  3. Learning Objectives • Assess the relative merits of two-period projects using net present value. • Define the term “competitive market,” give examples of markets that are competitive and some that aren’t, and discuss the importance of a competitive market in determining the value of a good. • Explain why maximizing NPV is always the correct decision rule. • Define arbitrage, and discuss its role in asset pricing. How does it relate to the Law of One Price? • Calculate the no-arbitrage price of an investment opportunity.

  4. Learning Objectives (cont'd) • Show how value additivity can be used to help managers maximize the value of the firm. • Describe the Separation Principle. • Calculate the value of a risky asset, using the Law of One Price. • Describe the relationship between a security’s risk premium and its correlation with returns of other securities. • Describe the effect of transactions costs on arbitrage and the Law of One Price.

  5. 3.1 Valuing Costs and Benefits • Identify Costs and Benefits • May need help from other areas in identifying the relevant costs and benefits • Marketing • Economics • Organizational Behavior • Strategy • Operations

  6. Using Market Prices to Determine Cash Values • Suppose a jewelry manufacturer has the opportunity to trade 10 ounces of platinum and receive 20 ounces of gold today. To compare the costs and benefits, we first need to convert them to a common unit.

  7. Using Market Prices to Determine Cash Values (cont'd) • Suppose gold can be bought and sold for a current market price of $250 per ounce. Then the 20 ounces of gold we receive has a cash value of: • (20 ounces of gold) ($250/ounce) = $5000 today

  8. Using Market Prices to Determine Cash Values (cont'd) • Similarly, if the current market price for platinum is $550 per ounce, then the 10 ounces of platinum we give up has a cash value of: • (10 ounces of platinum) ($550/ounce) = $5500

  9. Using Market Prices to Determine Cash Values (cont'd) • Therefore, the jeweler’s opportunity has a benefit of $5000 today and a cost of $5500 today. In this case, the net value of the project today is: • $5000 – $5500 = –$500 • Because it is negative, the costs exceed the benefits and the jeweler should reject the trade.

  14. When Competitive Market Prices Are Not Available • When competitive prices are not available, prices may be one sided. For example, at retail stores you can buy at the posted price, but you cannot sell the good to the store at that same price. One-sided prices determine the maximum value of the good (since it can always be purchased at that price), but an individual may value it for much less depending on his or her preferences for the good.

  15. Example 3.3

  16. Example 3.3 (cont'd)

  17. 3.2 Interest Rates and the Time Value of Money • Time Value of Money • Consider an investment opportunity with the following certain cash flows. • Cost: $100,000 today • Benefit: $105,000 in one year • The difference in value between money today and money in the future is due to the time value of money.

  18. The Interest Rate: An Exchange Rate Across Time • The rate at which we can exchange money today for money in the future is determined by the current interest rate. • Suppose the current annual interest rate is 7%. By investing or borrowing at this rate, we can exchange $1.07 in one year for each $1 today. • Risk–Free Interest Rate (Discount Rate), rf: The interest rate at which money can be borrowed or lent without risk. • Interest Rate Factor = 1 + rf • Discount Factor = 1 / (1 + rf)

  19. Example 3.4

  20. Example 3.4 (cont'd)

  21. Alternative Example 3.4 • Problem • The cost of replacing a fleet of company trucks with more energy efficient vehicles was $100 million in 2006. • The cost is estimated to rise by 8.5% in 2007. • If the interest rate was 4%, what was the cost of a delay in terms of dollars in 2007?

  22. Alternative Example 3.4 • Solution • If the project were delayed, it’s cost in 2007 would be: • $100 million × (1.085) = $108.5 million • Compare this amount to the cost of $100 million in 2006 using the interest rate of 4%: • $108.5 million ÷ 1.04 = $104.33 million in 2006 dollars. • The cost of a delay of one year would be: • $104.33 million – $100 million = $4.33 million in 2006 dollars.

