level while capital is increased, no more output can be produced. We have derived the expansion path under only one set of input prices. If we were to change the usage of the fixed input, total, average, and marginal product curves would all shift. Thus he has to make either of two input choice decisions: 1. In the radio example, both average product and the marginal product concept refer to labour (L), the only variable factor of production. Because all inputs have a cost, the long-run con­cept of returns to scale has significant implications for the behaviour of the long-run cost curve, and these results are shown in panels (a’), (b’), (c’) in Fig. In this case MRTS is 10/35, indicat­ing that for each unit of labour added capital can be decreased by 2/7 of a unit. Various types of labour services as well as certain raw and processed materials could be placed in this category. Suppose that, at a point on the isoquant, the marginal prod­uct of capital (MPk) is 3 and the marginal product of labour (MPL) is 6. This is called the input (factor) sub­stitution effect. It is also an economic relation indicating the maximum amount of output that can be obtained from a fixed amount of resources (inputs). When 3.75 units of labour are combined with the fixed factors of production, the elasticity of production is equal to exactly 1, indicating that production is increasing at a rate at which labour usage is increas­ing. The implication is that for our two-input case a firm attains the highest level of out­put when. So the firm would be better off by using less labour and more capital. (a) Graphically illustrate the production func­tion, indicating the following: (b) Determine the equation for the MP and AP of the variable factor. For example, 4 machines and 2 workers produce 50 units of output. Thus, we observe that the production process is time-specific. This is because the fixed factors of production cannot be utilized ef­ficiently without sufficient use of the labour input. Clearly, a movement from A to B would result in a reduction of both L and K. And since inputs are to be paid, an entrepreneur would prefer point B to point A, as he is assumed to behave rationally. (If the firm spend an additional Rs. , 2010, p9) Fig1. In stage 3 total product is itself falling. Table 13.1 and Fig. If the two are not equal, a firm can reduce cost further by altering the factor proportion. Therefore, continuous increase in the use of the vari­able factor throughout stage 1 is warranted. Since the ratio w/r increase, the iso­cost lines become steeper. The most basic form of the short run production function was presented in Equation (1) or (1)’ and contains one variable input. Thus, if a firm, say a computer manufacturer is utilizing the most up-to-date technology, and if this technology is modified, from say transistors to silicon chips, then the production process and the production function must undergo change accordingly. It results from a change in factor prices. It is argued that education production function studies should rely less on large-scale survey data; and … Economies of scope assume added significance of late because they permit a firm to translate supe­rior skill or productive capability in a given prod­uct line into unique advantages in the production of complementary products. 1,500. A wide variety of inputs are transformed so that they give out a set of outputs. A SIPOC (Supplier-Input-process-Output-Customer) diagram is used to identify all the important key elements of a process before the work begins. In traditional economics, the term ‘production’ is used in a broad sense. However, 10 units of capital and 40 units of labour could produce less than 100 units of output if they are used inefficiently, but they can produce no more. That is, when capital is abundant rel­ative to labour, the firm can discharge 10 units of capital but must substitute only 5 units of labour in order to obtain the same level of output. 13.2 is a graphic repre­sentation of equation (2) which is the short-run pro­duction function for radios. In Fig. Thus, the marginal product of the variable factor (labour) may be defined as the rate of change in total output associated with the employment of one additional unit of the variable factor. Any factor combination above that represented by K’L’ are not considered because the firm seeks to produce the de­sired output at least cost. In our radio production example, the marginal product of labour ( MPL) can be computed as. But, it should be clear that change in relative input prices change the expan­sion path and hence the cost structure. While the physical and mental human effort spent in producing goods are services is labour. In like manner, increasing returns in panel (a) results in total costs in panel (a’) growing at a decreasing rate, that is, continuously declining cost per unit. Thus, it logically follows that marginal prod­uct must be equal to average product when the latter reaches its maximum, i.e., when it is neither increas­ing nor falling. And this rule is applicable to variable resource allocation problems. 13.15 highlights the nature of the inverse relationship between produc­tivity and cost. The isoquant shows the desire of the producer. In the case of two variable inputs, changing the use of one input is likely to cause a shift in the marginal and average product curves of the other input. The manager can choose from among different combinations of capital (K) and labour (L) to pro­duce a given level of output. Capital is the man-made means of production like machinery, factory and building etc., and the entrepreneur coordinates the inputs and takes risk of business. A comprehensive introduction to Input Process Output tables. (5). Here we look at a producer who is a competitor in the input market facing given market-determined input prices; so we treat the input prices as fixed. Two forces work further to cause marginal product of labour to a fall: (1) Less capital causes a downward shift of the marginal product of labour curve, and. There are two basic processes for converting inputs into outputs. The process of production is concerned with transforming a set range of inputs, depending on the product, into those outputs that are required by the market (demand). 2. These two items might be perfect substitutes for each other in the generation of heat. Inputs of a Production – There are wide variety of inputs used by the firms, like various row materials, labour services of different kinds, machine tools, buildings etc. (d) What is the maximum output capability per period? Such a situation is illustrated in Fig. We see that isoquants for perfect complements are Z-shaped. If labour is limited to 2 units, no matter how much capital is added beyond 5 units, only 100 units of output can be produced. 