Capital and Financial Markets

1. Capital and Financial Markets

2. Capital and Financial Markets • Almost every weekday, each of the following is almost guaranteed to occur in United States • Managers at some corporation launch a new product • Covering costs with firm’s past profits, or raising funds from outside firm by issuing new shares of stock or new bonds • Owner of an apartment or office building sells it to a real estate developer, who plans to improve the property • An experienced registered nurse—earning about $44,000 a year—decides to apply for a costly two-year program to become a nurse practitioner, with starting salaries of around $56,000 • A new Starbucks opens its doors • A college professor goes online and buys a few hundred shares of stock in Amazon.com • A different college professor goes online and sells a few hundred shares of stock in Amazon.com

3. Capital and Financial Markets • In each case, a decision maker—consciously or unconsciously—is putting a value on money to be received in the future • This chapter focuses on decisions about • Investing in productive capital, such as factory buildings, equipment, or skills and training • Purchasing financial assets, such as stocks and bonds

4. Physical Capital and the Firm’s Investment Decision • How does a business firm decide how much physical capital to use? • Firm’s goal is to maximize its profit • Not just this year, but over many years into the future • Are there guidelines the firm should use? • Yes, but depends on conditions under which firm obtains and uses its capital

5. A First, Simple Approach • In this section, assume that one of two special conditions holds • Firms rent their capital at a constant price • Firms buy their capital, but it lasts forever • Marginal approach to profit states that a firm should take any action that adds more to its revenue per period than it adds to its cost per period • When firms rent capital, or the capital they buy lasts forever, we can apply marginal approach to profits just as we apply it for firm’s labor decision • Firm should buy another unit of capital whenever marginal revenue product > its marginal factor cost

6. Why the Simple Approach Usually Fails • The simple approach will not help us understand investment decisions, because assumptions are problematic • Our assumption that capital can be rented • Does not work for economy in general • Capital does not last forever • Length of time that capital lasts matters when deciding whether to buy it • Value of a future payment depends on when that payment is received

7. The Value of Future Dollars • Always preferable to receive a given sum of money earlier rather than later • Because present dollars can earn interest and • Because borrowing dollars requires payment of interest • Therefore, a dollar received later is worth less than a dollar received now • Present value (PV) of a future payment is the value of that future payment in today’s dollars • Alternatively, it is the most anyone would pay today for the right to receive the future payment • Present value of $Y to be received n years in the future is equal to

8. The Value of Future Dollars • Discounting • Converting a future value into its present-day equivalent • Discount rate • Interest rate used in computing present values • Present value of a future payment is smaller if • Size of the payment is smaller • Interest rate is larger • Payment is received later • Logic of present value shows why anyone who expects to receive a stream of future payments must discount each of those payments before adding them together

9. The Firm’s Demand for Capital • First step in making a decision about a capital purchase • Put a value on an additional unit of capital • Value is total present value of future revenue generated by the capital • Principle of asset valuation says that value of any asset is • Sum of present values of all future benefits it generates

10. What Happens When Things Change: The Investment Curve • Investment—firms’ purchases of new capital over some period of time • At high interest rates, U.S. firms end up buying less of all different kinds of capital • Thus, as interest rate rises, each firm will place a lower value on additional capital and decide to purchase less of it • In economy as a whole, a rise in interest rate causes a decrease in investment expenditures • Lower interest rates increase firms’ investment in physical capital • Causing capital stock to be larger, and overall standard of living to be higher

11. Figure 1: The Investment Curve

12. Investment in Human Capital • Economists are very interested in human capital investment • Who pays for workers to acquire human capital—the workers themselves, or the firms that employ them? • When an individual must pay to acquire human capital on his own, how does he make the decision?

13. General Versus Specific Human Capital • Economists classify human capital into • General human capital • Knowledge, education, or training that is valuable at many different firms • Specific human capital • Knowledge, education, or training that is valuable only at a specific firm • Reason for distinguishing between general and specific human capital • Firms have limited incentive to invest in general human capital because they cannot be sure of capturing all the benefits

14. General Versus Specific Human Capital • Employers have limited incentive to provide general human capital, • Since it increases worker’s value to many firms • Worker will capture benefits in the form of a higher wage • Therefore, workers must acquire general human capital on their own—or with help of government subsidies • Individuals have little incentive to pay for specific human capital • Since it increases their value to only one firm, and that firm will capture the benefits • Therefore, firms provide their workers with specific human capital at the firms’ expense

