Like cash flows, the interest rate can also be compounded over time. When compounding the interest rate we are simply accounting for the interest being earned on interest over a time period. One example of the computation of an annual compounded or effective interest rate is associated with your credit card. You recently received a letter from a local bank that offers you a new credit card that has no annual fee. It states that the annual percentage rate (APR) is 15 percent on outstanding balances. Note that the annual percentage rate does not account for compounding, rather the APR is simply the periodic rate times the number of periods. What is the effective annual interest rate? (This rate is subject to monthly compounding.)

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?
