1. Graph the following
demand schedule. Complete the chart by first inserting the formula
for the coefficient of price elasticity of demand. Calculate elasticity of demand and
show the three levels of price elasticity of demand on a graph.
Ed = (Q2 -Q1) / [Q2 - Q1)/2] / (P2 - P1) / [(P2 - P1)/2]
ED = (200/900) / (10/25) = .56 ED = (200/700) / (10/35) = 1.00 ED = (200/500) / (10/45) = 1.80
2. Draw both a perfectly
elastic and perfectly inelastic demand curve. Give an example of each

1. Use two graphs to depict the supply and demand relationship between a purely
competitive industry and a firm within the
industry making a profit. Explain the likelihood of this situation continuing.
|Entry into this market is easy and many seeing the profit
will enter the market.
Free international trade makes markets more competitive and lowers profit.
|2. Use graphs to depict a purely competitive adjustment. Explain why the adjustment takes place.|
|Suppose industry demand and supply yield an equilibrium price
P at which a firm's economic profit is zero.
1. Step 1 indicates an increase in demand to D' causing economic profit.
2. Market entry is relatively easy and this profit draws in new firms increasing supply to S'. Economic profit disappears.
3. This automatic purely competitive adjustment causes equilibrium long run economic profit for pure competition to be zero.
To many, zero long run economic profit represents an ideal economic model as all the company earns is a normal return on investment.
3. Give an economic analysis of pure competition.
A. Competition is
1. Price settles where long-run ATC is at its lowest point indicating goods are produced efficiently.
2. P = MR = MC indicating that resources are allocated efficiently as the
$'s spent by consumers (P) = the $'s received by producers (MR) = the
$ cost of producers (MC) and economic profit is zero.
1. Spillover costs (pollution) and benefits (education) aren't properly measured resulting in goods being
over and under produced.
a. Government intervention was needed to lower automobile pollution.
b. Governments supports education with grants and inexpensive loan problems to students and colleges.
2. Monopoly power develops to negate Adam Smith's "invisible hand" of competition which is required
to assure that the purely competitive adjustment occurs.
3. Eliminating economic profit makes it difficult for competitive firms to afford expensive R & D and technology.
File 24 Questions for homework
1. Contrast a monopoly making a profit with one trying to minimize its loss. What circumstances could cause a monopoly not to make a profit?
|A. ATC includes normal return on investment.
B. MC cuts ATC at lowest point.
C. Profit is maximized by producing a quantity and charging a price indicated by the intersection of MC and MR.
D. The resulting profit is not a payment for enterprise, it is economic rent.
E. High inelastic demand will result in a higher price, greater profit, and a more restricted (smaller) quantity.
| A. Rising costs and shrinking demand may result in
a monopoly not making a
B. When this happens, demand (average revenue) is always below the ATC and a loss results.
State the traditional reasons why a monopoly is not as efficient as a purely competitive firm.
Monopolies increase profits by restricting output to increase price.

1. Explain how the single-tax movement of the 19th century relates to the
idea of changing the current structure of
property taxes in America's cities.
Socialist philosophers questioned whether pure
economic rent should
a. Originally free, owners of land receive pure economic rent which is a surplus.
b. Henry George wanted to tax rent away in 19th century America.
1) Called the single-tax movement, he wanted to replace
all taxes with one tax on land.
2) Three problems exist with this philosophy.
a) Land is not free to current owners.
b) Capital improvements are necessary to make modern land useful.
c) Modern rent does perform a rationing function because land is of such differing quality.
2. Name some industries that have recently
lost their economic rent. Was this rent deserved? Why did they lose the rent?
Who was hurt? Who was helped?
Automobiles, steel, and other Rust Belt oligopolies lost much of their
economic rent during the 1970's and 1980's.
The market felt it was deserved. The primary causes were competition from overseas and an inability of company
managers to adapt to a changing environment. People hurt included owners, managers, employees, suppliers, and
their communities. Both industries recovered but President Bush found it necessary to increase tarrifs on imported
steel in 2002.Some feel antitrust activity against Microsoft is an attempt to eliminate economic rent. In the short run,
consumers and those who invested in competing companies were the primary beneficiaries. In the long run, the theory
of creative destruction indicates a more efficient system will result, and
all system participants will benefit.

1. What did Ronald Coase demonstrate concerning government involvement with
the regulation of externalities?
Give an example of the application of his theory.
Analysis by Ronald Coase revealed that government should not get involved
with disputes over externality costs
when property ownership is well-defined and the number of people involved is small. He demonstrated that
individual maximizing behavior would correct these problems. The government should only be involved when the
number of participants is so large as to make bargaining costs prohibitive. For example, the government
should not get involved in a noise pollution problem near an amusement park but should get involved with
acid rain generated in the
Midwest and falling into New England.
2. Depict how rent-seekers may obtain a surplus at the expense of the public good.
Question involves special interest groups such as PAC's, whose activities are self- serving and often at the expense of others.
3. Explain the market system solution to the problem of too much pollution.
Supply and demand are used to determine the price and quantity of some
tolerable level of pollution. Pollution is then considered a
factor of production, and like any factor, it will be purchased based upon its marginal revenue product.
File 31 Questions for homework
1. Explain how government subsidizes industry by regulating supply and demand.
A. Affecting demand
1. Tax credits, tax preferences, and loan programs for everything from agriculture to education increase taxpayers' demand by an amount related to the taxpayers' marginal tax rate.
2. Government also supports industries such as defense and agriculture with large purchases.
B. Affecting Supply
1. Supporting industries such as agriculture and education with subsidies (loans, inexpensive insurance) increases supply, lowers price, and increases quantity sold.
2. Organizations such as the Export-Import Bank of the United States,
2. What difficult market forces are encountered by the agriculture industry?
How do these forces affect supply, demand,
and the total revenue received by farmers? Explain how some of these forces were caused by government actions; some
of which succeeded, some of which failed.
Farmers sell in an uncertain market
B. Supply and Demand for agricultural products is inelastic.
C. Increased supply causes revenue to drop.
1. Demand is very inelastic as people's physical needs are limited and
lowering price will not substantially increase quantity sold.
2. Demand increases slowly for most agricultural products as many are inferior goods for which quantity demanded decreases
as income increases.
3. Supply is very inelastic in the short run as crops will only grow so fast
4. Supply is volatile because of the weather
5. Technology has caused supply to increase substantially
6. Annual supply fluctuations cause the prices farmers receive to fluctuate considerably. Fluctuating prices mean fluctuating profits.

2. Why and how was government regulation redirected during the 1980's?
A. In the 1980's, government regulation was redirecting away from maintaining competition toward social regulation.
Government regulation of industry changed direction because:
1. International competition requires companies work together in developing high-cost technology and share in its high cost
2. Many feel government should foster cooperation among competitors with an industrial policy while others feel the market
system should be left to determine factor allocations
B. Regulations protecting individuals have become more prominent.
a. Environmental Protection Agency (EPA) protects individuals from pollution (air, water, noise).
