Original electronic Scanned image These products were created by scanning an original printed edition.
Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable.
Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background. For printed books, we have performed high-resolution scans of an original hardcopy of the book.
We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format These ebooks were created from the original electronic layout files, and therefore are fully text searchable.
Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality. File Last Updated:. This title was added to our catalog on February 15, See all titles Need help?

And Dick? They must have questioned hundreds of men, and no doubt accused dozens; he and Dick were merely two more….
And Dick, awake in a cell on the floor below, was he later recalled equally eager to converse with Perry—find out what the punk had told them. Eventually Dick confessed and then Perry. The problem is, who will risk his life to bell the cat? This is a problem for both mice and men. How can unpopular tyrants control large populations for long periods? Why can a lone bully terrorize a schoolyard? In both cases, a simultaneous move by the masses stands a very good chance of success.
But the communication and coordination required for such action is difficult, and the oppressors, knowing the power of the masses, take special steps to keep it difficult. His reward may be posthumous glory or gratitude. There are people who are moved by considerations of duty or honor, but most find the costs exceed the benefits. After his dramatic speech, someone in the audience shouted out, asking what Khrushchev had been doing at the time.
Khrushchev responded by asking the questioner to please stand up and identify himself. The audience remained silent. We should emphasize right from the start that we have no presumption that the outcome of a game will be good for the players. Many economists, ourselves included, tout the advantages of the free market.
The theory behind this conclusion relies on a price system that guides individual behavior. In most strategic interactions, there is no invisible hand of prices to guide the baker or the butcher or anyone else. Thus there is no reason to expect that the outcome of a game will be good for the players or society.
It may not be enough to play a game well—you must also be sure you are playing the right game. Rather than choose one over the other, he suggested the two of them play a game of Rock Paper Scissors to determine the winner. Yes, Rock Paper Scissors. Rock breaks scissors, scissors cuts paper, and paper covers rock. With the stakes so high, could game theory have helped? No matter what you choose, there is something else that beats it. Since they were beginners, scissors was definitely the safest.
They thought this was simply a game of chance and hence there was no room for strategy. Paper was as good as anything else. What is interesting here is that both sides were half right. Each option has a one- third chance of winning, a one-third chance of losing, and a one-third chance of a tie. In that sense, both players got it half wrong.
But when games get repeated, the approach is trickier. Mixing your plays does not mean rotating your strategies in a predictable manner. Your opponent can observe and exploit any systematic pattern almost as easily as he can exploit an unchanging repetition of a single strategy. It is unpredictability that is important when mixing. It turns out most people fall into predictable patterns. People are also too influenced by what the other side did last time.
Imagine what would happen if there were some known formula that determined who would be audited by the IRS. Before you submitted a tax return, you could apply the formula to see if you would be audited. If an audit was unavoidable, you would choose to tell the truth. The result of the IRS being completely predictable is that it would audit exactly the wrong people. All those audited would have anticipated their fate and chosen to act honestly, while those spared an audit would have only their consciences to watch over them.
When the IRS audit formula is somewhat fuzzy, everyone stands some risk of an audit; this gives an added incentive for honesty. The importance of randomized strategies was one of the early insights of game theory.
The idea is simple and intuitive but needs refinement to be useful in practice. He needs some idea of whether he should go to the forehand 30 percent or 64 percent of the time and how the answer depends on the relative strengths of the two sides.
In chapter 5 we develop methods to answer such questions. His decision to deploy Rock Paper Scissors gave each of the two auction houses a 50 percent chance of winning the commission. Instead of letting the two contestants effectively agree to split the commission, he could have run his own auction. Both firms were willing, even eager, to lead the sale with a 12 percent commission.
Do I hear 11 percent? Going once, going twice,…. One of these days in your travels, a guy is going to show you a brand-new deck of cards on which the seal is not yet broken. Then this guy is going to offer to bet you that he can make the jack of spades jump out of this brand- new deck of cards and squirt cider in your ear. Nathan had just discovered the answer strudel and is willing to bet if Sky will bet on cheesecake. Of course no one would take such a sucker bet. Or would they?
