what is thinking on the margin
The third pillar is Economic thinking is thinking on the margin.. I find that this is the toughest of the 10 pillars for my students to grasp. But once they get it, it changes how they think about many things in life. Most issues in economics and in life are not all or nothing, but more or less. That's where thinking on the margin comes in. So, for example, I assert that if gasoline prices rise by 50 percent due to a reduction in supply, many people will drive less. When some people hear that statement, they react, thinking that they are disagreeing, with comments like I would still drive to work..