15. The Decision to Invest in General Human Capital • How do individuals make decision to acquire their own general human capital? • To the worker that possesses it, human capital is an asset that generates higher income in the future • Therefore, benefit of any given human capital investment is equal to total present value of additional future income • Investment in human capital is inversely related to interest rate • The lower the interest rate, the greater the benefits of any human capital investment, and the more human capital workers will want to acquire • Lower interest rates encourage individuals to invest in general human capital • Total amount of human capital—and overall standard of living—will be higher if interest rates are lower

16. Financial Markets • The pieces of paper being traded in financial markets are financial assets • Promises to pay future income to their owners • Because capital lasts for many years, most firms fund their capital purchases by issuing and selling financial assets • Close economic connection between a firm’s decision to be a demander in a capital market and • Its decision to be a supplier in financial markets • Because a financial asset gives holder a stream of future payments • Value of a financial asset is calculated in the same way as value of any other asset • Find total present value of future payments asset is expected to generate

17. The Bond Market • If a firm wants to buy a new fleet of trucks, build a new factory, or upgrade its computer system • Must decide how to finance the purchase • Perhaps by selling bonds • Bonds • Promise to pay a specific sum of money at some future date • Principal (face value) • Amount of money a bond promises to pay when it matures

18. The Bond Market • Maturity date • Date at which a bond’s principal amount will be paid to bond’s owner • Pure discount bond • Promises no payments except for principal it pays at maturity • Coupon payments • Series of periodic payments that a bond promises before maturity • Yield • Rate of return a bond earns for its owner

19. How Much is a Bond Worth? • Can determine present value of a bond with a face value of $10,000 which matures in exactly one year and has an interest rate of 10% • Bond will sell for $9,091 • Same principle applies to more complicated types of bonds • Such as discount bonds that don’t pay off for many years, or coupon bonds

20. How Much Is A Bond Worth? • Bond with a principal of $10,000, a five-year maturity and an annual coupon payment of $500 has a present value of • Total present value is what bond is worth • Price at which it will trade • As long as buyers and sellers use the same discount rate of 10% in their calculations

21. Bond Prices and Bond Yields • Inverse relationship between bond price and bond yields • The higher the price of any given bond the lower the yield on that bond

22. Primary and Secondary Bond Markets • Every type of financial asset is traded in two different types of markets • Primary market • Market in which newly issued financial assets are sold for first time • Secondary market • Market in which previously issued financial assets are sold • Applying this distinction to bonds • Primary bond market is where newly issued bonds are sold to their original buyers • Secondary bond market is where previously issued bonds change hands

23. Primary and Secondary Bond Markets • While bond issuers are not directly participants in secondary market trading, they are affected by what happens in secondary market • If a bond’s price rises in secondary market • Price one can charge for similar, newly issued bonds in the primary market will rise as well, or • If a bond’s yield falls in secondary market, yield of similar newly issued bonds in the primary market will fall as well

24. Why Do Bond Prices (and Bond Yields) Differ? • Thousands of different kinds of bonds are traded in financial markets every day • Each bond has its own unique yield • Why doesn’t each bond sell at a price that makes its yield identical to the yield on any other bond? • A bond—like any asset—is worth the total present value of its future payments

25. Why Do Bond Prices (and Bond Yields) Differ? • To put a value on riskier bonds, markets participants use a higher discount rate than on safe bonds • Leads to lower total present values and lower prices for riskier bonds • With lower prices, riskier bonds have higher yields • Riskiness is only one reason that bond prices and bond yields differ • Other reasons include • Differences in maturity dates • Differences in frequency of coupon payments • Because one bond is more widely traded (and therefore easier to sell on short notice) than another

26. The Stock Market • A share of stock, like a bond, is a financial asset that promises its owner future payments • But nature of promise is very different • When a corporation issues a bond, it is borrowing funds and promising to pay them back • But when a corporation issues a share of stock, it brings in new ownership of the firm itself • When a firm wishes to raise money in the stock market, it gets in touch with an investment bank

27. The Stock Market • The purpose of the prospectus is to inform potential investors of risks involved • Must be reviewed by Securities and Exchange Commission • Principal regulatory agency that oversees financial markets • If it is the first-ever offering of shares by this firm, sale will be called an initial public offering (IPO) • In practice, it’s usually large institutional investors, such as mutual funds, who first purchase new shares

28. Primary and Secondary Stock Markets • When a corporation issues new shares—as part of an IPO or a secondary offering—they are sold in a primary stock market • Only time a corporation receives any income from a trade in its stock is when the corporation itself sells the stock in the primary stock market • Thereafter, stock is traded in secondary market • Market in which previously issued shares are sold and resold • Secondary market is very important to firms that raise funds in primary market • Because of secondary market, people who buy shares know they can easily sell them when they want • Price changes in secondary market affect price a firm can get from selling shares in primary market

