Bertrand Equilibrium. The ready-to-eat cereal industry is a classic oligopoly. General Mills and Kelloggs each have about 35% of the market, with private labels dominating the rest. Breakfast cereals are also highly differentiated, whether through ingredients, advertising or product form (flakes, nuggets, etc.). Therefore, suppose for the purposes of this question that General Mills (G) and Kelloggs (K) compete as Bertrand oligopolists by setting prices for their cereals. Assume also that production costs are zero so the objective of each firm is to maximize their total revenue, given their expectations of what the other firm will do. The demand facing each firm is given by: qi =12-2p i +p j
where i, j = K, G. If G and K compete as differentiated-product oligopolists, then find the Bertrand-Nash equilibrium price each will set and calculate the implied profit.

Answer 1

The Bertrand-Nash equilibrium price each will set is 6, and the implied profit is 6q.

How to determine Bertrand-Nash equilibrium

In the Bertrand oligopoly model, each firm's objective is to maximize revenue, given their expectations of what the other firm will do. Firms compete by setting prices for their products.

Bertrand-Nash equilibrium is a situation in which each firm is charging the price which is equal to its marginal cost. In this situation, no firm can gain any profit by deviating from the present strategy.

The given demand function for General Mills and Kellogg is as follows:

qi=12−2pi+pj

where i, j=K, G.

To find the Bertrand-Nash equilibrium price, we need to compute the reaction function of each firm.

The reaction function tells us what price a firm will charge, given the price charged by the other firm. It is the best response of a firm to the price set by its competitor.

For General Mills (G), we have:

qG=12−2pG+pK ⇒ pG=6−12qG+12q

KqG=qK ⇒ pG=6−12qG+12qG ⇒ pG=6

For Kellogg (K), we have:

qK=12−2pK+pG ⇒ pK=6−12qK+12q

GqK=qG ⇒ pK=6−12qK+12qK ⇒ pK=6

Therefore, the Bertrand-Nash equilibrium price is pG = pK = 6.

The profit of each firm is calculated using the following formula:

πi=qi(pi−c)

For General Mills:πG=qG(pG−0)=qG(6−0)=qG*6

For Kellogg:πK=qK(pK−0)=qK(6−0)=qK*6

As the production cost is zero, the profit of each firm is proportional to the quantity sold.

Substituting qG = qK in the above expression, we get the following equation for the total profit:

Total profit = 6q

where q is the quantity sold by each firm at the equilibrium price of 6.

Therefore, the Bertrand-Nash equilibrium price each will set is 6, and the implied profit is 6q.

Ivan Allen, former mayor of Atlanta, was best known for bringing a significant economic growth and providing pivotal leadership during the turbulent years of the Civil Rights Movement.

What should we know about Ivan Allen?

Allen, convinced that the South could never thrive economically under segregation, supported African Americans' demands for access to public facilities. On his first day in office, he directed the removal of all "white" and "colored" signs from city hall facilities.

Allen's racial alliances with Martin Luther King Jr. and others in the African American community, combined with his advocacy for public accommodation of African Americans in the white community, enabled him to guide Atlanta through the turbulence of racial integration without the violence that occurred in many southern cities. In a major public address, he urged Atlantans to end racial segregation and set an example for "all the world" to follow.

Answers

The opportunity cost of agriculture and industry in the USA and Germany can be calculated by subtracting the productivity of each sector from the total productivity of the other sector.

For the USA, the opportunity cost of agriculture is: 2,225,069 - 110,267 = 2,114,802. The opportunity cost of industry is 9,603,977 - 2,225,069 = 7,378,908.

For Germany, the opportunity cost of agriculture is 2,161,361 - 55,871 = 2,105,490. The opportunity cost of industry is 5,027,138 - 2,161,361 = 2,865,777.

Therefore, the opportunity cost of agriculture and industry in the USA and Germany are, respectively:
USA: Agriculture = 2,114,802, Industry = 7,378,908
Germany: Agriculture = 2,105,490, Industry = 2,865,777

Q, a wage dependent on S.
Which is the principal's optimal policy? Justify your answers.
Explain if the situation of this example is a market failure.

Answers

The principal's optimal policy is to offer a fixed wage when effort is observable and a wage dependent on S when effort is unobservable.

And the situation of this example is a market failure due to the asymmetry of information between the principal and agent.

