Diana Baniak, searching for an Ecology class, knows that it must be in one of eight classrooms. Since the professor does not allow people to enter after the class has begun, and there is very little time left, she decides to try just four of the rooms at random. How many of the possible different selections of four rooms will succeed in locating the class?

Corporation b reported earnings per share of $10. corporation b has 100,000 shares of common stock outstanding and reported an increase in owners' equity of $400,000 for the period. corporation b paid $50,000 in interest expense during the period. corporation b paid dividends per share of

Consider a two-firm industry. firm 1 (the incumbent) chooses a level of output q1. firm 2 (the potential entrant) observes q1 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 q1 +q2. assume that the marginal cost of each firm is zero. a) find the subgame perfect equilibrium levels of q1 and q2 keeping in mind that firm 1 chooses q1 first and firm 2 observes q1 and chooses its q2. find the profits of the two firms-? 1 and ? 2- in the subgame perfect equilibrium. how do these numbers differ from the cournot equilibrium? b) for what level of q1 would firm 2 be deterred from entering? would a rational firm 1 have an incentive to choose this level of q1? 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 q1, denoted by q1b, as a function of f. next, derive the expression for firm 1