29. Direct and Indirect Ownership of Stock • Many people own shares of stock directly • Can also own stock indirectly • By purchasing shares of a mutual fund • Corporation that specializes in owning shares of stock in other corporations • A final way that households can—indirectly—own stock is through retirement accounts that are managed by their employers • These accounts should not be confused with 401(k) and 403(b) accounts that employees manage for themselves, in which the stock is owned directly or indirectly through mutual fund shares • Stock ownership in United States is growing rapidly • In 2002, about half of all American households owned shares of stock or mutual fund shares that they managed themselves • Up from about 19% of households in 1983

30. Why Do People Hold Stock? • Why do so many individuals and fund managers choose to put their money into stocks? • When you own a share of stock, you own part of the corporation • Most firms do not pay out all of profit to shareholders • Some of profit is kept as retained earnings, for later use by firm • Part of profit that is distributed to shareholders is called dividends • Another important reason people hold stocks • Hope to enjoy capital gains • Returns someone gets when they sell an asset at a higher price than they paid for it • Some stocks pay no dividends at all • Because management believes that stockholders are best served by reinvesting all profits so that future profits will be even higher • Over past century, corporate stocks have generally been a good investment

31. Valuing a Share of Stock • Value of a share of stock • Total present value of its future payments • But over what time horizon should stocks be valued? • Formulas to measure total present value of a firm’s future profits under a variety of different assumptions • For example, the simplest formula says • If a firm will earn a constant $Y in profit after taxes each year forever • Then total present value of these future profits is $Y ÷і, where і is the discount rate • Value of a share in a firm is equal to • Total present value of firm’s after tax profits divided by number of shares outstanding • Note that we are valuing a share of stock by future profits, not by dividends

32. Valuing a Share of Stock • Important conclusions about factors that can affect a stock’s value • An increase in current profits increases value of a share of stock • An increase in anticipated growth rate of profits increases value of a share of stock • A rise in interest rates—or even an anticipated rise in interest rates—decreases value of a share of stock • An increase in perceived riskiness of future profits decreases value of a share of stock

33. Reading the Stock Pages • In United States, financial markets are so important that stock and bond prices are monitored on a continuous basis • If you wish to know value of a stock, you can find out instantly by checking with a broker or logging on to a Web site that reports such information • To some people, the pages that cover the stock market look as impenetrable as Egyptian hieroglyphics • But information on the stock pages is very easy to understand, once you decide to learn it

34. Reading the Stock Pages • Figure 2 shows an excerpt from the New York Stock Exchange Composite Transactions reported in the July 9, 2003 Wall Street Journal • The data refer to the previous trading day—Wednesday, July 8, 2003 • Focus on stock of FedEx Corporation (listed as FedExCp) • First columns show percentage change in the stock’s price from a year ago, and highest and lowest prices paid during the past 52 weeks • Next columns show the stock’s name—abbreviated to FedExCp—followed by its stock symbol—FDX • Next two columns report firm’s most recent cash dividend—in this case .20, or 20¢ per share—and corresponding dividend yield, obtained by dividing most recent year’s dividends by current stock price

35. Figure 2: Stock Market Table for Trading on July 8, 2003

36. Reading the Stock Pages • Price-earnings (PE) ratio • Stock’s current price divided by its after-tax profit per share during previous 12 months • In general, an unusually high or unusually low PE ratio does not tell people whether the stock is relatively expensive or relatively cheap • One must also consider the stock’s future prospects • Remaining columns tell us about the most recent day’s transactions in this stock—July 8, 2003, in this case • Column headed Vol 100s indicates how many shares, in hundreds, traded on that day • Next column tells us last price at which FedExCp stock traded on that day • Final column—Net Chg—tells us that the price of a share of FedExCp stock decreased by $1.36 per share, from its price at the end of the pervious day’s trading

37. Reading the Stock Pages • In addition to reporting on individual stocks, Wall Street Journal and other newspapers also report on changes in different stock market averages or indexes • The most popular average is Dow Jones Industrial Average • Tracks prices of 30 of largest companies in United States, including Boeing, Microsoft, and Wal-Mart • Another popular average is the much broader Standard & Poor’s 500 • Tracks stock prices of 500 large corporations

38. Explaining Stock Prices • In examining Figure 2, you can see that most stocks experience a price change on any given day • Why? • Like all prices, stock prices are determined by supply and demand • On any given day, the number of FedExCp shares in existence is just the number that FedExCp has issued previously, up until that day • Therefore, no matter what happens to the price today, the number of shares remains unchanged • Just because 298 million shares of FedExCp stock actually exist • Does not mean that this is the number of shares that people want to hold • Value of a share of stock to any owner is equal to total present value of its future after-tax profits • At any given moment, there is an array of estimates of a stock’s total present value