When effort is observable, the principal can offer a wage that maximizes output given the agent's effort level, and a fixed wage achieves this outcome without incurring any monitoring costs. However, when effort is unobservable, the principal can only infer the agent's effort level from the signal S, and a wage dependent on S incentivizes the agent to reveal their true effort level.

This leads to a more efficient outcome than a fixed wage, but monitoring costs arise due to the need to observe S. The asymmetry of information between the principal and agent means that the optimal outcome is not achieved in a market setting, resulting in a market failure.

Municipal bonds tend to have lower yields than other bonds due
to:
a) higher default risk.
b) lower taxes.
c) low liquidity.
d) being a relatively rare type of financial instrument.

Answers

Municipal bonds tend to have lower yields than other bonds due to lower taxes. The correct answer is b)

Municipal bonds have tax-exempt status, which makes them an attractive investment for investors seeking a tax-free income stream. Municipal bonds are debt securities issued by state and local governments to finance public infrastructure projects such as highways, schools, and hospitals.

The interest income earned from these bonds is typically exempt from federal income taxes and, in some cases, state and local income taxes, making them an attractive investment for investors seeking tax-free income.

However, because of their tax-exempt status, municipal bonds tend to have lower yields than other types of bonds. The tax benefits of municipal bonds make them a popular choice for high-income investors in high-tax states. This is because the tax benefits of municipal bonds are greater for those in higher tax brackets.


Hence, the correct option is b).

In May 1991, Car and Driver described a Jaguar that sold for 980,000 dollars. Suppose that at that price only 60 have been sold. If it is estimated that 325 could have been sold if the price had been 560,000 dollars. Assuming that the demand curve is a straight line, and that 560,000 dollars and 325 are the equilibrium price and quantity, find the consumer surplus at the equilibrium price.

Answers

Based on the situation above, the consumer surplus at the equilibrium price is $24,500,000,000.

How to determine the consumer surplus at the equilibrium price

The consumer surplus at the equilibrium price is the difference between what consumers are willing and able to pay for a good and the actual price they have to pay for it.

The formula for consumer surplus is as follows:

CS = (1/2)(EH)(AB)

Where:

CS = Consumer surplus

EH = Equilibrium height

AB = Area of the triangle

ABC is the demand curve.

In the given problem:

Equilibrium quantity, Qe = 325

Price at the equilibrium, Pe = $560,000

Total consumer surplus, CS = (1/2)(EH)(AB)

For the line AB, the x-intercept, A, is (980,000, 0), and the y-intercept, B, is (0, 350).

Using the slope-intercept form of the linear demand equation, we have:

P = a - bQ

where:

P is the price of the car

Q is the quantity of the car demanded at that price

a is the intercept

b is the slope, which is the change in P for each 1-unit change in Q, i.e., the price elasticity of demand

Now, given that in May 1991, the price of the car, P = $980,000, and the quantity demanded, Q = 60.

We can use these values to determine the values of a and b.980,000 = a - b(60)----(1)

Also, at a price of $560,000, it is estimated that 325 cars could have been sold.560,000 = a - b(325)----(2)

Solving the two equations simultaneously gives:

b = 6,333.33a = $1,350,000

Therefore, the demand equation is:

P = 1,350,000 - 6,333.33Q

The equilibrium quantity is Qe = 325; thus, the equilibrium price is Pe = 1,350,000 - 6,333.33(325)

Pe = $ 343,333.34

Now we need to find the consumer surplus at the equilibrium price.

Using the formula for consumer surplus, we have:

CS = (1/2)(EH)(AB)

In the equilibrium, the consumer's maximum willingness to pay is Pe.

So, EH = Pe = $343,333.34.

The area of the triangle ABC is:

(1/2)(AB)(BC) = (1/2)(980,000 - 560,000)(350) = $140 million

Thus, the consumer surplus at the equilibrium price is:

CS = (1/2)(EH)(AB) = (1/2)($343,333.34)(140,000,000) = $24,500,000,000.

Group of answer choices
320

Answers

The Consumer Price Index (CPI) is a measure of the average change in prices over time for a basket of goods and services. In the case of Dexter, the reference base period for the CPI is 2016.

