## Examples and exercises on isoquants and the marginal rate of technical substitution

The case of capital and labour Any rise of the price of capital implies, according to the isoquants mechanics, a rise in labour employment. An isoquant is convex to the origin because of the diminishing marginal rate of technical substitution. From an empirical economists perspective, observing actual decisions of people and firms, it seems convex curves describe the reality very well. Example- Buildings, major capital equipment and managerial personnel. If different combinations of two factors yielding equal amount of total output are diagrammatically presented in the form of a curve, then such a curve is called on Isoquant or Iso-product curve. Increasing Returns to Scale and Marginal Physical Product of the Variable Factor: Finally, how the marginal physical product of the variable factor behaves when returns to scale are increasing. B, C, D and E produces the same level of output, say 100 units.

## Useful Notes on 3 Most Important Types of Isoquant in Production

Changes in such inputs do have impact on quality of the final product. By experimenting with the , you'll see that any change in price of input results in a new optimal choice. Linear Homogeneous Production Function: Production function can take several forms but a particular form of production function enjoys wide popularity among the economists. The lighter line certainly does not make me twice as happy. It generally happens that there are three phases of increas­ing constant and diminishing returns to scale in a single production function. 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. Please make your own mental and practical experiments with products and production processes you know or can observe.

## How is an Isoquant different from an indifference curve?

Therefore, isoquants are also often called equal product curves production-indifference curves. Isoclines: Isocline is an important concept relating to isoquants and production function. Output in this function was thus manufacturing production. It is therefore concluded that when returns to scale are strongly increas­ing, the marginal returns to a variable factor used with a fixed quantity of the other factor increases. A set of isoquants which represents different levels of output is called ' isoquant map'.

Moreover, because of its simplicity and close approximation to reality, it is widely used in model analysis regarding production, distribution and economic growth. In extreme situation, when the two factors are perfect substitutes of each other, then for all practical purposes, they can be regarded as the same factor. From the foregoing analysis we conclude that if returns to scale are constant the marginal physical product of a variable factor used in combination with a fixed factor will always diminish as more of the variable factor is used. How differently should we have analysed this case? Does it lead to perfectly identical output? Different factors are needed to produce goods. Isocline may be a straight line through the origin or it may be of irregular shape depending on whether production function is homogeneous or non-homogeneous. There are obvious differences: isoquant relates to a firm, indifference curve to a consumer, isoquant relates to output, indifference curve to utility.

These tangents to the successive isoquants are parallel that is, their slope is the same. All the three points A, B and C represent the same output level and lie on the same isoquant. The marginal product of either labour or capital is zero, if its usage is expanded, while the amount of other factor is held constant. The inputs into production are computers, programmers, coffee and pizza. Depending on the price of inputs say for labour , the slope of the isocost curve will be steeper or flatter. An isoquant is a curve showing all the combinations of inputs into production that result in the same output.

## What is Isoquant

Thus, we rule out the following cases in case of isoquants. In economics, an isoquant is a contour line drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs. With perfect substitution the optimal choice lays always on the extreme left or right of the isocost, as you can see clicking the Draw button. Thus, in view of the positive prices that have to be paid for the units of a factor, we rule out the use of the units of a factor that have negative 01 zero marginal products. The points in between, on the downward sloping section, correspond to cases in which the firm runs some of its machines fast and some slowly. Since marginal rate of technical substitution remains the same throughout, the isoquants of perfect substitutes are straight lines, as shown in Fig. Given these two, the isocost line can be drawn.

## Production Functions with Two Variable Factors: Isoquants and Isoclines

An isocline shows the movement from one isoquant to another in an isoquant map. If you change the proportion of the two ingredients, you get a different taste because one made up of 90% milk + 10% coffee is not at all the same as another which is made by 10% milk + 90% coffee. It is thus proved that when returns to scale are constant, or when production function is homogeneous of the first de­gree marginal physical product i. In other words, handcraftmanship and automatization produce usually widely different results e. Is smooth substitution of productive inputs possible? Because of the simple nature of the homogeneous production function of the first degree, the task of the entrepreneur is quite simple and convenient; he requires only to find out just one optimum factor proportions and so long as relative factor prices remain constant, he has not to make any fresh decision regarding factor proportions to be used as he expands his level of production. Considering two factors of production, capital and labour the following table shows various combinations of capital and labour that help a firm to produce 1000 units of a product.

It can be true in discrete jumps, not a continuous function. In reality, this does not happen. You mix the milk and the coffee and you get it. Here, equal addition in one factor requires sacrifice of other factor by same amount every time addition is made. Since, by definition, output remains constant on an isoquant the loss in physical output from a small reduction in capi­tal will be equal to the gain in physical output from a small increment in labour. Thus the is a rectangular hyperbola for every value of y.
