1. How To Do Exactly the Right Thing at All Possible Times or Nothing ____ ^ The Idea That Changed the World

2. E(u | p, X) = xX p(x)u(x)

3. E(u | p, X) = xX p(x)u(x) Expected Value = (Odds of Gain) X (Value of Gain)

4. If it comes up heads I’ll give you \$10. Should you pay \$4 to play? Yes! Expected Value = (Odds of Gain) X (Value of Gain) 1/2 X\$10 = \$5

5. Errors in Odds Errors in Value Expected Value = (Odds of Gain) X (Value of Gain)

6. Errors in Odds Errors in Odds Errors in Value Expected Value = (Odds of Gain) X (Value of Gain)

7. Errors in Odds Are there more dogs or pigs on leashes in Oxford?

15. Errors in Odds Errors in Odds ? • 10 tickets • \$1 to play • \$20 if you win

16. Errors in Odds Errors in Odds 1/10 X \$20 = \$2

17. Errors in Odds Errors in Odds 1/10 X \$20 = \$2

18. Errors in Value Errors in Odds Errors in Value Expected Value = (Odds of Gain) X (Value of Gain) Is this Big Mac worth \$25?

19. Errors in Value: Comparing with the Past COMPARING WITH the Past instead of the Possible

20. Errors in Value: Comparing with the Past \$150K \$60K in Year 1 \$50K in Year 2 \$40K in Year 3 \$135K \$35K in Year 1 \$45K in Year 2 \$55K in Year 3

21. Errors in Value: Comparing with the Past A \$2000 Hawaiian vacation package is on sale for \$1600. Would you buy it?

22. Errors in Value: Comparing with the Past A \$2000 Hawaiian vacation package is on sale for \$700. You think it over for a week, and by the time you get to the ticket agency, the best fares are gone and the package will now cost you \$1500. Would you buy it?

23. Errors in Value: Comparing with the Past Yes \$2000 \$1600 No \$2000 \$700 \$1500

24. Errors in Value: Comparing with the Past You are on your way to the theatre. In your wallet you have a ticket for which you paid \$20, and a \$20 bill. When you arrive at the theatre you discover that you’ve somehow lost the ticket. Would you spend your remaining \$20 on a ticket? No

25. Errors in Value: Comparing with the Past You are on your way to the theatre. In your wallet you have two \$20 bills. When you arrive at the theatre you discover that you’ve somehow lost one of the bills. Would you spend your remaining \$20 on a ticket? Yes

26. Errors in Value: Comparing with the Past The Lost Ticket The Lost Money X X

27. Errors in Value COMPARING WITH the Past instead of the Possible COMPARING WITH the Possible instead of the Past

28. Errors in Value: Comparing with the Possible

29. Errors in Value: Comparing with the Possible \$8.00 \$27.00 \$33.00

30. Errors in Value: Comparing with the Possible \$8.00 \$27.00 \$33.00 \$51.00

31. Errors in Value: Comparing with the Possible

32. Errors in Value: Comparing with the Possible You want to buy a car stereo. The dealer near your house sells it for \$200, but if you drive across town, you can get it for \$100. Would you drive to get 50% off (saving \$100)? Yes

33. Errors in Value: Comparing with the Possible You want to buy a car with a stereo. The dealer near your house sells it for \$31,000, but if you drive across town, you can get it for \$30,900. Would you drive to get .003% off (saving \$100)? No

37. Errors in Value: Comparing with the Possible • More is better than less  \$60 NOW \$50 NOW Problem #1

38. Errors in Value: Comparing with the Possible \$60 In 1 month \$60 NOW OR Problem #2

39. Errors in Value: Comparing with the Possible • Now is better than later  \$60 In 1 month \$60 NOW Problem #2

40. Errors in Value: Comparing with the Possible Now is better than later More is better than less BUT \$60 In 1 month \$50 NOW OR Problem #3

41. Errors in Value: Comparing with the Possible Now is better than later More is better than less  \$60 In 1 month \$50 NOW Impatience Problem #3

42. Errors in Value: Comparing with the Possible Now is better than later More is better than less  \$60 In 1 month \$50 NOW Impatience \$50 In 12 months \$60 In 13 months OR

43. Errors in Value: Comparing with the Possible Now is better than later More is better than less  \$60 In 1 month \$50 NOW Impatience  \$50 In 12 months \$60 In 13 months Patience
