Hitting the word count for a given assignment can sometimes be tough. If your teacher or professor set a particular page count, he or she probably did so for a reason. In all likelihood, it would be difficult to do a good job going under the required page count. Therefore, if your essay is on the short side, there's probably room to expand the content. Read over your essay and be critical of your writing. Look for moments and paragraphs where additional facts, resources, and quotations may be needed. Then, go in and add this information to your essay. With a little time and dedication, you should be able to stretch your essay out to the proper page count.
Much research has focused on when and why people would like to structurally rearrange the commons to prevent a tragedy. Hardin stated in his analysis of the tragedy of the commons that "Freedom in a commons brings ruin to all."  One of the proposed solutions is to appoint a leader to regulate access to the common. Groups are more likely to endorse a leader when a common resource is being depleted and when managing a common resource is perceived as a difficult task. Groups prefer leaders who are elected, democratic, and prototypical of the group, and these leader types are more successful in enforcing cooperation. A general aversion to autocratic leadership exists, although it may be an effective solution, possibly because of the fear of power abuse and corruption.
In other situations, though, lose-lose outcomes occur when win-win outcomes might have been possible. The classic example of this is called the prisoner's dilemma in which two prisoners must decide whether to confess to a crime. Neither prisoner knows what the other will do. The best outcome for prisoner A occurs if he/she confesses, while prisoner B keeps quiet. In this case, the prisoner who confesses and implicates the other is rewarded by being set free, and the other (who stayed quiet) receives the maximum sentence, as s/he didn't cooperate with the police, yet they have enough evidence to convict. (This is a win-lose outcome.) The same goes for prisoner B. But if both prisoners confess (trying to take advantage of their partner), they each serve the maximum sentence (a lose-lose outcome). If neither confesses, they both serve a reduced sentence (a win-win outcome, although the win is not as big as the one they would have received in the win-lose scenario).
