Answer to Question 2
The law of diminishing returns is the observation that as the quantity of one input increases with the quantities of all other inputs remaining the same, output increases but by ever smaller increments. Hence, as more workers (or capital) are used by a firm, each additional worker (or unit of capital) increases output, but by less than previous worker (or unit of capital). For instance, a law firm might have one paralegal typing briefs on one personal computer. Hiring an additional paralegal will increase the number of briefs, but with only one personal computer, the additional paralegal will not double the number of briefs. Similarly, buying another computer, while employing only one paralegal, might increase the number of briefs typed, but will not double the number.
