  11. cooperatives as a model organization • all organizations require cooperation

    • cooperation central to human uniqueness • cooperatives fundamentally depend cooperation • positive social externalities • emerge in harsh economic conditions

  23. interviews Natasha’s Story: • founder and leader of a buying

    club (using buyingclubsoeware) • club lasted: 2009 - 2015 • she remained leader, 4-6 hrs/wk • 3 roles grew to 15 jobs, more coopera=on with larger size • open door policy too costly • “had to make joining harder” -> caused club to shrink • personality fric=on, differing visions, bending of rules • kids, space -> Natasha leaves, 1yr later it’s dead 1-Free-riding is observable. 2-Free-riding might have caused failure.
  24. Survey - 9 buyingclubsoftware.com clubs - 98 participants - 3.5

    months: Nov 2016 - Mar 2017 - 25-70 questions (members & coordinators) - Perceptions & experience - Preferences & satisfaction - Club history, organization & operation - Demographics Design & Implementa,on
  25. Survey Results Ordering - 54.3% purchases shared - 71% of

    purchases were local - 50% of coordinators believe more sharing would benefit the group Preferences - 33% joined to save money on food - 84% joined to support local producers Demographics - Mean HH income: 65,000, HH size: 3 - 63% bachelor’s or higher - 95% female
  26. Frequency of helping others via split purchases. Mean = 60%

    Frequency of receiving help via split orders. Mean = 47% helping getting help

  31. Results (means) Mean dictator donation: 58% of endowment 107% increase

    from typical (Engel, 2011) Mean public goods donation: 66% of endowment 74% increase from typical (Zelmer, 2003) Elevated levels of cooperation when compared to other study populations

  33. Buying Club Simula,ons Can the success or failure of buying

    clubs be explained by generalized reciprocity between members in split purchases?
  34. ! Cooperation maintained by reciprocity (Trivers, 1971). ! Generalized reciprocity

    between members on shared purchases (splits) ! Preferences vary, requires cooperation. ! Agents record the ratio of the help they’ve received versus given. ! Use ratio to determine two choices: help/don’t, and stay/leave Buying Club Simulations
  35. social network analysis ! Order data: who bought what !

    Orders occur every week to every month ! 2012 - 2017 ! 27 Buying Clubs ! Clubs range from 10 to 150 members
  36. Social Network Analysis What characterizes the splitting networks of successful

    or failing clubs? Are there structural early warning signs of failure?
  37. Is there split threshold below which clubs die? Can high

    split ratios be sustained? Buying Club Purchase Data
  38. 1. Evolu=onary approach is useful for understanding organiza=onal change (coopera=on,

    diversifica=on, adapta=on). 2. All organiza=ons rely on coopera=on & human prosocial ins=ncts. 3. Coopera=ves are a good model organiza=on because they are vulnerable to the challenge of coopera=on. 4. Coopera=ves may be considered the ancestral human organiza=on. Evolu,on of organiza,ons
  39. 1. Coopera=ves rely on coopera=on more than other types of

    organiza=on. 2. Free-riding is a perpetual problem for coopera=ves. 3. Successful coopera=ves have ins=tu=onal adapta=ons which help solve the free-rider problem. 4. The coopera=ve principles are (were?) and example of such an adapta=on. 5. Coopera=ves tend to be out-competed by compe=tors with fewer internal challenges. 6. Coopera=ves tend to emerge in harsh economic environments because that’s how humans solve problems. Evolu,on of coopera,ves
