Pollution Game You, along with many others, value clean air. In fact, clean air is worth 100 to you. The amount of clean air that you get is determined by yourself and others. In particular, the amount of clean air that you get is precisely equal to 100 p where p is the proportion of your community that chooses to buy pollution control equipment. For example, if half of your community chooses to buy pollution control equipment, then you will receive 100p = 50. There is no free lunch. Pollution control equipment costs 20. If you choose to buy pollution control equipment, 20 points will be subtracted from the value (or amount) of clean air that you receive to obtain your raw score. For example, if you choose to buy pollution control equipment and 40% of your community also buys pollution control equipment, then you will receive 40 20 = 20 points (and 20 would be your raw score). If you elect not to buy pollution control equipment and say 35% of your community buys pollution control equipment, then you will receive 35 0 = 35 points (so 35 is your raw score).
