Unformatted text preview: Professor: M. Rush ECO 2023 SUMMER A 2007 MIDTERM 2 Read all instructions on this page On the bubble sheet, please enter: 1. Your name and initials 2. Your UF ID number 3. Special Code: 21 4. Test code: A 5. Sign your name on the back of the bubble sheet. This test is governed by UF’s academic honesty code. It is intended to have 35 multiple choice questions. Please check to be sure your copy has all 35. ♦ The next is important: Unless you are specifically told otherwise, on this test do not assume that demand or supply is either perfectly elastic or perfectly inelastic. Do not ask questions of me or the TA’s; in the interest of fairness I have instructed them not to answer any questions during the exam. I have become increasingly concerned that some students are at a real disadvantage because they are unwilling to ask questions during the exam while others ask a lot of questions. Hence, to level the playing field, I have decided to eliminate all questions during the test. I don’t like this policy, but it seems the fairest policy. TURN OFF ALL CELL PHONES AND OTHER COMMUNICATION DEVICES You will have one hour (60 minutes) to complete the exam and bubble in all your answers. When the TAs say that time is up, you must hand in your exam. We will not give extra time to finish bubbling in the answers, so be sure you are done when the 60 minutes are up. Of course, you may hand in your test at any time before the 60 minutes are up. An answer key will be posted on the Web later this evening. The test scores will be on the Web within a few days. Check that the test code, special code, and UF ID number you bubbled‐in are correct now. Also check to be sure your name is correct—do it now. As I said on the last exam, I heard rumors that the ability to correctly record the test code has been mastered by a few students at FSU. I am still checking this out. But in the meanwhile a friend told me that accounting majors have been known to be able to record this letter, often correctly. Plus, I have heard of one journalism major who could get the special code right at least 30% of the time! While I doubt this last rumor, because the special code involves numbers which means it is close to being math, nonetheless I think that the skill of correctly bubbling in the test code and special is not too difficult to acquire. CHECK YOUR TEST CODE AND UF ID NUMBER. IF YOU GET EITHER OF THESE WRONG, YOUR TEST MIGHT NOT BE GRADED OR YOU WILL LOSE 5 POINTS! ECO 2023 MIDTERM 2 SUMMER A 2007 After the scores are posted, if you think your posted score is incorrect, email the grader at ECO2023.grader@cba.ufl.edu. You have one week after the curved score is posted to request a grade check. After a week, the score will not be changed. If the web reports what you bubbled in for each question and you ask the grader to check an answer because you believe you bubbled in something other that what is reported and the reported answer on the web is correct, you will lose 1 additional question. 2 ECO 2023 MIDTERM 2 SUMMER A 2007 1) There are many cell phone manufacturers, each producing somewhat different cell phones.