  24. 3.3 Present Value and the NPV Decision Rule • The net present value (NPV) of a project or investment is the difference between the present value of its benefits and the present value of its costs. • Net Present Value

  25. The NPV Decision Rule • When making an investment decision, take the alternative with the highest NPV. Choosing this alternative is equivalent to receiving its NPV in cash today.

  26. The NPV Decision Rule (cont'd) • Accepting or Rejecting a Project • Accept those projects with positive NPV because accepting them is equivalent to receiving their NPV in cash today. • Reject those projects with negative NPV because accepting them would reduce the wealth of investors.

  27. Example 3.5

  28. Example 3.5 (cont'd)

  29. Choosing Among Projects

  30. Choosing Among Projects (cont'd) • All three projects have positive NPV, and we would accept all three if possible. • If we must choose only one project, Project B has the highest NPV and therefore is the best choice.

  31. NPV and Individual Preferences • Although Project B has the highest NPV, what if we do not want to spend the $20 for the cash outlay? Would Project A be a better choice? Should this affect our choice of projects? • NO! As long as we are able to borrow and lend at the risk-free interest rate, Project B is superior whatever our preferences regarding the timing of the cash flows.

  32. NPV and Individual Preferences (cont'd)

  33. NPV and Individual Preferences (cont'd) • Regardless of our preferences for cash today versus cash in the future, we should always maximize NPV first. We can then borrow or lend to shift cash flows through time and find our most preferred pattern of cash flows.

  35. 3.4 Arbitrage and the Law of One Price • Arbitrage • The practice of buying and selling equivalent goods in different markets to take advantage of a price difference. An arbitrage opportunity occurs when it is possible to make a profit without taking any risk or making any investment. • Normal Market • A competitive market in which there are no arbitrage opportunities.

  36. 3.4 Arbitrage and the Law of One Price (cont'd) • Law of One Price • If equivalent investment opportunities trade simultaneously in different competitive markets, then they must trade for the same price in both markets.

  37. 3.5 No-Arbitrage and Security Prices • Valuing a Security • Assume a security promises a risk-free payment of $1000 in one year. If the risk-free interest rate is 5%, what can we conclude about the price of this bond in a normal market? • Price(Bond) = $952.38

  38. 3.5 No-Arbitrage and Security Prices (cont'd) • Valuing a Security (cont’d) • What if the price of the bond is not $952.38? • Assume the price is $940. • The opportunity for arbitrage will force the price of the bond to rise until it is equal to $952.38.

  39. 3.5 No-Arbitrage and Security Prices (cont'd) • Valuing a Security (cont’d) • What if the price of the bond is not $952.38? • Assume the price is $960. • The opportunity for arbitrage will force the price of the bond to fall until it is equal to $952.38.

  40. Determining the No-Arbitrage Price • Unless the price of the security equals the present value of the security’s cash flows, an arbitrage opportunity will appear. • No Arbitrage Price of a Security

  41. Example 3.6

  42. Example 3.6 (cont'd)

  43. Determining the Interest Rate From Bond Prices • If we know the price of a risk-free bond, we can use to determine what the risk-free interest rate must be if there are no arbitrage opportunities.

  44. Determining the Interest Rate From Bond Prices (cont'd) • Suppose a risk-free bond that pays $1000 in one year is currently trading with a competitive market price of $929.80 today. The bond’s price must equal the present value of the $1000 cash flow it will pay.

  45. Determining the Interest Rate From Bond Prices (cont'd) • The risk-free interest rate must be 7.55%.

  46. The NPV of Trading Securities • In a normal market, the NPV of buying or selling a security is zero.

  47. The NPV of Trading Securities (cont’d) • Separation Principle • We can evaluate the NPV of an investment decision separately from the decision the firm makes regarding how to finance the investment or any other security transactions the firm is considering.

  48. Example 3.7

  49. Example 3.7 (cont'd)

  50. Valuing a Portfolio • The Law of One Price also has implications for packages of securities. • Consider two securities, A and B. Suppose a third security, C, has the same cash flows as A and B combined. In this case, security C is equivalent to a portfolio, or combination, of the securities A and B. • Value Additivity
