    Introduction to Monopoly

    Welcome to our exploration of monopoly in economics! A monopoly occurs when a single seller dominates the market for a unique product or service. This powerful market structure gives the monopolist significant control over prices and supply. Our introduction video provides a clear, visual explanation of this concept, making it easier to grasp. You'll see how monopolies differ from competitive markets and why they're often subject to regulation. The video highlights key characteristics like high barriers to entry and the absence of close substitutes. Understanding monopolies is crucial for grasping market dynamics and their impact on consumers and the economy. As we delve deeper, you'll learn about real-world examples and the pros and cons of monopolistic markets. Remember, while monopolies can lead to inefficiencies, they sometimes arise naturally or through innovation. Let's unpack this fascinating economic concept together!

    Definition and Key Features of Monopoly

    When we talk about market structures in economics, one of the most intriguing and often misunderstood concepts is that of a monopoly. Let's dive into the world of monopolies, explore their key features, and see how they differ from perfect competition.

    A monopoly is a market structure where a single firm or entity has complete control over the supply of a particular good or service. This means that if consumers want that specific product, they have no choice but to buy it from the monopolist. It's like having only one ice cream shop in town if you're craving ice cream, you've got to go there!

    Two special features define a monopoly: no close substitutes and barriers to entry. Let's break these down:

    1. No close substitutes: In a monopoly, the product or service offered is unique, with no real alternatives available. For example, if a pharmaceutical company holds the patent for a life-saving drug, there are no other options for patients who need it. This lack of substitutes gives the monopolist significant power over pricing and supply.

    2. Barriers to entry: These are obstacles that prevent new firms from entering the market and competing with the monopolist. Barriers can take various forms:

    • Legal barriers: Government-granted exclusive rights, like patents or licenses
    • Natural barriers: Control over essential resources or economies of scale
    • Strategic barriers: Actions taken by the monopolist to discourage competition

    For instance, a utility company might have a natural monopoly due to the high costs of infrastructure, making it impractical for competitors to enter the market.

    Now, let's compare monopolies to perfect competition, which sits at the opposite end of the market structure spectrum:

    In perfect competition:

    • Many small firms compete, each with minimal market share
    • Products are identical or very similar
    • There are no barriers to entry or exit
    • Firms are price takers, meaning they can't influence market prices

    Imagine a farmers' market where numerous vendors sell similar produce. No single seller can significantly impact prices, and customers can easily switch between vendors.

    In contrast, a monopoly:

    • Has a single dominant firm
    • Offers a unique product with no close substitutes
    • Has significant barriers to entry
    • Is a price maker, able to influence market prices

    Think of a company like Microsoft in its heyday, when Windows was the dominant operating system for personal computers. Users had limited alternatives, and the company could largely set its own prices.

    It's important to note that while monopolies can lead to higher prices and reduced consumer choice, they're not always harmful. In some cases, they can drive innovation or provide services more efficiently than a fragmented market could.

    Understanding monopolies and their features is crucial for grasping how different market structures function. Whether you're a student of economics, a business professional, or simply a curious consumer, recognizing the signs of a monopoly can help you better navigate the complex world of markets and competition.

    Types of Barriers to Entry

    Barriers to entry are obstacles that make it difficult for new firms to enter a market and compete with existing businesses. These barriers can be classified into three main types: natural barriers, ownership barriers, and legal barriers. Each type plays a crucial role in shaping market dynamics and competition. Let's explore these barriers in detail.

    Natural Barriers

    Natural barriers, also known as structural barriers, arise from the fundamental characteristics of an industry or market. These barriers are not artificially created but are inherent to the nature of the business. One of the most significant natural barriers is economies of scale.

    Economies of Scale

    Economies of scale occur when a company can reduce its average costs by increasing its production volume. This is often represented by the Long-Run Average Cost (LRAC) curve, which shows how average costs change as the scale of production increases. In industries with significant economies of scale, established firms have a cost advantage over new entrants, making it challenging for newcomers to compete effectively.

    For example, in the automobile industry, large manufacturers benefit from economies of scale in production, research and development, and marketing. A new entrant would need to produce at a similar scale to achieve comparable costs, which requires substantial initial investment.

