Models. Behaving. Badly.: Why Confusing Illusion With Reality Can Lead to Disaster, on Wall Street and in Life by Emanuel Derman

One of the lessons of the credit crisis that began in 2007 is that the models used to determine the value of mortgage securities did not include in their expectations the possibility of the catastrophic future scenarios that actually occurred. The Law of One Price: Similar Securities Have Similar Prices To answer a general question requires having a principle. The only principle you can rely on in finance (and it’s not always reliable) is the Law of One Price: If you want to know the value of one financial security, your best bet is to use the known price of another security that’s as similar to it as possible. When we compare it with almost everything else in economics, the wonderful thing about this law of valuation by analogy is that it dispenses with utility functions, the undiscoverable hidden variables whose ghostly presence permeates economic theory. Financial economists like to recast the Law of One Price as the more pedantically named Principle of No Riskless Arbitrage: Any two securities with identical future payoffs, no matter how the future turns out, should have identical current prices.

Financial economists like to recast the Law of One Price as the more pedantically named Principle of No Riskless Arbitrage: Any two securities with identical future payoffs, no matter how the future turns out, should have identical current prices. This Law of One Price embodies the common sense that the author of “the fundamental theorem of finance” was trying so hard to convey but expressed so unclearly. In the imaginary world of the Efficient Market Model, a stock’s price movements are completely characterized by its expected return μ and its volatility a. All that differentiates one stock from another is their respective values of μ and σ—nothing else. Two securities with the same μ and σ are therefore similar. The Law of One Price combined with the EMM then leads to the following conclusion: Any two securities with the same foreseeable volatility should have the same expected return.9 There is a shallow resemblance between the Law of One Price in finance and Einstein’s principle of relativity in physics, presented in the table below.

Principle of Relativity Law of One Price All observers, irrespective of their speeds, should, from their observations, deduce the same equations for the laws of nature. All securities with identical risk, irrespective of their nature, should provide the same expected return. Light is special; nothing can move faster than light. Riskless bonds are special; nothing can have less risk than a riskless bond. The Law of One Price is not, however, like the principle of relativity. It is not a consistent law of nature. It is a general reflection on the practices of fickle human beings, who, when they have enough time, resources, and information, would rather buy the cheaper of two similar securities and sell the richer, thereby bringing their prices into equilibrium.

One possible approach to testing whether prices are “right” is to employ an important principle at the very heart of the EMH: the law of one price. The law asserts that in an efficient market, the same asset cannot simultaneously sell for two different prices. If that happened, there would be an immediate arbitrage opportunity, meaning a way to make a series of trades that are guaranteed to generate a profit at no risk. Imagine that gold sells for $1,000 an ounce in New York and $1,010 an ounce in London. Someone could buy gold contracts in New York and sell them in London, and if the transaction costs of making that trade are small, money can be made until the two prices converge. The existence of a multitude of smart traders who are constantly on the lookout for violations of the law of one price guarantees that it should hold, almost precisely and instantaneously.

” † To be clear, it can be quite smart to invest in closed-end funds when they sell at a discount, but it is foolish to buy one when it is first issued and a commission is being charged. 26 Fruit Flies, Icebergs, and Negative Stock Prices The debate with Merton Miller obscured the most important point about closed-end funds: the blatant violation of the law of one price. It was as if we had discovered a unicorn and then had a long fight about what to call the color of the beast’s coat. Years later, after I had joined the University of Chicago, I revisited the law of one price with a Chicago colleague, Owen Lamont. At that time Owen was not really a behavioral economist. He was just an open-minded researcher who enjoyed stirring the pot and had a good eye for interesting problems. Owen is always a favored choice for the role of discussant at the behavioral finance seminars that Shiller and I organize at NBER.

