Consider 2 airplane manufacturers that compete as Cournot duopolists in the market for commercial aircraft. Arrowing (firm A) has a cost function given by ?(??)=?/???, whereas SkyTrain (firm S) has a cost function given by ?(??)=?/???^?. The market demand function for commercial airliners is given by:?=???−?? where ?is the sum of the quantity of planes available for purchase.

a)If firm A chooses output first, find the Stackelberg equilibrium quantities supplied by each firm and find the equilibrium price.

1. One of the biggest news stories of the past few months is the outbreak of COVID-19 (novel coronavirus), first in China and then throughout the world. Numerous pharmaceutical companies have begun to develop COVID-19 vaccines. If all goes well, it will be at least a year before a vaccine is developed, tested, and approved by the FDA. However, one company—Moderna Therapeutics—has beaten all of the other companies in the race so far and is the first to advance to Phase 1 clinical trials.

Suppose that Moderna is the first company to gain approval for a COVID-19 vaccine in the United States. The monthly demand for COVID-19 vaccines in the U.S. is Q = 16 – (P/6) where Q is measured in millions of vials and P is measured in dollars. Moderna’s total cost of producing Q vials of vaccine is 2Q² and Moderna’s marginal cost is 4Q.

1.A As the only company allowed to sell COVID-19 vaccines in the U.S., what price would Moderna charge for its vaccine to maximize profit? How many vials of vaccine would Moderna sell each month? What are Moderna’s monthly profits from the sale of COVID-19 vaccine?

1.B How many vials of vaccine would be produced and what price per vial would be charged if this were a perfectly competitive market?

1.C (Vaccines, like the COVID-19 vaccine being developed by Moderna, provide benefits beyond the benefits received by those vaccinated. For instance, as more people are vaccinated, the odds of disease transmission to vulnerable groups who cannot be vaccinated (e.g., infants) are reduced. Suppose the marginal social benefit of the COVID-19 vaccine is 110 – 6Q, which is greater than the marginal private benefit. Given this, what role do you think the federal government should play in vaccine development, if any, beyond the determination of safety and effectiveness associated with vaccine approval?

Consider the following statement “The Australian economy is "weak", with households weighed down by slow wages growth and higher taxes, the OECD has declared in a report that backs lower interest rates, calls for more government spending…” Use the dynamic AD-AS model to describe a longer run scenario where the government is trying to pursue higher economic growth using higher government spending, but were incorrect in their estimation of the major parameters governing long run full employment equilibrium. In your analysis discuss the implications of an incorrect scenario predicted by the government when effecting their stimulus policy on equilibrium output and (un)employment. Make sure to outline the assumptions you have made to reach your conclusion. Limited 400-500 words

A firm produces 100 computers. Its total costs are $100,000 of which fixed costs are $40,000. What are its:

1. Average Fixed Costs
2. Average Variable Costs
3. Average Total Costs
4. When it produces another computer its total costs rise to $100,800. What is the marginal cost of the 101^st computer?

French Bread Chocolates developed the following quarterly sales forecasting model:

Sales = 8.50 + 0.150 TIME - 2.70 Q1 + 1.20 Q2 + 3.5 Q3

where TIME is time period. (time is zero in the fourth quarter of 2009, time is 1 in the first quarter of 2010 and 2 in the second quarter of 2010 etc.) and Q1, Q2, and Q3 are quarterly dummy variables.

Forecast French Broad Chocolate's sales for each quarter of 2022.

1. Samirah has been appointed by a research institute to investigate what determined the price of automobiles in Ghana in 2019. She collected data on different variables including the price, mileage, repair record, weight and whether the car is a foreign or domestic one. Using Stata econometric software, she fitted a multiple linear regression and reported the following results to her superiors.

Assume in a simple example that a change occurs in an economy that produces “Good X” and that there is a decrease in the number of sellers/producers in the economy who make “Good X”. Assume that this is a competitive market, what will happen to the equilibrium price and quantity of “Good X”? Use supply and demand analysis to demonstrate your answer and be sure to provide the rationale behind what is happening and also discuss any interesting observations or outcomes. Finally, please give an example from the news of a current event in real life that relates to the economic change affecting “Good X” above and be sure to explain why it relates.

(Note: The magnitude of any supply and/or demand shifts in this example are not specified; you may want to consider the magnitude of any shifts in your analysis).
