11. A Preliminary Question  Who cares if we enforce contracts?  The nihilism of the 1970s: What’s wrong with this contract? “If one person does not lose, the other does not gain.” Augustine The rise of consumerism 10

12. 11 So why enforce contracts?  Casebook suggests two principles The Efficiency Norms of Law and Economics An “Autonomy Principle”  Vas ist das?

13. Autonomy  My personal freedom expands when I have the freedom to bind myself Rousseau: people must be forced to be free Now: must people be free to be forced?  They can only be subject to contractual fetters if the institutions of promising and contract law exist

14. Autonomy  So why is it desirable that promissory institutions exist? Can’t breach a contract without them

15. Autonomy  So why is it desirable that promissory institutions exist? Can’t breach a contract without them And I can’t slide home without the game of baseball So how to come up with an argument for either institution, without attributing some outside value to the game? Suppose it was shown that contractual enforcement made everyone miserable?

16. Could promising exist without promissory institutions? 15 The Kingdom of Tonga

17. The Queen of Tonga With the Queen Mother at the Coronation, 1953 16

18. The Queen of Tonga With her Prime Minister, Coronation 1953 17

19. Tonga Where People Don’t Promise  There is no word for “promise” in Tonganese  “I intend to do x, but if I change my mind, well, then was then, now is now.” 18

20. Tonga Where People Don’t Promise  There is no word for “promise” in Tonganese  “I intend to do x, but if I change my mind, well, then was then, now is now.”  In such a place, is an autonomy analysis of promises intelligible? 19

21. David Hume 20 “A promise is not intelligible naturally, nor antecedent to human conventions.”

22. Hume didn’t think that all morality is conventional  Non-conventional Natural vs. Conventional Artificial duties  Can you suggest some examples of non-conventional rules? 21

23. Some examples of non- conventional rules?  Consider: “You think that killing x is wrong, but that’s just because you have a convention that x count as people.”  Is that persuasive? 22

24. Promising, on the other hand, rests on a language convention  How could I will myself to be bound by a promise in Tonga?  Hume: There is no mental act that creates an obligation, or that need accompany it. 23

25. Promising, on the other hand, rests on a language convention  Which raises the question: Are such institutions desirable?  If so, we have an answer why people should perform their promises  Otherwise they would subvert a valuable institution 24

26. Promising, on the other hand, rests on a language convention  So just what is the benefit afforded by promissory institutions? A greater assurance of performance  Which is strengthened when contractual sanctions are added to moral ones. 25

27. 26 Does the sanction provided by promissory institutions suffice?  Men being naturally selfish, or endow'd only with a confin'd generosity, they are not easily induc'd to perform any action for the interest of strangers, except with a view to some reciprocal advantage

28. 27 Contracts in the State of Nature Hobbes, Leviathan 14.18 (1651)  If a covenant be made wherein neither of the parties perform presently, but trust one another, in the condition of mere nature (which is a condition of war of every man against every man) upon any reasonable suspicion, it is void…  For he that performeth first hath no assurance the other will perform after, because the bonds of words are too weak to bridle men's ambition, avarice, anger, and other passions, without the fear of some coercive power; which in the condition of mere nature, where all men are equal, and judges of the justness of their own fears, cannot possibly be supposed. And therefore he which performeth first doth but betray himself to his enemy.

29. 28 The Prisoners’ Dilemma Hobbes’ Insight  A simple game that has become the dominant paradigm for social scientists since it was invented about 1960.  How the game works – and why didn’t it work for Dilbert

30. 29 PD games help to explain why we do dumb things  Over-fish lakes and oceans  Pollute  Arms race  Fail to exploit bargaining gains

31. 30 Modeling PD games  Game theoretic problems: payoffs for each player depend on actions of both

32. 31 Hollywood gets in the act Russell Crowe as John Nash in “A Beautiful Mind”

33. 32 The need for poetic license

34. 33 Modeling PD games  Game theoretic problems: payoffs for each player depend on actions of both  Two possible strategies: A party cooperates when he performs value- increasing promises, and defects when he breaches

49. 48 The possibility of defection destroys trust Your corn is ripe today, mine will be so tomorrow… (Hume’s Treatise III.ii.V)

50. 49 The paradox of the PD game  While cooperation is collectively rational, defection is individually rational.  The undersupply of cooperation is “the tragedy of the commons.” Garrett Hardin, The Tragedy of the Commons (1968).

Don't whisper anything you can smile. Don't smile anything you can nod. Don't nod anything you can wink." "I can make them voting machines sing Home Sweet Home."

63. 62 An application: Marriage Rembrandt, The Jewish Bride 1666 But it’s less than a contract if the parties have unilateral exit rights under no-fault divorce laws

70. 69 The Market for Lemons What would you pay?  Of the remaining 1956 Fords, half are worth nothing (“lemons”) and the other half are worth $5000 (“beauts”)  The seller knows which kind of car he has but you can’t tell them apart  What would you pay?

72. 71 The Market for Lemons What would you pay?  Of the remaining 1956 Fords, half are worth nothing (“lemons”) and the other half are worth $5000 (“beauts”)  The seller knows which kind of car he has but you can’t tell them apart  Question: Is the seller satisfied with this result?

73. 72 Contract Law as a solution  Suppose that the defector is penalized through legal sanctions so that the incentive to defect disappears.