FIGURE 16 There is a first principle of finance even more fundamental than the law of one price, which is that a stock price can never be negative. You can throw your shares away if you want to, and shareholders have limited liability, so the absolute lowest a stock price can fall to is zero. No company can be worth minus $100, much less minus $23 billion. But that is what the market was saying. Think of it another way. Suppose an Econ is interested in investing in Palm. He could pay $95 and get one share of Palm, or he could pay $82 and get one share of 3Com that includes 1.5 shares of Palm plus an interest in 3Com. That does not seem to be a tough decision! Why buy Palm directly when you can get more shares for less money by buying 3Com, plus get a stake in another company thrown in for free? This was a colossal violation of the law of one price. In fact it was so colossal that it was widely publicized in the popular press.

Trading costs, lack of liquidity, the bid-ask spread, constant moves of the market that tend to quickly eliminate any arbitrage opportunity, and the impossibility of executing large enough trades without moving the markets make it very difficult to capitalize on arbitrage opportunities. In an arbitrage-free market, we can infer relationships between the prices of various securities, based on the following principle: Theorem 1.10. (The (Generalized) Law of One Price.) If two portfolios are guaranteed to have the same value at a future time T > t regardless of the state of the market at time T, then they must have the same value at time t. If one portfolio is guaranteed to be more valuable (or less valuable) than another portfolio at a future time T > t regardless of the state of the market at time T, then that portfolio is more valuable (or less valuable, respectively) than the other one at time t < T as well: If there exists T > t such that Vi(T) = V2(T) (or Vi(T) > V2(T), or Vi(T) < ~(T), respectively) for any state of the market at time T, then Vi(t) = ~(t) (or Vi(t) > V2(t), or Vi(t) < ~(t), respectively).

If one portfolio is guaranteed to be more valuable (or less valuable) than another portfolio at a future time T > t regardless of the state of the market at time T, then that portfolio is more valuable (or less valuable, respectively) than the other one at time t < T as well: If there exists T > t such that Vi(T) = V2(T) (or Vi(T) > V2(T), or Vi(T) < ~(T), respectively) for any state of the market at time T, then Vi(t) = ~(t) (or Vi(t) > V2(t), or Vi(t) < ~(t), respectively). Corollary 1.1. If the value of a portfolio of securities is guaranteed to be equal to 0 at a future time T > t regardless of the state of the market at time T, then the value of the portfolio at time t must have been 0 as well: If there exists T > t such that V(T) = 0 for any state of the market at time T, then V(t) = o. An important consequence of the law of one price is the fact that, if the value of a portfolio at time T in the future is independent of the state of the market at that time, then the value of the portfolio in the present is the risk-neutral discounted present value of the portfolio at time T. Before we state this result formally, we must clarify the meaning of "riskneutral discounted present value". This refers to the time value of money: cash can be deposited at time tl to be returned at time t2 (t2 > tl), with interest.

The value l;2(T) of this portfolio at time T is l;2(T) = er(T-t) l;2(t) = er(T-t) (ze-r(T-t)) z', cf. (1.42) for tl = t, t2 = T, and B(t) = l;2(t). Thus, l;2(T) = V(T) = z, and, from Theorem 1.10, we conclude that l;2(t) = V(t). Therefore, V(t) = l;2(t) = ze-r(T-t) = V(T) e-r(T-t) , which is what we wanted to prove. D P(t) + S(t)e-q(T-t) - C(t) = Ke-r(T-t). (1.47) We prove (1.46) here using the law of one price. Consider a portfolio made of the following assets: • long 1 put option; • long 1 share; • short 1 call option. The value5 of the portfolio at time t is VportJolio(t) = P(t) + S(t) - C(t). (1.48) - C(T) = K, (1.49) It is easy to see that Example: How much are plain vanilla European options worth if the value of the underlying asset is 07 Answer: If, at time t, the underlying asset becomes worthless, i.e., if S(t) = 0, then the price of the asset will never be above 0 again.

