## Explain the difference between Law of diminishing returns and economies of scale This, of course, is the very definition of constant returns to scale. The term returns to scale refers to the change in output as all factor-inputs change by the same proportion in the long run. The logical mistake in the sentence above is that firms maximize profits, the difference between revenues and costs, not just revenues. Further, as the firm expands, it enjoys internal economies of production. The purchase office can place only 10 orders per week …. In LoR, only one factor changes. As you can imagine, these 10 workers keep bumping into one another, quarrelling and making mistakes.

## What is the difference between law of returns and returns to scale? Hence, it is said to be increasing returns to scale. A naive interpretation of these differences in operating income would be that the manager of division A outperformed the manager of division B. Returns to a factor and returns to scale are two important laws of production. No change in the factor-ratio 4 No change in the scale of production Changes in the scale of production. Thus the least cost combination of factors refers to a firm producing the largest volume of output from a given cost and producing a given level of output with the minimum cost when the factors are combined in an optimum manner.

## Microeconomics Problem Set #2 Flashcards Not only this, a firm also enjoys increasing returns to scale due to external economies. The law of diminishing marginal returns states with every additional unit in one , while at least one factor is held constant, the incremental output per unit decreases. Thus production may begin to break down due to poor coordination of resources, which will raise costs, or be prevented by an increase in managers, which will also increase costs. In returns to a facor factor proportion changes but in returns to scale factor proportions remain the same 3. The Slope of the isocost line is equal to the ratio of the price of labour w to the price of capital r i.

## What is the difference between law of returns and returns to scale? On the other hand,Â returns to scaleÂ relate to the long period production function when a firm changes itsÂ scaleÂ of production by changing one or more of itsÂ factors. When factors of production increase from Q to Q 1 more quantity but as a result increase in output, i. The main difference between the two is that for diminishing returns to scale only one input is increased while others are kept constant, and for decreasing returns to scale all inputs are increased at a constant level. The addition of a new machine will lead to a small increase in costs and a large increase in output for a large firm, but a smaller firm would be unable to operate it as much, so the cost to a small firm for each unit produced with the machine will be greater. All these economies help in increasing the returns to scale more than proportionately.

## Microeconomics Problem Set #2 Flashcards The concept of returns to scale are as old as economics itself, although they remained anecdotal and were not carefully defined until perhaps Alfred Marshall 1890: Bk. The firm can specialise more, so that each worker concentrates on one task, which will mean that each worker will need less training, and can learn how to do each task better. It is 150 units at point К instead of 200 units at point P. Thus with specialization, efficiency increases and increasing returns to scale follow. This refers to the Law of Returns to Scale. Therefore, a horizontal isoquant cannot be an equal product curve.

## Microeconomics Problem Set #2 Flashcards Subsidiary industries crop up to help the main industry. Assumptions: This analysis is based on the following assumptions: 1. Explain the difference between Law of diminishing returns and economies of scale 10 These are economic theories that influence cost in the short run and long run respectively. This is known as the stage of diminishing returns. If in order to get equal increases in output, both factors are increased in smaller proportionate units, there are increasing returns to scale.

## Distinguish between returns to a variable factor and returns to scale. Such a situation leads to increasing marginal returns. We see that, in Figure 3. Diminishing ret to a factor occure because of congestion, over crowding etc. By keeping С constant, if the output is to be doubled from 100 to 200 units, then L 3 units of labour will be required. Then there is not diminishing returns. Young 1928 and Nicholas Kaldor 1966 and, indeed, modern Neoclassical endogenous growth theory. Now we take the relation between increasing returns to scale and returns to a variable factor.

## Returns to Scale and Returns to Factor (With Diagram) The only way one might obtain decreasing returns to scale in these circumstances is if there were externalities of some sort, e. Critical Differences to note: 1. Isoquants : An isoquant isoproduct is a curve on which the various combinations of labour and capital show the same output. The fact that marginal products are positive has nothing to do with whether marginal returns are diminishing. However, if there are strong increasing returns to scale, the marginal returns of the variable factor increase instead of diminishing. In both cases, the return consists of special codes inserted into the document to cause the display screen, printer, or other output device to advance t … o the next line.

## Difference Between Diminishing Returns and Diseconomies of Scale The firm can produce 100 units of output at point A on this curve by having a combination of 9 units of capital and 5 units of labour. Thus these external economies are also the cause of increasing returns to scale. Given these assumptions, the point of least-cost combination of factors for a given level of output is where the isoquant curve is tangent to an isocost line. Diseconomies of scale occurs when the per unit cost rises as output is increased. Output 2 nee … ded 2 land. Only one factor varies while all the rest are fixed.
