In 1968, Garrett Hardin first introduced a new framework to specify situations in which consumption of goods increases short-term utility of individuals while creating a long-term dead-weight loss in total welfare at the same time. He defines these situation in the following way: “The tragedy of the commons is a dilemma arising from the situation in which multiple individuals, acting independently and rationally consulting their own self-interest, will ultimately deplete a shared limited resource, even when it is clear that it is not in anyone's long-term interest for this to happen (Hardin, 1968).” Hardin proposes enclosure of these commons, a redefinition of property rights. Either a person owns his own land or someone is given ownership to the whole to manage the resource and distribute usage against compensation. The tragedy of the commons is related mainly to the acquaintance of Global public goods, which leads to the question how these can be defined in context to the framework of ecological crisis in todays world. Since 1968, there is an increasing number of academic research about how to deal with the commons, some agreeing to Hardin, others deviating from his standpoint. The question arises whether the key-arguments and assumptions within Hardins “the tragedy of the commons” are correct and in what way Hardin's work restricts options when dealing with the ecological crisis.
In order to specify situations, in which the “tragedy of the commons” or alternative frameworks dealing with the commons can be applied, the paper first defines global public goods and introduces different kinds of commons. Secondly, Hardin's argumentation is summarized in a practical example via game theory. By revealing the primary motivations in decision-making as well as the final payoff-structure of individuals and society, Hardins assumption and hypothesis become much clearer. These arguments are then individually revisited and complemented by approaches taken from other research results. Finally, real-life examples will paint a picture about which approaches...
