Overall, economists believe that deregulation of industries formerly subjected to industrial regulation (e.g. airlines)

has produced large net benefits for consumers and society.

NAFTA

has reduced most trade barriers between Canada, Mexico, and the United States.

Real wages in the United States until the early 2000-s

have increased at about the same rate as increases in output per worker.

Harry owns a barbershop and charges $6 per haircut. By hiring one barber at $10 per hour, the shop can provide 24 haircuts per eight-hour day. By hiring a second barber at the same wage rate, the shop can now provide a total of 42 haircuts per day. Harry should

hire the second barber because he will add $28 to profits.

The antitrust laws are based on the

idea that competition leads to greater economic efficiency than does a monopoly.

A constant-cost industry is one in which

if 100 units can be produced for $100, then 150 can be produced for $150, 200 for $200, and so forth.

Suppose that two firms in an industry that has a Herfindahl index of 1,000 announce a merger. The U.S. Justice Department concludes the merger will boost the index to 1,050. The antitrust authorities will most likely

ignore this merger because of the relatively small size of, and increase in, the Herfindahl index.

Country A limits other nation's exports to Country A to 1,000 tons of coal annually. This is an example of a(n)

import quota.

Suppose the United States sets a limit on the number of tons of sugar that can be imported each year. This is an example of a(n)

import quota.

An excise tax on an imported good that is not produced domestically is called a

import tariff.

In 2015, the United States

imported more goods than it exported.

Increases in the productivity of labor result partly from

improvements in technology.

The MR = MC rule applies

in both the short run and the long run.

To economists, the main difference between the short run and the long run is that

in the long run all resources are variable, while in the short run at least one resource is fixed.

In the United States cartels are

in violation of the antitrust laws.

An industry is comprised of six firms (A, B, C, D, E, F). Firms A, B, C, and D each sells 20% of the industry output, while firms E and E each has 10% market share. If all the firms in the industry merged into a single firm, then the Herfindahl index will

increase from 1800 to 10,000

Marginal revenue product (MRP) of labor refers to the

increase in total revenue resulting from hiring one more unit of labor.

Construction workers frequently sponsor political lobbying in support of greater public spending on highways and public buildings. One reason for this is to

increase the demand for construction workers.

Other things equal, patents

increase the expected rate of return on an R&D expenditure.

If a purely competitive constant-cost industry is realizing economic profits, we can expect industry supply to

increase, output to increase, price to decrease, and profits to decrease.

Assume the XYZ Corporation is producing 20 units of output. It is selling this output in a purely competitive market at $10 per unit. Its total fixed costs are $100 and its average variable cost is $3 at 20 units of output. This corporation

is making an economic profit of $40.

Refer to the diagram. In equilibrium the firm

is making an economic profit of bd per unit (of output produced).

The marginal revenue product (MRP) curve for labor for a firm

is the firm's labor demand curve.

As it relates to international trade, dumping

is the practice of selling goods in a foreign market at less than cost.

The minimum efficient scale of a firm

is the smallest level of output at which long-run average total cost is minimized.

Answer the question using the accompanying cost ratios for two products, fish (F) and chicken (C), in countries Singsong and Harmony. Assume that production occurs under conditions of constant costs and that these are the only two nations in the world. Singsong: 1 unit of fish costs 2 units of chicken Harmony: 1 unit of fish costs 4 units of chicken In Singsong the domestic real cost of each chicken

is ½ fish.

If a firm increases all of its inputs by 10 percent and its output increases by 10 percent, then

it is encountering constant returns to scale

According to some supporters of the minimum wage, it has very small or even nonexistent negative employment effects because

it reduces turnover among minimum-wage workers, prompts employers to use them more efficiently, and thus raises their average productivity.

The demand curve of an oligopolist can be viewed to have different levels of elasticity (describbed by a kinked-demand curve). This is based on the assumption that

its competitors will follow its price cut but ignore a price increase.

If a firm decides to produce no output in the short run, its costs will be

its fixed costs

If a firm is hiring a certain type of labor inputs under purely competitive conditions,

its labor supply and marginal labor (resource) cost curves will coincide and be perfectly elastic.

