    • Patent

    • Sole ownership of necessary resources

    • Start-up costs are too high

    Correct Answer
    A. Start-up costs are too high
    Explanation
    If Bob and Susie try to start up an airline, they will have to buy numerous costly inputs such as airplanes, staff and space in airports, etc. This will mean that they will have to charge incredibly high prices in comparison to Ryanair and Aerlingus, meaning that it will be very difficult for them to sell any seats.

    The US beer industry is dominated by two producers: Anheuser-Busch and Miller-Coors with a two firm concentration ratio of 80%. Define the term concentration ratio.

    • The alcohol content of beer

    • The ability of beer drinkers to pay attention

    • The share of industry output in sales or employment accounted for by the top firms

    Correct Answer
    A. The share of industry output in sales or employment accounted for by the top firms
    Explanation
    The concentration ratio refers to the share of industry output in sales or employment that is accounted for by the top firms. In this case, the concentration ratio of 80% indicates that Anheuser-Busch and Miller-Coors together account for 80% of the industry's output in terms of sales or employment. This suggests that these two firms have a significant level of control and dominance in the US beer industry.

    The free market ensures the efficient allocation of resources to firms. True or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The free market, or Adam Smith's concept of an "invisible hand" ensures that scarce resources are allocated among firms efficiently, assuming that factor markets are competitive and open, that all firms pay the same prices for inputs, and that all firms maximise profits.

    What is partial equilibrium analysis?

    • The condition that exists when some markets in an economy are in simultaneous equilibrium.

    • Process of examining the equilibrium conditions in individual markets and for households and firms separately.

    • The condition in which the economy is producing what people want at least possible cost.

    Correct Answer
    A. Process of examining the equilibrium conditions in individual markets and for households and firms separately.
    Explanation
    Partial equilibrium analysis refers to the process of examining the equilibrium conditions in individual markets and for households and firms separately. It involves analyzing the supply and demand dynamics, price determination, and market outcomes in specific sectors or industries, without considering the interconnections and feedback effects from other markets or the overall economy. This approach allows for a more detailed and focused analysis of the factors influencing market equilibrium and helps in understanding the behavior and decision-making of individual economic agents.

    In economic terms, what does 'horizontal differentiation' mean?

    • An object looking different when you're sitting down

    • Products differ in ways that make them better for some and worse for others

    • A product difference that appears to make it better for everyone

    Correct Answer
    A. Products differ in ways that make them better for some and worse for others
    Explanation
    Horizontal differentiation refers to the variation in products or services that makes them more suitable or preferable for certain individuals or groups while being less desirable for others. It implies that different products have distinct features or characteristics that cater to different consumer preferences or needs. This can result in a situation where a particular product may be considered superior by some consumers but not by others, depending on their specific requirements or tastes.

    What does the term duopoly describe?

    • A two-firm monopoly

    • A board game

    • A two-firm oligopoly

    • A ten-firm oligopoly

    Correct Answer
    A. A two-firm oligopoly
    Explanation
    The term "duopoly" refers to a market structure in which there are only two firms that dominate the industry. These two firms have a significant market share and often have a strong influence on pricing and competition within the market. Unlike a monopoly, where there is only one firm controlling the market, a duopoly allows for some level of competition between the two dominant firms. Therefore, the term "duopoly" accurately describes a two-firm oligopoly.

    Demand for housing in Dublin suddenly rises. Which of these answers is true? - ProProfs

    Demand for housing in Dublin suddenly rises. Which of these answers is true?

    • Unemployment would increase

    • Housing prices would fall

    • The demand curve for the housing market would shift to the left

    Correct Answer
    A. The demand curve for the housing market would shift to the left
    Explanation
    When the demand for housing in Dublin suddenly rises, it means that more people are willing and able to buy houses. This increase in demand will cause the demand curve for the housing market to shift to the right, not to the left. The leftward shift of the demand curve would indicate a decrease in demand, which is not consistent with the given scenario. Therefore, the answer "The demand curve for the housing market would shift to the left" is not true.

    A beautiful mind is a film that tells the story of John Nash, an economics nobel prize winner. What is the name given to his theory which analyses choices made by rival firms to maximise well being and anticipate reactions? - ProProfs

    A beautiful mind is a film that tells the story of John Nash, an economics nobel prize winner. What is the name given to his theory which analyses choices made by rival firms to maximise well being and anticipate reactions?

    • Nash theory

    • Game theory

    • Mind theory

    • Firm theory

    Correct Answer
    A. Game theory
    Explanation
    The correct answer is Game theory. Game theory is the name given to John Nash's theory which analyzes choices made by rival firms to maximize well-being and anticipate reactions. This theory is widely used in economics and other fields to study strategic decision-making and interactions between individuals or organizations. It provides a framework for understanding how individuals or firms make decisions in situations where the outcome depends on the choices of others.

