Freakonomics
One of the few books about economics to recently hit the New
York Times bestseller’s list was Freakonomics by Levitt and Dubner. The book was so popular they even made a
movie about it. The specialty of Levitt
and Dubner is applying economics to unconventional, controversial, or sometimes
even downright bizarre topics. Some
praise them for bringing economics to a wider audience, while others criticize
them for not tackling serious issues or for delving into overly conversional
areas.
So what’s all the fuss about? Take a look for yourself by viewing some of
their videos from YouTube, including clips from their movie, or take a look at
some articles at their blog. The links
are below:
https://www.youtube.com/user/FreakonomicsVideos/playlists
http://freakonomics.com/category/freakonomics-blog/
Choose one of the videos or blog articles that you find most
interesting, and share the link with your classmates. Discuss some of the following issues based on
what you have viewed or read:
What did you find interesting about the video or article
that you found?
Did you find anything from any of the videos or articles
that might help you understand some concepts from the class, or is their stuff
too odd or far out there to be useful for this class?
Overall, what is your impression of Levitt and Dubner? Silly?
Interesting? Bizarre? Informative? Boring? Other?

Interactive Tools for Production and Costs
For this discussion, we will be looking at several
interactive tutorials or quizzes that might help you and your classmates with
any concepts or calculations that you are having difficulty with.
If you are having difficulty with the numerical calculations
covered in this module, try this interactive tutorial:
http://www.sambaker.com/econ/cost/cost.html
If you are having difficulty with some of the conceptual
issues covered in this module, try the following interactive tutorial:
http://www.pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=12353
Note that you don’t need to look at both tutorials, just
pick one or the other and share with your classmates whether you found it useful
or not.
Then search the web and try to find at least one other
tutorial on production costs (marginal costs, variable costs, total costs,
etc.) that you find useful for this module. This could be a tutorial, a video
lesson, an online practice quiz, etc.
Share the link with your classmates and explain what you found useful
about it. As a follow-up to your first
post, try using one of the tutorials that your classmates found and share your
thoughts.

Oligopoly and Game Theory
ou may have noticed the discussion in Taylor (2014) at the
end of Chapter 10 about oligopoly and the prisoner’s dilemma. The prisoner’s dilemma is an example of game
theory. A “game” is like a board game,
as your optimal move depends on what your opponent does. The same holds in oligopoly, as your own
decisions as to what price to charge or how much to produce depend on what your
competitors do.
Take a look at the following video that tries to illustrate
oligopoly and game theory through a Batman movie:
https://www.youtube.com/watch?v=JMq059SAQXM
Find one other YouTube video on game theory and share the
link with your classmates. Then discuss
the following issues:
Did the Batman video or the other video you found help
explain the concept of game theory? Or
was it just silly?
Besides oligopoly, can you think of any other situations
that game theory is useful for? This can be situations in the business world,
in your own workplace, or even something you saw in a movie or TV show.
What do you find easier to follow – the game theory matrices
or the math equations/computations that you’ve used in this class?
Finally, watch some of the game theory videos that your
classmates found and give your comments on these videos.

Mergers
One of the hottest topics in the business press are rumors
of major corporations merging together. Just as the entertainment press likes
to report on rumors of celebrities who are dating, the business press likes to speculate
about “corporate match-making”. For example, Whole Foods was subject to rumors
about several potential suitors including supermarket giants such as Kroger,
Albertson’s, and Walmart. But the world was somewhat surprised when a merger
deal with Amazon was announced, as this seems like a bit of an “odd couple”.
Go to Google news or other news search engines and see what
the latest merger rumors are. Pick one of the merger rumors that seems the most
unusual to you – one that makes you wonder why these two companies think they
are a good match for each other. Share the link to the article with your
classmates, and discuss the following issues:
Is this merger horizontal? Vertical? Conglomerate (unrelated
diversification)?
Why do you think these companies would or would not make a
good match?
Do you think this merger will actually go through? Or won’t
get beyond the gossip stage?

