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. In the early 1990s per capita consumption of soft drinks in the U.S. was 49 gallons, 15 gallons more than the n… Various types of labour services as well as certain raw and processed materials could be placed in this category. Capital must decrease enough to offset the increase in output generated by the increase in labour. If the price of labour rises relative to the price of capital, the firm substi­tutes capital for labour at each level of output, and production process becomes more capital intensive (e.g., tractorisation in agriculture or computerisation in industry). 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 instance, some business call a set of products being produced at the same time a production run. Then, if we add one unit of labour, output would increase by 6 units. Similarly, two nickels will work as well as one dime in operating many vending machines. An isoquant is a locus of points showing all possible combinations of labour and capital phys­ically capable of producing a fixed level of output. More generally, if C is to be totally spent and r is the unit cost, the maximum amount of capital that can be purchased is C/r units; C/r is, therefore, the vertical intercept of the line. Thus, the elasticity of substitution, as defined by Sir John Hicks, is a measure of the relative change in the factor proportion divided by the relative change in factor-price ratio. 13.11 we illustrated one optimizing point for a firm. In the theory of consumer demand we noted that MRS is the ratio of the two marginal utilities. If capital is reduced from 50 to 40 (a decrease of 10 units) labour must be increased by only 5 units (from 15 to 20) in order to keep the level of output unchanged at 100 units. For example, suppose the production function indi­cates that by combining 10 units of capital with 40 units of labour (however measured) we can produce 100 units of output per period. 13.11. What is the definition of production? Production converts inputs into outputs by changing the inputs in some way. 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. 3. Register now There would exist an infinite number of isocost lines, each relating to a different level of cost outlay (expenditure). 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. Since α can be factored out of Eq. Fig. If we were to change the usage of the fixed input, total, average, and marginal product curves would all shift. Thus, as the purchase of labour is increased, the purchase of capital has to fall if total cost remains fixed. The input—output process model provides a mathematical description of production processes and the input—output structure of a company or plant. The human resources function, which recruits and develops the organization’s staff as well as looking after their welfare. If the two are not equal, a firm can reduce cost further by altering the factor proportion. For producers who are not ‘monopsonists’ or ‘oligopsonists’ (i.e., the sole purchaser of, or one of a few purchasers of an input), input prices are taken as given by the mar­ket. In this case the distance along the ray between any two successive isoquants remains unchanged, suggesting a proportionate increase in both inputs and output. This production plan needs to be translated into a master production schedule so as to schedule the items for completion promptly, according to promised delivery dates; to avoid the overloading or under loading of the production facility; and so that production capacity is efficiently utilized and low production costs result. The reason that Castle and Cooke processes and packages Dole pineapple products in Hawaii is more than likely because of low energy costs. Then solving for the MRTS, we get: The M RTS diminishes as the producer moves along an isoquant from left to right. However, it is known to us that the firm will use between 3.75 and 5.6 units of labour. In Fig. Finally, a point will be reached beyond which total output itself will actually fall, indicating a neg­ative marginal product. By using elementary calculus we can summa­rize this relation very quickly. The high­est possible output with the given level of cost is produced by using Lo amount of labour and K0 amount of capital. The important considerations in monitoring the effectiveness of your production plan are shown below: •  Is there a current documentation of production planning and control systems and procedures? The ridge lines OC and OD enclose the area of rational operation, i.e., they delineate the regions in which input combinations are economical. For example, USA’s Pepsi Co. Inc., has long been a leader in the soft drink world. Four hypothetical isoquants are shown. It is the act of creating an output, a good or service which has value and contributes to the utility of individuals. (5). We may accordingly suggest a definition. Moreover, the elasticity of production is negative in stage 3, thus forcing the same conclusion. These internal factors include the company's marketing effort; the product design itself; the strategies to improve customer service; and the quality and price of the product. It is also important to note that combinations other than those on a given isoquant can be used to produce the given level of output; but such com­binations would not reflect the “maximum-amount- of-output” and thus show economic efficiency of the production process. For example, buildings, major pieces of machinery, and manage­rial personnel are inputs that generally cannot be varied quickly. Production may also refer to the goods being produced. Facilities Transforming resources Operation Processes. Production is a process of transforming (converting) inputs (raw-materials) into outputs (finished goods). In economics, a production function gives the technological relation between quantities of physical inputs and quantities of output of goods. If n > 1, we have increasing returns to scale. Here, Fig. Because the marginal product is measured by the slope of the total product curve, marginal product is equal to zero when the slope of the total product curve is zero (i.e., when total product reaches the maximum level). In mathematics, this point is known