    The Big Mac is known as the symbol of American capitalism and 17 are sold every second. To which market structure does McDonalds belong? - ProProfs

    The Big Mac is known as the symbol of American capitalism and 17 are sold every second. To which market structure does McDonalds belong?

    • Monopoly

    • Oligopoly

    • Perfect Competition

    Correct Answer
    A. Oligopoly
    Explanation
    McDonald's belongs to the market structure of oligopoly. This is because the fast-food industry is dominated by a few major players, including McDonald's, Burger King, and Wendy's. These companies have a significant market share and have the ability to influence prices and competition. The fact that McDonald's is a well-known symbol of American capitalism and sells a large number of Big Macs every second further supports its position in an oligopolistic market structure.

    Which of the following is an example of a monopoly?

    • Buying a dress on Grafton St.

    • Buying a meal on an airplane

    • Only newsagents selling naggins of vodka

    Correct Answer
    A. Buying a meal on an airplane
    Explanation
    Buying a meal on an airplane is an example of a monopoly because it refers to a situation where there is only one provider of a particular product or service. In this case, the airline has exclusive control over the food and beverage options available on the flight, giving passengers no alternative choices. This lack of competition allows the airline to set prices and control the market without any significant competition from other vendors.

    • Efficient market

    • The Industrial Revolution

    • Rawlsian justice

    • Pareto Efficiency

    • Rent-seeking behaviour

    Correct Answer
    A. Pareto Efficiency
    Explanation
    If there is no way of improving the situation of one person, without making that of another person worse, the solution found is Pareto Efficient. Because Anne and Jim swapped and both of them benefitted from it without making the other worse off, Pareto Efficiency, or Pareto Optimality, is in effect here.

    • Network Externalities

    • Price discrimination

    • Barrier to entry

    • Ownership of a scarce factor of production

    Correct Answer
    A. Network Externalities
    Explanation
    This scenario is an example of network externalities. Network externalities occur when the value of a product or service increases as more people use it. In this case, Jill's video phone becomes less valuable because none of her friends have video phones, limiting her ability to communicate with them. The value of a video phone is dependent on the network of other users, making it an example of network externalities.

    The average price of mobile phones suddenly drops by €30. Which of these answers could not be true? - ProProfs

    The average price of mobile phones suddenly drops by €30. Which of these answers could not be true?

    • There was a major technological advance

    • The supply curve for the mobile phone industry would shift to the right

    • Demand for household phones would increase

    • Demand for mobile phones would increase

    Correct Answer
    A. Demand for household phones would increase
    Explanation
    Major technological advances would reduce the price of mobile phones significantly. Cheaper phones would mean more demand for them. The supply curve would shift to the right as producers would produce more at a lower cost. Demand for household phones would not increase as people would prefer cheap mobile phones.

    Which of the following is not an example of market failure?

    • Externalities

    • Monopoly

    • Diminishing marginal utility

    • Imperfect information

    Correct Answer
    A. Diminishing marginal utility
    Explanation
    Market failure occurs when resources are allocated inefficiently. Diminishing marginal utility is the law that as a person increases consumption of a product - while keeping consumption of other products constant - there is a decline in the marginal utility that person derives from consuming each additional unit of that product, and is therefore not an example of market failure.

    The relative profitability of an industry is measured using a model developed by Michael Porter. Name this model. - ProProfs

    The relative profitability of an industry is measured using a model developed by Michael Porter. Name this model.

    • The three forces model

    • The six forces model

    • The four forces model

    • The five forces model

    Correct Answer
    A. The five forces model
    Explanation
    The correct answer is the five forces model. This model, developed by Michael Porter, is used to analyze the competitive environment of an industry. It considers five forces that shape the industry's profitability: the threat of new entrants, the bargaining power of buyers, the bargaining power of suppliers, the threat of substitute products or services, and the intensity of competitive rivalry. By assessing these forces, businesses can understand the attractiveness and profitability of an industry, and develop strategies to gain a competitive advantage.

    Markets in which entry and exit are so easy that the threat of potential entry holds down prices to competitive level are known as....

    • Threatening markets

    • Entry markets

    • Barrier markets

    • Contestable markets

    Correct Answer
    A. Contestable markets
    Explanation
    Contestable markets refer to markets where there are low barriers to entry and exit, making it easy for new firms to enter and compete with existing firms. In these markets, the threat of potential entry keeps prices competitive as existing firms cannot raise prices without the risk of new entrants entering the market and undercutting them. This concept emphasizes the importance of potential competition in maintaining competitive prices, even if there are only a few actual competitors present in the market.

    Monopolistic competition among nightclubs in Dublin may be beneficial for students because...

    • It means there is less choice

    • Bad nightclubs will be forced to close

    • It leads to a better choice

    Correct Answer
    A. It leads to a better choice
    Explanation
    Monopolistic competition is a market structure with a large number of firms, no barriers to entry, and product differentiation. If the nightclubs in Dublin had this type of market structure there would be many different clubs for students to choose from, allowing them to maximise their utility satisfaction.
