To start, the firm has just enough business for one typist and one PC to keep busy for a day. Say that\u2019s five documents. Now suppose the firm receives a rush order from a good customer for 10 documents tomorrow. Ideally, the firm would like to use two typists and two PCs to produce twice their normal output of five documents. However, in the short turn, the firm has fixed capital, i.e. only one PC. The table below shows the situation:<\/p>\r\n\r\n<table id=\"eip-568\" summary=\"Table demonstrates the situation of the firm with the typists and the PC. With one typist, the workers product five letters per hour, and Marginal Productivity equals 5. With two typists, the firm produces seven letters per hour, and MP is 2. With three typists, they product 8 letters per hour, and MP is 1. For the remaining number of typists, 4, 5, and 6, the firm produces eight letters per hour, and MP is 0 for each.\"><caption>Short Run Production Function for Typing<\/caption>\r\n<tbody>\r\n<tr>\r\n<td># Typists (L)<\/td>\r\n<td>1<\/td>\r\n<td>2<\/td>\r\n<td>3<\/td>\r\n<td>4<\/td>\r\n<td>5<\/td>\r\n<td>6<\/td>\r\n<td><\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Letters\/hr (TP)<\/td>\r\n<td>5<\/td>\r\n<td>7<\/td>\r\n<td>8<\/td>\r\n<td>8<\/td>\r\n<td>8<\/td>\r\n<td>8<\/td>\r\n<td>For K = 1PC<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>MP<\/td>\r\n<td>5<\/td>\r\n<td>2<\/td>\r\n<td>1<\/td>\r\n<td>0<\/td>\r\n<td>0<\/td>\r\n<td>0<\/td>\r\n<td><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<p id=\"eip-72\">In the short run, the only variable factor is labor so the only way the firm can produce more output is by hiring additional workers. What could the second worker do? What can they contribute to the firm? Perhaps they can answer the phone, which is a major impediment to completing the typing assignment. What about a third worker? Perhaps he or she could bring coffee to the first two workers. You can see both total product and marginal product for the firm above. Now here\u2019s something to think about: At what point (e.g. after how many workers) does diminishing marginal productivity kick in, and more importantly, why?<\/p>\r\n<p id=\"eip-233\">In this example, marginal productivity starts to decline after the second worker. This is because capital is fixed. The production process for typing works best with one worker and one PC. If you add more than one typist, you get seriously diminishing marginal productivity.<\/p>\r\n<p id=\"eip-340\">Consider the long run. Suppose the firm\u2019s demand increases to 15 documents per day. What might the firm do to operate more efficiently? If demand has tripled, the firm could acquire two more PCs, which would give us a new short run production function as Table 7.4 below shows.<\/p>\r\n\r\n<table id=\"eip-741\" summary=\"The table illustrates the effects of two extra PCs on the firm. It adds to the previous table. With one PC, the firm can operate as follows: With one typist, the workers product five letters per hour, and Marginal Productivity equals 5. With two typists, the firm produces seven letters per hour, and MP is 2. With three typists, they product 8 letters per hour, and MP is 1. For the remaining number of typists, 4, 5, and 6, the firm produces eight letters per hour, and MP is 0 for each. With three PCs, one typist, the workers product five letters per hour, and Marginal Productivity equals 5. With two typists, the firm produces ten letters per hour, and MP is 5. With three typists, they product fifteen letters per hour, and MP is 5. With four typists, they produce 17 letters per hour, and MP is 2.
