a. Increasing returns to scale.
- The increasing return's of scale refers to the Increase in the
productivity level in accordance to an increase in factor's of
production.
- An increasing return's to scale is said to occur when the
productivity or the output Increases more than the Increase in
inputs used.
- A firm becomes more efficient when it experiences increasing
return's to scale.
- For example: if a firms inputs used for production Increases by
5%, it is said to experience an increasing return's to scale if its
output Increases by 6% which is more than the increase in the
percent of inputs used.
b. Decreasing returns to scale.
- Decreasing returns to scale refers to the decrease in
productivity level in accordance to an increase in the factors of
production.
- Decreasing returns to scale is said to occur when the
productivity or output decreases when the number of inputs Increase
during the production process.
- When a firm faces decreasing returnsr to scale it becomes more
inefficient.
- For example : when the firms inputs Increase by 4 times and the
outputs decrease by 2 time, the firm is said to experience a
decreasing return's to scale.
