Economics= Art?

Today in class we discussed the concept of Marginal Utility when it comes to art. Marginal utility and Marginal Satisfaction are two terms that mean increasing or decreasing satisfaction or pleasure. I am familiar with these terms from my high school economics class and to hear them in an art class seemed strange to me. In my economics class we did a project in which we ate as many Dunkin Donuts Munchkins that we could. The purpose of the project was to point out that the first donut gave us the most satisfaction, and as we ate more and more, the satisfaction decreased. One gets the most satisfaction or pleasure from the first time experiencing something. The same goes with art. The first time you experience something you gain the most pleasure from it. Also, the same theory can apply to the decreasing satisfaction one can get from experiencing art that was a copy of an original. The original would give more pleasure and the copy would give less.

Therefore, a question i pose is could one gain more satisfaction from a non original or copy of a work of art?