    Other examples of natural barriers include:

    • High capital requirements: Industries like oil refining or semiconductor manufacturing require enormous upfront investments.
    • Network effects: In industries like social media, the value of a service increases with the number of users, making it difficult for new platforms to gain traction.
    • Technological complexity: Some industries require specialized knowledge or technology that is difficult to replicate or acquire.

    Ownership Barriers

    Ownership barriers arise when existing firms have control over essential resources or assets that are crucial for competing in the market. These barriers can be particularly challenging for new entrants to overcome.

    Key examples of ownership barriers include:

    • Control over scarce resources: For instance, a mining company that owns the rights to a rare mineral deposit.
    • Proprietary technology: Companies with patents or trade secrets that give them a significant competitive advantage.
    • Brand loyalty: Established brands with strong customer loyalty can make it difficult for new brands to gain market share.
    • Distribution networks: Existing firms may have exclusive agreements with distributors or retailers, limiting new entrants' access to customers.

    An example of an ownership barrier is the pharmaceutical industry, where companies hold patents on specific drugs. These patents prevent other firms from producing the same drug for a certain period, effectively creating a temporary monopoly.

    Legal Barriers

    Legal barriers are restrictions imposed by government regulations or laws that make it difficult for new firms to enter a market. These barriers are often put in place to protect consumers, ensure quality standards, or maintain market stability.

    Common types of legal barriers include:

    • Licenses and permits: Many industries require specific licenses or permits to operate, which can be costly or time-consuming to obtain.
    • Patents and copyrights: These protect intellectual property and can prevent new entrants from using certain technologies or designs.
    • Tariffs and quotas: In international trade, these can make it difficult for foreign companies to enter domestic markets.
    • Regulations: Environmental, safety, or quality regulations can increase the cost of entry for new firms.

    An example of a legal barrier is the banking industry, where new banks must obtain charters and comply with numerous regulations before they can start operations. This process can be lengthy and expensive, deterring potential new entrants.

    Understanding these three types of barriers to entry is crucial for both established firms and potential new entrants. For existing companies, recognizing and maintaining these barriers can help protect their market position. For new entrants, identifying and developing strategies to overcome these barriers is essential for successful market entry.

    It's important to note that while barriers to entry can protect established firms, they can also

    Legal Barriers to Entry in Detail

    Legal barriers to entry are government-imposed restrictions that create significant obstacles for new firms attempting to enter a market. These barriers often result in monopoly situations, limiting competition and potentially affecting consumer welfare. Four prominent types of legal barriers are public franchises, government licenses, patents, and copyrights.

    Public franchises are exclusive rights granted by the government to a private company to provide a specific service. For example, many cities grant exclusive franchises to cable television providers or utility companies. This creates a natural monopoly, as the franchisee becomes the sole legal provider of the service within a designated area. The New York City subway system, operated by the Metropolitan Transportation Authority, is a prime example of a public franchise monopoly.

    Government licenses act as another formidable legal barrier to entry. These are official permissions required to operate in certain industries or professions. The limited number of licenses issued can create artificial scarcity, leading to monopolistic or oligopolistic market structures. For instance, the taxi industry in many cities is regulated through a medallion system, where a fixed number of licenses (medallions) are issued. This system has historically limited competition and maintained high prices, although ride-sharing services have recently disrupted this model in many areas.

    Patents represent a crucial legal barrier in industries driven by innovation and technology. By granting inventors exclusive rights to their inventions for a specified period, patents create temporary monopolies. This exclusivity allows companies to recoup their research and development costs and profit from their innovations. The pharmaceutical industry heavily relies on patent protection, with companies like Pfizer and Merck enjoying monopoly status for their patented drugs until generic versions can legally enter the market.

    Copyrights, while similar to patents, protect original creative works such as literature, music, and software. They create legal barriers by preventing unauthorized reproduction or use of protected material. In the entertainment industry, copyrights enable companies like Disney to maintain exclusive control over their characters and content, effectively creating monopolies on specific intellectual properties. Microsoft's dominance in the operating system market, largely due to copyright protection of its Windows software, is another example of how copyrights can lead to market dominance.

