Suppose the government decides to set the price of the good equal to marginal cost and subsidize the firm in order to get the firm to produce enough output to satisfy the market at that price

/in /by

home / study / business / economics / questions and answers / 1. (18 total points) suppose there are Show more home / study / business / economics / questions and answers / 1. (18 total points) suppose there are 8 firms Question 1. (18 total points) Suppose there are 8 firms located equidistantly around a circle whose circumference is equal to 1. There are 400 consumers distributed uniformly around the circle. Each consumer gets utility U = 3.5 from buying a unit of the good from a firm which sells their ideal brand (a firm located at the consumers location). Also the consumers utility decreases by 4 times the distance that the consumer is located from the firm. So a consumer who buys from firm i gets utility given by Ui = 3.5 4xi where xi is the distance from the consumers location to firm is location. The consumers surplus from purchasing a unit of the good from firm i is the difference between their utility from purchasing a unit of the good from firm i and the price that firm i charges. So CS = Ui Pi. Also the consumer has no alternatives so the consumer will buy a unit of the good if maximum surplus gained from purchasing from any firm is greater than 0. a) (6 points) Consider a particular firm denoted Firm 2. Let Firm 1 be the firm located on one side of Firm 2 and let Firm 3 be the firm located on the other side of Firm 2. Suppose Firm 1 charges a price P1 = 2 and Firm 3 charges a price P3 = 2. Write a general expression for Firm 2s demand. b) (4 points) Suppose Firm 2 can produce its good at constant marginal cost MC = 1.5. What price should firm 2 charge if it wants to maximize its profit? c) (4 points) Suppose the firm has no close neighbors so that it acts as a monopolist. Therefore it captures all of the consumers whose surplus is greater than or equal to 0. Write a general expression for the firms demand. d) (4 points) Suppose the monopoly firm can produce its good at constant marginal cost MC = 1.5. What price should it charge if it wants to maximize its profit? 2. (15 total points) Suppose that assuming a firm decides to produce a product it must build a production facility. The fixed cost of this facility is F = 90. Also the firm has constant marginal cost MC = 5. Demand for the product that the firm produces is given by P = 40-5Q. a) (8 points) On a single graph carefully draw the MC curve the demand curve and the ATC curve. Your graph should go up to 8 units of output. Please label your graph carefully. b) (3 points) How much output will this firm produce? Suppose the government decides to set the price of the good equal to marginal cost and subsidize the firm in order to get the firm to produce enough output to satisfy the market at that price. c) (2 points) How much should the subsidy be in order to allow the firm to make exactly zero profit. d) (2 points) How much consumer surplus will consumers get if P = MC? 3. (17 total points) Suppose there are two types of consumers: Type A and Type B. The demands for a monopolists product for each type of consumers are given by: Type A: Q = 90 2P Type B: Q = 60 4P Assume the marginal cost of production is constant and MC = 4 and there are no fixed costs. a) (5 points) Suppose the firm is unable to distinguish between the two types of consumers and therefore cannot engage in price discrimination. Sketch the demand curve facing the firm. Make sure your graph is accurate and carefully labeled. b) (2 points) What price will the monopolist charge? c) (2 points) How much profit will the monopolist make? d) (2 points) If the monopolist is able to charge different prices to each type of consumer what price will she charge to type A consumers? e) (2 points) What is the Price Elasticity of Demand for Type A consumers? f) (2 points) If the monopolist is able to charge different prices to each type of consumer what price will she charge to type B consumers? g) (2 points) What is the Price Elasticity of Demand for Type B consumers?

Econ-Admin 2250H – Suppose the advertising decisions of two firms are inter-related. Firm 1 always spends $2 million

Question

TRENT UNIVERSITY

DEPARTMENT OF ECONOMICS

Econ-Admin 2250H 2015-2016

Assignment #2

Date Given: Beginning of class on October 9, 2015.

Due Date: Beginning of class on November 6, 2015.

As page 3 of your course outline states: “the penalty for
late assignments is 20 percentage points

for each day or part thereof.” To be fair to all students,
the late penalty will be applied to all late

assignments, even if they are late by an hour. You have four
(4) weeks to complete this

assignment.

Notes: Please make sure that your answers are neat and
legible. Also ensure that your assignment is

securely held together and contains your name and student
number. The numbers in the margin

refer to the mark for each part. Please type your answers or
use a pen. Do not use a pencil.

