ECON FINAL
Resource demand curves slope downward because
of the diminishing marginal product of the resource.
a. The general level of wages is higher in the United States and other industrially advanced countries because
of the high demand for labor in relation to supply.
A regressive tax is one in which
the average rate decreases as income increases
A progressive tax is one in which
the average rate increases as income increases
A proportional tax is one in which
the average rate is constant as income increases

regressive, and the incident is on the consumer if the property is used in business
The long-run downward trend in commodity prices is consistent with the idea that:
resource supplies have increased faster than resource demands
a. The supply of loanable funds is upsloping because
savers will make more funds available at higher interest rates.

Demographers have been surprised that total fertility rates have fallen below 2.0, especially because most people in most countries tell pollsters that they would like to have at least two children. What factors could be causing women in so many countries to average fewer than two children per lifetime?
Greater participation by women in the paid labor force
Suppose that the current (first) generation consists of 1 million people, half of whom are women. Assume the total fertility rate is 1.25 and the only way people die is of old age.
How big will the fourth generation (the great-grandchildren) be? 244,141 How much smaller (in percentage terms) is each generation than the previous generation? 38 percent How much smaller (in percentage terms) is the fourth generation than the first generation? 75.59
Suppose in Fiscalville there is a 0 percent tax on the first $10,000 of income, but a 15 percent tax on earnings between $10,000 and $20,000 and a 30 percent tax on income between $20,000 and $30,000. Any income above $30,000 is taxed at 45 percent.
If your income is $70,000, how much will you pay in taxes? $22,500 b. Determine your marginal tax rate: 45 percent c. Determine your average tax rate. 32 percent Is this a progressive tax? Yes
The socially optimal price (P = MC) is socially optimal because:
It achieves allocative efficiency.
GM didn't reduce employment by more than 21,000 workers because
it wanted to set the labor level where MRC equaled MRP to maximize profit.
b. The single most important factor underlying the long-run increase in average real-wage rates in the United States is
labor productivity.

b. Hospital administrators sometimes complain about a "shortage" of nurses.
The shortage is the result of low wages that occur in the monopsonized market and could be eliminated if nurses earn wages closer to their MRP.
a. In 2009 General Motors (GM) announced that it would reduce employment by 21,000 workers. What does this decision reveal about how GM viewed its marginal revenue product (MRP) and marginal resource cost (MRC)?
This decision indicates that for those 21,000 workers: the MRC was greater than the MRP.
Resource consumption per person in the United States is either flat or falling, depending on the resource. Yet living standards are rising because of technological improvements that allow more output to be produced for every unit of input used in production.
This implies that we are unlikely to run out of resources
b. Consider: "Though rent need not be paid by society to make land available, rental payments are very useful in guiding land into the most productive uses."
This statement recognizes that it makes sense to pay more for land that has a more profitable use.
a. Suppose that competing firms form an employers' association that hires labor as a monopsonist would.
This will cause a divergence of the marginal resource cost and the supply curve, which will result in fewer workers hired at a lower wage rate.
Identify the basic characteristics of each of the following market models: Pure competition:
Very large number of firms No control over price
Consider a small landscaping company run by Mr. Viemeister. He is considering increasing his firm's capacity. If he adds one more worker, the firm's total monthly revenue will increase from $54,000 to $66,000. If he adds one more tractor, monthly revenue will increase from $54,000 to $72,000. Each additional worker costs $6,000 per month, while an additional tractor would also cost $6,000 per month.

