In economics an isocost line shows all combinations of inputs which cost the same total amount given total cost of inputs. A line joining tangency points of isoquants and isocosts (with input prices held constant) is called the expansion path. Isoquants: An isoquant (equal quantity) is a curve that shows the combinations of certain inputs such as Labor (L) and Capital (K) that will produce a certain. Class 3 isocosts & isoquants. 1. ISOQUANTS Equal Quantity of Production; 2. MEANING OF ISOQUANTS • Isoquants are the curves, which.

This combinations must be the most efficient ones — i. No two factors are perfect substitutes. The marginal physical product per rupee of one factor must be equal to tht of the other factor. The focus of this chapter is on the firm. The absolute value of the slope of the isocost line, with capital plotted vertically and labour plotted horizontally, equals the ratio of unit costs of labour and capital.
Isocost-isoquant analysis | economics |
The slope depends on the prices of factors of production and the amount of money which the firm spends on the factors. This indicates that one factor can be used a little more and other factor a little less, without changing the level of output. If the firm is to maintain the same level of output while reducing capital by one unit, it needs to replace one unit of capital by one unit of labour.
When the amount of money spent by the firm changes, the isocost line may shift but its slope remains the same.
To construct isocost lines we need information about the market prices of the two factors. The slope of iso cost line indicates the ratio of the factor prices. Each curve shows the alternative combinations of labour and capital that would produce 8 and 10 units of output, respectively. We know that the MRTS is equal to the ratio of ispquants marginal products of the two inputs.
So the condition that the Isoquahts be equal to the input cost ratio is equivalent to the condition that the marginal product per dollar is equal for the two inputs. The cost-minimization problem of the usoquants is to choose an input bundle KL feasible for the output level y that costs as little as possible.
Then an outlay of Rs. For example, suppose, the price of labour is Re. If labour were relatively more expensive, the isocost lines would be steeper in Fig.

Isoquant is also called as equal product curve or production indifference curve or constant product curve. Specifically, the point of tangency between any isoquant and an isocost line gives the lowest-cost combination of inputs that can produce the level of output associated with that isoquant.
It is known as the actual rate of factor substitution, the rate at which isocostw firm can substitute labour by capital in the market place.

isocosgs The firm would not operate on the positively sloped portion of an isoquant because it could produce the same level of quantity with less capital and labour. Top 14 Peculiarities of Labour Production Economics.
An isoquant shows what a firm is desirous of producing.
In economics an isocost line shows all combinations of inputs which cost the same total amount. If the price of labour falls the firm could buy more of labour and the line will iskquants away from the origin. We could draw as many isoquants as we like. Least cost input is a combination where the slope of isoquant is equal to the slope of isocost. From the isoquant map, we can generate the total product curve of each input by holding the quantity of the other input constant.
An isoquant is a locus of points showing all the technically efficient ways of combining factors of production to produce a fixed level of output. Retrieved from ” http: So, like the consumer the producer has also to operate under a budget resource annd. A cost-minimizing input bundle is a point on the isoquant for the given y that is on the lowest possible isocost line. Cost minimisation occurs when an isoquant is just tangent to but does not cross an iosquants line.
This condition makes sense: MKTS is, in fact, the ratio of isocostd marginal products of the factors. Suppose, the producer wants to produce six units of output.
In this equationPL is the price of labour and Pk is the price of capital. The minimum-cost points are A, D and E.
Community Community portal Web chat Mailing list. The decision to supply an extra unit depends on the marginal cost of producing that unit. And isoquant must be convex to the isouants. Views Read Edit View history.

The chapter examines the theory of production or how firms organize production i. To find the least cost combination of inputs to produce a given output, we need to construct such equal cost lines or isocost lines.
Isoquantts can see that the shape of isoquant plays an important a role in the production theory as the shape of indifference curve in the consumption theory. If, in the short run, its total output remains fixed due to capacity constraint and if it is a price-taker i.
