Problem Set 9 is now available (due in discussion sections during the week after Thankgiving). I will normally post problem sets each Saturday afternoon by 6 pm.
I strongly advise you to work through the problems before your next discussion section. It is okay to talk with your friends about the problems, but it is important that you understand them. Your problem sets will not be graded individually, but your TF will ask you to discuss the problems, and your general understanding during the semester will count towards your discussion-section grade. Here is the link: problem-set assignments.
1. Problem Set 9 will be posted on Saturday, November 18. There are no discussion sections on Thanksgiving week (Nov 20-24), but PS 9 will be discussed in your sections during the week after the Thanksgiving break (Nov 28 – Dec 1). Be ready.
2. Students are using six clickers with unknown Clicker IDs (the hexadecimal numbers on the back of your clicker under the barcode). The unknown IDs are:
68F6BA, 68F6FB, 68F991, 68F9CA, 691325, 7B4DEB.
Check the back of your clicker. If one of those clicker IDs is yours, please send me an email telling me which number is yours. Include your lecture (DD or EE) and your BU Student ID in the email. (Please do NOT send me an email if none of those numbers are yours.) Then register your clicker on BlackBoard again, and be sure to add your clicker ID.
Please remember that your clicker score does not affect your course grade unless your clicker data show that you have been absent for more than four lectures. In that case, I will send you an email after the last lecture and ask you to explain your absences.
3. If you completed the Doodle Survey to change the time of the exam, then go to the exam at the new time. You will NOT receive an official confirmation, so don’t worry about that.
The outline for Lecture 19, Thursday, 11/16/2017, is now available on the Lecture Outline Page.
All four versions of this exam, and the answers to the exam are available on the course website under Classes > Exams. The practice exam, with answers on the last page, is also available there. Your TF will return the question booklets to DD students and review exam questions during your discussion sections, Nov 8 to 10. If you have questions about the economics, attend your TF’s office hours, your instructor’s office hours, or email your own TF, not the course instructor.
To see how your midterm exam will affect your course grade, go to Course Information > Exams and Grades.
Individual Scores on Midterm 2 (Version, Number Correct, Adjusted Percentage Score) are now available on Blackboard under My Grades. The TFs and I considered this exam to be more difficult than normal, and for reason I adjusted everyone’s score upwards by 2.5 percentage points (the equivalent of one additional correct question). However, I was surprised to see that the average performance on this exam before the adjustment was almost identical to the average on Midterm 1.
If your performance turns has been poor because you haven’t understood much of the material, you may want to drop the course this semester, and take it again in a future semester or in the summer. This coming Friday, November 10, is the last day you can drop the course with a ‘W’ placed on your transcript. I understand that you can drop the course using student link, though I would be happy to discuss this with you during my office hours this Friday, 10-12.
The Midterm 2 Practice Exam is now available. The real Midterm 2 exam that you will take in lecture on Tuesday, November 7, 2017, is very similar to the practice exam, and the instructions are the same. BE SURE TO READ THE INSTRUCTIONS NOW!
I suggest that you print out the practice-exam question booklet, allow yourself 1 hour, and take the exam. The correct answers are posted separately. For the practice exam, circle your answers in the booklet that you printed. After you have taken the practice exam, compare your answers with the posted answers (available at the end of this week). If your own answer is different from the posted answer, think about why the posted answer may be better than your own answer, discuss the question with other students, and if necessary consult with TFs in the Principles Center , which is open between 10 am and 6 pm every weekday. Of course, it is always possible that a posted answer is incorrect :-( .
I have asked the TFs to review Problem Set 7 in this week’s discussion sections and not to spend time reviewing the practice exam. However, a few of the TFs may decide to discuss a small number of practice-exam questions that the class found to be especially difficult or confusing.
The lectures this week (on Tuesday, 10/31, and Thursday, 11/2) will cover Income/Substitution Effects, Producer Cost, Profit Maximization and Long-Run Competition, so you may want to postpone answering practice-exam questions on those topics (marked with *) until after I have given the corresponding lectures.
The practice exam and Midterm 2 are intended to cover Lectures 9 to 16 as listed on the Course Schedule. To view and print the practice exam questions go to the Exams page. Go to the Scantron Example to see how to enter your answers during real midterm.
If you are a EC101 DD student who is also enrolled in QST SM131, you will be permitted to take the EC101 final exam with the EC101 EE students on Saturday, Dec 16 at 3:00 – 5:00 pm in the LAW Auditorium. If you do not want to take the EE exam, then you have the right to take the EC101 final exam at the original time on Dec 19 and take the SM131 exam at another time. The SM131 instructors have agreed to this policy.
If you want to change your final exam to Saturday, Dec 16 at 3:00-5:00pm, please enter your BU Email Address and the number of the course that conflicts in the Doodle Poll at the following link:
Entry example: firstname.lastname@example.org, SM131
If you ask to change, you then will be required to take the exam on Saturday, Dec 16 at 3:00 – 5:00 pm in the LAW Auditorium.
Teaching-fellow office hours have been posted since the first week of classes are available Monday to Friday, 10:00a to 6:00p. I urge you to take advantage of them. Go to Classes > Office Hours to see the complete schedule.
These are questions frequently asked by students in EC101 DD/EE. When students send me emails with questions about the course, I will update this post. –Michael
- Do I have to buy a clicker?
Yes. You are required to buy a Turning Technologies student-response device, often called a clicker. I recommend that you buy it at the BU Bookstore. The clicker comes with a 1-semester, 1-year or 5-year subscription–be careful not to lose the certificate. Go to Course Information > How to Buy a Student Response Device for more information. Be prepared for many steps :-( . I no longer allow students to use smartphone apps, because they often fail to connect to the internet during the lectures.
- I am unable to register or obtain a subscription (license) for my clicker. What should I do?
Call TurningTechnologies at 866-746-3015, 8:00am–9:00pm Boston time or go to their technical-support website.
- Where are the problem-set assignments?
All problem-set assignments will be posted on the course website. Go to Classes > Problem-Set Assignments on Friday evening of the week before they are due. The problems will be reviewed in your discussion sections on the week they are due.
- Do I have to finish assigned textbook readings in the Course Schedule by the date that’s given there?
No, the dates on the course schedule are only a suggestions. But try not to fall behind. Keep in mind that the exams (80 percent of the course grade) are focused on the lectures, and the textbook is to be used mainly as a reference and for the homework assignments and quizzes.
- Can I get a copy of the lecture slides?
No, I don’t distribute those. But you can download a pdf copy of the Lecture Outlines, which are similar to the slides. The outlines omit the pictures and some of the lecture details, but they leave you a place to add your own notes. To download the lecture outlines go to Classes > Lecture Outlines.
You can review the contents of a quiz, but only after the day and time the quiz is due. To review the questions, log into MyEconLab, and then click on Results in the menu on the left (do NOT click on Assignments). After that, you will see the word Review for each quiz in the list of quizzes. Click on Review.
