- Here is a partial solution guide to midterm #2
- Update: A helpful student pointed out an error in the
solution guide for HW #12.
- Here is the corrected answer guide..
- The error was on problem #1 (d). I mistakenly used 0.73 as pT,
the probability that a voter would be correct given that Friedkrug was
correct, and then 0.27 as 1-pT. In fact, we'd found in part (a) that pT
should be 0.88, and so 1-pT should be 0.12.
- The final computation shown in the answer guide is correct, it
must have been based off the correct calculations in spite of what was
shown. So, the overall probability of a majority vote being correct is
still approximately 0.768.
- I apologize for the confusion.

| May 2 |
- I will be having extra office hours Thursday (12pm-2pm).
- I intend to post a solution guide for midterm #2, but technical
glitches are preventing it, so it will probably not be able to happen
until Thursday morning.

- More will be coming here in the afternoon, check back.
- Wikibooks reviews and grading:
- If you did not specifically request a review, then I will be
giving you a grade on your Wikibook contribution on Wednesday.
- I am working on reviews of Wikibook pages you've been working on.
If you intend to keep working on the Wikibook, you should look at (at
least) two things, and read them carefully:
- First, look at these
overall review thoughts. They apply accross the board.
- Second, look at the specific review(s) for the page(s) you
intend to keep working on. Not all of these are done yet, but when they
are done they will be titled "TDang review April 2012". For instance: this
one for Expectations management.
- As I mention in the top of the reviews, the tone of my reviews
may come off as negative. Please don't let it be discouraging, however.
The emphasis on things I see which need improvement is the most direct way
I think I can help you improve the book.
- It is likely you and others will be editing the same material at
the same time, possibly responding to the same piece of a review. Make
small edits, and keep an eye out for changes made by others so you don't
step on each other too much, or get redundant.
- If you are concerned about the quantity of your contribution,
here is a spreadsheet which
might help. It can give you at best a very rough estimate, so don't
put too much weight on it, but if it looks like you've only done 20% of
the additions suggested, that might be something worth thinking about.
Update 2:This spreadsheet didn't do what it was supposed to on the
classroom computer, but does when I download it to my computer. So, you
should fee lfree to try it, it might work or not. You also probably have
some idea of how much editing you're doing without it.
- Update 1:Most of you will not be getting individualized
reviews from me. I will send you an individualized email only if I notice
a specific, significant problem with what you have done so far. If you
don't get an email from me, it is either because:
- You have done very little and so there's nothing worth
reviewing for you. This is obviously a significant problem, but one you
should be aware of without an email.
- Everything which needs to be said about your editing can be
said in the general review of the pages, rather than aimed at you
personally. This will be why for most of you.
- Here are Phil Hihn's lecture
notes from today.
- Here is an answer guide for
homework #12.
- Another note on writing for the Wikibook: The strict volume of your
editing is just a rough guide to the significance of your contribution. If
you do formatting improvements, this might not look like any change in the
size of a page, but it is helpful and will be considered. Fixing grammer
is the same. Adding graphics adds only a small amount to the size of the
page, but is significant both in helpfulness to the book and in work
required to do it, so will be considered a significant contribution.
(These are just examples.)

- Here are Dr. Dang's lecture
notes from today.
- Here are Phil Hihn's lecture
notes from today.
- For Monday, April 30, complete this
homework and hand it in, at the beginning of class.
- For Monday, please watch the following two videos:
- Two corrections/clarifications about grading:
- When I gave you your current participation score, I had it as "x
out of 15" points. In fact, according to the syllabus, it should be out of
12 points. When I give you your grade status next week, the points for
participation will be correct. I apologize for getting the scale wrong.
- If you are asking for a review rather than a grade on your
Wikibook contribution, then you will have up until the time of the final
exam to make more changes to your contribution which will be considered in
your grade. That means you will be graded on your editing as of 10:30am,
Friday May 4.