Derivatives Markets by David Goldenberg

To summarize, the payoff to the difference between a long spot position and a long forward position is exactly the same as the payoff to a long position in a zero-coupon bond with face value equal to the forward price, and maturing at the same time as the forward contract. In the language of financial engineering, we have replicated the payoff to the original (natural) difference strategy by a synthetic strategy which is simply to buy the appropriate zero-coupon bond. Buy because we need to generate a positive cash flow equal to +Ft,T at time T. A basic principle of finance (the no-arbitrage principle, or the law of one price) is that if you can do what we just did, then the current costs of the two strategies must be the same. Otherwise, there would be a quick arbitrage opportunity. We will get into all this soon, but let’s just follow through with what we have derived and see its pricing implications. 78 FORWARD CONTRACTS AND FUTURES CONTRACTS So, consider the current cost(s) of generating these alternative payoffs.

In this case, the current cost to us of doing so is e–(r–)*F′t,T since we are lending, not borrowing. We are implicitly assuming that the borrowing rate is equal to the lending rate. To avoid arbitrage these two strategies, strategy 1.–2., and lending the PV of F′t,T must have the same current cost, St=e–(r–)*F′t,T . To see this, you can construct the arbitrage opportunity directly, or use the law of one price (LOP), which follows from no-arbitrage. It follows that F′t,T =e(r–)*St . The ′ indicates that we are solving for the forward price in the presence of dividends. Note that this is the same pricing by replication argument that we gave in Chapter 3, section 3.5, for the no-dividend case. Also note that replication implies pricing because the replicating portfolio must have the same price as the strategy it replicates.

So, we do not need an independent application of the principle of no-arbitrage to show that the current cost of the replicating portfolio must be equal to the price of the derivative security. Market completeness guarantees that, because it implies no-arbitrage, in our interpretation. The usual argument given for equality between the cost of the replicating portfolio and the derivative it is replicating is that no-arbitrage implies the Law of One Price (LOP), which says that the two economically equivalent financial instruments cannot trade for different prices. This is pretty clear. If LOP did not hold, then there would be an arbitrage opportunity. The LOP construct is cute, and weaker than no-arbitrage, but not needed. Furthermore, there is no particular benefit to considering a market in which just the weaker LOP holds. The relevant market is one in which there are linear, positive pricing mechanisms, that is, markets in which there are no arbitrage opportunities.

Similarly, a three-year Treasury bond is a collection of six zero-coupon bonds respectively maturing every successive six months over the next three years. Decomposed in this way, the bonds' ingredients are shared: Both contain the first six zero-coupon bonds. Therefore, in modeling the three-year bond, you are also implicitly modeling parts of the five-year bond. In essence, Ravi's model allowed impermissible violations of the law of one price that lies beneath all rational financial modeling. This law demands that any two securities with the same final payouts must have the same current value. Now, there is a combination of short-term options on long-term bonds that has exactly the same payout as a short-term bond, and therefore, the combination of options should have the same theoretical value as the short-term bond, despite their formally different names.

We had aimed to make our model simple and consistent, and it waswe could match all current bond prices with one tree. We could then use the same calibrated tree to value any security whose payouts in the future had a known dependence on interest rates by averaging those payouts over the distribution. In particular, we could value the payout of an option of any expiration on a bond of any maturity. It was particularly attractive that our new model satisfied the law of one price. Our tree functioned as a computational engine that produced the current value of a security by averaging its future payouts; you put future payouts onto the end of the tree, cranked the handle that averaged and then discounted them over the interest rate distribution, and ended up with the current price. The engine didn't care what name you gave to the security that produced the payout-bond, option, call it what you like.

Our traders' intuition had been honed on the old model, and they were sensibly conservative about switching-it is never wise to start using something new until you understand how well it glues on to what you used before. You need a feel for a model before you can begin to rely on it. Therefore, some of the sales assistants in Financial Strategies began to test it, and slowly convinced themselves that it satisfied the law of one price, something that was theoretically obvious to us but not yet practically clear to them. I was tremendously excited by what we had done. Still at heart a physicist, and still philosophically naive about financial modeling, I halfthought of what we had built as a grand unified theory of interest rates, and imagined we could use it to value every interest rate-sensitive security in the universe.

