    The primary antitrust statute in the United States is the:

    • NLRA of 1935

    • Sherman Antitrust Act of 1890

    • SEC Act of 1933

    • Federal Reserve Act of 1913

    Correct Answer
    A. Sherman Antitrust Act of 1890
    Explanation
    The correct answer is the Sherman Antitrust Act of 1890. This legislation is considered the primary antitrust statute in the United States. It was enacted to prevent monopolies and promote fair competition in the marketplace. The Sherman Antitrust Act prohibits certain business practices that restrain trade, such as price-fixing, bid-rigging, and monopolistic mergers. It has been instrumental in regulating and breaking up large corporations that engage in anti-competitive behavior, ensuring a level playing field for businesses and protecting consumer interests.

    A market situation in which there are a few large firms is called

    • Monopolistic competition

    • Monopoly

    • Oligopoly

    • Imperfect competition

    Correct Answer
    A. Oligopoly
    Explanation
    Oligopoly refers to a market structure characterized by a few large firms dominating the market. In such a situation, these firms have significant control over the market and can influence prices and competition. Unlike monopoly, where there is only one dominant firm, or monopolistic competition, where there are many small firms, oligopoly represents a balance between competition and concentration of power. This market structure often leads to interdependence among the firms, as their actions and decisions can have a significant impact on each other and the overall market.

    Rate this question:

  • 4. 

    In an oligopolistic market, each firm

    • Faces a perfectly elastic demand function

    • Produces at minimum average cost in the long run

    • Has a constant marginal cost

    • Must consider the reaction of rival firms when making a pricing or ouptput decision

    Correct Answer
    A. Must consider the reaction of rival firms when making a pricing or ouptput decision
    Explanation
    In an oligopolistic market, firms have a significant influence on the market due to their size and market share. As a result, any decision made by one firm, such as pricing or output decisions, can have a significant impact on the other firms in the market. Therefore, each firm must consider the reaction of rival firms when making these decisions to avoid potential retaliation or negative consequences. This is necessary to maintain a competitive position and avoid losing market share or profitability.

  • 5. 

    The most common reason for the existence of oligopolies is:

    • Diseconomies of scale

    • Economies of scale

    • Ease of entry

    • Advertising

    Correct Answer
    A. Economies of scale
    Explanation
    Oligopolies are characterized by a small number of large firms dominating a market. The existence of oligopolies can be attributed to economies of scale. Economies of scale refer to the cost advantages that firms experience as they increase their production levels. In an oligopoly, large firms can take advantage of economies of scale to lower their average costs and maintain a competitive edge. This makes it difficult for new firms to enter the market and compete effectively. Therefore, economies of scale play a crucial role in explaining the existence of oligopolies.

    Rate this question:

  • 6. 

    Which type of regulation applies to all firms in the economy, as opposed to only covering specific industries?

    • Statutory regulation

    • Rate regulation

    • Economic regulation

    • Social regulation

    Correct Answer
    A. Social regulation
    Explanation
    Social regulation is a type of regulation that applies to all firms in the economy, regardless of the industry they belong to. It focuses on protecting public welfare, health, safety, and the environment. This type of regulation aims to ensure that businesses operate in a socially responsible manner and comply with certain standards and guidelines set by the government. It covers various areas such as labor practices, consumer protection, environmental protection, and occupational health and safety. Social regulation is different from other types of regulation, such as statutory regulation or rate regulation, which may only apply to specific industries or sectors.

    Rate this question:

  • 7. 

    Within a game theory model, if a change in decision-making raises corporation A's profits by $50 and lowers corporation B's profits by $50, the game is a

    • Positive-sum game

    • Zero-sum game

    • Cooperative game

    • Negative-sum game

    Correct Answer
    A. Zero-sum game
    Explanation
    In a zero-sum game, the total gains and losses of the players involved are balanced. This means that any gain for one player is exactly offset by an equal loss for the other player. In this case, the change in decision-making results in a $50 increase in profits for corporation A, but a $50 decrease in profits for corporation B. Since the gains and losses cancel each other out, the overall outcome is a zero-sum game.

    The first antitrust law in the United States was the:

    • Clayton Act

    • Robinson-Patman Act

    • FTC Act

    • Sherman Act

    Correct Answer
    A. Sherman Act
    Explanation
    The correct answer is the Sherman Act. The Sherman Act was the first antitrust law in the United States, enacted in 1890. It aimed to prevent monopolies and promote fair competition in business. The act prohibits activities that restrict trade, such as price-fixing and monopolistic practices, and allows the government to take legal action against companies engaged in anti-competitive behavior. The Sherman Act laid the foundation for subsequent antitrust legislation and remains a crucial tool in regulating business practices in the United States.

    Rate this question:

  • 9. 