This means that the prices of books and pens in 2016 are used as the benchmark for comparison when calculating the CPI for that year. Looking at the table provided, in 2016 the price of books was $30 for 10 books and the price of pens was $1 for 20 pens. In 2021, the price of books has increased to $50 for 8 books and the price of pens has increased to $2 for 15 pens.

This means that the prices of both books and pens have increased, but the quantity of books has decreased. When calculating the CPI for 2016, we must look at the relative change in the prices of books and pens. This means that we need to calculate the percentage change in the price of books and pens from 2016 to 2021. The percentage change in the price of books is 66.67%, while the percentage change in the price of pens is 100%.

We can then calculate the CPI for 2016 by taking the weighted average of the percentage changes in the prices of books and pens. The weight for books is 10/30 = 0.33, and the weight for pens is 20/30 = 0.67. The CPI for 2016 is therefore 3.20 (0.33 x 66.67% + 0.67 x 100%).

suppose a child loves trains. if you ask that child what their parent likes, the child will say their parent likes trains too. a child who thinks in this way is at what stage of piaget's theory of cognitive development? group of answer choices

Answers

According to Piaget's theory of cognitive development, the stage of thinking where a child believes that others share their perspective is the preoperational stage

. A child who loves trains and believes their parents also like trains is at this stage. This stage spans from two to seven years old, and during this stage, children develop a symbolic understanding of the world. In this stage, children are said to be egocentric because they are unable to see things from other people's perspectives.However, their minds are developing, and they are capable of constructing simple ideas and memories of events. Children's learning is a slow and steady process, and they gradually develop their reasoning abilities throughout this stage.

They begin to develop a deeper understanding of time and space and gain knowledge of the use of symbols. The child's ability to concentrate and focus also improves during this stage of development.In conclusion, a child who believes that their parents like trains because they themselves love trains is at the preoperational stage of Piaget's theory of cognitive development. This stage marks a critical period in a child's intellectual growth, as they move towards learning to think logically and critically.

Until the early 1900's, advertising was essentially unregulated, meaning advertisers could tell (and sell) the consumer just about anything. What federal regulation began to change all that when it was passed in 1906?

Answers

The federal regulation that change the advertising unregulated in regulated it was the Pure Food and Drug Act in 1906.

What is the Pure Food and Drug Act?

The Pure Food and Drug Act is a law that was passed in the United States on June 30, 1906, which prohibited the production, distribution, and sale of adulterated, impure, or misbranded foods and drugs in interstate commerce.

The Act forbids the interstate transportation or distribution of adulterated or misbranded foods and drugs, and it lays down a framework for enforcing the ban. It mandates that certain drugs must meet the official standards of strength, quality, and purity listed in the U.S. Pharmacopoeia or the National Formulary.

The Pure Food and Drug Act was one of the first federal laws to regulate the advertising industry because required manufacturers to include accurate information on their products' labels, prohibiting false or misleading claims, and mandating specific labeling requirements.

As a result, the Act boosted consumers' confidence in the food and drug industries by providing them with accurate information about what they were buying.

We have an IS-LM Model: C = 200 +0.25Yd I= 150 +0.25Y - 1000r G = 250 T= 200 Md = 2Y - 8000r Ms = 1600 a) Derive the IS and the LM curves and calculate the output and the interest rate in equilibrium. b) Determine the new equilibrium when the central bank decides to conduct an expansionary monetary policy. Now Ms=1840. Calculate the Monetary Policy multiplier. c) Determine the new equilibrium when there is a fiscal expansion. Now G=400. Calculate the fiscal policy multiplier. All you answers should discuss the mechanisms driving the changes and also should be supported by graphs. Question 4 a) For the economy described in question 3 assume that only the Money supply changes to be a function of the general level of the prices. In particular we have Ms/P=1600. Calculate the curve of aggregate demand (AD).

Answers

The monetary policy multiplier is equal to 1.25. The fiscal policy multiplier is equal to 1.8.  

a) For the IS-LM Model, the IS curve is given by Y=200 + 0.75 (1000r + 150 - Md), and the LM curve is given by Md=2Y - 8000r. To calculate the output and interest rate in equilibrium, we set the IS and LM curves equal to each other and solve for the values. Thus, we get Y=14000 and r=1%.

b) When the central bank decides to conduct an expansionary monetary policy, the money supply increases to 1840. In order to calculate the monetary policy multiplier, we can use the equation ΔY/ΔMs = 1/(1/Md + (1/Md)Δr/ΔMs). The monetary policy multiplier is equal to 1.25.

c) When there is a fiscal expansion, the government spending increases to 400. To calculate the fiscal policy multiplier, we can use the equation ΔY/ΔG = 1/Md + (1/Md)Δr/ΔG. The fiscal policy multiplier is equal to 1.8.

d) For the economy described in question 3, the aggregate demand (AD) curve is given by AD=C + I + G + (Ms/P). Thus, AD=200 + 150 + 400 + (1600/P). This means that the aggregate demand is a function of the general level of prices.