Efficiently Inefficient: How Smart Money Invests and Market Prices Are Determined by Lasse Heje Pedersen

While the Two-Fund Separation Theorem stipulates that all investors should hold the market portfolio in combination with cash or leverage, most real-world investors hold different portfolios, where some avoid leverage and instead concentrate in risky securities, whereas others (such as Warren Buffett) leverage safer securities. Asset returns are not just influenced by their market risk (as in the CAPM); they are also influenced by market and funding liquidity risk since investors want to be compensated for holding securities that are difficult to finance or entail the risk of high transaction costs. The Law of One Price breaks down when arbitrage opportunities arise in currency markets (defying the covered interest rate parity), credit markets (the CDS-bond basis), convertible bond markets, equity markets (Siamese twin stock spreads), and option markets. Investors exercise call options and convert convertible bonds before maturity and dividend payments when they need to free up cash or face large short sale costs (defying Merton’s Rule).

To prove that the outcome they describe is the only possible outcome, Modigliani and Miller make what is probably their most ingenious contribution to the theory of finance. They seize on a common feature of competitive markets and elevate it to the level of a driving force. In so doing they make a significant advance over both Williams and Durand. That feature is known as arbitrage, or, among economic theorists, as the Law of One Price. Two assets with identical attributes should sell for the same price, and so should an identical asset trading in two different markets. If the prices of such an asset differ, a profitable opportunity will arise to sell the asset where it is overpriced and to buy it back where it is underpriced. The arbitrager will then lock in a sure profit, otherwise known as a free lunch. The familiar aphorism that “There is no such thing as a free lunch” applies only to perfect markets, imperfect markets provide a playground for the “arbs,” as they are known in Wall Street slang.

Recalling their discussions about this line of argument, Miller smiled and said, “Franco has the mind of an arbitrager, an Italian currency speculator. He always thinks in those terms.”11 Modigliani, in an understatement, observed that this approach was what made their 1958 paper “quite novel, even beyond the radical character of the core topic.”12 Even tourists ignorant of the theory of finance can turn into arbitragers. The Law of One Price was violated in the early 1980s when the foreign exchange rate for the dollar was so high that everything abroad seemed extraordinarily cheap to Americans. A Wall Street Journal reporter demonstrated that an American who flew to London, enjoyed fancy meals and hotel accommodations for a few days, and loaded up on items like sweaters, whiskey, and china, could save enough money, compared to the cost of the same items in New York City, to cover the cost of the round-trip airfare.

General Electric took a different path and used what is known as leverage: It issued only $60 million in common stock and borrowed $40 million by issuing bonds paying 5 percent a year interest. With only common stock outstanding, General Motor’s total earnings of $ 10 million accrue to the owners of its shares. General Electric, however, must first pay interest of $2 million on its bonds, leaving $8 million for its stockholders. What happens if the Law of One Price is violated? Suppose General Motors stock is selling for its issue value of $100 million, while General Electric stock is selling for $70 million, or $10 million more than its issue value of $60 million. Together with its $40 million in bonds, General Electric as a totality is valued in the market place at $110 million, more than the market value of General Motors. Despite the different market valuations, the two companies still have identical earning power and riskiness.

The bids will fall until the woman who faces leaving alone is offering to walk through the checkout with some lucky guy and accept just one cent as the price of doing so. He’ll get $99.99; her one-cent profit is better than nothing. The trouble doesn’t end there. Economists talk about “the law of one price,” which says that identical products on offer at the same time, in the same place, with the prices clearly visible will go for the same price. This is the Marriage Supermarket, so that’s exactly the situation the women find themselves in. No matter what deals are agreed, there will always be one girl left over, offering to pair up for just one cent. The law of one price says one cent is what all of them will get: Anyone on the verge of getting a better offer will be undercut. The nineteen men will each get $99.99. Nineteen women will get a cent each, and the last woman will get nothing at all.

