Prince Edward Island is known for the variety of potatoes it produces. You will see many potato stands along the roads in PEI. Payment of goods is by the honour system, where buyers leave their money in a cash box. If just a few people cheated, it would not affect the potato prices, but if too many cheated, then the prices would have to rise. How would you decide whether to pay or to cheat?