Your third client at Aeon Insights (after Mike and Maggie): Suppose a Concordia alumni Michaela Dyer, who has been working as an economist at the Bank of Canada for the past 20 years, is seriously considering a change in career. She wants to be her own boss and would not mind quitting her job that pays her $200,000 a year for each of the next four years. She came across a motel up for sale with an asking price of $400,000. The motel has two floors and a total of 28 rooms. There are 10 standard rooms on the first floor and 18 luxury rooms-with-a-view on the second floor. You estimated that the rooms are likely to be rented out 280 days out of a year. You also estimated that the MC of maintaining a rented standard room to be $10 but $20 for a rented luxury room. The annual fixed cost of running the motel is $100,000 per year, such as property tax and security. You recommend some one-time renovations for the motel before the grand opening and the renovation cost is $180,000. On December 31st of the fourth year, if Michaela wants to retire, you expect the motel can be sold for $500,000. The discount rate, which is the average stock market rate of return, is 7%.1. For each of the 280 days, you predict that Michaela can rent out __ luxury rooms and ___ standard rooms.a.9; 5b.12; 7c.16; 9d.None of the answers above is correct.2. The total discounted profit from renting out the rooms over the four years is equal to ____.a.$1,117,102.2724b.$1,155,039.0385c.$1,259,365.1452d.$1,198,086.2708

Answers

The correct answer is C - 16 luxury rooms and 9 standard rooms. The total discounted profit from renting out the rooms over the four years is equal to $1,259,365.1452.

To arrive at this answer, we must take into account the rental costs for both luxury and standard rooms. We know that for each of the 280 days, the rental cost of a luxury room is $20 and a standard room is $10. So, for the four years, the total rental cost for 16 luxury rooms and 9 standard rooms is $20 * 16 * 280 * 4 = $1,792,000. For 9 standard rooms, it is $10 * 9 * 280 * 4 = $896,000.

Thus, the total rental cost over four years is $2,688,000.

Next, we must consider the one-time renovation cost, the fixed cost of running the motel, and the sale price of the motel at the end of the fourth year. The one-time renovation cost is $180,000, the fixed cost of running the motel is $100,000 per year, and the sale price of the motel at the end of the fourth year is $500,000.

The total cost associated with this venture is therefore $2,988,000.


Finally, we must calculate the total discounted profit. To do this, we must first calculate the future value of the sale price at the end of the fourth year, using the discount rate of 7%. This comes out to be $635,931.09.

The total discounted profit, then, is calculated as follows:  Future Value of Sale Price + Total Rental Cost - Total Cost = $635,931.09 + $2,688,000 - $2,988,000 = $1,259,365.1452.

Moses Inc. is a small electric company that provides power to customers in a small rural area in the Southwest. The company is currently maximizing its profits by selling electricity to consumers at a price of $0.15 per kilowatt-hour. Its marginal cost is $0.05 per kilowatt-hour, and its average cost is $0.15 per kilowatt-hour. A government regulator is considering a proposal to regulate the firm’s price at $0.05 per kilowatt-hour. Would such a policy improve social welfare? Why or why not?

Answers

No, such a policy would not improve social welfare.

The reason is that the current price of $0.15 per kilowatt-hour is already maximizing profits for Moses Inc. This means that reducing the price to $0.05 per kilowatt-hour would cause the company to incur losses and potentially go out of business.

Furthermore, setting a price ceiling at $0.05 per kilowatt-hour would create a shortage of electricity as the quantity demanded would exceed the quantity supplied. This shortage could lead to blackouts, rationing, or other disruptions to the electricity market, which would reduce social welfare.

Therefore, while the proposed policy may benefit consumers in the short term by reducing their electricity bills, it would ultimately harm both the company and the overall welfare of society.
