QUESTION 1 The Modigliani and Miller (MM) articles implicitly assumed that bankruptcy did not exist. That led to the development of the "trade-off" model, where the firm's value first rises with the use of debt due to the tax shelter of debt, but later falls as more debt is added because the potential costs of bankruptcy begin to more than offset the tax shelter benefits. Under the trade-off theory. an optimal capital structure exists. O True O False QUESTION 2 Modigliani and Miller (MM), in their second article, took account of taxes, bankruptcy, and other factors that were assumed away in their original article. Once they took account of all these assumptions, they concluded that every firm has a unique optimal capital structure. Moreover, a manager can use the second MM model to determine his or her firm's optimal debt ratio True O False
