On the scantron bubble sheet, please enter: 1. Your name and initials 2. Your UF ID number 3. Special Code: 11 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 36 multiple choice questions. Please check to be sure your copy has all 36. If you do not answer a question, you will not get credit for that question. ♦ 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 may not use a cell phone, a Blackberry, or any other sort of device that allows for communication as your calculator. You will have 60 minutes to complete the exam and bubble in all your answers. This time includes completing the extra credit question if you choose to answer it. 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 if the test code and UF ID number you bubbled‐in are correct now. Also check to be sure your name is correct—do it now. I have heard a rumor that the ability to correctly record these had been mastered by a few students at FSU as well as a couple of accounting and journalism students. I will investigate these rumors but in the meanwhile, CHECK YOUR TEST CODE AND UF ID NUMBER. IF YOU GET EITHER OF THESE WRONG, YOU WILL LOSE 5 POINTS!!!! ECO 2023 MIDTERM 1 SPRING 2008 After the scores are posted, if you think your posted score is incorrect, email the grader at the email address on the syllabus page and the last question on this exam. 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. EXTRA CREDIT QUESTION INSTRUCTIONS There is an extra credit question on the last page. You can earn up to 3 points added to this exam’s test score. If you choose to answer the extra credit question, be sure to follow all the instructions on the page with the extra credit question and provide all the required information. DO IT LEGIBLY IF WE CANNOT READ YOUR NAME AND/OR UF ID, YOU WILL NOT GET ANY EXTRA CREDIT! When you hand in your test, you must hand in the extra credit page. You may copy your answer to the extra credit question in the space below. I will announce in class when the extra credit questions are graded and will post the grades on the class page but it will take a week or two. Do not email me, the grader, or the email address for questions about when the extra credit will graded. I will announce this in class. THERE IS NO APPEAL ABOUT THE GRADE—IT IS WHAT IT IS. 2 ECO 2023 MIDTERM 1 SPRING 2008 1) Vera Bradley makes a specific style of cloth purses.
