Laws of Returns: The Isoquant

isoquants and their properties

Instead, it might be possible that labour cannot substitute in any way a piece of machine, so there will be no change at all in techology used for a wide range of small price increases. In general, convexity of isoquants implies that it becomes progressively more difficult or harder to v substitute one factor for another as we move along an isoquant and increase the use of one factor substituting the other factor. These combinations may be plotted as points on a two dimensional plane, often called the input space. Experiment with different prices of inputs and you shall see that the solution is always there, jumping from one extreme to the other depending on which is the cheapest input. After a point, there is a phase of constant returns to scale where output increases in the same proportions as inputs.

isoquants and their properties

Is their work mainly oriented to cost minimization obtained by substituting given inputs? One example is when iron rusts or oxidizes it forms iron oxide, or rust. The slope of the isocost line is the ratio of prices of labour and capital i. We arrive at the conclusion that a firm will find it profitable to produce only in the second stage of the law of variable proportions for it will be uneconomical to produce in the regions to the left or right of the ridge lines which form the first stage and the third stage of the law respectively. Interspacing between them is least at the ends and maximum in the middle. In reality, this does not happen.

isoquants and their properties

Homogeneous production function of the first degree, which, as said above, implies constant returns to scale, has been actually found in agriculture as well as in many manufacturing industries. Thus, only point E can be an op­timal point. Thus it means equal quantity or equal product. Labour can be substituted for capital and ice versa. An isoquants shows all those combinations of factors which produce same level of output. The downward sloping iso-product curve can be explained with the help of the following figure: The Fig.

isoquants and their properties

The iso quant closer to the origin indicates a lower level of output. Isoclines: Isocline is an important concept relating to isoquants and production function. Thus with specialization, efficiency increases and increasing returns to scale follow. The interest on a judgment lien in Massachusetts is 12%. It is therefore concluded that when returns to scale are strongly increas­ing, the marginal returns to a variable factor used with a fixed quantity of the other factor increases.

Isoquants: Meaning, Assumptions and Properties

isoquants and their properties

These properties follow from some assumptions. The prices of units of labour w and that of capital r are given and constant. When we increase labour, we have to decrease capital to produce a given level of output. This would be an example of in the bounded rational tradition. To start with, factor combination A consisting of 1 unit of labour and 12 units of capital produces the given 100 units of output. Then the output must increase. But the reverse is not true.

Trade journals, research and training centres appear which help in increasing the productive efficiency of the firms. If the picture above describes my utility as a consumer: the light blue line obviously makes me more happy than the darker line. Output Maximisation subject to Cost Constraint: A rational producer, whose ob­jective is output maximisation subject to cost constraint, will always try to reach the highest attainable isoquant permitted by the isocost line. Usually they are found different and, therefore, isoquants may not be parallel as shown in Fig. The Laws of Returns to Scale: Production Function with two variable inputs The laws of returns to scale can also be elucidated in stipulations of the Isoquant approach. Work can be divided into small tasks and workers can be concentrated to narrower range of processes. Subsidiary industries crop up to help the main industry.

isoquants and their properties

Isoquants are typically combined with lines in order to solve a cost-minimization problem for given level of output. When a large number of firms are concentrated at one place, skilled labour, credit and transport facilities are easily available. Thus, the two inputs can be substituted for one another to maintain a constant level of output. Further, Cobb-Douglas production function is also frequently used to estimate output elasticities of labour and capital. This type of isoquant is also called 'Leontief isoquant' after Leontief, who invented the input-output ananlysis. Slope of iso cost line With the change in the factor prices the slope of iso cost lien will change.

3 Most Important Properties of Isoquants

isoquants and their properties

The isoquant is a continuous function, so it implies that it is possible to reduce say 1% of labour time if capital - however measured - is increased by x%. Thirdly, as shown in Fig. Both the situations are impossibilities because nothing can be produced either with only labour or only capital. Secondly, isoquants cannot meet or intersect one another. It cannot have a po … sitive slope.