(15) 1. Suppose the advertising decisions of two firms are
inter-related. Firm 1 always spends $2 million plus 33?% of

what firm 2 spends on advertising. And firm 2 always spends
$7 million plus 12.5% of what firm 1 spends on

advertising.

i) Draw the reaction functions for the firms in this problem
(in the same diagram). Be sure to

label each curve and the axes.

ii) Use the inverse matrix method to find the Nash
equilibrium in this problem.

iii) Now use Cramer’s rule to verify your answer in part
ii).

2. Suppose an inflationary economy can be described by the
following equations representing the goods and

money markets:

C = 20 + 0.7Yd

M = 0.4Yd

I = 70 – 0.1r

T = 0.1Y

G = 100

X = 20

Ld = 389 + 0.7Y – 0.6r

Ls = 145

where G represents
government expenditure, M is imports, X is exports, Y is national income, Yd is

disposable income, T
is government taxes (net of transfer payments), I is investment, r is the rate
of

interest, C is
consumption, Ld is money demand, and Ls is money supply.

(15) i) Use the inverse matrix method to solve for the
equilibrium level of national income and the

equilibrium rate of interest in this economy. (Note: ½ of
the marks in this part are given for

the correct set up of the equations. Explain what you are
doing, including how equilibrium

is established in each market.)

(5) ii) Now use Cramer’s rule to find your answer.

3. There are three types of life insurance policies that a
sales representative can sell: term, whole life,

and universal life. The following matrix gives the number of
policies sold by three different

representatives during a recent month:

representative A

Assume representatives A, B, and C earned $4400, $4060, and
$4160, respectively, in

commissions for these sales. The commission earned depends
only on the type of policy sold and

is the same for all representatives.

(10) i) Use the inverse matrix method to find the commission
that is earned for selling a policy of

each type.

(10) ii) Now use Cramer’s rule to find your answer.

(15) 4. You are the distributor for a certain brand of wine.
The manager of a local liquor store has just

called, wanting to know why this week’s order had not come
in. You try to explain that your route

driver called in sick this morning, but the manager demands
the usual order and wants its delivered

within the hour. Unfortunately, you do not know what the usual
order is and you cannot reach the

driver. A quick check of the account shows that during the
months of April, May, and June, this

customer was billed for $456, $474, and $499, respectively.
The following matrix gives the price

per case of each of your three kinds of wine during those
months. Using Cramer’s rule find how

many cases of each kind of wine constitute this store’s
usual order.

Determine the monthly interest rate for

each type of loan using both the inverse matrix method and
Cramer’s rule. Now calculate the

annual interest rates this company is charging. Show your
work for all the subparts of this question.

Do you think ideology should be used to reject federal court nominees or should approval be based solely on experience and qualifications?

/in /by

Ideology
During both the Bush and Obama administrations, opposition party members argued that the Supreme Court nominees ideological viewpoints were too extreme for the American ideological points of view. This argument will likely surface as President Obama has pledged to nominate Justice Scalia’s replacement to the Supreme Court. Do you think ideology should be used to reject federal court nominees or should approval be based solely on experience and qualifications? If you believe ideology should be used, what role does the electorate play in determining judicial appointees? If you do not believe ideology should be considered, what factors would determine the qualifications of a federal appointee?

All additional resources from each week
Review the following scenario:
Acting as the CEO of a small company, you will apply the
principles of capital budgeting to invest in growth and cash flow
improvement opportunities in three phases over 10 simulated years.
Each opportunity has a unique financial profile and you must
analyze the effects on working capital. Examples of opportunities
include taking on new customers, capitalizing on supplier
discounts, and reducing inventory.
You must understand how the income statement, balance sheet, and
statement of cash flows are interconnected and be able to analyze
forecasted financial information to consider possible effects of
each opportunity on the firm’s financial position. The company
operates on thin margins with a constrained cash position and
limited available credit. You must optimize use of internal and
external credit as you balance the desire for growth with the need
for maintaining liquidity.
Sign-in to the simulation and review each of the following:
•Welcome Statement •How to Play •Terminology Primer •More
Details (this includes information to help you understand how to
play the simulation)
Write a paper of no more than 1,400 words that analyzes your
decisions during each phase (1-3) and how they influenced each of
the following final outcomes (metrics) of SNC:
•Sales •EBIT •Net Income •Free Cash Flow •Total Firm Value
Address the following in your paper:
•A summary of your decisions and why you made them •How they
affected SNC’s working capital •What general effects are associated
with limited access to financing
Include scholarly references (in addition to your course
textbook and simulation materials) to support your positions.
Format your paper consistent with APA guidelines.
