Table 1. Experimental conditions and parameters. The parameters are defined in Table 2. IW88 signifies that the data are from Isaac and Walker (1988); IWW94 signifies that the data are from Isaac et al. (1994). In all of these eight experimental conditions, the participating players were experienced in the sense that they had previously participated in another public-good game. Also, cash payments were made in all of the eight conditions. The eight conditions are divided into two subsets: six experimental conditions with 10 rounds and two experimental conditions with 40 and 60 rounds.