SUPPLY AND DEMAND
Assignment Overview
Before beginning this assignment, make sure you have gone
carefully through all of the required readings for this module. It is very important to carefully absorb the
general concepts as well as the numerical examples in the background readings. For this assignment, you will have to answer
some purely conceptual questions, as well as some numerical problems. For conceptual questions, make sure to
thoroughly explain your answers and to cite specific readings from the required
background materials to explain your answers.
For numerical problems, make sure to show all of your work and explain
how you arrived at your answers (partial credit can be given if you get the
final answer wrong but do some of the steps correctly).
Case Assignment
Part A: Conceptual questions
Suppose you own a pet shop.
Your sales are decent but a marketing consultant tells you that you
could increase your sales and be able to charge a higher price if you spend
some money on local television ads. If
the consultant is right, will advertising lead to an increase in quantity
demanded? Or a shift in the demand
curve? Both? Neither?
Explain your answer and make sure to cite at least one of the required
readings in your answer.
You are the owner of a furniture factory. You normally produce 100 pieces of furniture
a day because that is how much you can produce given the amount of qualified
workers in your town and the amount of reasonably priced wood that you can
purchase locally. Then one day you get
an order from a large national retail chain who wants to purchase 200 pieces of
furniture a day from you. You are
hesitant, as you will have to pay higher wages to get some qualified workers to
move to your town. You also will need to
pay higher prices for wood because you will no longer be able to rely solely on
local suppliers and will have to spend more on shipping wood from other
towns. But you drive a hard bargain and
the retail chain agrees to pay one and a half times your normal price. Does this situation describe a change in
quantity supplied? A shift in the supply
curve? Both? Neither? Explain your answer and make sure to
cite at least one of the required readings in your answer.
Suppose marijuana has just been legalized in your
state. Nobody in your home town wants to
start a marijuana business, as this would be too much of a stigma. But being an MBA student, you know a good
business opportunity when you see one and decide to take a stab. Shortly after starting up your business, you
gain a loyal following of customers and start raking in some steep
profits. However, the local government
decides that they want a cut of your profits and starts charging a 20% sales
tax on marijuana. Do you think this
would lead to a 20% or greater loss in sales?
Do you think marijuana in this situation would be facing inelastic or
elastic demand? Explain your reasoning,
and make sure to cite at least one of the required readings regarding
elasticity.
Part B Quantitative Problem
Suppose the demand function for a new smartphone can be
expressed as QD = 1000 – 1.5P with QD
being quantity demanded and P being price.
The supply function can be expressed as QS = 50 + 2P
Fill out the following table using the above equations:
Price

Quantity Demanded
|
Quantity Supplied
|
Surplus Amount or Shortage Amount

Now answer the following questions:
What is the equilibrium price? You can compute this either using Microsoft
Excel, or by using algebra from the equations above and solving for a price
where quantity supplied equals quantity demanded. Show your work by either
showing the algebra steps or by showing how you used Excel to calculate.
Suppose the supply function changes to 100 + 2P. What is the new equilibrium? Show your work
by either showing the algebra steps or by showing how you used Excel to
calculate.

Module 1 SLP
SUPPLY AND DEMAND
For the SLP this session, come up with an idea for a
business you would like to start someday.
This should be a business in an industry that you are familiar with and
can find a lot of information about.
This could be a type of business that you are currently working for or
have worked for in the past, or a type of business that you are a frequent
customer of. Finally – since you will
have to make estimates about costs of starting up the business or what type of
price you can charge, it is best to keep your business idea relatively simple.
For this first SLP, discuss your business idea and do some
initial research on what prices your potential competitors in your home town
are charging. More specifically, write a
three-page paper discussing the following issues:
What business do you want to start, and why? Explain your
personal connection to this type of business and discuss sources of information
about this business that you plan to use for your SLP.
What prices are these businesses in your chosen industry
charging? Try to get at least ten
examples of businesses and the prices they are charging, and create a table
that lists the prices and any other relevant information, such as whether the
product they sell is high-end quality or lower-end quality.
Do you notice a large range of prices that businesses are
charging for the service or product? If
so, what factors do you think explain the range of prices? Is it the quality of the product or service,
location of the business, amount of advertising done by each business, other?
Based on your answers to Questions 1 and 2 above, do you
think your product or service will have elastic or inelastic demand? You don’t have to do any calculations since
you probably won’t have access to sales data on the businesses you are looking
at – but based on the range of prices, you should be able to get an idea about
how sensitive consumers of your product or service will be to changes in
price. In addition to your own research
about prices in your home town, cite some of the required background reading on
elasticity to justify your answer.