    These legal barriers to entry serve various purposes, from protecting innovation and creativity to ensuring public safety and service quality. However, they also have the potential to create monopolies or near-monopoly situations, which can lead to higher prices, reduced innovation, and limited consumer choice. Policymakers must carefully balance the benefits of these protections against their potential negative impacts on market competition and consumer welfare.

    Monopoly Pricing Strategies

    Monopolies, as sole providers of a product or service in a market, have significant control over pricing. Two main pricing strategies employed by monopolies are single price monopoly and price discrimination. Understanding these strategies is crucial for both consumers and market analysts.

    A single price monopoly is a straightforward pricing strategy where the monopolist sets one uniform price for all consumers. This approach is simple to implement and manage. For example, a utility company might charge all residential customers the same rate per kilowatt-hour of electricity. While this strategy ensures consistency, it may not maximize the monopoly's profits as it doesn't account for varying consumer willingness to pay.

    On the other hand, price discrimination is a more complex strategy where the monopolist charges different prices to different consumers for the same product or service. This approach aims to capture more consumer surplus by tailoring prices based on factors such as demand elasticity, customer demographics, or purchase volume. Price discrimination can take various forms:

    First-degree price discrimination involves charging each consumer their maximum willingness to pay. While theoretically profitable, it's challenging to implement in practice due to the difficulty in determining individual preferences. Second-degree price discrimination offers different prices based on quantity purchased, such as bulk discounts. Third-degree price discrimination segments customers into groups and charges different prices accordingly, like student discounts for movie tickets.

    Examples of price discrimination are abundant in everyday life. Airlines often employ this strategy by charging different prices for the same flight based on factors like booking time, seat class, and customer loyalty status. Streaming services may offer tiered pricing plans with varying features. Software companies frequently use versioning, offering different product versions at different price points to cater to various customer segments.

    The implications of these pricing strategies are significant for both consumers and the market. Single price monopoly, while seemingly fair, may result in some consumers being priced out of the market entirely. It can also lead to deadweight loss, where potential transactions beneficial to both parties don't occur due to the fixed price.

    Price discrimination, when executed effectively, can increase market efficiency by allowing more consumers to access the product or service. It enables the monopolist to serve price-sensitive customers who might otherwise be excluded. However, it can also lead to perceived unfairness among consumers who pay higher prices. Additionally, the practice may incentivize monopolies to maintain their market power to continue discriminating prices effectively.

    For consumers, price discrimination can be both beneficial and detrimental. Some may enjoy lower prices or access to products they couldn't otherwise afford. Others might feel exploited if they consistently fall into higher-priced segments. The strategy can also lead to complex pricing structures, making it challenging for consumers to compare options and make informed decisions.

    From a market perspective, price discrimination can potentially increase overall economic efficiency by reducing deadweight loss. It allows the monopolist to capture more consumer surplus, which can theoretically lead to increased investment in product development or innovation. However, it may also exacerbate income inequality if higher-income consumers consistently receive preferential pricing.

    Regulators and policymakers often grapple with the implications of these pricing strategies. While price discrimination can enhance market efficiency, it may also raise concerns about fairness and consumer protection. Striking a balance between allowing firms to maximize profits and ensuring equitable access to goods and services remains a ongoing challenge in monopoly regulation.

    Impact of Monopolies on Market and Society

    Monopolies, characterized by a single company dominating a particular market, have significant implications for market efficiency, consumer welfare, and economic growth. These powerful entities shape the economic landscape in complex ways, presenting both potential benefits and drawbacks that warrant careful consideration.

    One of the primary concerns regarding monopolies is their impact on market efficiency. In a competitive market, multiple firms vie for consumers' attention, driving innovation and pushing prices down. However, monopolies lack this competitive pressure, potentially leading to reduced efficiency. Without rivals, monopolistic firms may have less incentive to innovate, improve product quality, or optimize their operations. This can result in stagnation and a misallocation of resources, hindering overall market efficiency.

    Consumer welfare is another crucial aspect affected by monopolies. On one hand, monopolies can leverage economies of scale to produce goods at lower costs, potentially passing savings on to consumers. They may also have the resources to invest in research and development, leading to innovative products. However, the absence of competition often results in higher prices, limited choices, and reduced quality for consumers. Monopolies can exploit their market power to maximize profits at the expense of consumer welfare, leading to a transfer of wealth from consumers to the monopolistic firm.

