In this game you will be assigned to a group of eight and participate in this same group for 5 periods. In each period, each person can decide how much effort to put into extracting some common resource. Each person can put up to 20 units of effort into resource extraction. The benefit that your effort yields will depend on the extraction decisions of the other 7 individuals.
Specifically, the total yield from extraction is given by 11(total effort) – 1/16(total effort)^2. The graph of this function is shown below.
