• Definition: In a monopoly, a single company controls the entire market for a product or service, without any close competitors.
• Example: In many regions, utility companies (such as those providing water or electricity) are monopolies because they are the only suppliers of these essential services.

• Definition: Significant obstacles prevent other firms from entering the market, such as high startup costs, control over essential resources, or strict regulations.
• Example: The pharmaceutical industry often has high barriers to entry due to extensive R&D costs and regulatory approval processes.

• Definition: The monopolistic firm has the power to set prices since there are no competitors to offer lower prices.
• Example: De Beers historically controlled the diamond market and could set prices without concern for competitors.

• Definition: The product or service offered is unique with no close substitutes, making the firm the sole provider.
• Example: Microsoft's Windows operating system had few close substitutes in the 1990s and early 2000s, giving it a near-monopoly in the PC operating system market.

• Definition: Consumers have few alternatives, so demand for the product does not change significantly with price increases.
• Example: Life-saving drugs often have inelastic demand because patients need them regardless of price.

• Definition: The monopoly can earn higher-than-normal profits because it faces no competition and can set higher prices.
• Example: A patented drug can bring in significant profits due to the lack of competition and the high value placed on the medication.

• Definition: Monopolies often do not produce at the lowest possible cost or allocate resources in a way that maximises societal welfare.
• Example: A monopolistic utility company may not have the incentive to minimise costs or innovate, leading to inefficiencies.

• Definition: Monopolies can achieve lower average costs by producing on a large scale, which smaller firms cannot easily replicate.
• Example: A large telecommunications company can spread the high cost of infrastructure over a vast number of customers, reducing the average cost per user.