That’s remarkable: A shortage of just one man gives all the other men massive scarcity power. The intuition is straightforward, though. Just one “leftover” woman can provide an outside option for every single man and spoil the bargaining position of every other woman. That’s how it would work in the Marriage Supermarket. You may have noticed some minor differences in reality. The conditions for the law of one price are never perfectly met. The bargaining process is not quite as calculating, although it is probably just as brutal. Most important, because the Marriage Supermarket measures the benefits of marriage in dollars, those benefits are easily transferred from one party to another. In reality, it’s not as easy for suitors to bid against one another as marriage prospects (“I’ll match Brian’s guarantee of three orgasms per week, and add in at least one candlelit dinner”)—although the marriage of twenty-six-year-old former Playboy centerfold Anna Nicole Smith to eighty-nine-year-old billionaire J.

Loren Brandt and Thomas Sargent (1989) regard this additional evidence as suggesting that the episode was one of "free banking" on a specie standard in which the higher real price of silver meant that a smaller physical stock of silver was necessary to support the same total stock of money in nominal units. The price deflation, they suggest, was produced by the "law of one price," that is, arbitrage between international and domestic prices, rather than by monetary contraction. And prices, they conjecture, were sufficiently flexible to insulate the real economy from the price deflation produced by the "law of one price." The higher value of silver was simply a boon to holders of silver, and to benefit from that boon they exported the amount no longer needed to support the money stock. They conclude that "the U.S. silver purchase program did not set off a chain of bad economic events which eventually forced China off silver and onto a fiat standard.

It is exactly because much of what goes on in an economy is about distributing economic rents, rather than maximizing allocative efficiency, that the European social model has been much more successful than it would have been if perfect competition had any semblance to reality. At the bottom of the power hierarchy are the workers (Chapter 5). Workers do not exist in most neoclassical models of the labor market. There is only labor in those markets – labor that consumers sell if the price is right and do not sell if the price is too low. In reality, the firm employs workers, not their labor. The presence of market power, established in Chapter 4, implies that the law of one price for labor does not hold. The result is a dichotomy of good jobs and bad jobs for similar workers. Thus luck is very important for earnings and careers, rather than individual merit. Labor market institutions, and legal restrictions on voluntary trade, work very differently on such a real labor market than in the fairy-tale labor market that textbooks like to use. The final chapter deals with the thorny question of who can deal with economic power if the spheres of economic power and political power are connected.

Just as workers will demand a higher wage for travelling to an otherwise identical employer who is further away, they will demand more money if they are expected to do work which they do not like as much (Bhaskar, Manning and To 2002). Empirical research has provided ample direct and indirect proof of the importance of market power on the labor market. An indirect proof lies in the fact that the law of one price routinely does not hold. If competition worked as neoclassical theory assumes, there would be one price for labor of a given type and quality. However, there is a large body of literature dating back many decades that shows that wage rates can be very different for a given type of work in a given city. One such study from 2002 cites, as informal but impressive evidence, a survey of six fast food restaurants located within a one mile radius.

The correlation’s source, according to the article, is industries seem to be moving in harmony around the world.2 My interpretation of the author’s conclusion is people who aim at diversifying their portfolios must pay as much attention to industry groups as they do to global locations. I have been making this point for the past few years; such a correlation trend is entirely predictable. The high correlation among industry returns across countries is easily explained in terms of the “law of one price,” or purchasing power parity (PPP). Putting these similar concepts together, the high correlation is explainable because identical things’ prices across countries tend to be equal when expressed in the same currency. To the extent the correlation among industries is not perfect, however, one must conclude PPP is not perfect and PPP violations occur. In fact, these violations are what give rise to location effects, which include entire global regions, specific countries, and smaller localities.

By the time this book was written, the lead-lag effect between futures and spot markets had decreased from the 5- to 10-minute period documented by Stoll and Whaley (1990) to a 1- to 2-second advantage. However, profit-taking opportunities still exist for powerful high-frequency trading systems with low transaction costs. Indexes and ETFs Index arbitrage is driven by the relative mispricings of indexes and their underlying components. Under the Law of One Price, index price should be equal to the price of a portfolio of individual securities composing the index, weighted according to their weights within the index. Occasionally, relative prices of the index and the underlying securities deviate from the Law of One Price and present the following arbitrage opportunities. If the price of the index-mimicking portfolio net of transaction costs exceeds the price of the index itself, also net of transaction costs, sell the index-mimicking portfolio, buy index, hold until the market corrects its index pricing, then realize gain.

