  1. Module 1:Evolution and Economics The Development of Economic Systems

  2. From an Evolutionary Perspective… • Isolate the basic biological aspects. • Explore how it has been altered throughout a species’ (our) evolutionary heritage.

  3. economics 2. The branch of knowledge (now regarded as one of the social sciences) that deals with the production, distribution, consumption, and transfer of wealth; the application of this discipline to a particular sphere; (also) the condition of a state, etc., as regards material prosperity; the financial considerations attaching to a particular activity, commodity, etc.

  4. Evolutionary Game Theory

  5. Game Theory and Biology:Optimal Foraging Theory ?

  6. Game Theory and Biology:Optimal Foraging Theory E = 500 cal. T = 15 min. E = 250 cal. T = 5 min. ?

  12. Game Theory and Biology:One-on-One Interactions • John Maynard Smith: • Hawk-Dove Models

  13. D H ½ Food D H

  15. D H ½ Food Nada D Food H

  16. D H ½ Food Nada D ½ Food Minus Cost Food H

  17. Relative Fitness • Graph

  18. Game Theory and Biology:One-on-One Interactions • Tit-for-Tat strategy cooperates with cooperators and defects on defectors.

  19. T H ½ Food T H

  20. T H ½ Food Minus Cost ½ Food T H

  21. D H ½ Food Minus Cost ½ Food D ½ Food Minus Cost H

  22. D H ½ Food Minus Cost ½ Food D ½ Food Minus Cost ½ Food Minus Cost H

  23. Relative Fitness

  24. Tit-for-Tat in Nature:Birds

  25. Tit-for-Tat in Nature:Fish

  26. Tit-for-Tat in Nature:Primates

  27. Game Theory and Biology:Why Begin Cooperating? E = 4000 cal. T Alone = N/A T w/Help = 30 min. E = 500 cal. T = 20 min. ?

  28. Game Theory and Biology:Why Begin Cooperating?

  29. Game Theory and Biology:Why Begin Cooperating?

  30. Game Theory and Biology:Why Begin Cooperating?

  31. Cooperation and Culture

  32. Evolutionary Game Theory:Ultimatum Game Player 1 Player 2 Or Player 2 can refuse the offer, and no one gets any money. Player 1 can then give as much or as little of the money as he or she wants to Player 2. Player 2 can approve of the amount given, and both keep the money.

  33. Quichua • Individual farmers of the Amazon Basin.

  34. Lamalera • Whale hunters from Indonesia.

  35. Kazakh • Pastors of Mongolia.

  36. Au and Gnau • Foraging peoples from New Guinea.

  37. What Explains the Variation? Social Dependency Social Integration

  38. Make CBG-Only Map

  39. Using the Sequential Prisoner's Dilemma • First Mover: Plays “blindly” • Second Mover: Plays with knowledge of first mover’s behavior.

  40. Using the Sequential Prisoner's Dilemma • 1) How would you play as a first mover? • 2) How would you play as a second mover if your partner cooperated? • 3) How would you play as a second mover is your partner did not cooperate?

  41. Predictors of Cooperation:A World in a City Social Dependency Inverse of Median Income Social Integration N’bhd Quality

  42. Cooperation and Subcultures

  43. Predictors of Cooperation:In-Class Study #1 Social Dependency Risk Taking Behavior Social Integration Trusting People

  44. How to Maintain Cooperation?

  45. How to Maintain Cooperation?

  46. How to Maintain Cooperation?

  47. How to Maintain Cooperation?

  48. How to Maintain Cooperation?:Imitation

  49. How to Maintain Cooperation?:Punishment

  50. How to Maintain Cooperation?:Punishment • Moralistic Punishers • Prosocial individuals who also punish. • Selfish Punishers • Individuals who are generally selfish but punish other selfish individuals.
