Why that is a trapezium?
Some interesting thing left un-noted in the previous post, I better put it down when I still have a fresh memory now.
After I finished my illustration, and returned to my seat, the girl (with short jeans skirt) sit next to me, ask me a question about what I have just explained in board. Obviously, she did not want to ask me when I am still in front of the class. (So she prefers to do it privately instead of publicly. Is that implies something?) As you can refer to the post yesterday, I did monopoly model. To draw MR cut MC is easy, so the prof asked me to indicate the consumer surplus, producer surplus and deadweight loss. I have chosen a monotonically upward slopping MC curve, hope you know how the diagram looks like, if not, please refer to the textbook.
The question from her is, "why PS is a trapezium?"
Indeed I did explain that in my diagram, I have cut the DWL into half, and stated clearly the lower part belongs to Producer if there is perfect competition. The immediate thing I did, was not pointing back to the diagram I drew, instead I took up a pencil, and draw her a new graph with U shape MC. Can you guess what she asked then?
At this point, it should be clear that nothing implied, excerpt she is smart. If she really asked me that when I still stand next to the board and with a chalk in hand, do you know what will I do?
