The second worker will probably be productive, as well. The sixteenth worker, however, would probably get nothing done, since there wouldn't be enough space or tools to make furniture. Between the second and the sixteenth worker, we would see a gradual drop in marginal productivity, a trend we call the Law of Diminishing Returns: additional workers may add to productivity, but each worker contributes less, until the marginal product (MP) is 0. Because firms will logically hire a new worker or pay for extra hours only as long as these actions will yield a net profit (MRP > w), we can assume that their demand curve is going to be the same as the curve representing the MRP of labor. This is because, as the MRP of labor falls, firms will hire less additional labor. When the MRP is high, they the MRP of labor falls, firms will hire less additional labor....