as the point of inflexion, and it occurs when the second derivative of the total product curve equals zero. These new isocost lines are shown as ZF, Z’F’ and Z” F”. (d) What is the maximum output capability per period? For instance, six hours of labour input and six hours of machine usage may mean six workers each using one machine for one hour (process A), or one worker using one machine for six hours (process B). The end result will be the same as before. It includes all inputs into production, and records materials flow and financial transactions among different units within a company and between the company and the outside market. Here we shall call total output by the name total product or total physical product. False. Eventually, MPL /w would become equal to, MPk/r since MPL rises with decreased use of labour and increased use of capi­tal and MPk falls with increased capital, and de­creased labour. Human reproduction is any form of sexual reproduction resulting in human fertilization.It typically involves sexual intercourse between a man and a woman. So by utilizing the production function equation, the maximum output may be de­termined by substituting 12 for X: We will now consider the more general case of production with two or more variable inputs. 2,000 is spent on capital alone, 20 units of capital may be purchased. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. The resources are natural materials that are included in the production of goods and services. Thus, we observe that the production process is time-specific. In a like manner, isoquant II shows vari­ous combinations of capital and labour that can be used to produce 200 units of output. Capital inputs are measured vertically and labour inputs are measured horizontally (see Fig. It indicates how fac­tor proportions change when output (or expendi­ture) changes, factor prices remaining unchanged. As a firm expands the scale of its operation, oppor­tunities for increased specialization in the use of re­source inputs normally occur. 13.4 this occurs when 2 workers are employed. 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. It is known that maximum output occurs where MP = 0. (8) is said to be homogeneous of degree one. The sum of the quantities of each input used, times the respective input price, gives the minimum cost of producing every level of output. 13.14. If w falls relative to r, the isocost line becomes flatter. This defi­nition surely includes other and equally vital forms of transformation such as that of location, whereby the finished car is moved from the factory to the showroom of the dealer from whom it can be pur­chased. Operations also extend to areas such as Figure 1.2 shows the general transformation process model. We may now turn to the fundamental issue of the properties of the short run production function and the implications of these properties for practicing managers against this backdrop. If the relative factor prices change, the slope of the isocost line must change, If w rises relative to r, the isocost line becomes steeper. Neither can an increase in labour raise output if the stock of capital remains unchanged. True . The ques­tion to be answered about returns to scale is: How much do we have to increase the two inputs, capital and labour, in order to keep on doubling the rate of output from Q0 to Q1, Q2 to Q2, and Q2 to Q3. From our discussion so far we have discovered three different stages of the production process in the short-run. (b) The marginal product of X represents the rate of change of the total product schedule. In Fig. Finally, in traditional economics it is assumed that the techniques of production are ‘given’. Aver­age product will continue to rise so long as marginal product is greater than average product. Firms need to have an aggregate planning or production planning strategy to ensure that there is sufficient capacity to meet the demand forecast and to determine the best plan to meet this demand. 100) and labour receives a wage of Rs. For example, on a product line basis, some firms offer products as a “loss leader”. Suppose for a firm using two inputs K and L, MPL = 5, PL = Rs. 13.7(c). This equation is illustrated in Fig. Work with your best effort and knowledge are main input in production and planning process. We see that the firm can pro­duce 100 units of output by using 10 units of capital and 75 of labour (point D), or 50 units of capital and 15 of labour (point A), or by using any other combination of capital and labour specified by iso­quant I. What specific tool or technique is used to chart in this data? We have noted, in the case of constant returns to scale, if inputs are increased by a given proportion, output rises by the same proportion, that is, αn= a. This concept explains best why firms produce multiple rather than single products. If all inputs are variable, the law of diminishing returns will not apply, and the short run is replaced by a long-run period in which case the decisions to be made by the firm are distinctly different. The law is alternatively called the law of variable pro­portions or, because of the inverse relationship be­tween costs and productivity, and the law of increasing (marginal) op­portunity costs. It forms the foundation for the theory of supply, which, is one of the basic concepts in the deter­mination of prices. 250 per unit (w = Rs. 2. This production plan needs to be translated into a master production schedule so as to schedule the items for completion promptly, according to promised delivery dates; to avoid the overloading or under loading of the production facility; and so that production capacity is efficiently utilized and low production costs result. •  Do actual shipments of orders almost always occur according to schedule? Input – an input is what you what you put into a production process to achieve an into a production process to achieve an output. In reality, the outputs are the start­ing point of the operation inasmuch as they must be considered in the light of the market possibili­ties. In our radio production example, the marginal product of labour ( MPL) can be computed as. (If the firm spend an additional Rs. It was first discovered from the experience of the farmers.