On the other hand, the weak form of the convexity axiom would permit a multi-valued demand correspondence. 4.4.2 The No Arbitrage Principle Definition 4.4.1 An arbitrage opportunity means the opportunity to acquire a consumption vector or its constituents, directly or indirectly, at one price, and to sell the same consumption vector or its constituents, directly or indirectly, at a higher price. Theorem 4.4.1 (The No Arbitrage Principle) Arbitrage opportunities do not exist in equilibrium in an economy in which at least one agent has preferences which exhibit local non-satiation.2 2 The No Arbitrage Principle is also known as the No Free Lunch Principle, or the Law of One Price Revised: December 2, 1998 CHAPTER 4. CHOICE UNDER CERTAINTY 71 Proof If preferences exhibit local non-satiation, then Marshallian demand is not well-defined if the price vector permits arbitrage opportunities. If the no arbitrage principle doesn’t hold, then any individual can increase wealth without bound by exploiting the available arbitrage opportunity on an infinite scale. Thus there is no longer a budget constraint and, since local non-satiation rules out bliss points, utility too can be increased without bound.

Recklessness could lead to the sad fate of Giordano Bruno (1548–1600), arrogance to that of Galileo. But overall, the system worked well as a competitive market for ideas. After 1650, the power of conservative forces to hold back new ideas dissolved north of the Alps and the Pyrenees. That said, unlike highly competitive markets for goods or labor, the market for ideas does not invariably converge to an “equilibrium outcome,” comparable to the law of one price in markets for goods. The reason is that even if the market for ideas is highly competitive, it may be difficult for “consumers” to choose on the basis of content alone, because knowledge is insufficiently tight and the evidence or data are inconclusive. In that case the market generates multiple solutions. In some sense multiple equilibria in the market for ideas can be viewed as an inefficiency, since if there are two diametrically inconsistent ideas extant about some natural phenomenon, at least one of them is likely to be in error.

Such was the case in medicine, where best-practice knowledge before 1870 could not produce a tight explanation of infectious disease. But in a well-functioning market for ideas, content bias—the willingness to be persuaded and accept what seems true—should be decisive in matters that can be verified by the best instruments and satisfy the rhetorical conventions of the time.21 In that case something akin to the law of one price should obtain. Hence, when such cultural entrepreneurs as Lavoisier, Darwin, and Pasteur proposed radically new views of natural phenomena, the evidence and logic were judged to be persuasive by the rhetorical standards of their age. Notwithstanding skepticism and resistance, their ideas became eventually accepted and were considered to be sufficiently tight at least among those who mattered for further progress.

Why Stock Markets Crash: Critical Events in Complex Financial Systems by Didier Sornette

Thaler concluded that rather than rationally pricing mortality, people had a cognitive disconnect; they put a premium on new risks and casually discounted familiar ones [272]. In experiments designed to test his ideas, Thaler found that subjects would usually agree to pay more for a drink if they were told that the beer is being purchased from an exclusive hotel rather than from a rundown grocery. It strikes them as unfair to pay the same. This violates the law-of-one-price that one drink is worth the same as another, and it suggests that people care as much about being treated fairly as they do about the actual value of what they are paying for [227, 228]. An important discovery, extending the framing principle of Kahneman and Tversky, was “mental accounting” [423, 373]. “Framing” says that the positioning of choices prejudices the outcome, an issue that received a lot of publicity in the 2000 U.S. presidential election.

Another example is that the fundamental equations of motion of so-called “strings,” formulated to describe the fundamental particles such as quarks and electrons, derive from global symmetry principles and dualities between descriptions at long-range and short-range scales. Are there similar principles that can guide the determination of the equations of motion of the more down-to-earth financial markets? The Principle of Absence of Arbitrage Opportunity One such organizing principle is the condition of absence of arbitrage opportunity, which we have already visited in chapter 2. Recall that no-arbitrage, also known as the Law of One Price, states that two assets with identical attributes should sell for the same price, and so should the same asset trading in two different markets. If the prices differ, a profitable opportunity arises to sell the asset where it is overpriced model ing bubbles a n d c r a s h e s 137 and to buy it where it is underpriced. The basic idea is that, if there are arbitrage opportunities, they cannot live long or must be quite subtle, otherwise traders would act on them and arbitrage them away.