Look at the market for futures contracts on the Chicago Board of Exchange. If another speculator offers to sell you a futures contract, he will make money only if you lose money.
Similarly, if you sell soy milk and hence need to buy soy beans in the future, this contract is insurance, not a gamble. But the volume of the contracts on the exchange suggests that most people buying and selling are traders, not farmers and manufacturers. For them, the deal is a zero-sum game. When both sides agree to trade, each one thinks it will make money. One of them must be wrong. This is a paradox. How can both sides think that they can outsmart the other?
Someone must be wrong. Why do you think the other person is wrong, not you? If someone is willing to sell you a futures contract, any money you make is money they lose. Why do you think that you are smarter than they are? Remember that their willingness to trade means that they think they are smarter than you. In poker, players battle this paradox when it comes to raising the stakes.
If a player bets only when he has a strong hand, the other players will soon figure this out. Those who raise back will have even stronger hands, and so our poor player will end up a big loser. To get others to bet against a strong hand, they have to think you might be bluffing. To convince them of this possibility, it helps to bet often enough so that you must be bluffing some of the time.
This leads to an interesting dilemma. To convince others to raise your bets, you also need to get caught bluffing. As the players get even more sophisticated, persuading others to take big bets against you becomes harder and harder. It was like a step above. For similar reasons, you might not want to take any bet that others offer. You should even be worried when you win an auction. The very fact that you were the highest bidder implies that everyone else thought the item was worth less than you did.
There are some rules of the game that can help put you on more equal footing. One way to allow trading with lopsided information is to let the less informed party pick which side of the bet to take. In stock markets, foreign exchange markets, and other financial markets, people are free to take either side of the bet.
Indeed, in some exchanges, including the London stock market, when you ask for a quote on a stock the market maker is required to state both the buying and selling prices before he knows which side of the transaction you want. The buy and sell prices are not quite the same; the difference is called the bid-ask spread.
In liquid markets the spread is quite small, indicating that little information is contained in any buy or sell order. We return to the role of information in chapter 8. Immediately recognizing us as American tourists, the driver refused to turn on his meter; instead, he proclaimed his love for Americans and promised us a lower fare than the meter.
Naturally, we were somewhat skeptical of this promise. Why should this stranger offer to charge less than the meter when we were willing to pay the metered fare?
How would we even know whether or not we were being overcharged? On the other hand, we had not promised to pay the driver anything more than what would be on the meter.
We put on our gametheory hats. If we were to start bargaining and the negotiations broke down, we would have to find another taxi. But if we waited until we arrived at the hotel, our bargaining position would be much stronger.
And taxis were hard to find. We arrived. Who knew what fare was fair? Because people generally bargain in Israel, Barry protested and counteroffered 2, shekels. The driver was outraged. He claimed that it would be impossible to get from there to here for that amount. Were we being kidnapped to Beirut?
This driver turned on his meter, and 2, shekels later we were home. Certainly the extra time was not worth the shekels. On the other hand, the story was well worth it. It illustrates the dangers of bargaining with those who have not yet read our book. More generally, pride and irrationality cannot be ignored. Sometimes, it may be better to be taken for a ride when it costs only two dimes.
There is a second lesson to the story. Think of how much stronger our bargaining position would have been if we had begun to discuss the price after getting out of the taxi.
Of course, for hiring a taxi, this logic should be reversed. If you tell the driver where you want to go before getting in, you may find your taxi chasing after some other customer. Get in first, then say where you want to go. Some years after this story was first published, we received the following letter:. I was a student in Jerusalem moonlighting as a taxi driver. Now I am a consultant and chanced upon your book when it was translated into Hebrew.
What you might find interesting is that I too have been sharing the story with my clients. Yes, it was indeed a late night in Jerusalem. As for the rest, well, I recall things a bit differently. Between classes and working nights as a taxi driver, there was almost no time for me to spend with my new bride.
