Answer to Question 1

Returns to scale summarize the response of a firm's output to equal percentage changes in all inputs. If all inputs are raised by equal percentages and output increases by a larger percentage, there are increasing returns to scale. Similarly, if all inputs are raised by equal percentages and output increases by a lesser percentage, there are decreasing returns to scale. If output changes by the same percentage as inputs, it implies constant returns to scale.
