Notes: Carry 4 decimals for rates in your calculations to avoid excessive rounding Carry FIVE decimals for bond prices in the calculation of convexity!!! 1. You purchased a 20-year, 7.8 percent coupon bond that was priced at $980 NINE years ago. The bond paid monthly coupons. Right after you purchased the bond, interest rates fell by 240 bps and remained unchanged since then. You just liquidated your position by selling the bond at the end of vour 9-vear horizon. Calculate the annual) rate of return realized on your investment. 2a. b. Chapter 3 Slide 42 Exercise Problem Consider a 6% coupon 5-year bond with a $1,000 par value is priced to yield 8 percent. The bond pays coupon semi-annually with a duration of 4.36 years. Calculate the modified duration and convexity of the bond and use them to predict bond price after an increase of interest rates by 200 bps. Compare the predicted bond price to the new bond price (calculated with bond valuation). By how much does the convexity component improve bond price prediction? 3. a. MHM Bank currently has $300 million deposits on its balance sheet The Fed reduces the reserve requirement ratio from 11 percent to 9 percent. MHM Bank converts 80 percent of its excess reserves into loans and borrowers deposit 85 percent of their funds with MHM Bank. Calculate the change in money supply (monetary base), the new level of reserves,and the increase or decrease (select correct choice) in loans respectively, of MHM Bank. Numerically demonstrate the reduction in loan availability due to the drains in the financial system! Assume now that the Fed increases the reserve requirement ratio from 11 percent to 12 percent, and there is no drain in the financial system. Calculate the change in money supply (monetary base), the new level of reserves, and the increase or decrease (select correct choice) in loans, respectively, of MHM Bank. Assume now that the Fed purchases $100 million Treasury securities and keeps the reserve requirement ratio at 11 percent. MHM Bank converts 90 percent of its excess reserves into loans and borrowers hold 5% of their cash idle. Calculate the change in money supply ( monetary base), the new level of reserves, and the increase or decrease (select correct choice) in loans, respectively, of MHM Bank. b. c. 4a. A bank has issued a six-month, $5 million negotiable CD with a 0.65 percent quoted annual interest rate. Calculate (i) the bond equivalent yield on the CD; and (ii) the amount that the negotiable CD holder receive at maturity. (iii) Four months after the CD is issued, the secondary market price on the $5 million CD falls to $4,996,500. Calculate the new bond equivalent yield, and the secondary market guoted annual interest rate, on this CD.

A travel agency will plan a group tour for groups of size 30 or larger. If the group contains exactly 30 people, the cost is $380 per person. If each person's cost is reduced by $10 for each additional person above the 30, then the revenue is given by the equation shown below, where $x$ is the number of additional people above 30. $R(x) = (30 + x)(380 - 10x)$ Find the marginal revenue if the group contains 35 people. Interpret your result, The revenue will decrease by $1 if the group adds the absolute value of the marginal revenue number of people. The revenue will decrease by the absolute value of the marginal revenue in dollars if the group adds one person. The revenue will decrease by the absolute value of the marginal revenue in dollars if the group removes one person. The revenue will increase by the absolute value of the marginal revenue in dollars if the group adds one person. The revenue will increase by $1 if the group adds the absolute value of the marginal revenue number of people. Find $\frac{dy}{du}$, $\frac{du}{dx}$, and $\frac{dy}{dx}$ (a) $y = u^3$ and $u = x^2 + 2$