    The relationship between monopolies and economic growth is multifaceted. Large monopolistic firms can contribute significantly to a nation's GDP and may have the capacity to undertake large-scale projects that smaller companies cannot. Their size and resources can also facilitate international competitiveness. However, monopolies can stifle economic growth by creating barriers to entry for new firms, reducing entrepreneurship and innovation. The lack of competition can lead to complacency and inefficiency, potentially slowing overall economic progress.

    It's important to note that monopolies can achieve economies of scale, which is often cited as a potential benefit. By operating on a large scale, these firms can reduce per-unit costs, potentially leading to more efficient production. This efficiency could, in theory, result in lower prices for consumers. Additionally, monopolies may have the financial capacity to invest in extensive research and development, potentially driving technological advancements that benefit society as a whole.

    However, the drawbacks of monopolies often outweigh these potential benefits. The lack of competition is perhaps the most significant concern. Competition drives innovation, efficiency, and customer-focused improvements. Without it, monopolies may become complacent, focusing on maintaining their market position rather than improving their offerings. This can lead to a decline in product quality, higher prices, and reduced consumer choice.

    Monopolies can also exert undue influence on regulatory bodies and policymakers, potentially shaping legislation to protect their interests at the expense of broader economic welfare. This concentration of economic power can have far-reaching societal implications, affecting everything from labor markets to political processes.

    From an economic growth perspective, monopolies can impede the dynamic process of creative destruction that drives long-term progress. By preventing new entrants and stifling competition, they can slow the pace of innovation and technological advancement that are crucial for sustained economic growth.

    In conclusion, while monopolies may offer some benefits in terms of economies of scale and resource concentration, their overall impact on market efficiency, consumer welfare, and economic growth is often detrimental. The lack of competition typically leads to higher prices, reduced innovation, and potential abuse of market power. As such, policymakers and regulators must carefully balance the potential efficiencies of large-scale operations against the need for competitive markets that drive innovation, protect consumer interests, and foster sustainable economic growth.

    Regulation and Anti-Trust Laws

    Government regulation and anti-trust laws play a crucial role in controlling monopolies and maintaining fair competition in the marketplace. These measures are designed to prevent single entities from dominating entire industries, which can lead to reduced innovation, higher prices for consumers, and stifled economic growth. The implementation of anti-trust laws aims to promote a healthy, competitive business environment that benefits both consumers and the overall economy.

    One of the primary tools used to combat monopolies is the Sherman Antitrust Act of 1890, which prohibits activities that restrict interstate commerce and competition in the marketplace. This landmark legislation has been supplemented by additional laws, such as the Clayton Act and the Federal Trade Commission Act, which further strengthen the government's ability to regulate monopolistic practices.

    Throughout history, there have been several famous cases of monopoly breakups that have shaped the business landscape. One of the most notable examples is the 1984 breakup of AT&T, also known as "Ma Bell." The telecommunications giant was forced to split into seven regional companies, known as "Baby Bells," to promote competition in the phone service industry. This breakup led to increased innovation and lower prices for consumers in the long run.

    Another significant case was the United States v. Microsoft Corp. antitrust lawsuit in 1998. The government accused Microsoft of monopolistic practices in the personal computer market, particularly concerning its Internet Explorer web browser. While Microsoft wasn't ultimately broken up, the case resulted in increased scrutiny of the company's practices and paved the way for greater competition in the tech industry.

    The need for regulation in controlling monopolies is evident in several ways. Monopolies can lead to higher prices, reduced quality of goods and services, and a lack of incentive for innovation. By intervening, the government aims to protect consumers, foster competition, and maintain a level playing field for businesses of all sizes. Additionally, regulation can help prevent predatory pricing practices and other anti-competitive behaviors that can harm smaller companies and startups.

    However, it's important to consider potential drawbacks of government intervention in the market. Critics argue that excessive regulation can stifle innovation and economic growth by creating barriers to entry for new businesses. Some contend that large companies achieve their dominant positions through superior products or services and that breaking them up could potentially harm consumers by disrupting efficient operations.