- It might be too late, but it's possible that you can get help with
the technology of Wikibooks editing from Taylor Corcoran during her office
hours on Tuesday.
- Taylor's office hours Tuesday are 1pm-3pm in the economics
department study room 401B.
- Taylor has edited Wikibooks before, so may be able to help you if
you're lost.
- However, Taylor's office hours are primarily devoted to
helping Econ 361 students, and those students have an exam this coming
Thursday. I have told Taylor that the Econ 361 students get priority over
the Econ 452 students, so ... she may be able to help you, or she may be
too busy.

| April 11 |
- Here are Dr. Dang's lecture notes from today.
- For Wednesday, April 18, complete this homework and hand it in, at the beginning of class.
|
| April 9 |
- What's coming up:
- Infotopia: We'll be reading Infotopia, supplemented by some other readings and some more formal
modeling of the ideas in the book. For next lecture, please read the Introduction and Chapter 1. The book is a fairly easy
read, so you might want to try to read the whole thing as soon as you're able.
- Wikibook: You need to be preparing to finish up your Wikibook editing. Here's what I want from you:
- According to the syllabus, Wednesday, April 25 is the last day for Wikibook contributions. I'm going to add just
a little bit of flexibility to that.
- By Wednesday, April 25, I want the equivalent of 3 good pages that you have done on the book. That means
good information and/or analysis, with references, well-formatted and proof-read.
- Once you have that, you have two choices. You can ask me to review what you have done, or to grade
what you have done.
- If you ask me to grade what you have done, then I will consider that your completed work for the course,
and will ignore any editing after that point in deciding your grade. The possible advantage to you of doing it this way is
that you will be able to get a more complete grade status from me before the final exam. However, if you don't think your
grade is satisfactory, it will be too late to change it.
- If you ask me to review what you have done, then I will not give you a grade until after the final exam,
but I will look over what you have done and give you some feedback, likely including suggestions for improvement. The
advantage to you of doing it this way is that you will have a little more time, and will have a chance to act on the
feedback I give you, and hopefully wind up with something better.
- I will expect most of your work to be what we decided (you chose, or I assigned) in the "editing plan" section
of the classlist. If you need to do something different (or you never choose an area to work) you should contact me about
that.
- You can estimate how much you have added by using a "DIFF" to compare different versions
of the page you are working on. (For instance, here is a DIFF of some changes I made to one of the
pages.)
- You can estimate how many pages the Wikibook page would be if printed by going to "Print/export" on the bottom
of the left-hand-side menu, and choosing "Download as PDF" to see how it would print.
- You should feel free to ask me for advice on how to proceed, but time is short and I might not be able to
respond immediately.

- Here are Dr. Dang's lecture
notes from today.
- The notes from today are sparse because a great deal of the class
was taken up by the experiments. We'll continue to talk about them, so as
a reminder, here are the rules for (Experiment
#1), (Experiment #2).
- There are also some comments relevant to the experiments
on the wikibook.
- Here are Phil Hihn's lecture
notes from today.
- For Wednesday, April 3, complete this
homework and hand it in, at the beginning of class.

- Here are Phil Hihn's lecture
notes from today.
- Don't forget the homework and reading assignments for Monday, March
19 (see below).
- Here are two potential sources to use in working on the Wikibook:
- First, if something has the proper licenses, it should be possible
to import it to Wikibooks. For instance, it is legal to import material
from Wikipedia to Wikibooks. If you would like to do this, there is a
particular way to go about it, so comunicate with me about it first.
- Second, I have begun uploading versions of my lecture notes to
Wikibooks, not as part of the Wikibook but so that it is legal to copy
stuff from there to the Wikibook proper.
- The material is linked from this
page as "rough lecture notes".
- You may use this material without checking with me first.
However, for the sake of academic integrity, mention (probably in the edit
summary) when you do so.
- This does not mean you can use the material that is in my
lecture notes posted on the course web page. You may use those notes for
inspiration and ideas, certainly, but not to copy material from.