13.3. The purpose of this paper is to discuss some of the problems and prospects of applying production function or input-output analysis to the process of schooling. Raw material, labour, power, transportation etc., are examples of variable inputs, whose quantity can often be increased are decreased on short notice. Fig. (7) is multiplied by the factor α, we obtain. All the relationships between cost and its individual determinants, the cost-output relationship is the most important one. were w and r are, respectively the prices of labour (PL) and capital (PK). Fig. 3. Here α and αn represent increases in the scale of operation and level of output, respectively. The definition of production function does not preclude the possibility of negative RTS. When L equals 2, however, the marginal product of labour (shown in Table 13.1) is 28 units (or aver­age MPL = 2.8 units). In this article we will discuss about the Theoretically Analysis of the Production Process. In this context, Pappas and Brigham have com­mented that “the economies of scope concept plays an important role in managerial decision making be­cause it offers a useful means for evaluating the po­tential of current and prospective lines of business. If combinations A or B are chosen, at the cost outlay represented by K”L”, the producer can reduce costs by moving along Q0 to point E. Point E shows the optimal resource combination, K0units of capital and L0 units of labour. We can analyse the equilibrium condition in an alternative way. An intuitive understanding of the concepts of increasing, constant and decreasing returns to scale can be developed by looking at Fig. There are various variables that might account for the phenomenon of increasing returns to scale. Then returns to scale (RTS) would become negative, as at point A of Fig. Economist’s emphasis on this relationship is reasonable because it is subject to faster and more frequent changes. 13.11. A firm reaches equilib­rium and thus minimizes cost when the lowest pos­sible isocost line (whose slope is the factor-price ra­tio) is tangent to the isoquant (whose slope is MRTS). a production function that assumes that inputs are relatively substitutable is called a ___. To ensure this, the profit-maximizing firm has to choose that input combination for which the marginal product divided by input price is the same for all inputs used. In our example, the production decision maker should in­crease the use of labour up to at least 3.75 units. 3. While discussing the nature of long-run produc­tion, Samuel Webb has drawn a distinction between substitute and complementary inputs. and if the increase is substantial even fixed inputs like plant and equipment, and managerial staff may have to be increased. Then, if we add one unit of labour, output would increase by 6 units. Various inputs are normally used in production. Recall that the isoquant shows the desired rate of factor substitution and the isocost line the actual rate of factor substitution. Production managers of the Metal Box Co. esti­mate that their production process is currently char­acterised by the following short-run production function: where Q = tonnes of boxes produced per production period and. On the basis of such classification of inputs, economists draw a distinction between the short run and the long-run. The area of economics that focuses on production is referred to as production theory, which in many respects is similar to the consumption theory in economics. Finally, if Q1 is less than 200 units (say, 180) the production function is said to exhibit decreasing returns to scale. PRODUCTION FUNCTION: INPUT-OUTPUT RELATIONSHIP. It is an easy way to define a project that may seem complex and is not well scoped. It has five components in its own right. Finally, a point will be reached beyond which total output itself will actually fall, indicating a neg­ative marginal product. The direction of substi­tution depends upon the nature and direction of the relative change in factor prices. 13.7(c) repre­sents the various combinations of the two variable inputs that can be used to produce the specified level of output. If output increases exactly by the same proportion, the production function is said to exhibit constant returns to scale. The implication is that the profit-oriented will not will surely seek to expand production all the way through stage 1. That requires knowledge; we must know how to use the things we find in nature before they become resources. Production is a process in which economic resources or inputs (com­posed of natural resources like land, labour and cap­ital equipment) are combined by entrepreneurs to create economic goods and services (also referred to as outputs or products). This is because increased production requires increased use of raw materials, labour, etc. Panel (c) shows decreasing returns to scale. 250). There would exist an infinite number of isocost lines, each relating to a different level of cost outlay (expenditure). So the production process has to be organized in the most efficient manner. The input data of the sales and operations planningin the pharmaceutical industry are the sales forecasts grouped by product families. An important point to note in this context is that when two units of labour are employed, the aver­age product of labour increases. Alternatively, consider the production function given below. Suppose we start with a given capital/labour ratio of K1/L1, which is the same in all the three panels. 1, and produce the same level of output but at a reduced cost. In the above example, both average product and the marginal product concepts refer to labour (L), the only variable factor of pro­duction. In the short run, it is assumed that some factors (such as capital or plant size) remain fixed and others are variable. The informa­tion in this column is illustrated graphically in Fig. Thus the equation becomes 1500 = 100A’ + 250L . 13.7(c), it- is clear that 100 units of output could be produced using more than 10 units of capital and more than 75 units of labour. The only decision to be made by manage­ment in case of the radio production function was to determine the appropriate quantum of labour to be used in the production process. The first is that they are found in nature—that no human effort has been used to make or alter them. The isocost line is, in fact, the producer’s budget line. Then solving for the MRTS, we get: The M RTS diminishes as the producer moves along an isoquant from left to right. The major difference between your two procedures is the type of inputs. 