What is the ratio of the marginal revenue product of labor to the price of labor (MRPL/PL)? 2 What is the ratio of the marginal revenue product of capital to the price of capital (MRPK/PK)? 3 c. In this case, is the firm combining inputs in a way that minimizes costs? No d. Does adding an additional worker or adding an additional tractor yield a larger increase in total revenue for each dollar spent? Adding an additional tractor
Suppose that you own a 10-acre plot of land that you would like to rent out to wheat farmers. For them, bringing in a harvest involves $30 per acre for seed, $80 per acre for fertilizer, and $70 per acre for equipment rentals and labor. With these inputs, the land will yield 40 bushels of wheat per acre. Now suppose the price at which wheat can be sold is $7 per bushel and that farmers want to earn a normal profit of $10 per acre.
What is the most that any farmer would pay to rent your 10 acres? $900 What if the price of wheat rose to $8 per bushel? $1300
d. Shortcomings of the kinked-demand model include
a lack of explanation for how the initial price is set.
Workers are compensated by firms with "benefits" in addition to wages and salaries. The most prominent benefit offered by many firms is health insurance. Suppose that in 2000, workers at one steel plant were paid $35 per hour and in addition received health benefits at the rate of $7 per hour. Also suppose that by 2010 workers at that plant were paid $36.75 per hour but received $15.75 in health insurance benefits.

Incomes rise by 5 percent d. Is it possible for workers to feel as though their wages are stagnating even if total compensation is rising? Yes
A coal-fired power plant can produce electricity at an operating cost of $0.07 per kilowatt-hour when running at its full capacity of 30 megawatts per hour, $0.16 per kilowatt-hour when running at 20 megawatts per hour, and $0.24 per kilowatt-hour when running at 10 megawatts per hour. A gas-fired power plant can produce electricity at a variable cost of $0.12 per kilowatt-hour at any capacity from 1 megawatt per hour to its full capacity of 5 megawatts per hour. The cost of constructing a coal-fired plant is $50 million, but it costs only $10 million to build a gas-fired plant.
a. Consider a city that has a peak afternoon demand of 80 megawatts of electricity. If it wants all plants to operate at full capacity, what combination of coal-fired plants and gas-fired plants would minimize construction costs? Two coal-fired plants plus four gas-fired plants b. How much will the city spend on building that combination of plants? 140 million c. What will the average variable cost per kilowatt-hour be if you average over all 80 megawatts that are produced by that combination of plants? (Hint: A kilowatt is one thousand watts, while a megawatt is one million watts.) 0.08 per kilo-watt per hour d. What would the average variable cost per kilowatt-hour be if the city had instead built three coal-fired plants? 0.09 per kilowatt-hour
A purely competitive firm finds that the market price for its product is $25.00. It has a fixed cost of $100.00 and a variable cost of $15.00 per unit for the first 50 units and then $30.00 per unit for all successive units.

There are economies of scale in ranching, especially with regard to fencing land. Suppose that barbed-wire fencing costs $10,000 per mile to set up.
a. How much would it cost to fence a single property whose area is one square mile if that property also happens to be perfectly square, with sides that are each one mile long? 40,000. b. How much would it cost to fence exactly four such properties separately, which together would contain four square miles of area? 160,000. c. Now, consider how much it would cost to fence in four square miles of ranch land if, instead, it comes as a single large square that is two miles long on each side? 80,000. d. Which is more costly—fencing in the four, one-square-mile properties or the single four-square-mile property? Four, one square-mile properties
To fund its wars against Napoleon, the British government sold consol bonds. They were referred to as "perpetuities" because they would pay £3 every year in perpetuity (forever).
a. If a citizen could purchase a consol for £50 , what would its annual interest rate be? 6 percent b. What if the price were £100 ? 3 percent c. What if the price were £200 ? 2 percent d. Bonds are known as "fixed income" securities because the future payments that they will make to investors are fixed by the bond agreement in advance. Do the interest rates of bonds and other investments that offer fixed future payments vary positively or inversely with their current prices? Inversely

Eric and Kyle are fishermen with different equipment and, as a result, different costs for catching fish. Eric's costs for catching fish are $1,000 per ton for the first five tons and then $2,500 per ton for any additional tons. Kyle can harvest fish at a cost of $3,000 per ton for the first 15 tons and then $1,400 for any additional tons.
a.

