Haowen Zheng Econ Writing Assignment #1 2.9.2011 Why students save seats for themselves and their friends In Cornell University, we can always see some students get up early and save seats for themselves, sometimes even for their roommates or their friends.

But the marginal benefit is large. Your friend will be grateful for your action and think of you as an attentive person. You may also receive some certain kind of rewards from your friend as a result of your act. Because the marginal benefit is much larger than the marginal cost so people would like to save seats for their friends.
