MPN = w. In the example above, MPN = w = 50 when N = 3 workers. If the real wage increases to 75 lattes/day then labor demand falls to N = 2 and if w decreases to 25 lattes/day then N increases to 4. Clearly, there is an inverse relationship between Starbucks demand for labor and the real wage.Feb 24, 2019 · How is MPN calculated? The MPN Table (Table 4) is based on 3 dilutions of decreasing decimal increments.