Eric=5 tons Kyle=25 tons How much will the total cost of catching 30 tons be? $64,000 What will the average cost per ton be for the 30 tons? $2,133.33 c. Suppose that Eric and Kyle can both sell whatever amount of fish they catch for $3,000 per ton. Also suppose that Eric is initially given ITQs for 30 tons of fish, while Kyle is given ITQs for zero tons of fish. Suppose that Kyle is willing to pay Eric $550 per ton for as many tons of ITQs as Eric is willing to sell to Kyle. How much profit would Eric make if he used all the ITQs himself? $22,500 What if Eric sold 25 tons' worth of his ITQs to Kyle while using the other 5 tons of ITQs to fish for himself? $23750 d. What price per ton can Kyle offer to pay Eric for his 25 tons of ITQs such that Eric would make exactly as much money from that deal (in which he sells 25 tons' worth of ITQs to Kyle while using the rest to fish for himself) as he would by using all 30 tons of ITQs for himself? $500 per ton ITQ's
Suppose that the demand for loanable funds for car loans in the Milwaukee area is $12 million per month at an interest rate of 10 percent per year, $13 million at an interest rate of 9 percent per year, $14 million at an interest rate of 8 percent per year, and so on.

How big will the monthly shortage for car loans be if the usury limit is raised to 7 percent per year? 0 million worth of car loans per month
Suppose you have been tasked with regulating a single monopoly firm that sells 50-pound bags of concrete. The firm has fixed costs of $30 million per year and a variable cost of $2 per bag no matter how many bags are produced
a. If this firm kept on increasing its output level, would ATC per bag ever increase? No Is this a decreasing-cost industry? Yes b. If you wished to regulate this monopoly by charging the socially optimal price, what price would you charge? $2 per bag At that price, what would be the size of the firm's profit or loss? At that price, the firms loss equals 30 million. Would the firm want to exit the industry? Yes You find out that if you set the price at $3 per bag, consumers will demand 30 million bags. How big will the firm's profit or loss be at that price? 0 d. If consumers instead demanded 40 million bags at a price of $3 per bag, how big would the firm's profit or loss be? The firms profit equals 10 million Suppose that demand is perfectly inelastic at 40 million bags, so that consumers demand 40 million bags no matter what the price is. What price should you charge if you want the firm to earn only a fair rate of return? Assume as always that TC includes a normal profit. $2.75 a bag
You are currently a worker earning $60,000 per year but are considering becoming an entrepreneur.

Suppose the government imposes a 25 percent tax on accounting profits. This tax is only levied if a firm is earning positive accounting profits. What will your after-tax accounting profit be in the low-revenue case? -20,000 In the high-revenue case? 120,000 What will your average after-tax accounting profit be? 50,000 What about your average after-tax economic profit? -10,000 Will you now want to quit your job and try your hand at being an entrepreneur? No d. Other things equal, does the imposition of the 25 percent profit tax increase or decrease the supply of entrepreneurship in the economy? Decrease
A purely competitive wheat farmer can sell any wheat he grows for $25 per bushel. His five acres of land show diminishing returns because some are better suited for wheat production than others. The first acre can produce 1,000 bushels of wheat, the second acre 900, the third 800, and so on.

Suppose that a monopolistically competitive restaurant is currently serving 240 meals per day (the output where MR = MC). At that output level, ATC per meal is $10 and consumers are willing to pay $13 per meal.
a. What is the size of this firm's profit or loss? $720 b. Will there be entry or exit? Entry Will this restaurant's demand curve shift left or right? Left c. Suppose that the allocatively efficient output level in long-run equilibrium is 200 meals. In long-run equilibrium, suppose that this restaurant charges $11 per meal for 180 meals and that the marginal cost of the 180th meal is $9. What is the size of the firm's economic profit?$0 d. Suppose that the allocatively efficient output level in long-run equilibrium is 200 meals. In long-run equilibrium, suppose that this restaurant charges $11 per meal for 180 meals and that the marginal cost of the 180th meal is $9.

