Returns to scale refers to the rate by which output changes if all inputs are changed by the same factor. Under increasing returns to scale, the change in output is more than k-fold, under decreasing returns to scale; it is less than k- fold.

How do you describe returns to scale?

Returns to scale is a term that refers to the proportionality of changes in output after the amounts of all inputs in production have been changed by the same factor. Technology exhibits increasing, decreasing, or constant returns to scale.

There are three phases of returns in the long-run which may be separately described as (1) the law of increasing returns (2) the law of constant returns and (3) the law of decreasing returns.

What are the types of returns to scale?

There are three kinds of returns to scale: constant returns to scale (CRS), increasing returns to scale (IRS), and decreasing returns to scale (DRS). A constant returns to scale is when an increase in input results in a proportional increase in output.

What is the difference between law of Return and returns to scale?

The return to scale is different from the law of returns. Whereas return to scale describes the relationship between output and the variable inputs when all the inputs or factors are increased in the same proportion, the output may be more than double or less than double. The law of returns to scale has three stages.

What are the reasons for decreasing returns to scale?

Decreasing returns to scale occur if the production process becomes less efficient as production is expanded, as when a firm becomes too large to be managed effectively as a single unit.

What is the law of increasing returns to scale?

Increasing returns to scale or diminishing cost refers to a situation when all factors of production are increased, output increases at a higher rate. It means if all inputs are doubled, output will also increase at the faster rate than double.

What are laws of returns?

Generally, laws of returns to scale refer to an Page 2 increase in output due to increase in all factors in the same proportion. Such an increase is called returns to scale. Now, if both the factors of production i.e., labour and capital are increased in same proportion i.e., x, product function will be rewritten as.

What causes constant returns to scale?

When an increase in inputs (capital and labour) cause the same proportional increase in output. Constant returns to scale occur when increasing the number of inputs leads to an equivalent increase in the output.

What are the 3 stages of returns?

There are three possible types of returns to scale: increasing returns to scale, constant returns to scale, and diminishing (or decreasing) returns to scale. If output increases by the same proportional change as all inputs change then there are constant returns to scale (CRS).
