Which of the following statements is CORRECT? a. The bond-yield-plus-risk-premium approach is the most sophisticated and objective method for estimating a firm's cost of equity capital. b. The cost of capital used to evaluate a project should be the cost of the specific type of financing used to fund that project, i. e., it is the after-tax cost of debt if debt is to be used to finance the project or the cost of equity if the project will be financed with equity. c. The after-tax cost of debt that is used as the component cost when calculating the WACC is the average after-tax cost of the firm's outstanding debt. d. The cost of equity is generally harder to measure than the cost of debt because there is no stated, contractual cost number on which to base the cost of equity. e. Suppose some of a publicly-traded firm's stockholders are not diversified; they hold only the one firm's stock. In this case, the CAPM approach will result in an estimated cost of equity that is too low in the sense that if it is used in capital budgeting, projects will be accepted that will not maximize the firm's intrinsic values.

1. consider a two-firm industry. firm 1 (the incumbent) chooses a level of output qı. firm 2 (the potential entrant) observes qı and then chooses its level of output q2. the demand for the product is p 100 q, where q is the total output sold by the two firms which equals qi +q2. assume that the marginal cost of each firm is zero. a) find the subgame perfect equilibrium levels of qi and q2 keeping in mind that firm 1 chooses qi first and firm 2 observes qi and chooses its q2. find the profits of the two firms-n1 and t2- in the subgame perfect equilibrium. how do these numbers differ from the cournot equilibrium? b) for what level of qi would firm 2 be deterred from entering? would a rational firm 1 have an incentive to choose this level of qi? which entry condition does this market have: blockaded, deterred, or accommodated? now suppose that firm 2 has to incur a fixed cost of entry, f> 0. c) for what values of f will entry be blockaded? d) find out the entry deterring level of q, denoted by q1', a expression for firm l's profit, when entry is deterred, as a function of f. for what values of f would firm 1 use an entry deterring strategy?
