ACCT 503 – AT&T Case 1. Describe the cost behavior in the wireless industry. What are the implications of this cost behavior for cost-volume-profit (CVP) relationships? The term cost behavior is used to describe whether a cost changes as output changes. In this case the costs are tightly shielded. In order to describe the cost behavior of the industry‚ we have to study the process that results in cost incurrence. Based on the information in the AT&T case‚ the industry features a high proportion
