This is your second one, so you know the set up but this is a little different.
Economics is a way of thinking about the world. You are close to having at least 2 courses of instruction of instruction in the subject, so this is more of a personal statement: What have you learned in this class or in all the economics courses you have taken? What did you learn that surprised you? How do you think differently then before, or do you? What do you understand differently or better than before?
It is to be no more than 2 pages, APA formatting (no title page or abstract), this is a personal statement so sources are not necessary but I would expect you to have some so use APA for citing them. Be creative and interesting.
