ECON 326 HW Problem set 1 1. The menu at Joe’s coffee shop consists of a variety of coffee drinks, pastries, and sandwiches. The marginal product of an additional worker can be defined as the number of customers that can be served by that worker in a given time period. Joe has been employing one worker, but is considering hiring a second and a third. Explain why the marginal product of the second and third workers might be higher than the first. Why might you expect the marginal product of additional workers to eventually diminish? The marginal product could well increase for the second and third workers, since each of the first 2 or 3 workers would be able to specialize in a different task. If there is only 1 worker, then that worker will have to take orders and prepare all the food. Eventually, however, the marginal product would diminish because there would be too many people behind the counter trying to accomplish a limited number of tasks.
