Suppose two companies own adjacent oil fields, beneath which is a common pool of oil worth $30 million. For each well that is drilled, the company that drills the well incurs a cost of $3 million. Each company can drill one or two wells. Firms' revenues are proportional to their share of the total number of wells drilled; for example, if three wells have been drilled total of which one firm has two. it gets two- thirds of the oil revenues, or $20 million (gross). What is the likely outcome of this game if each company pursues its own self-interest? a. One company drills two wells and experiences a profit of $14 million; the other company drills one well and experiences a profit of $7 million.
b. Each company drills one well and experiences a profit of $15 million.
c. Each company drills two wells and experiences a profit of $9 million.
d. Each company drills one well and experiences a profit of $12 million.

Risk is the risk of a decline in a bond's value due to an increase in interest rates. this risk is higher on bonds that have long maturities than on bonds that will mature in the near future. risk is the risk that a decline in interest rates will lead to a decline in income from a bond portfolio. this risk is obviously high on callable bonds. it is also high on short-term bonds because the shorter the bond's maturity, the fewer the years before the relatively high old-coupon bonds will be replaced with new low-coupon issues. which type of risk is more relevant to an investor depends on the investor's , which is the period of time an investor plans to hold a particular investment. longer maturity bonds have high risk but low risk, while higher coupon bonds have a higher level of risk and a lower level of risk. to account for the effects related to both a bond's maturity and coupon, many analysts focus on a measure called , which is the weighted average of the time it takes to receive each of the bond's cash flows. conceptual question: which of the following bonds would have the largest duration? a)10year-zero coupon bonds b)10year-7% annual coupon bonds c)10year-3% annual coupon bonds d)5year-3% annual coupon bonds e)3year-7% annual coupon bonds
