Av city (problem 13.1) assumed with certainty that the order- ing cost is $625/order and the inventory carrying cost is $130/unit/ year. however, the inventory model parameters are frequently only estimates that are subject to some degree of uncertainty. consider four cases of variation in the model parameters as follows: (a) both ordering cost and carrying cost are 10% less than originally estim- ated; (b) both ordering cost and carrying cost are 10% higher than lus a few sundays, or approximately 320 days per year. determine the following: a. optimal order quantity per order b. total annual inventory costs c. optimal number of orders to place per year d. number of operating days between orders, based on the optimal orderin

Recently, verizon wireless ran a pricing trial in order to estimate the elasticity of demand for its services. the manager selected three states that were representative of its entire service area and increased prices by 5 percent to customers in those areas. one week later, the number of customers enrolled in verizon's cellular plans declined 4 percent in those states, while enrollments in states where prices were not increased remained flat. the manager used this information to estimate the own-price elasticity of demand and, based on her findings, immediately increased prices in all market areas by 5 percent in an attempt to boost the company's 2016 annual revenues. one year later, the manager was perplexed because verizon's 2016 annual revenues were 10 percent lower than those in 2015"the price increase apparently led to a reduction in the company's revenues. did the manager make an error? yes - the one-week measures show demand is inelastic, so a price increase will decrease revenues. yes - the one-week measures show demand is elastic, so a price increase will reduce revenues. yes - cell phone elasticity is likely much larger in the long-run than the short-run. no - the cell phone market must have changed between 2011 and 2012 for this price increase to lower revenues.