My solution was to have her ride with me in the front seat. Although she was silent, it was a big mistake for you to have left her out of the story. I was too tired to argue. When we arrived, I asked for 2, shekels, a fair price. I was even hoping you would round the fare up to 3, Your refusal to pay a fair price dishonored me in front of my wife.
Americans think that we should be happy to take whatever crumbs you offer. I say that we should teach you a lesson in the game of life. My wife and I are now married twenty years.
We still laugh about those stupid Americans who spent a half an hour riding back and forth in taxis to save twenty cents. Sincerely, name withheld. Truth be told, we never received such a letter. You need to consider what they know, what motivates them, and even how they think about you. When thinking strategically, you have to work extra hard to understand the perspective and interactions of all the other players in the game, including ones who may be silent.
That brings us to one last point. You may be thinking you are playing one game, but it is only part of a larger game.
There is always a larger game. Think 48 when you are wondering what the other player is trying to achieve. Therefore, we cannot assume that when we change our behavior everything else will remain unchanged. That stubborn adversary might well be your future self, especially when it comes to dieting. Fighting or dieting with your back up against the wall can help strengthen your resolve.
In Cold Blood and the story of belling the cat demonstrate the difficulty of obtaining outcomes that require coordination and individual sacrifice.
In technology races, no less than in sailboat races, those who trail tend to employ more innovative strategies; the leaders tend to imitate the followers. Rock Paper Scissors points out the strategic advantage of being unpredictable. Such behavior may also have the added advantage that it makes life just a little more interesting. Our taxi rides make it clear that the other players in games are people, not machines.
Pride, spite, and other emotions may color their decisions. We could go on offering more examples and drawing morals from them, but this is not the best way to think methodically about strategic games.
That is better done by approaching the subject from a different angle. We pick up the principles—for example, commitment, cooperation, and mixing—one at a time. In each instance, we explore examples that bear centrally on that issue, until the principle is clear. Then you will have a chance to apply that principle in the case study that ends each chapter. Which of the following is the correct answer?
Still, we think that by putting on your gametheory hat you can still figure it out. Case Discussion The odd answer in the series is c. Since it is so different from the other answers, it is probably not right. Think of the game being played by the person writing the question. Turning this around, imagine that 16 square inches really is the right answer.
Not many. Hence we can truly rule out 16 as being the correct solution. The problem might have been what is the area of a circle with a radius of 4? Yes, we know that the circumference is in inches, not square inches, but the person making this mistake would be unlikely to recognize this issue.
They are all good wrong answers for the test maker. At this point, we are done. And we are right. By thinking about the objective of the person writing the test, we can suss out the right answer, often without even seeing the question. We appreciate that if you are smart enough to go through this logic, you most likely know the formula for the area of a circle.
But you never know. In those cases, thinking about the testing game may lead you to the right answer. At the last moment, Lucy pulls the ball away.
Charlie Brown, kicking only air, lands on his back, and this gives Lucy great perverse pleasure. Even if Lucy had not played this particular trick on him last year and the year before and the year before that , he knows her character from other contexts and should be able to predict her action. However, just because it lies in the future does not mean Charlie should regard it as uncertain.
Therefore he should forecast that when the time comes, she is going to pull the ball away. The logical possibility that Lucy will let him kick the ball is realistically irrelevant. Reliance on it would be, to borrow Dr. Charlie should disregard it, and forecast that acceptance will inevitably land him on his back. These interactions arise in two ways. The first is sequential, as in the Charlie Brown story. The players make alternating moves.
Charlie, when it is his turn, must look ahead to how his current actions will affect the future actions of Lucy, and his own future actions in turn. However, each must be aware that there are other active players, who in turn are similarly aware, and so on. Therefore each must figuratively put himself in the shoes of all and try to calculate the outcome. His own best action is an integral part of this overall calculation. When you find yourself playing a strategic game, you must determine whether the interaction is simultaneous or sequential.
