Supplementary materials for the centralized punishment experiment

Below are supplementary materials for:
    Yoshio Kamijo, Tsuyoshi Nihonsugi, Ai Takeuchi and Yukihiko Funaki.
    "Sustaining cooperation in social dilemmas: Comparison of centralized punishment institutions"

  • Instructions in PDF: REL-L (0.3MB), ABS-L (0.3MB)
    [Note] Originally, the instructions were made with Power-point, so each bullet points appeared in sequences.
    To restrict the file size, we only have uploaded here our PDF version.
    Instructions for Middle and High threshold treatments differ only in the threshold value on page 11, line 2.
  • Control Questions in PDF: REL-L (65KB), ABS-L (65KB)
    Here are understanding tests used in the experiment for the low threshold treatments.
    Other threshold treatments only differ in the value of thresholds in question 6.
  • Data (will be available upon publication)
