1. Contrary to popular opinion, CEOs of major U.S. companies come from a wide variety of private universities and state universities, not just a handful of well-publicized MBA (DuBrin, 2016). What does this fact tell you about sources of power and organizational politics? DuBrin, A. (2016). Leadership: Research findings, practice, and skills (8th ed.). Boston, MA: Cengage. 2. Joint costs are sunk costs at the split-off point, the point in the disassembly process where all joint costs have been incurred. The company can make profit-maximizing decisions [which products to process further and which ones to sell at split-off] without making any joint cost allocations, so why make them? 3. Explain the death spiral. It sounds bad, but should it ever not be prevented? In other words, are there instances where the death spiral could be a good thing? I just need a paragraph minimum on each of the three questions. Please list reference in APA format.
