## What are the causes of increasing returns to a variable factor?

There are three important reasons for the operation of increasing returns to a factor:

• Better Utilization of the Fixed Factor: In the first phase, the supply of the fixed factor (say, land) is too large, whereas variable factors are too few.
• Increased Efficiency of Variable Factor:
• Indivisibility of Fixed Factor:

## Why would a firm experience diminishing returns when adding units of labor?

Neoclassical economists postulate that each “unit” of labor is exactly the same, and diminishing returns are caused by a disruption of the entire production process as extra units of labor are added to a set amount of capital.

Why does a firm experience increasing returns to scale?

Increasing returns to scale occurs when a firm increases its inputs, and a more-than-proportionate increase in production results. When input prices remain constant, increasing returns to scale results in decreasing long-run average costs (economies of scale).

### What is meant by increasing returns to a variable factor discuss briefly any two reasons for the decreasing returns to a variable factor?

Answer : a) In short, run, assuming that the other factors of production or constant, the proportionate change in the total product is greater than the proportionate change in the units of a variable factor. This is called the law of increasing returns to a variable factor.

### What is the meaning of increasing returns to a factor?

In a short-run period when other factors of production remain constant if the proportionate change in TP is greater than the proportionate change in units of a variable factor, it is said to be the law of increasing returns to a variable factor.

What is returns to Factor?

Returns to a factor refers to the behaviour of physical output owing to change in physical input of a variable factor, fixed factors remaining constant.

#### What will happen to the cost of additional units of production when a firm start having diminishing returns?

The marginal cost of supplying an extra unit of output is linked with the marginal productivity of labour. The law of diminishing returns implies that marginal cost will rise as output increases. Eventually, rising marginal cost will lead to a rise in average total cost.

#### What happens to average product as additional units of labor are added to a fixed plant?

What happens to average product as additional units of labor are added to a fixed plant? As a firm expands the size of its plant, in the long-run, its total average costs rise. dividing total cost (TC) by that output (Q) or by adding AFC and AVC at that output.

At what level of output does the firm experience increasing returns to scale?

If the quantity of output rises by a greater proportion—e.g., if output increases by 2.5 times in response to a doubling of all inputs—the production process is said to exhibit increasing returns to scale.

## What are the causes of decreasing returns to a factor?

The law of diminishing returns applies because certain factors of production are kept fixed. If certain factor becomes fixed, the adjustment of factor of production will be disturbed and the production will not increase at increasing rates and thus law of diminishing returns will apply.

What is the main reason of law of increasing return?

Increasing returns to scale means that the increase in output is more than proportional to the increase in inputs. The main reason for this is the presence of cost advantages that arise due to expansion in the long run. These are called economies of scale and an there are of two types internal and external.

Put simply, increasing returns to scale occur when a firm’s output more than scales in comparison to its inputs. For example, a firm exhibits increasing returns to scale if its output more than doubles when all of its inputs are doubled. This relationship is shown by the first expression above.

This relationship is also called returns to a variable factor. The law states that keeping other factors constant, when you increase the variable factor, then the total product initially increases at an increases rate, then increases at a diminishing rate, and eventually starts declining.

What causes marginal returns to increase over time?

Increasing marginal returns occur when each additional unit of a variable factor input (e.g. labour) is adding more to total output than the previous additional unit. This occurs due to under-utilisation of the fixed factor inputs (e.g. capital).

#### Why does the law of increasing returns operate in the initial stage?

The law of increasing returns operate in the initial stage due to its idle capacity in the fixed factors of production while the law of diminishing returns operate in subsequent stage because that idle capacity is fully utilized. Therefore, both laws are said to be the two phases of a single tendency.

Put simply, increasing returns to scale occur when a firm’s output more than scales in comparison to its inputs. For example, a firm exhibits increasing returns to scale if its output more than doubles when all of its inputs are doubled. This relationship is shown by the first expression above.

#### How does a firm increase output in the long run?

In the short run, a firm can increase output only by increasing its use of a variable factor. But in the long run, all factors are variable, so the firm can expand the use of all of its factors of production.

The law of increasing returns operate in the initial stage due to its idle capacity in the fixed factors of production while the law of diminishing returns operate in subsequent stage because that idle capacity is fully utilized. Therefore, both laws are said to be the two phases of a single tendency.

How can you tell if a function is increasing returns to scale?

It tries to pinpoint increased production in relation to factors that contribute to production over a period of time. Most production functions include both labor and capital as factors. How can you tell if a function is increasing returns to scale, decreasing returns to scale, or having no effect on returns to scale?