- Please go look at the
notes on editing plans I have commented on what you wrote, possibly
giving you some suggestions, or maybe telling you you need to change to
something else. If you asked me to assign you a topic, I did so there.
- If you don't see a comment from me, or an editing plan for yourself,
then you haven't either selected a plan or asked me to assign you one. You
should do so. See the assignment below on February 8.
- We're going to shift gears to talking about network externalities
now. That material is not in your textbook, and so we'll be relying
largely on lectures. However, you should also read in the Wikibook:

- Before lecture on Mnday, for the wikibook project:
- Go to the
"editing plan" area and, under your username, indicate what you plan
to start working on (see the instructions there for some thoughts).
- If you can't choose, that's OK, but then please email me and let
me know. I will assign you something to work on.

- Next week, we'll be getting into durable goods. Please start reading
the chapter on "Decision Making Over Time: Durability".
- Homework #3, question #3 is asking you something about two-part
tariffs which you might not be ready for (based on where I've gotten in
lecture). You should skip question #3. If you've already worked on
it, don't worry, it should come back up again. (Questions #1 and #2 will
be re-weighted to account for #3 being missing.)

| January 30 |
- Here are Dr. Dang's lecture
notes from today.
- Here are Phil Hihn's lecture
notes from today.
- Please read the chapter on "Advanced Topics in Pricing" (more
material on price discrimination) for next Monday.
- If you haven't already, read the online articles linked below for
Wednesday.
- For Monday, February 5, please do a brief review of one page of the
wikibook:
- I've given you some more instructions, and assigned which page I'd
like you to review on your personal Wikibook "talk page". Make sure it's
there. If it's not there, something may be wrong and please email me right
away.
- I'd really like this done before class on Monday, but in case you
have difficulty with the Wikibook-editing part, it won't be considered
late as long as it's done sometime on Monday. That gives you the option of
asking Taylor Corcoran (or possibly me) for Wikibook assistance.
- You are likely to be in over your head on this. That's deliberate,
and don't let it worry you. Some of the pages will be material which
seemed appropriate when first added to the book, but maybe isn't. Some of
the pages will be on material we won't cover until later in the course.
And some will just be confusing until they are better-edited. Read what's
there, and make suggestions.

| January 25 |
- Here are Dr. Dang's (very cursory today) lecture
notes from today.
- Here are some extra notes to fix an error. (On reviewing the lecture, I
realized I had been misleading on monopoly pricing and elasticity. These notes should correct that, and the correction
will also be discussed on Monday.)
- Here are Phil Hihn's lecture
notes from today.
- Please read the chapter on Price Discrimination for Monday, January
30.
- For Wednesday, February 1, complete this
homework and hand it in, at the beginning of class.
- Also for Wednesday (or even better for Monday), please read the
following two web articles to discuss in class:
|
| January 23 |
- There was a problem with the homework. On problem number 2,
the demand function was defined incorrectly. This will make the problem
pretty nonsensical, and hard to solve. This
version has been corrected.
- Here are Dr. Dang's lecture
notes from today.
- Here are Phil Hihn's lecture
notes from today.
- If you find yourself needing help with Wikibook editing, besides
myself, you can visit the preceptor Taylor Corcoran at office hours.
Taylor won't be able to help you with 452 course material, but has edited
a Wikibook before.
- Monday 11am-1pm (401A)
- Tuesday 1pm-3pm (401B).

- Here are Dr. Dang's lecture
notes from today.
- Here are Phil Hihn's lecture
notes from today.
- By class time Monday, Juanuary 23, make one minor
improvement:
- This could be a spelling correction, a re-phrasing, cleaning up
formatting. It doesn't need to be anything major, just a little
improvement to get you started editing.
- By "On the Wikibook", I mean anything that is part of this book:
Strategy
for Information Markets
- Be sure you are logged in when you do the edit.
- For Wednesday, January 25, complete this
homework and hand it in.
