Experimental games help communities explore solutions
2019
The results of our games show that farmers act less selfish
than theory predicts. Nevertheless, even in the presence
of transparent decisions and repeated possibilities to
discuss, groups manage to produce enough water for
everyone to grow crops only in approximately 50% of the
played rounds. The red line in Figure 3 indicates the social
optimal investment level in our game. At this level, all
players of a particular group could grow the water-efficient
rabi (postrainy) crop (chickpea). Still, in 15% of the crop
decisions in the game, players decided to grow the waterintensive crop (wheat). It was very transparent in the
design of our game that this was an uncooperative action.
