Balin purchases fair trade cocoa out of concern for workers' rights and environmental sustainability. he could purchase cocoa of equal quality at a lower price.
behavioral economists would consider balin's purchase:

a) unusual in that it demonstrates concern for others.
b) purely self-interested but motivated by something other than his financial well-being.
c) as evidence that balin is not acting purely in his self-interest.
d) a bad decision because it ignores important information that could improve balin's well-being.

In the 10th grade, i was teamed up in a group of four. our project was on modern history. altho it seemed super hard for many of us. patrick fleming  took charge and showed us the understanding of this project.  his leadership showed great ethics and it taught me, personally, how to others understand, not just to show them, but explain it thoroughly. and altho he was a great teacher i would have changed a few things. one being his attitude. many times he would get frustrated and impatient with the group.  i think  a leader i would have done exactly  what he did but with much more patience and be there more to explain. such as lunch  learning. and giving everybody a chance to try to explain it in their  head.
