Firms and production - Returns to scale
4 important questions on Firms and production - Returns to scale
What is the concept of "returns to scale" in economics?
- Measures changes in production as business scale changes.
- Focuses on how much output changes due to input changes.
- Related to whether outputs increase, decrease, or remain constant with proportional input increases.
What are increasing returns to scale (IRS) in economic theory?
- Occur when all inputs are increased by a factor, and output increases by more than that factor.
- Doubling inputs leads to more than double output.
- Exists if \( f(2L, 2K) > 2f(L, K) \).
- Enhanced by greater specialization and productivity in larger plants compared to smaller ones.
Explain Constant Returns to Scale (CRS) and its properties.
- If all inputs are increased by X%, output increases by X%.
- Doubling inputs results in doubling outputs.
- Production function: \( q = f(L, K) \).
- Property: \( f(2L, 2K) = 2f(L, K) \).

What defines decreasing returns to scale (DRS) in economic terms?
- Occur when all inputs are increased by a factor, and output increases by less than that factor.
- Doubling inputs results in less than double output.
- Exists if \( f(2L, 2K) < 2f(L, K) \).
- Caused by difficulties in organizing larger firms as size grows.