    Furthermore, the global nature of modern business presents challenges in applying anti-trust laws across international borders. Companies may operate in multiple countries with different regulatory frameworks, making it difficult to enforce consistent anti-monopoly measures.

    In recent years, the debate surrounding monopolies has intensified with the rise of tech giants like Google, Amazon, and Facebook. These companies have faced increasing scrutiny over their market dominance and data practices, leading to calls for updated regulations that address the unique challenges posed by digital platforms.

    As the business landscape continues to evolve, finding the right balance between regulation and free-market principles remains a complex challenge. While government intervention through anti-trust laws is necessary to prevent the harmful effects of monopolies, it must be carefully implemented to avoid unintended consequences that could hinder economic growth and innovation.

    In conclusion, government regulation and anti-trust laws serve as essential tools in controlling monopolies and promoting fair competition. Famous cases like the AT&T breakup and the Microsoft antitrust suit demonstrate the impact of these measures on shaping industries. While the need for regulation is clear, policymakers must carefully consider both the benefits and potential drawbacks of market intervention to ensure a thriving, competitive economy that serves the interests of businesses and consumers alike.

    Conclusion

Monopolies are characterized by a single seller dominating the market, with high barriers to entry and no close substitutes. They often engage in price discrimination and output restriction to maximize profits. The economic impact of monopolies includes reduced consumer surplus, potential inefficiencies, and limited innovation. However, some argue that monopolies can drive technological advancements and achieve economies of scale. The introduction video provides a valuable foundation for grasping these complex concepts. To fully appreciate the nuances of monopolies, further study is recommended. Explore topics such as natural monopolies, government regulation, and antitrust policies. By delving deeper into monopoly market structures, you'll gain a more comprehensive understanding of their role in shaping economic landscapes and policy decisions. This knowledge is essential for anyone interested in economics, business, or public policy.

    Monopolies often engage in various strategies to maintain their market power, including price discrimination. This practice allows them to charge different prices to different consumers based on their willingness to pay, thereby maximizing their profits. Understanding these strategies is crucial for anyone studying economics or involved in policy-making.

    Monopoly Definitions Overview:

    Monopoly Definitions Overview: Definition of Monopoly

    • Single seller with no competition
    • Two key features to Monopoly
    • No Close Substitutes
    • Barrier to Entry

    Step 1: Introduction to Monopoly

    Welcome to this section where we will discuss the concept of Monopoly. A monopoly is a market structure characterized by a single seller who has exclusive control over a unique product. This seller faces no competition from other firms, making it distinct from other market structures like perfect competition, where multiple sellers offer identical products. In a monopoly, the single seller is the sole producer of a product that no other firm can replicate.

    Step 2: Unique Product

    In a monopoly, the product offered by the single seller is unique. This means that no other firms can produce a similar product. The uniqueness of the product is a crucial aspect of a monopoly, as it ensures that the single seller does not face competition from other firms producing similar goods. This uniqueness sets a monopoly apart from other market structures where multiple firms may produce similar or identical products.

    Step 3: No Close Substitutes

    One of the key features of a monopoly is the absence of close substitutes. If other firms could produce products that are close substitutes, the single seller would face competition, and the market would no longer be considered a monopoly. The lack of close substitutes ensures that the single seller remains the sole provider of the unique product, maintaining their monopoly status. This feature is essential for a monopoly to exist, as it prevents other firms from entering the market and offering similar products.

    Step 4: Barrier to Entry

    The second key feature of a monopoly is the presence of barriers to entry. These barriers are constraints that prevent or make it extremely difficult for new firms to enter the market. Barriers to entry can take various forms, such as high startup costs, regulatory hurdles, or control over essential resources. These barriers ensure that the single seller remains the only firm in the market, as new firms cannot easily enter and compete. The existence of barriers to entry is crucial for maintaining a monopoly, as it prevents potential competitors from challenging the single seller's dominance.

    Step 5: Conclusion

    In summary, a monopoly is a market structure characterized by a single seller with no competition, offering a unique product with no close substitutes. The presence of barriers to entry ensures that new firms cannot easily enter the market and compete with the single seller. These features distinguish a monopoly from other market structures and highlight the unique nature of monopolistic markets. Understanding these key aspects of a monopoly is essential for comprehending how monopolies operate and maintain their market dominance.

