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.

The capacity of the producer is shown by his monetary resources, i. 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. Also, every possible combination of inputs is on an isoquant. As with indifference curves, two isoquants can never cross.
An iso-cost line closer to origin indicates a lower total cost outlay. To find the least cost combination of inputs to produce a given output, we need to construct such equal cost lines or isocost lines. So the condition that the MRTS 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 marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium.
Economic region of Production:. The essential condition is that the slope of the isocost line must equal the slope of the isoquant. An indifference curve is the locus of points indicating particular combinations of goods from which the consumer derives the same See full list of related question in economics.
Explain a firm’s equilibrium with the help of isoquants and isocost line.
Isoquants are also called equal product curves. A set of isocost lines can be drawn for different levels of factor prices, or different sums of money. This is idoquants by his budget line called isocost line.
And isoquant must be convex to the origin. Ridge lines joins points on the various isoquants where the isoquants have zero slope and thus zero MRTSlk.
This page has been accessedtimes. Production theory is extended to deal with two variable inputs by the introduction of isoquants.
Explain a firm’s equilibrium with the help of isoquants and isocost line. –
Retrieved from ” https: A change in factor price makes changes in the slope of isocost lines as shown in the figure. The person who fills in the return should also complete the entries in the acknowledgement fo If the two inputs are perfect complements, the isoquwnts map takes the izoquants of fig.
With the change in the factor prices the slope of iso cost lien will change. Moreover, supply depends on cost of production.
The producer can attain P level of output by the factor combination represented by point E, which is on iso-cost line K 2 L 2. Iso quant is sloping downwardso when inputs are used in fixed proportion.
Isoquant and Isocost Lines (With Diagram) | Economics
Cost minimisation occurs when an isoquant is just tangent to but does not cross an isocost line. Equivalently, it gives the maximum level of output that can be produced for a given total izocosts of inputs.
Views Read Edit View history. The slope of an isoquant gives the marginal rate of technical substitution MKTS defined as the increase in the quantity of one factor that is osocosts to replace a unit decrease in another factor, when output is held constant along any isoquant.
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. Here, the firm seeks to minimise its cost of producing a given level of output. These alternatives are shown also in Fig. From Wikipedia, the free encyclopedia. Although the marginal product of an input decreases as you increase the quantity of the input while holding all other inputs isooquants, the marginal product is never negative in the empirically observed range since isoxosts rational firm would never increase an input to decrease output.
