Ego Depletion and the tragedy of the commons

what is ethical consumption and investment
What is Ethical Consumption and Investment?
  • Typically defined: Fair trade, locally sourced, recycled goods, free range, organic…
  • My definition: Favouring products that are for the greater good
  • Most consumers do not consistently buy ethical branded products (Altman, 2001, Thøgersen, 2006)
      • Economic incentives often outweigh moral motives (Fransson & Gärling, 1999,De Pelsmacker et al., 2005)
spending conflict
Spending Conflict
    • Ethical spending can be considered a ‘Social Dilemma’ with two components:
    • Social conflict: Motivationally demanding
    • Temporal conflict: Cognitively demanding
  • Hardin (1968) Tragedy of the commons
    • Some people will only act in accordance with self interest (free ride)
    • Why continue to act morally when others do not?
    • Can we indefinitely resist temptation?
self regulation and ego depletion
Self Regulation and Ego Depletion
  • Self regulation constrains undesirable urges (Alberts et al., 2007)
  • Ensure behaviour is inline with our long term goals
    • Decision making, self-presentation, and intellectual performance (Alberts et al., 2007; Baumeister & Vohs, 2007)
  • Via regulating
    • Thoughts (taking others perspective / Long term impact)
    • Emotions (warm fuzzy feeling vs guilt)
  • Self restraint is a limited cognitive resource (Baumeister et al., 1998)
self regulation and ego depletion1
Self Regulation and Ego Depletion
  • Self-regulation is impaired by prior self-regulation
  • Ego depletion results in self serving attitudes (Hofmann et al., 2007)
  • Ego depletion should lead to self serving and short term economic decisions
  • No study has previously investigated ego depletion at the group level
current study

  • Sheldon and McGregor (2000) forest game
    • 4 players per game 200 hectare forest. Cut down 10 hectares' per player per round
    • Forest regenerates up to 10%
