Two Factors of Production: Only two factors are used to produce a commodity. No Isoquant can Touch Either Axis: If an isoquant touches X-axis, it would mean that the product is being produced with the help of labour alone without using capital at all. An isocost line is a locus of points showing the alternative combinations of factors that can be purchased with a fixed amount of money. It is also known as the equal product curve. Two Iso-Product Curves Never Cut Each Other: As two indifference curves cannot cut each other, two iso-product curves cannot cut each other. Thus isoquant curve is that curve which shows the different possible combinations of two factor inputs yielding the same amount of output. As shown in the above diagram, the short-run production function puts the quantity of labor L on the horizontal axis since it's the independent variable and the quantity of output q on the vertical axis since it's the dependent variable.

The level of output being a physical magnitude is measurable. In short, both the concepts of returns to scale and returns to a factor change in factor proportions can be explained by using the technique of Isoquants. All these economies help in increasing the returns to scale more than proportionately. That is, for every real number we put as x, we will get a value for f x. It implies that the marginal product of labour continues to decline with the employment of larger quantities to it. The perfect substitute inputs do not experience decreasing marginal rates of return when they are substituted for each other in the production function.

But they intersect each other at point A. In the long run, there are often a number of different ways to get a particular quantity of output. A higher indifference curve represents a higher level of satisfaction but we cannot say by how much the satisfaction is more or less. We can only say the higher curve is preferred to the lower one. When the two factors are perfect substitutes of each other, then each of them can be used equally well in place of the other. Hence isoquants are straight lines.

Function returns a value, procedure does not unless you are using c , then everything is a function. Suppose, the producer wants to produce six units of output. Returns to Scale and Marginal Returns to a Variable Factor Constant Returns to Scale and Returns to a Variable Factor: We now turn to study the relationship between returns to scale and marginal returns to a variable factor. Output elasticity of a factor shows the percentage change in output as result of a given percentage change in the quantity of a factor. If the isoquant slopes upward to the right, it implies that both capital and labour increase but they produce the same output. A function describes a relation between several variables. Isoquants for a technology in which there are two possible techniques Consider a technology in which there are two possible techniques.

Since we know the truth is beautiful, the ugly math cannot be true and we will stick to the nice convex curves that have nice math to solve it. Isoquant curves are also known as Equal product or Iso-product or Production Indifference Curves. Macros are essentially shorthand representations of arbitrary sections of the source code, which makes the source code succinct, while its the macro template's expansion replaces each of its presence prior to compilation. Note that tangents at points a 2, b 2 and c 3 to isoquants Q 1 Q 2 and Q 3 are relatively flatter as compared to those at a 1, b 3 and Two things must be noted in respect of isoclines of a homogeneous production function. It can buy you the finest clothes, but not class and elegance because these attributes are a matter of how one carries himself and not simply wearing the most expensive clothes.

This graph is used as a metric for the influence that the inputs have on the level of output or production that can be obtained. How can the same factor combination produce two different levels of output, technique of production remaining unchanged? Indifference curve provides no information regarding the economic and uneconomic region of consumption. Properties of Iso-Product Curves : The properties of Iso-product curves are summarized below: 1. The economic region of production for a homogenous production function e. I could assign 2,72 and 3,14 to the lines and they could still represent the same preferences and obviously 3,14 is not twice 2,72. Iso-Product Schedule : Let us suppose that there are two factor inputs—labour and capital.

Obviously the light blue combinations - feeding the programmers more pizza and more coffee - give me more output; and the output is exactly twice as large as the dark blue combinations. The first condition is that the slope of the isocost line must equal the slope of the isoquant curve. In the case of a price difference, there would be no demand for the more expensive good. Therefore, the units that are appropriate for the quantity of capital will depend on the specific business and production function. We have seen that there are diminishing returns to a factor because of the fact that different factors are imperfect substitutes of each other in the production of a good.

The lighter line certainly does not make me twice as happy. . Conclusion: It can be concluded from the above analysis that under a homogeneous production function when a fixed factor is combined with a variable factor, the marginal returns of the variable factor diminish when there are constant, diminishing and increasing returns to scale. Assumptions: This analysis is based on the following assumptions: 1. This isoquant, together with the is shown in the following figure. However, there are certain differences between isoquants and indifference curves. In the up dotted portion, more capital and in the lower dotted portion more labour than necessary is employed.