Suppose that a union successfully negotiated a 10 percent wage increase and the quantity of labor demanded decreased by 10 percent. Given a fixed labor demand curve, we can conclude that

labor demand is unit-elastic.

Assume the price of capital doubles and, as a result, firms make no change in the relative quantities of capital and labor they currently employ. This implies that

labor is not readily substitutable for capital.

The view that the antitrust laws should be enforced relatively leniently because of the tendency for monopoly power to erode over time is known as the

laissez-faire perspective on antitrust.

If production technology to manufacture a certain product dictates that labor and capital must be used in fixed proportions (e.g. 2 workers for 1 machine), an increase in the price of capital will cause a firm to use

less labor as a consequence of the output effect.

Round Things, Inc.'s production process exhibits economies of scale. Currently their long-run average cost is $12/unit. If Round Things doubles its use of all inputs, its new long-run average total cost will be

less than $12/unit.

A natural monopoly occurs when

long-run average costs decline continuously through the range of demand.

In a monopsonistic labor market, the employer will maximize profits by employing workers up to that point at which

marginal revenue product (MRP) equals marginal resource (labor) cost (MRC).

If a purely competitive firm is producing where product price exceeds marginal cost of production, then

the firm will fail to maximize profit and resources will be underallocated to the product.

An industry comprising a very large number of sellers producing a standardized product is known as

pure competition.

The terms of trade reflect the

ratio at which nations will exchange two goods with each other.

The rapid spread of ATMs

reduced the demand for bank tellers initially, but eventually tellers took on tasks that ATMs are not suited to handle.

A tax that takes a larger proportion of income from low-income groups than from high-income groups is a

regressive tax.

If each taxpayer paid the same lump-sum amount regardless of income level, the tax system would be

regressive.

The principle of comparative advantage indicates that mutually beneficial international trade can take place only when

relative costs of production differ between nations.

Assume that the owners of the only gambling casino in Wisconsin spend large sums of money lobbying state government officials to protect their gambling monopoly. Economists refer to these expenditures as

rent-seeking.

The fact that monopoly and monopsony exist in resource markets means that

resource price of an input does not always measure contributions to output, and hence not equal to the marginal revenue product (MRP) of the input.

Long-run competitive equilibrium

results in zero economic profits.

Compensating differences in wages

reward workers differently based on differences in the desirability of jobs.

If firms E and Fin this table merged into a single firm, the Herfindahl index would Firm . Market Share(%) A 20 B 20 C 20 D 20 E 10 F 10

rise, but the four-firm concentration ratio would remain unchanged.

Long-run real wages in the United States have

risen because growth in the demand for labor has exceeded growth in the supply of labor.

Refer to the diagram. This firm's demand and marginal revenue curves are based on the assumption that

rivals will ignore a price increase but match a price decrease.

Taxes on commodities or on purchases are known as

sales and excise taxes.

The main difference between sales and excise taxes is that

sales taxes apply to a wide range of products, while excise taxes apply only to a select group of products.

A patent is the legal right granted to a firm that allows it to

sell its new product exclusively for a given number of years.

Suppose a technological improvement increases the productivity of a firm's capital and, simultaneously, its workers' union negotiates a wage increase. We can predict that

the firm will use relatively more capital and relatively less labor.

Sales and excise taxes are levied on retailers, but retailers add these taxes to the prices of their products. This illustrates the

shifting of taxes to consumers.

A craft union (e.g. the association of lawyers) attempts to increase wage rates by

shifting the market labor supply curve to the left.

"Offshoring" refers to

shifting work overseas that was previously done domestically.

Refer to the diagram, which shows the domestic demand and supply curves for a specific standardized product in a particular nation. If the world price for this product is $0.50, this nation will experience a domestic (y axis: price, .50, 1.00, $1.60. x axis: quantity; 120, 200, 290)(supply and demand lines)

shortage of 160 units, which it will meet with 160 units of imports.

