Its slope is given by the ratio of the prices of the two factors. The point where the isocost line is tangent to an isoquant represents the least cost combination of the two factors for producing a given output. The least cost factor combination can be determined by imposing the isoquant map on isocost line. It is possible because the axes in both maps represent the same input variable the points of tangency a, b and c on each of the isoquant curves represent the.

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. For the two production inputs labour and capital, with fixed unit costs of the inputs, the equation of the isocost line is. It is a graphical representation of various combinations of inputs say labour l and capital k which give an equal level of output per unit of. 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. That is, the 1isoquant is the set of all pairs of numbers whose smallest member. As nouns the difference between isoquant and isocost is that isoquant is economics a line of equal or constant economic production on a graph, chart or map while isocost is economics a curve that represents a combination of various inputs that cost the same. Isocosts and isoquants can show the optimal combination of factors of production to produce the maximum output at minimum cost. In this example, we have one isocost and three isoquants. This can observed by superimposing the isocosts on isoproduct curve 7 8. Economics of input and product substitution output is identical along an isoquant output is.

Scribd is the worlds largest social reading and publishing site. The isocost on the right represents a higher outlay. The slope of an isoquant is equal to that of an isocost is the place of the point of cost of production. In economics an isocost line shows all combinations of inputs which cost the same total amount.
In it we learned that a linear equation, called an isocost line can be used to model the total cost of hiring two variable inputs. If all points of tangency like lmn are joined by a line, it is known as an output factor curve or leastoutlay curve or the expansion path of a firm. The iso cost line represents all these combinations. A line joining tangency points of isoquants and isocosts with input prices held constant is called the expansion path.
