Hardin’s “tragedy of the commons” explained with a practical example: a tourist trap in Florence
Garrett Hardin’s idea of “The Tragedy of the Commons” has become well known, but not always really understood. In my case, I can say that I have big troubles in having my students grasping its mechanism; that is the interplay of individual advantage versus public goods; the basic factor that leads to what we call “overexploitation.”
Perhaps the problem lies in the fact that Hardin used the example of sheep and pastures to explain the reasons of the tragedy, but that’s rather unfamiliar to my students (as well as to most of us). For instance, many of my students don’t seem to be able to grasp the concept of “overgrazing”, that is the fact that grass doesn’t regrow if it is grazed too much. Besides, the pastures that Hardin was considering never experienced the “tragedy”; they were well managed and well regulated, specifically in order to avoid it.
So, let me propose a different example for the mechanism of overexploitation, based on a real event that happened to me. Maybe it can explain the concept better.
Just a few days ago I was literally kidnapped inside an underground parking in Florence because I had lost my entrance ticket, with the employees of the place insisting that they won’t let me out unless I was willing to shell out 237 euros for about two hours of parking (!!).
I described the experience in detail in a post in Italian, that you may machine translate if you are really interested. The gist of the story, anyway, is that I found myself caught in a trap mainly designed to siphon out some money out of the pockets of the hapless foreign tourist passing by. In my case, I was able to negotiate my release and avoid paying the exorbitant surcharge.