5, MPK = 40, and PK = Rs. It could continue to do this until the above inequal­ity is converted into an equality. Input Output Model of Production System: It is one of the basic models of the production system. Simply put, production involves the transfor­mation of inputs – such as capital equipment, labour, and land – into output of goods or services. A complex concept, the elasticity of substitu­tion, is a property of production function. The utilized amounts of the various inputs determine the quantity of output according to the relationship called the production function. The returns to scale may be treated more an­alytically by expressing the production relation in functional form as, Suppose we increase the inputs by a constant proportion (say, a) and output gets multiplied by αn. Input data. Whatever output a firm chooses to produce, the production manager is desirous of producing it at the lowest possible cost. Or, faced with spec­ified input prices, it can choose from among many combinations of K and L that would lead to a fixed level of cost, i.e., expenditure. Similarly, if Rs. Trans­portation costs do not double when the size of the market gets doubled. This does not necessarily mean that the second unit of labour is more efficient than the first unit. 2. Choose the input combination that leads to the lowest cost of producing a fixed level of output (i.e., cost minimization subject to output constraint). Put differently, production at least cost requires that the MRTS of capital for labour be equal to the ratio of the price of labour to the price of capital. The sum of the quantities of each input used, times the respective input price, gives the minimum cost of producing every level of output. Panel (b) illustrate the case of constant returns to scale. The inputs are the same in each case, but for the produc­tion manager, it makes a lot of difference whether process A or B is selected and used. Thus we get. Capital inputs are measured vertically and labour inputs are measured horizontally (see Fig. The distinc­tion is not based on any time period but is made on the basis of the possibility of factor substitution. The expansion path shows the way in which fac­tor proportions change in response to output changes, with the factor-price ratio remaining unchanged. (b) The marginal product of X represents the rate of change of the total product schedule. However, we know that there exists an optimal com­bination for every level of output the firm might choose to produce, and the proportions in which the inputs are combined need not necessarily be the same for all levels of output. In comparison with inputs and outputs, group processes are often more difficult to measure, because a thorough understanding of what groups are d… In some pro­duction functions the elasticity of substitution is as­sumed to be unity; many empirical studies (such as those made by Cobb and Douglas) have also shown values close to unity. Disclaimer Copyright, Share Your Knowledge Let us suppose that we have collected necessary information on the relationship between the number of radios produced per month and the labour (L) utilized on a monthly basis as noted in Table 13.1. The point at which average product reaches its maximum is the point of maximum production efficiency in the short run. (7), and a in Eq. Learn how to effectively model the important processing going on in your system. Let us consider an increase in the usage of all inputs by a proportion a. The level of output, Q, depends upon the use of the two inputs, L and K. Since output Q is the same at all points on an isoquant, ∆Q is zero for any change in L and K along an isoquant. Where there are no losses and stocks (opening or closing), Total value of the output = Total expenditure incurred in the process Output units = input units By following the same logic it is pos­sible to establish that if the inequality is reversed, such as the case at point A, the firm would con­tinue to substitute labour for capital until the equal­ity holds. 13.2 show that at the early stage of the production pro­cess output increases at an increasing rate as the first few units of labour are added; at the second stage it continues to increase but at a decreasing rate as more and more workers are employed. Thus, in general, when L and K are allowed to vary marginally, the change in Q resulting from the change in the two inputs is the marginal product of L times the amount of change in L plus the marginal product of K times its change. If we are interested in finding out the level of labour usage that maximizes average product, we have to take the first derivative of equation (3), set it equal to zero, and solve as follows: Thus, the average product of labour is maxi­mum at 3.75 units of labour. Economies of scope exist for multiple products when the cost of joint production is less than the cost of producing each output separately. 250, 2 ½ units of capital have to be sacrificed; if 2 units of labour are bought, 5 units of capital must be given up and so on. However, each capital-labour combination can be on only one,iso­quant. It is also known as production indifference curve. Maximum,” output is being achieved when twelve men are employed. In a like manner, an additional worker where there is only one shovel at point C can produce no more holes, assuming shovels are essential for digging and that a worker can work continuously without relief. In fact, the key concept in the theory of production is the produc­tion function, which is a technical relation showing how inputs are converted into output. For example, if we were to double both K and L inputs, output would surely increase but we do not know by how much. These new isocost lines are shown as ZF, Z’F’ and Z” F”. TOS4. Consider oil. Firms can also take advan­tage of large-scale equipment due to indivisibility of factors. To accomplish this objec­tive, the production process must not only be tech­nically efficient but economically efficient, as well. The business firm is basically a producing unit it is a technical unit in which inputs are converted into output for sale to consumers, other firms and various government departments. Rather than each worker making a complete pin, increased output allows workers to divide up tasks into separate activities, such as drawing the wire and forming the pin. = — ( —1 ) /1/2 = 2 ) leads to a period of un­der!
