Consider the market for potatoes. You can assume perfect competition.
It is known that the market equilibrium price is $3 per kg and the market equilibrium quantity is 100,000 kg. It is known that when the price is $3 price elasticity of demand is 0.4 and price elasticity of supply is 1.1. Assume that initially the market for potatoes is in equilibrium.
a)   Draw a diagram with (downward-sloping) demand and (upward-sloping) supply schedules. Indicate the market equilibrium, consumer surplus, producer surplus and the dead-weight loss. (Remember the relation between elasticity and the absolute slope of the demand and supply schedules. You do not have to be precise, just make sure it is clear which schedule is steeper).

You answer.

b)   If the price increases by 5% what would be the percentage change of quantity demanded? What would be the new quantity demanded? If the price increases from $3 to $3.03 what would be the new quantity producers would be willing to supply?

You answer.

c)   The government decides to introduce a 10% tax on the price of potatoes. How would such a decision affect the equilibrium price (paid by consumers) and the equilibrium quantity? Explain using a clearly labelled graph. (Note that you are not required to calculate anything in this question.)

You answer.

d)   What would happen to consumer surplus, producer surplus, government revenue and the dead-weight loss when the 10% tax on the price of potatoes is implemented. Explain. Show the new consumer surplus, producer surplus, government revenue and the dead-weight loss on the graph in part c). Who bears higher tax burden, consumers or producers? Explain.

Key objective: exemplifying the limitations of the power of oligopoly due to short-term and long-term elasticities.

Setting: Imagine you are representing one of the members of the OPEC, and you are motivated by an increase of your revenue from the sale of crude oil. You have to compromise on current decision on possible output decrease as to stimulate the world price of gas. Please consider the historical relation of the reaction of the gas price at the pump to the world price of the crude oil per barrel. Please resort to the NYU STERN case on The Petroleum Market: 1970 – 2000 (via link provided below the assignment), but most of all to the research on the following issues in the summer of 2008 in the US and now, and the political debate on the energy crisis, environmental protection and renewable sources of energy.  

Instruction: As usually, please complete the assignment discussing the relevant economics concepts and applying economic tools with supporting data for problem solving in this real-life imitating simulation, and include also a memo summarizing the points of agreement to be reached and followed by OPEC unanimously, and with the compliance in the forthcoming months.

Outline: Include in the discussion the following issues with data, as the basis for your common decision to be made:

•      demand patterns for crude oil in the World

•      the price elasticity of demand for gas in the US

•      the factors influencing the price elasticity of demand for gas in the US, and possible changes in this respect (behavioral patterns)

•      the impact of price changes (on different price levels) on the revenue of crude oil exporters

•      the income elasticity of demand for gas

•      the price elasticity of supply of gas

•      the effect on the market outcome, on the market equilibrium, and on the efficiency of the market

•      the effect on the international trade, state policies, and on the economy.

Consider the world oil market, in which a cartel (OPEC) and a competitive fringe (rest of the world) are operating. Suppose that global oil demand and the supply of the competitive fringe are given by the following functions:

Qw=80-P

Qf=-60+p

suppose the cartel is comprised of 2 countries, let each countries marginal cost function be as follows:

MC1=5+2Q2

MC2=5+2Q2

1. Derive the marginal cost function (?C?) of the cartel. (2 pt)

2. Calculate the price at which the competitive fringe would be driven out of the

market (?1) and the price at which the cartel would be driven out of the market

(?2). (2 pt)

c. Due to the presence of the competitive fringe in the market, there will be a kink

point in the demand curve of the cartel. Calculate the price (?) and quantity (?) at

which this kink occurs. (2 pt)

d. Derive the demand function of the cartel to the left of the kink point quantity (i.e.,

for ?? ≤ ??�) and to right of the kink point (i.e., ?? ≥ ?). (2 pt) ????

e. Using the inverse demand function of the cartel, derive the corresponding marginal revenue function to the left of the kink point and to the right of the kink point. (2 pt)

f. Using the inverse demand and marginal revenue functions that you obtained in parts d. and e., calculate the cartel’s output (?? ) and the price charged per unit of output (??). ?? (2 pt)

7. Calculate the output of the fringe (?f ) at this price, along with the total output (?? + ?? ) supplied in the global oil market. (2 pt)

8. Calculate the output of each of the two members of the cartel; Q1 and Q2

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 62 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:

For example, administrative expenses should be $3,800 per month plus $43 per course plus $6 per student. The company’s sales should average $900 per student.

The company planned to run four courses with a total of 62 students; however, it actually ran four courses with a total of only 54 students. The actual operating results for September appear below:

Required:

Prepare a flexible budget performance report that shows both revenue and spending variances and activity variances for September. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

Washington County’s Board of Representatives is considering the construction of a longer runway at the county airport. Currently, the airport can handle only private aircraft and small commuter jets. A new, long runway would enable the airport to handle the midsize jets used on many domestic flights. Data pertinent to the board’s decision appear below.

In addition to the preceding data, two other facts are relevant to the decision. First, a longer runway will require a new snowplow, which will cost $165,000. The old snowplow could be sold now for $16,500. The new, larger plow will cost $14,000 more in annual operating costs. Second, the County Board of Representatives believes that the proposed long runway, and the major jet service it will bring to the county, will increase economic activity in the community. The board projects that the increased economic activity will result in $72,000 per year in additional tax revenue for the county.

In analyzing the runway proposal, the board has decided to use a 10-year time horizon. The county’s hurdle rate for capital projects is 11 percent.

Use Appendix A for your reference. (Use appropriate factor(s) from the tables provided.)

Required:

1. 1. Prepare a net-present-value analysis of the proposed long runway.