Producers aren’t necessarily thrilled with consumer surplus. They’d rather get all the money each customer is willing to pay (and sometimes they find a way to do that by charging them different prices). But more often they can’t. In competitive markets with well-informed consumers, the same products sell for the same single price everywhere. It’s a phenomenon so consistent that it’s known in economics as the “law of one price.” The triangle to the right of the revenue rectangle represents consumers who didn’t get the product because they weren’t willing or able to pay P* for it. They are the segment of the market that is unserved at what’s called the “market equilibrium price.” Figure 5 The supply and demand graph that appears in every microeconomics textbook An iPhone has a demand curve that looks something like the one in Figure 3, and so does each available app for the phone.

• Even with stocks, there are occasions where an issuer has enough monopoly power to create (deliberate or accidental) scarcity. A well-known example is the Palm/3Com case, in which, near the peak of the dot.com mania, 3Com spun off its subsidiary Palm, selling 5% of its shares in the open market and promising the rest later. Palm instantly acquired a greater total market capitalization than its corporate parent 3Com, implying that the stub (3Com ex Palm) had a negative value. The Law of One Price clearly did not apply. Too few shares of Palm were available for arbitrageurs to take advantage of the opportunity (to sell Palm shares and buy 3Com shares, earning a large riskless profit). Once further Palm shares became available, this anomaly disappeared.

This means that in any single market, competition will tend to bid the prices of the factors of production—such as labor or capital—to a single, common price.* Over the past few decades, lower transaction in communication costs have helped create one big global market for many products and services. Businesses can identify and hire workers with skills they need anywhere in the world. If a worker in China can do the same work as an American, then what economists call “the law of one price” demands that they earn essentially the same wages, because the market will arbitrage away differences just as it would for other commodities. That’s good news for the Chinese worker, and for overall economic efficiency. But is not good news for the American worker who now faces low-cost competition. A number of economists have made exactly this argument. Michael Spence, in his brilliant book The Next Convergence, explains how the integration of global markets is leading to enormous dislocations, especially in labor markets.27 The factor price equalization story yields a testable prediction: American manufacturers would be expected to shift production overseas, where costs are lower.

While this was difficult when traders were swapping stocks beneath a buttonwood tree on Wall Street in the eighteenth century, the invention of the telegraph—and the telephone, the high-speed modem, and a grid of orbiting satellites—has made it much easier to accomplish in modern times. Such obvious discrepancies in practice are rare and are often hidden in the depths of the financial markets like gold nuggets in a block of ore. That’s where the quants, the math whizzes, step in. Behind the practice of arbitrage is the law of one price (LOP), which states that a single price should apply to gold in New York as in London, or anywhere else for that matter. A barrel of light, sweet crude in Houston should cost the same as a barrel of crude in Tokyo (minus factors such as shipping costs and variable tax rates). But flaws in the information certain market players may have, technical factors that lead to brief discrepancies in prices, or any number of other market-fouling factors can trigger deviations from the LOP.

Index funds involve passive replication of market characteristics, representing the fund-management world’s version of a pure commodity. The execution of index-fund management requires no particular strategy, depends on no specially trained personnel, and produces no newsworthy track record. After funds under management reach an appropriate scale, size ceases to matter. In contrast to the world of active management, passive management produces a simple story. Economic theory teaches the law of one price, viz., that in freely competitive markets identical goods or services trade at identical prices. In the case of index-fund management, the portfolio management fees charged by various service providers should be identical, or nearly so. Otherwise, rational consumers transfer funds from high-cost providers to low-cost providers, thereby driving the greedy (or inefficient) fund-management companies to reduce prices or exit the business.