The equality of P and MC means the firm is achieving
allocative efficiency, since the industry is producing the amount of product that equates society's valuation of that product and the price of the product
The equality of P and MC means the firm is achieving A. allocative efficiency, since the industry is producing the amount of product at a price that covers its costs. B. productive efficiency, since the industry is producing the amount of product that equates society's valuation of that product and the price of the product. C. allocative efficiency, since the industry is producing the amount of product that equates society's valuation of that product and the price of the product. D. market efficiency, because price equals average cost.

a. The distinction between insurable and uninsurable risks is significant for the theory of profit because
an insurable risk does not fatally affect the profit and loss of a firm.
Changes in market prices and extraction rates
assure that resources will be extracted when their economic value is greatest.
An increase in the minimum wage could
reduce employment but increase income.
c. The kinked-demand curve explains price rigidity in oligopoly because
firms expect any change in price will lower revenue and profits.
b. If the future market price rises, all else equal, current extraction will
decrease
b. Consider: "All economic profit can be traced to either uncertainty or the desire to avoid it." This statement suggests that
demand and supply conditions are always unknown.
The factors determining resource demand differ from those determining product demand because the demand for products
depends on income and tastes, but the demand for resources is a derived demand.

Assume that a pure monopolist and a purely competitive firm have the same unit costs. In the case of a pure monopolist, resources will be allocated
inefficiently, because the monopolist does not produce at the point of minimum ATC and does not equate price and MC.
The basic model of pure competition reviewed in this chapter finds that in the long run all firms in a purely competitive industry will earn normal profits. If all firms only earn a normal profit in the long run, firms will develop new products or lower-cost production methods because they can
innovate and possibly earn an economic profit in the short run.

a. An economist's use of the term "rent" differs from everyday usage in that in the economist's understanding, economic rent
is the price paid for the use of land and other natural resources that are completely fixed in total supply
Entry and exit help to improve resource allocation because
losses result in exit and release resources to flow to markets where there are profits.
Entry and exit help to improve resource allocation because A. profits and losses indicate inefficient production. B. if firms don't respond to losses, they will miss good opportunities. C. losses result in exit and release resources to flow to markets where there are profits. D. when firms only seek profits, they can miss good opportunities.
losses result in exit and release resources to flow to markets where there are profits.

match price cuts, but ignore price increases
a. Compared to pure monopoly and pure competition, monopolistically competitive industries
might have economic profits, they will diminish as competitors enter, and there will be productive inefficiency.
The costs of a purely competitive firm and a monopoly may be different because
monopolies might experience economies of scale not available to competitive firms

The federal personal income tax is
progressive, and the incident is on the taxpayer.
The federal corporate income tax is
proportional, if the incidence is on shareholders
c. The major functions of profit include
providing an incentive for entrepreneurial initiative in combining resources to produce a good or service.
Even though both monopolists and competitive firms follow the MC = MR rule in maximizing profits, there are differences in the economic outcomes because
pure competitors are small with no market power.
b. The demand curve facing a
purely competitive firm is perfectly elastic, because the purely competitive firm may sell all that it wishes at the equilibrium price
If a monopoly can experience economies of scale, it can
reduce the price below a pure competitor and improve resource allocation.
Other things equal,
the greater the elasticities of demand and supply, the greater the efficiency loss of a particular tax.
According to the ability-to-pay principle of taxation
the higher one's income, the higher the tax, and the higher the percentage of one's income paid in tax.
There will be a greater incidence of an excise tax on consumers
the less elastic the demand.
There will be a greater incidence of an excise tax on consumers
the more elastic the supply
There is a gap in the oligopolist's marginal-revenue curve because
the slope of the demand curve changes abruptly

B. false, because a firm should only operate if it is making money. C. true, if the loss is less than fixed costs. D. false, because it could be better to stay in business in the long run.
true, if the loss is less than fixed costs.
"In the long run, monopolistic competition leads to a monopolistic price but not to monopolistic profits." This statement is
true, since P > MC, but the availability of close substitutes pushes the price of the average firm down until it equals ATC.
