Returns to Scale
After understanding diminishing returns in the short run, it's crucial to explore returns to scale, which apply in the long run when all inputs can be adjusted.
Returns to scale examine how output changes when all inputs are increased proportionally.
If output rises more than inputs, it's called Increasing Returns to Scale; if it increases in equal proportion, it's Constant Returns to Scale; and if it increases by less, it's Decreasing Returns to Scale. This concept is essential for long-term business expansion.
