If monopolistically competitive firms in an industry are making an economic profit, then:
New firms will enter the industry and product demand will decrease for the existing firms
The incentive to cheat is strong in a cartel because:
Each firm can increase its output and thus its profits by cutting price
If oligopolistic firms facing similar cost and demand conditions successfully collude, price and output results in this industry will be most accurately predicted by which of the following models?
The pure monopoly model
Monopolistic competition is characterized by firms:
Producing differentiated products
Suppose some firms exit an industry characterized by monopolistic competition. We would expect the demand curve of a firm already in the industry to:
Shift to the right
Monopolistic competition is characterized by excess capacity because:
Firms produce at an output level less than the least-cost output
In long-run equilibrium, a profit-maximizing firm in a monopolistically competitive industry will produce the quantity of output where:
AC = P, MR = MC < P
In the short run, the monopolistically competitive firm will experience
Economic profits or losses, but in the long run only a normal profit
Mutual interdependence means that each firm in oligopolistic industry:
Considers the reactions of its rivals when it determines its price policy
One difference between monopolistic competition and pure competition is that:

Is more elastic than the monopolist's demand curve
Which assumption is part of the model of monopolistic competition?
There is no collusion among firms
Which would be characteristic of monopolistic competition?
Relatively small market share for each firm
The kinked demand model of noncollusive oligopoly assumes that:

Increased brand loyalty toward the firm's product
In the long run, the representative firm in monopolistic competition tends to have:
Excess capacity
A representative firm in monopolistic competition will tend to make economic profits:
Or losses in the short run, but the firm will break even in the long run
Which is a likely characteristic of a differentiated oligopolistic market?
Price and output decisions of firms are interdependent
The downward-sloping demand curve of a monopolistic competitor:
Reflects product differentiation
The goal of product differentiation and advertising in monopolistic competition is to make:
Price less of a factor and product differences more of a factor in consumer purchases
Collusive control over price may permit oligopolists to:
Reduce uncertainty, increase profits, and possibly limit entry of new firms
When firms in an industry reach an agreement to fix prices, divide up market share, or otherwise restrict competition, they are practicing the strategy of:
Demand and marginal revenue curves are downward sloping for monopolistically competitive firms because:
Product differentiation allows each firm some degree of monopoly power
A monopolistically competitive industry is like a purely competitive industry in that:
Neither industry has significant barriers to entry
In the kinked demand model of noncollusive oligopoly, each firm thinks that the demand curve below the going price is:

The monopolistically competitive seller's demand curve will become more elastic the:
Larger the number of competitors
A unique feature of an oligopolistic industry is:
Mutual interdependence
A major reason that firms form a cartel is to:
Maximize joint profits
In the long run, a representative firm in a monopolistically competitive industry will typically:
Earn a normal profit, but not an economic profit
Which constitutes an obstacle to collusion among oligopolists?
A large number of firms
A characteristic of monopolistically competitive industries is that:
The entry and exit of firms causes the representative firm to break even in the long run
A positive effect of advertising for society is that it:
Provides useful information to reduce search cost for consumers
The Lorenz curve is a graph that shows the:
Degree of income inequality
A Lorenz curve showing perfect equality in the distribution of income:
Is a straight line with a 45-degree angle
A Lorenz curve shows:
The distribution of income
The greater the degree of inequality in the size distribution of income, the more bowed will be the Lorenz curve toward the
Lower right-hand corner
The diagonal line in a Lorenz curve represents perfect:
Equality in the distribution of personal income
The Gini ratio is determined by:
Dividing the area between the Lorenz curve and the diagonal by the total area below the diagonal
As the area between the Lorenz curve and diagonal gets larger, the Gini ratio:
Rises to reflect greater inequality
Which of the following Gini ratios would indicate the least amount of income inequality?
Taxes and transfer payments
Reduce the degree of income inequality
A cause of the unequal distribution of income in the United States is:
Differences in preferences and risks
The wages and salaries that people earn differ partly because of differences in:
What would be an example of how pure luck contributes to income inequality?
Selection as winner of a state lottery
The debate over income distribution focuses on the tradeoff between:
Economic efficiency and equality
The basic economic argument for greater income equality is that:
a more equal distribution of a given amount of income will increase the total utility of consumers.
A trade deficit refers to an excess of:
Goods imports over goods exports
Trade between individuals and between nations leads to:
Increased specialization
If there is no comparative advantage between two countries:
There are no gains from specialization and trade
Consider two countries which trade with each other. The degree of specialization according to their respective comparative advantages will be greater if the countries face:
Constant costs
The principle of comparative advantage indicates that mutually beneficial international trade can take place only when:
Relative costs of production differ between nations
According to the principle of comparative advantage, worldwide output and consumption levels will be highest when goods are produced in nations where:
Domestic opportunity costs are lowest
If country A has a comparative advantage in the production of good X over country B, then:
The domestic opportunity cost of producing X in country A is lower than in country B
The domestic opportunity cost of producing a television in the United States is 20 bushels of wheat. In Korea, the domestic opportunity cost of producing a television is 10 bushels of wheat. In this case:
Mutual gains from trade can be obtained if the United States imports televisions from Korea and Korea imports wheat from the United States
The domestic opportunity cost of producing 100 barrels of chemicals in Germany is one ton of steel. In France, the domestic opportunity cost of producing 100 barrels of chemicals is two tons of steel. In this case:
Germany has a comparative advantage in the production of chemicals
If the U.S. dollar appreciates relative to the British pound, then:
The pound will depreciate relative to the U.S. dollar
There is a fall in the relative prices of Japanese goods to Americans when the:
Dollar appreciates
If an American can purchase 40,000 British pounds for $90,000, the dollar rate of exchange for the pound is:
A market in which the money of one nation is exchanged for the money of another nation is a:
foreign exchange market.
Depreciation of the dollar will:
increase the prices of U.S. imports, but decrease the prices to foreigners of U.S. exports.
Appreciation of the Canadian dollar will:
make Canada's exports more expensive and its imports less expensive.
An increase in the demand for computers leads to an increase in demand for computer programmers. This situation arises because:
