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. An isoquant is a contour line drawn through the set of points at which the same quantity of Isoquants are typically drawn along with isocost curves in capital- labor graphs, showing the technological tradeoff between capital and labor in the . 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.

It is known as the actual rate of factor substitution, the rate at which the firm can substitute labour by capital in the market place.

B; with a level of production Q3, input X and input Y can only be combined efficiently in the certain ratio occurring at the kink in the isoquant. 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.

See full list of related question in B. This equals the ratio of marginal productivity of two inputs. When the amount of money spent by the firm changes, the isocost line may shift but its slope remains the same. Isoquants are typically drawn as being convex to the origin because of the assumed substitutability of inputs. Ridge lines joins points isoqusnts the various isoquants where the isoquants have zero slope and thus zero MRTSlk.

Determination of factor prices in a competitive market: An isoquant derived from quantity and the Greek word iso, meaning equal 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.

Thus at a point of equilibrium marginal physical isoocosts of the two factors must be equal the ratio of their prices. See all related question in economics. For the two production inputs labour and isoqquants, with fixed unit costs of the inputs, the equation of the isocost line is. Also called pay-as-you-earn scheme, advance tax is the income tax payabl Increasing returns to scale can be obtained only upto a point. Equivalently, it gives the maximum level of output that can be produced for a given total cost of inputs.

Isocost – Wikipedia

An isoquant is a locus of points showing all the technically efficient ways of combining factors of production to produce a fixed level of isouqants. Each such point shows the equilibrium factor combination for maximising output subject to cost constraint, i. A line joining tangency points of isoquants and isocosts with input prices held constant is called the expansion path.

An isocost line is a locus of points showing the alternative combinations of factors that can be purchased with a fixed amount of money. We 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. We may now speak a few words about the slopes of isoquant and an isocost line.

All these and other various combinations are shown in Fig. Top 14 Peculiarities of Labour Production Economics.

This indicates that one factor can be used a little more and other factor a little less, without changing the level of output.

Least cost input is a combination where the slope of isoquant is equal to the slope of isocost. If the distance between those isoquants increases as output increases, izocosts firm’s production function is exhibiting decreasing returns to scale; doubling both inputs will result in placement on an isoquant with less than double the output of the previous isoquant.

This page was last modified on 16 Aprilat By moving from F to E or from G to E, the producer attains the same output level at a lower cost. An isoquant shows what a firm is desirous of producing. 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.

Also, every possible combination of inputs is ans an isoquant.

Explain a firm’s equilibrium with the help of isoquants and isocost line.

Isoquants, abbreviated as IQs, possess the same properties as those of the indifference curves. The firm can achieve maximum profits by choosing that combination of factors which will cost it the least.
