    FALL 2013

    MIDTERM 2

    Read all instructions on this pageThis test is governed by UFs academic honesty code. It is intended to have 30

    multiple choice questions. Please check to be sure your copy has all 30. MAKE

    CERTAIN THAT YOU LOOK AT BOTH SIDES OF THE LAST PAGE!! Choose

    the best answer for each question.

    The next is important: Unless you are specifically told otherwise, on this test do

    notassume that demand or supply is either perfectly elastic or perfectly inelastic.

    On the bubble sheet, please enter:

    1. Your name and initials

    2. Your UF ID number3. Form code: A

    4. Sign your name on the bubble sheet.

    Check that the form code and UF ID number you bubbled-in are correct now. Also check

    to be sure your name is correctdo 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 FORM CODE AND UF ID NUMBER. IF YOU GET EITHER OF

    THESE WRONG, YOUR TEST MIGHT NOT BE GRADED AND IF IT IS GRADED,

    YOU WILL LOSE 3 POINTS!

    TURN OFF ALL CELL PHONES AND OTHERCOMMUNICATION DEVICES

    Youmay notuse a cell phone or any other sort of device that allows for communication

    as your calculator.

    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 allquestions

    during the test. I dont like this policy, but it seems the fairest policy.Do not ask questions of me or the TAs; in the interest of fairness I

    have instructed them not to answer any questions during the exam.You will have one hour (60 minutes) to complete the exam andbubble in all your

    answers. When the TAs say that time is up, you musthand 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 class web page after 10 PM.

    The test scores will be on class web page within a few days.Once you see the answer key, you might have a question about why one answer

    is right and another is wrong. For these questions, email me at

    mark.rush@warrington.ufl.edu Do NOT email the grader about these questions!

    After the scores are posted, if you think your posted score is incorrect, then email

    the grader at eco2023.grader@warrington.ufl.edu If you email me about your test

    score, I will not forward the email nor respond to youyouMUSTemail the

    grader. 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 reportswhat you

    bubbled in for each question and you ask the grader to check an answer because

    you believe you bubbled in something other than what is reported and the

    reported answer on the web is correct, you will lose 1 additional question.
