Isocost-isoquant analysis: theory of production: The production function: a figure known as an isoquant diagram (Figure 1). In the graph, goldsmith-hours per. Finding the conditions for cost minimization is a little bit different for Isoquant and Isocost lines. Instead of finding the optimal quantity level for a. 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 focus of this chapter isquant on the firm. 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 required to replace a unit decrease in another factor, when output is held constant along any isoquant.

Therefore, the only way isoquanh maximise profit is to minimise cost. Assumptions The principle of least-cost combination rests on the following assumptions: The firm can achieve maximum profits by choosing that combination of factors which will cost it the least. A cost-minimizing input bundle is a point on the isoquant for the given y that is on the lowest possible isocost line.

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.

Other product and company names shown may be trademarks of their respective owners. When this happens the ratio of the prices of factors is the same as the ratio of their marginal products. Isoquants indicate various possibilities of combining two inputs. Likewise, the isocost line will shift to the right if the outlay of the firm increases.

For the convenience of the students, we can state them as follows. A set of isocost lines can be drawn for different levels of factor prices, or different sums of money.

Isoquant and Isocost Lines (With Diagram) | Economics

This combinations must be the most efficient ones — i. Each such point shows the equilibrium factor combination for maximising output subject to cost constraint, i. Retrieved from ” http: If the isoquants are smooth and convex to the origin and the cost-minimizing input bundle involves a positive amount of each input, then this bundle satisfies the following two conditions:. It is also known as the desired rate of factor substitution, i.

The isocost line is combined with the isoquant map to determine the optimal production point at any given level of output. Javascript software libraries such as jQuery isouant loaded at endpoints on the googleapis.


When the amount isoqyant money spent by the firm changes, the isocost line may shift but its slope remains the same. These lines are straight lines because factor prices are constant and they have a negative slope equal to the factor-price ratio, i.

The cost function for a firm with two variable inputs

Navigation menu Personal tools Isoquan in Request account. The marginal physical product per rupee of one factor must be equal to tht of the other factor.

Ridge lines joins points on the various isoquants where the isoquants have zero slope and thus zero MRTSlk.

In economics an isocost line shows all combinations of inputs which cost the same total amount. Least cost input is a combination where the slope of isoquant is equal to the slope of isocost. Iso quants are equal revenue lines. Equivalently, it gives the maximum level of output that can be produced for a given total cost of inputs. This condition makes sense: This is used to provide traffic data and reports to the authors of articles on the HubPages Service.

A change in factor price makes changes in the slope of isocost lines as shown in the figure.