Before beginning this assignment, make sure you have gone
carefully through all of the required readings for this module. It is very important to carefully absorb both
the general concepts as well as the numerical examples in the background
readings. For this assignment, you will
have to answer some purely conceptual questions as well as some numerical

Note that you need to use Microsoft Excel to do the graphs for the numerical
problems.
Case Assignment
Part A: Conceptual questions
Suppose you own a television factory and at your current
level of output you have average total cost of $800 per television, average
variable costs of $700 per television, and a marginal cost of $400. If the price your buyers are willing to pay
is $500, should you decrease or increase production? Explain your reasoning, and make sure to cite
at least one of the required readings in your answer.
You are the owner of a restaurant, and currently you have
only one waiter. While this keeps costs
down, many of your customers go home because they are tired of waiting in line
or waiting for their order. You hire
four more waiters and waitresses, and you are now able to serve a dramatically
higher number of customers. Seeing the
huge productivity gains from hiring more staff, you then hire 20 more waiters
and waitresses. However, you are not
able to serve any more customers than you were able to when your staff size was
only four. In fact, your restaurant has
become overly crowded because there is not enough room in your restaurant for
all of your staff. You are confused as
to why hiring four more staff members increased your productivity, but hiring
20 more did not. What concept from the
background readings best describes what happened in this case? Explain your reasoning.

MARKET STRUCTURE AND GAME THEORY
Assignment Overview
As always, make sure to thoroughly review the required
background materials before starting the assignments. The assignment questions will require you to
do some calculations and also apply the concepts from the module. Question 3
differs from previous assignments in that you have to use an online simulation
tool; but this activity should be a fun break from the standard numerical
problems you have been doing.
Case Assignment
For this problem use the Herfindahl Index to compute market
concentration:
Suppose Apple has 45% of the U.S. market share for
smartphones, followed by Samsung with 30%, LG with 9%, Motorola with 8%, HTC
with 6%, and Nokia with 2%. What is the
Herfindahl Index for the smartphone industry based on these numbers? Based on
the Herfindahl Index, do you think the government would be willing to approve a
merger between Apple and Samsung?
Now suppose Nokia and Motorola come out with a new
smartphone that takes away a huge chunk of market share from Apple and Samsung.
The new market shares are 25% for Apple, 20% for Samsung, 20% for Motorola, 20%
for Nokia, 10% for LG, and 5% for HTC.
Use what you learned about perfect competition, monopoly,
and oligopoly to answer these questions:
In the table below is the quantity produced, the price, the
fixed costs, and variable costs for a perfectly competitive firm that faces a
constant price of $150 for its product regardless of the quantity it
sells. Use the information in the first
four columns to calculate the number for the last four columns. At what quantity should they produce based on
what you find with your results?
How do you think your answer might change if it became a
monopolist with all of its competitors leaving the market? Or if it became an oligopoly with only one or
two competitors?

You’ve read about the prisoner’s dilemma in the background
readings. Suppose you are a business
owner with just one main competitor. If
neither you nor your competitor cut your prices, you will both be more
profitable. However, if your competitor
lowers its prices and you keep your prices high, then you will lose all of your
sales to your competitor. Every month
you and your competitor place advertisements in the local newspaper with your
price – so you need to decide each month whether or not to keep prices high, or
lower them based on what you think your competitor might do.
Go to the following webpage and test out some of your
potential price strategies:
http://www.gametheory.net/Mike/applets/PDilemma/Pdilemma.html
The strategy “defect” indicates lowering your prices. The
strategy “cooperate” means keep prices the same. Try out different strategies,
such as cooperating all the time or defecting sometimes. There are five different rounds of this game,
each with a competitor with different personalities and different
strategies. Play all five rounds and
experiment with different strategic approaches.
Report your scores for each round, and discuss which strategies seemed
to work the best for you.

For this assignment, you will be building upon your Module 2
SLP by continuing to examine other businesses in your chosen industry. Remember
that the other businesses you wrote about in your Module 2 SLP will be your
future competitors if you decide to open your own business. So it is important to get an idea of the

following issues:
What market structure is there for this line of business in
your home town? Is this a monopoly, oligopoly, monopolistic competition, or
perfect competition? Justify your answer
using both your own research on this type of business in your home town, and by
referencing some of the required background readings on different types of
market structures.
Now that you have examined market structure of your chosen
industry in your home town, do some research on IBIS World on market structure
in this industry nationwide. You can
access IBIS World by going to the main TLC Portal and clicking on “Additional