39. Figure 3: The Market for FedEx

40. Figure 4: An Increase in Demand for Shares of FedEx

41. Explaining Stock Prices • Only at equilibrium price of $64 are people satisfied holding the number of shares they are actually holding • Where supply and demand curves intersect • Stocks achieve their equilibrium price almost instantly • Can have confidence that price of a share at any time is the equilibrium price • Cannot be caused by shifts in the supply curve • Must be caused by shifts in demand • What causes these sudden shifts in demand for a share of stock? • Logic of present value provides the answer • Anything that causes large groups of individuals to change their estimates of total present value of future profits will shift demand curve • When stock prices move dramatically, it is usually because new information has become available

42. The Economic Role of Financial Markets • What functions do financial markets play? • In the absence of capital markets, we would all be constrained to live as if there were literally no tomorrow • Would be poorer if there were no financial markets • Firms would have to grow solely via retained earnings • Would limit their growth rate • Would be constrained as individuals • Could not earn interest on savings • Economic functions that financial markets play • Facilitating large-scale production • Reallocating spending across time • Reducing risk • Disciplining management

43. Facilitating Large-Scale Production • Large industrial enterprises that are so common today are only about a century old • Prior to the 20th century, it would have been extremely unusual to find a business employing a hundred or more workers • As firms grew, so did their need to accumulate large sums of money • To take just a single example, think about railroads • New railroads turned to bond market for funding • Just as today’s large enterprises look to both stock and bond markets for cash to expand their operations • Without smoothly functioning financial markets, little of the remarkable economic growth of the past century could have occurred

44. Reallocating Spending Across Time • Financial markets allow firms to invest in new projects today rather than waiting until the necessary funds accumulate from current operations • Something similar is true for individual households • Financial markets allow them to reallocate their consumption over time • When you open a savings account, buy a bond, or invest in a mutual fund • You are reducing your consumption today in order to enjoy greater consumption in the future • Financial markets reallocate funds from • Surplus units • Mostly individuals who are not consuming their entire incomes today • To deficit units • Mostly firms that desire to spend more than their current income today • Markets help individuals, firms, and even government, to achieve best intertemporal utilization of resources

45. Reducing Risk • Prices of stocks and bonds serve several important functions that are not immediately obvious • Provide instantaneous feedback that allows corporate managers to see how they are doing • If stock price increases, and there has been no change in the discount rate • Means thousands of investors are—collectively—giving a vote of confidence in those policies • If price decreases • Means investors are voting with their dollars against the way firm is being managed • By checking prices of your competitors’ shares, you can form at least a rough estimate of what market is willing to pay for your shares • Once you begin to participate in the stock market • Existing share price will give you an indication of how much money you can raise by selling additional shares

46. Using the Theory: Can Anyone Predict Stock Prices? • Economists as a rule, don’t believe that anyone can do much better than you—an introductory economics student—reading this book and finding out about stock market for first time • No matter how smart • No matter how much research they do

47. Using the Theory—Predicting Stock Prices: Fundamental Analysis • One widely practiced method for predicting stock prices is fundamental analysis • Focuses on fundamental forces driving a firm’s future earnings • Value placed on those earnings by stock market participants • Fundamental analysts try to determine whether a stock is undervalued or overvalued relative to rest of the market

48. Using the Theory—Predicting Stock Prices: Technical Analysis • Idea is that, by graphing recent behavior of a stock’s price • Can predict whether stock is going to increase or decrease in value over the near future • Based on certain patterns • Technical analysts believe that stocks move in trends • Have numerous, colorful names for the patterns they claim to see • Each market participant has to determine what other participants are going to do • Daunting task that some people think can be handled by looking for patterns in stock prices

49. Using the Theory—The Economist’s View: Efficient Markets Theory • While economists believe that fundamental and technical analysis can often explain stock price movements in the past, they are extremely skeptical about anyone’s ability to predict stock price changes in the future • Implications of the efficient markets view are startling • You cannot, on average, beat the market by doing research and finding and buying under priced (or selling over priced) stocks • According to efficient markets view of stock market • Any information that can be used to predict a stock’s future earnings will be incorporated into stock’s price as soon as it becomes publicly available • By the time a fundamental analyst predicts that a stock’s price will rise or fall, it has already risen or fallen • Fundamental analysis cannot help you outperform market

50. Using the Theory—The Economist’s View: Efficient Markets Theory • According to efficient markets view of the stock market • Any pattern in stock price movements that can be observed by a good technical analyst will be incorporated into stock prices as soon as they are discernable • Therefore, stock market patterns disappear as soon as anyone can discover them • Technical analysis cannot help you outperform market
