a)
Explanation of Solution
When the market is perfectly competitive, the price will be zero and the quantity will be 12 as represented in the table given in the question.
In a perfectly competitive market, the price equals the MC (marginal cost) in the long-run equilibrium, so the price will be zero and the quantity will be 12.
The equilibrium point is the point where MC=MR.
Perfect competition: In perfect competition, the number of buyers and sellers is very large and the firms are usually price takers; therefore, no individual firm has the power to influence the market price.
b)
To calculate: the market price and quantity, when the market is a duopoly and the firms collude to maximize the joint profits.
b)
Explanation of Solution
In case the market is a duopoly, the price will be $12 and the quantity will be 6.
In order to maximize joint profits, the 2 firms would act as a
Going from 2 to -2 MR passes through zero after the 6th unit, making the 6th profit-maximizing quantity.
Most consumers would pay for 6 units is $ 12, so that is the profit-maximizing price.
Introduction:
Duopoly: is defined as a type of oligopoly in which two firms have exclusive or dominant control over a market. It is one of the most frequently studied forms of an oligopoly because of its simplicity.
Duopolies usually sell their products to customers in a competitive market in which the preferences and choices of an individual consumer will not affect the firm.
c)
To calculate: the firm’s total revenue when the firms split the market equally when the market is a duopoly and the firms collude to maximize the joint profits.
c)
Explanation of Solution
Total revenue is calculated by multiplying price and quantity i. e P X Q
Total revenue is $12 X 6= $72.
Therefore, by dividing this equally each firm receives $36.

- Title: Does the educational performance depend on its literacy rate and government spending over the last 10 years? In the introduction, there are four things to include:a) Clearly state your research topic follows by country’s background in terms of (population density; male/female ratio; and identify the problem leading up to the study of it, such as government spending and adult literacy rate. How does the US perform compared to other countries.b) State the research question that you wish to resolve: Does the US economic performance depend on its government spending on education and the literacy rate over the last 10 years. Define performance (Y) as the average income per capita, an indicator of the country’s economy growing over time. For example, an increase in government spending leads to higher literacy rates and subsequently higher productivity in the economy. Also, mention that you will use a sample size of 10 years of secondary data from the existing literature,…arrow_forwardTitle: Does the educational performance depend on its literacy rate and government spending over the last 10 years?

BY VIRGINIA POSTREL WOULD you rather have $1,000 for sure or a 90 percent chance of $5,000? A guaranteed $1,000 or a 75 percent chance of $4,000? In economic theory, questions like these have no right or wrong answers. Even if a gamble is mathematically more valuable a 75 percent chance of $4,000 has an expected value of $3,000, for instance someone may still prefer a sure thing. People have different tastes for risk, just as they have different tastes for ice cream or paint colors. The same is true for waiting: Would you rather have $400 now or $100 every year for 10 years? How about $3,400 this month or $3,800 next month? Different people will answer differently.