    Suppose an industry has total sales of $25 million per year.  The two largest firms have sales of $6 million each, the third-largest firm has sales of $2million, and the fourth largest firm has sales of $1 million.  The four-firm concentration ratio for this industry is

    • 36 percent

    • 60 percent

    • 25 percent

    • 50 percent

    Correct Answer
    A. 60 percent
    Explanation
    The four-firm concentration ratio measures the combined market share of the four largest firms in an industry. In this case, the total sales of the two largest firms are $6 million each, the third-largest firm has sales of $2 million, and the fourth largest firm has sales of $1 million. Adding these up, the combined sales of the four largest firms is $6 million + $6 million + $2 million + $1 million = $15 million. To calculate the concentration ratio, we divide the combined sales of the four largest firms by the total industry sales and multiply by 100. Therefore, the concentration ratio is ($15 million / $25 million) x 100 = 60 percent.

    Rate this question:

  • 10. 

    An industry's equilibrium wage rate is established:

    • By the slope of the industry demand curve for labor alone

    • By the industry supply curve for labor alone

    • By the Labor Deparment and based on the cost of living in the area

    • By the intersection of the industry supply and demand curves for labor

    Correct Answer
    A. By the intersection of the industry supply and demand curves for labor
    Explanation
    The equilibrium wage rate in an industry is determined by the intersection of the industry supply and demand curves for labor. This is because the supply curve represents the quantity of labor that workers are willing to provide at different wage rates, while the demand curve represents the quantity of labor that employers are willing to hire at different wage rates. The point where these two curves intersect represents the wage rate at which the quantity of labor supplied equals the quantity of labor demanded, resulting in a stable equilibrium.

    The Federal Trade Commission Act was designed to:

    • Prohibit bundling

    • Limit company profits from foreign sales

    • Prohibit cutthroat pricing

    • Increase foreign trade

    Correct Answer
    A. Prohibit cutthroat pricing
    Explanation
    The correct answer is "prohibit cutthroat pricing." The Federal Trade Commission Act was enacted to prevent unfair methods of competition in commerce, including practices like cutthroat pricing. Cutthroat pricing refers to a strategy where a company sets its prices significantly lower than its competitors in order to drive them out of business. This practice can harm competition and consumers, and the FTC Act aims to prohibit such anti-competitive behavior.

    Rate this question:

  • 12. 

    The market demand curve for labor:

    • Slopes upward

    • Slopes downward

    • Is horizontal at the going wage rate

    • Is vertical at the existing supply of labor

    Correct Answer
    A. Slopes downward
    Explanation
    The market demand curve for labor slopes downward because as the wage rate increases, employers are willing to hire fewer workers. This is because higher wages increase the cost of labor for businesses, leading them to reduce their demand for workers. Additionally, as wages increase, workers may choose to work fewer hours or exit the labor market altogether, further reducing the demand for labor. Therefore, the downward slope of the market demand curve for labor reflects the inverse relationship between wages and the quantity of labor demanded.

    Monopolies and oligopolies both erect barriers to entry through the use of:

    • Advertising

    • Price cutting

    • Franchising

    • Patents

    Correct Answer
    A. Patents
    Explanation
    Monopolies and oligopolies can use patents to erect barriers to entry. A patent grants exclusive rights to an inventor for a certain period, preventing others from using, making, or selling the patented product or process without permission. By obtaining patents, monopolies and oligopolies can limit competition by preventing others from entering the market with similar products or technologies. This allows them to maintain their market dominance and potentially charge higher prices. Therefore, patents serve as a tool to restrict competition and protect the market power of monopolies and oligopolies.

    The Sudsy Soda Company will not sell its soft drinks to a restaurant unless that business also buys paper cups from Sudsy.  This requirement is an example of:

    • Price differentiation

    • Complementary pricing

    • Product versioning

    • Tie-in sales

    Correct Answer
    A. Tie-in sales
    Explanation
    Tie-in sales refers to a strategy where a company requires customers to purchase additional products or services in order to obtain the desired product. In this case, the Sudsy Soda Company is using tie-in sales by only selling their soft drinks to restaurants if they also purchase paper cups from Sudsy. This strategy helps Sudsy increase their sales of paper cups by bundling them with their soft drinks, creating a mutually beneficial relationship between the company and the restaurant.

    The primary measure of monopoly power is called the:

    • Litmus text

    • Monopoly measure

    • Robinson-Patman Act ratio

    • Market share test

    Correct Answer
    A. Market share test
    Explanation
    The market share test is the primary measure of monopoly power because it examines the percentage of a market controlled by a single firm. This test determines the level of market concentration and the potential for anti-competitive behavior. A high market share indicates a greater ability to influence prices and restrict competition, suggesting a stronger monopoly power. Therefore, the market share test is a crucial tool for assessing the extent of monopoly power in a given market.
