For example, if you are out of shape you may consider the marginal costs and benefits of exercises. On the one hand, you will receive a benefit from working out today. On the other hand, it will take some pain and effort. It is up to you to decide whether the marginal benefit or cost is greater. If everyone acts in a manner that most...
