An isoquant is a graphical representation of all the possible combinations of inputs that can be used to produce a given level of output. In other words, an isoquant represents the technical efficiency of a production process. Isoquants are important tools in the field of economics because they help to understand how firms make production decisions and how they can be more efficient.
Input-output analysis is a way of studying the relationship between the inputs used in a production process and the output that is produced. This analysis helps to identify the most cost-effective combination of inputs that can be used to produce a given level of output. It also helps to identify the returns to scale, which is the relationship between the increase in output and the increase in inputs used.
Isoquants are usually plotted on a graph with inputs on the x-axis and outputs on the y-axis. The slope of the isoquant represents the marginal rate of technical substitution (MRTS), which is the rate at which one input can be substituted for another while maintaining the same level of output. The MRTS is important because it determines the cost of production and the cost-minimizing input combination.
The shape of an isoquant is also important. If an isoquant is concave, it means that the MRTS is decreasing as more of one input is used. This indicates that it becomes more costly to substitute one input for another as the quantity of the input increases. On the other hand, if an isoquant is convex, it means that the MRTS is increasing as more of one input is used. This indicates that it becomes less costly to substitute one input for another as the quantity of the input increases.
In summary, input-output analysis and isoquants are important tools in the field of economics because they help to understand how firms make production decisions and how they can be more efficient. Isoquants represent the technical efficiency of a production process and the MRTS helps to determine the cost-minimizing input combination. The shape of the isoquant also provides valuable information about the cost of production.
Isoquant and Isocost Lines (With Diagram)
To remain on the same isoquant or to maintain the same level of output, the positive and negative factor contributions should be equal. Concept of Isoquant 2. Isoquants are convex to the origin This is because of the operation of the principle of diminishing marginal rate of technical substitution. If 2 units of capital could be replaced with one-factor labour, the MRS would be 2 Diminishing marginal rate of substitution If the firm employs 2 L and 40 K. Thus, the firm could choose combination a 18 K + 2 L , combination g 2 K + 18 L or any other combination shown in Table 1. The behavior of the output level when both inputs are increased by the same proportion. In other words for the known quantity of output producer must determine the possible lowest cost factor combination.
Isoquant Curve Analysis: Constrained cost minimization In this case, producers attempt to minimize the cost of production for the given level of output. What is isoquant represent for? In case of perfect complement factors, vertical portion of isoquant shows zero marginal product of capital while horizontal portion shows zero marginal product of labor. However, it does not reveal the degree of substitutability of one factor to another. Hence, the simplified form of isoquants will be as follows: Also note, higher level of isoquant shows higher level of output i. It looks for that factor combination that is on the lowest of the isocost lines. What is the shape of an isoquant curve? Elasticity of Substitution Between Factors We know that MRTS is the slope of the isoquant. As one moves down the isoquant, output remains the same.
Isoquants and Isocost Curves Isoquants are typically drawn along the isocost curves in capital-labor graphs, showing the technological tradeoff between capital and labor in the production function and the declining marginal returns of both inputs. The curve shows the efficient alterÂnative techniques of production or alternative combinations of two factors that can produce a fixed level of output. A new isoquant map can emerge for every level of output. . As such — Such behaviour of an isoquant is based on the principle of diminishing MRTS. Types of Isoquants : The isoquant may assume various shapes depending upon the degree of substitutability of factors.
Isoquant Curve Analysis of Production in Economics
Concept of Isoquant : An isoquant shows various combinations of two factors that will enable a producer to produce a same level of output. An iso-product curve is the graphic representation of an iso-product schedule. What are the different shapes of isoquants? Ridgelines can define as the locus of points of isoquants where the marginal products of the factors are zero. These factors of production are essential to produce any good or service. Nonetheless, point marginal rate of technical substitution of labor for capital at point C is given by slope of tangent at that point. For increasing the production, an organisation needs to increase both inputs proportionately.
The isoquant takes the shape of a right angle. What are isoquants show equilibrium of producer with the help of isoquants and isocost lines? Factors are jointly used in a fixed proportion. Question arises, how could that be possible to produce different level of outputs with same input combination remaining unchanged the production technology? If the change in labour is substituted for the change in capital, then the increase in output due to increase in labour should match with the decrease in output due to decrease in capital. And this would be against the assumption that the isoquant curve is based on. Depending on the degree of substitutability of factors, the production isoquant can take on a variety of shapes. For the sake of simplicity, let us assume that these contours are projected to KL plane.
Joining points K and L by a straight line we get the iso-cost line which shows the combinations of labour and capital that the firm can purchase at given factor prices. Isoquant Curve Analysis: Marginal Rate of Technical Substitution Assume that producer is at point A on the isoquant curve, which produces q 1 units by using the L 1K 1 input combination. Yet, two isoquant curves need not be parallel to each other. In the figure, when OK 1 units of capital were employed, OL 1 units of labor were employed too. The ultimate situation is marginal product of one factor inputs is negative along positively sloped isoquant. The level of output being same, the producer will be indifferent across all the combinations on the isoquant. What are the assumptions of isoquants? Also, every possible combination of inputs is on an isoquant.
While a smooth and convex isoquant is its normal shape, there are a few exceptional shapes as well, two of which are discussed below: Linear Isoquant: This type of isoquant are depicted by a straight line sloping downward from left to right, as shown in Figure-8. Therefore, an isoquant represents a constant quantity of output. The isoquant is known, alternatively, as an equal product curve or a production indifference curve. An isocost line is the producers what a budget line is to a consumer. The indifference curve, on the other hand, measures the optimal ways consumers use goods. History of Political Economy 2012 44 4 : 643—661.
The curve shows that when a firm moves down from point a to point b and it uses one additional unit of labor, the firm can give up four units of capital K and yet remain on the same isoquant at point b. MRTS is the rate at which marginal unit of an input can be substituted for another input making the level of output remain the same. In a two dimensional plane that shows two inputs, say L and K, we can mark various input combinations, which gives a different level of output. Then employing one extra worker can enable it to save 10K. When it comes to technical substitution, this quality is in accordance with the Marginal Rate of Technical Substitution concept MRTS. Knowing how to allocate resources is a concept pertinent to managerial economics. However, marginal rate of technical substitution remains constant if factor inputs are perfect substitutes.
Therefore the output gained from employing more labour must equal the output lost from employing more capital. The term "isoquant" seems to have been coined by Ragnar Frisch, appearing in his notes for lectures on production theory at the University of Oslo in 1928-29. The perfect substitute inputs do not experience decreasing marginal rates of return when they are substituted for each other in the production function. The MRTS diminishes because the two inputs labour and capital are not perfect substitutes. If points H and L are joined on X and Y axes, respectively, then a straight line is obtained, which is called iso-cost line. Let me know by leaving a comment below right now.
Central as it is to economic theory, the creator of the isoquant curve is unknown; it has been attributed to different economists. An iso-cost line shows various possible combinations of the two factors which a producer can procure from the market at the given factor prices from a given amount of outlay. It is a curve that shows the combinations of certain inputs such as Labor L and Capital K that will produce a certain output Q. His background in tax accounting has served as a solid base supporting his current book of business. It implies that the production function is of a variable type of proportion. In this article, we will discuss the Isoquant curve analysis.