Suppose a firm in a purely competitive market discovers that the price of its product is above its minimum AVC point but everywhere below ATC. Given this, the firm

should continue producing in the short run but leave the industry in the long run if the situation persists.

A competitive employer is using labor in such an amount that labor's marginal revenue product (MRP) is $10 and its wage rate is $8. This firm

should hire more labor because this will increase profits.

Assume that an appliance manufacturer is employing variable resources X and Y in such amounts that the marginal revenue product (MRPs) of the last units of X and Y employed are $100 and $60, respectively. Resource X can be hired at $50 per unit and resource Y at $20 per unit. The firm

should hire more of both X and Y.

Marginal costs of production for a producer may be very small due to its product's ability to satisfy a large number of consumers at the same time (as for Microsoft with its Windows Opearting System). This characteristic of a product is called

simultaneous consumption.

Past costs that are not affected by new decisions are known as

sunk costs

Suppose that government imposes a specific excise tax on product X of $2 per unit and that the price elasticity of demand for X is unitary (coefficient = 1). If the incidence of the tax is such that consumers pay $1.80 of the tax and the producers pay $.20, we can conclude that the

supply of X is highly elastic.

Suppose that government imposes a specific excise tax on product X of $2 per unit and that the price elasticity of demand for X is unitary (coefficient = 1). If the incidence of the tax is such that the producers of X pay $1.75 of the tax and the consumers pay $.25, we can conclude that the

supply of X is highly inelastic.

Refer to the diagram, which shows the domestic demand and supply curves for a specific standardized product in a particular nation. If the world price for this product is $1.60, this nation will experience a domestic

surplus of 160 units, which it will export.

A progressive tax is such that

tax rates are higher the greater one's income.

If enforcement of antitrust laws cause a pure monopoly firm to be divided into two separate firms each having equal market share, then

the Herfindahl index would drop and the industry will evolve from monopoly to oligopoly

Which one of the following acts declared "every contract, combination . . . or conspiracy, in restraint of trade or commerce among the several states . . . to be illegal"?

the Sherman Act of 1890

The long run is characterized by

the ability of the firm to change all its resources, viz. plant size.

Marginal product of a worker is

the amount an additional worker adds to the firm's total output.

The long run is a period of time, or a time frame, in which

the amount of all resources can be varied.

Refer to the diagram. The vertical distance between ATC and AVC reflects

the average fixed cost at each level of output.

Refer to the diagram for a purely competitive producer. The firm's short-run supply curve is

the bcd segment and above on the MC curve.

Suppose that Joe sells pork in a purely competitive market. The market price of pork is $3 per pound. Joe's marginal revenue from selling the 12th pound of pork would be

$3

The accompanying table applies to a purely competitive industry composed of 100 identical firms. If each of the 100 firms in the industry is maximizing its profit, each must have a marginal cost of Quantity Demanded, Price, Quantity Supplied 400,000 $5 800,000 500,000 4 700,000 600,000 3 600,000 700,000 2 500,000 800,000 1 400,000

Harry owns a barbershop and charges $6 per haircut. By hiring one barber at $10 per hour, the shop can provide 24 haircuts per eight-hour day. By hiring a second barber at the same wage rate, the shop can now provide a total of 42 haircuts per day. The marginal product (MP) of the second barber is

18 haircuts.

If you would have to pay $5,000 in taxes on a $25,000 taxable income and $7,000 on a $30,000 taxable income, then the marginal tax rate on the additional $5,000 of income is

40 percent, and the average tax rate is about 23 percent at the $30,000 income level.

Which of the following is true under conditions of pure competition?

No single firm can influence the market price by changing its production level.

Refer to the diagram, where Sd and Dd are the domestic supply and demand for a product and Pc is the world price of that product. With a per-unit tariff in the amount PcPt, price and total quantity sold will be

Assume that the market for corn is purely competitive, and currently, firms growing corn are suffering economic losses. In the long run, we can expect

some firms to exit, causing the market price of corn to rise.

Refer to the diagram, which relates to Firm X. Suppose X implements an innovative new production method that shifts its total product curve from TP 2 to TP 1. Other things equal,

the average total cost of X's output would decline.