Some games, such as football, have elements of both, in which case you must fit your strategy to the context. In this chapter, we develop, in a preliminary way, the ideas and rules that will help you play sequential games; simultaneous-move games are the subject of chapter 3. We begin with really simple, sometimes contrived, examples, such as the Charlie Brown story. This is deliberate; the stories are not of great importance in themselves, and the right strategies are usually easy to see by simple intuition, allowing the underlying ideas to stand out much more clearly.
The examples get increasingly realistic and more complex in the case studies and in the later chapters. This idea is so important that it is worth codifying into a basic rule of strategic behavior:.
Anticipate where your initial decisions will ultimately lead and use this information to calculate your best choice. In the Charlie Brown story, this was easy to do for anyone except Charlie Brown.
Most strategic situations involve a longer sequence of decisions with several alternatives at each. A tree diagram of the choices in the game sometimes serves as a visual aid for correct reasoning in such games.
Let us show you how to use these trees. For Robert Frost in the yellow wood:. Two roads diverged in a wood, and I— I took the road less traveled by, And that has made all the difference. This need not be the end of the choice. Each road might in turn have further branches. The road map becomes correspondingly complex. Here is an example from our own experience. Travelers from Princeton to New York have several choices. The first decision point involves selecting the mode of travel: bus, train, or car.
Once in New York, rail and bus commuters must choose among going by foot, subway local or express , bus, or taxi to get to their final destination. For example, if you want to go downtown, the PATH train would be superior to driving because it offers a direct connection from Newark.
We can use just such a tree to depict the choices in a game of strategy, but one new element enters the picture. A game has two or more players. At various branching points along the tree, it may be the turn of different players to make the decision. A person making a choice at an earlier point must look ahead, not just to his own future choices but to those of others.
He must forecast what the others will do, by putting himself figuratively in their shoes, and thinking as they would think. To remind you of the difference, we will call a tree showing the decision sequence in a game of strategy a game tree, reserving decision tree for situations in which just one person is involved. Start the game when Lucy has issued her invitation, and Charlie faces the decision of whether to accept.
If Charlie refuses, that is the end of the game. If he accepts, Lucy has the choice between letting Charlie kick and pulling the ball away. We can show this by adding another fork along this road. As we said earlier, Charlie should forecast that Lucy will choose the upper branch. Therefore he should figuratively prune the lower branch of her choice from the tree. Now if he chooses his own upper branch, it leads straight to a nasty fall. Therefore his better choice is to follow his own lower branch.
We show these selections by making the branches thicker and marking them with arrowheads. Are you thinking that this game is too frivolous? Here is a business version of it. Imagine the following scenario. Charlie, now an adult, is vacationing in the newly reformed formerly Marxist country of Freedonia. So you will more than double your money in a year.
But how secure is that law? If at the end of the year Fredo absconds with all the money, can Charlie, back in the United States, enforce the contract in Freedonian courts?
They may be biased in favor of their national, or too slow, or bribed by Fredo. So Charlie is playing a game with Fredo, and the tree is as shown here. What do you think Fredo is going to do? In the absence of a clear and strong reason to believe his promise, Charlie should predict that Fredo will abscond, just as young Charlie should have been sure that Lucy would pull the ball away. In fact the trees of the two games are identical in all essential respects.
But how many Charlies have failed to do the correct reasoning in such games? Perhaps he is engaged in many other enterprises that require financing from the United States or export goods to the United States. Then Charlie may be able to retaliate by ruining his reputation in the United States or seizing his goods.
But in the one-time version we showed above, the logic of backward reasoning is clear. We would like to use this game to make three remarks. First, different games may have identical or very similar mathematical forms trees, or the tables used for depictions in later chapters. Thinking about them using such formalisms highlights the parallels and makes it easy to transfer your knowledge about a game in one situation to that in another. Many people have an instinctive aversion to theory of any kind.
But we think this is a mistaken reaction. Of course, theories have their limitations. Specific contexts and experiences can often add to or modify the prescriptions of theory in substantial ways. But to abandon theory altogether would be to abandon a valuable starting point for thought, which may be a beachhead for conquering the problem. You should make game theory your friend, and not a bugbear, in your strategic thinking.
