Treasury bills and treasury notes are an investment security issued by the u. s. government. a treasury bill matures within one year and investors typically roll over the matured treasury bill and purchase another treasury bill the same day. treasury notes have maturities of up to 10 years. you are considering investing $50,000 in a treasury bill that you will renew every 6 months or invest in a treasury note that you will hold until maturity. your investment time frame is 9 years. current investment opportunity interest rates are 5% and are expected to increase to 7% in 6 months. would you invest in the treasury bill that you can rollover every 6 months and reinvest or leave your money in the treasury note that will mature in 9 years? discuss your reasoning.

Consider two cigarette companies, pm inc. and brown inc. if neither company advertises, the two companies split the market and earn $50 million each. if they both advertise, they again split the market, but profits are lower by $10 million since each company must bear the cost of advertising. yet if one company advertises while the other does not, the one that advertises attracts customers from the other. in this case, the company that advertises earns $60 million while the company that does not advertise earns only $30 million. if these two companies collude and agree upon the best joint strategy, a. neither company will advertise. b. both companies will advertise. c. pm inc. will advertise but brown inc. will not. d. brown inc. will advertise but pm inc. will not.