    FAQs

    1. Are patents and copyrights a barrier to entry?

      Yes, patents and copyrights are considered legal barriers to entry. They grant exclusive rights to the creators or inventors, preventing others from using, producing, or selling the protected intellectual property without permission. This exclusivity can make it difficult for new firms to enter a market where key technologies or creative works are protected.

    2. Is a patent a natural barrier to entry?

      No, a patent is not a natural barrier to entry. It is a legal barrier created by government regulations to protect intellectual property. Natural barriers arise from market conditions or industry characteristics, such as economies of scale or high capital requirements, rather than legal protections.

    3. What is an example of a patent barrier to entry?

      A classic example of a patent barrier to entry is in the pharmaceutical industry. When a company develops a new drug, it can obtain a patent that prevents other companies from producing or selling that drug for a set period, typically 20 years. This gives the patent holder a temporary monopoly, making it difficult for new firms to enter the market with the same product.

    4. Is a copyright an example of a legal barrier to entry?

      Yes, copyright is an example of a legal barrier to entry. It protects original creative works such as books, music, software, and artistic creations. Copyright prevents others from reproducing, distributing, or creating derivative works without permission, which can limit new entrants in industries heavily reliant on copyrighted material.

    5. How long do patents and copyrights typically last?

      Patent duration varies by type but generally lasts 20 years from the filing date for utility patents in the United States. Copyrights have a much longer duration, typically lasting for the author's lifetime plus an additional 70 years after their death. These extended periods of protection can create significant long-term barriers for potential market entrants.

    Prerequisite Topics

    Understanding monopoly definitions is crucial in the study of microeconomics, but to fully grasp this concept, it's essential to have a solid foundation in several prerequisite topics. These topics provide the necessary context and comparative frameworks that make monopoly concepts more comprehensible and meaningful.

    One of the most important prerequisite topics is perfect competition. This economic model serves as a stark contrast to monopolies, helping students understand the unique characteristics of monopolistic markets. By studying perfect competition, learners can better appreciate how monopolies deviate from this idealized market structure, particularly in terms of price-setting power and market entry barriers.

    Another critical prerequisite is the concept of consumer and producer surplus. This topic is fundamental to understanding the welfare effects of monopolies. In a monopolistic market, the distribution of surplus is significantly different from that in competitive markets. Grasping these concepts allows students to analyze the efficiency losses associated with monopolies and evaluate their impact on overall economic welfare.

    Additionally, familiarity with price discrimination is essential when studying monopolies. Monopolists often engage in price discrimination to maximize their profits, and understanding this practice is crucial for comprehending monopoly behavior and its effects on different consumer groups.

    These prerequisite topics collectively provide a comprehensive framework for analyzing monopolies. Perfect competition offers a baseline for comparison, consumer and producer surplus concepts enable welfare analysis, and price discrimination insights shed light on monopolistic pricing strategies. By mastering these foundational concepts, students can more effectively navigate the complexities of monopoly definitions and their implications in real-world markets.

    Moreover, these prerequisites are interconnected, forming a web of knowledge that enhances overall economic understanding. For instance, the ability to compare perfect competition with monopoly structures allows for a deeper appreciation of how market power affects consumer and producer surplus. Similarly, understanding surplus concepts is crucial for evaluating the efficiency and equity implications of price discrimination practices in monopolistic markets.

    In conclusion, a thorough grasp of these prerequisite topics is not just beneficial but essential for anyone seeking to master monopoly definitions. They provide the necessary context, comparative frameworks, and analytical tools that make the study of monopolies more accessible and meaningful. By building this foundational knowledge, students can develop a more nuanced and comprehensive understanding of monopolistic market structures and their significant role in the broader economic landscape.

    Definition of Monopoly

    Monopoly: a market with a single seller who sells a unique product that no other firms can produce.

    A Monopoly is a market which has the following two features:

    1. No Close Substitute: If one or more firms can produce a close substitute, then the single seller will face competition from the producers of the substitute.

    2. Barrier to Entry: are constraints that prevent or makes it extremely difficult for new firms to enter the market.

    Barriers to Entry:

    There are 3 types of barriers to entry:

    1. Natural Barrier to Entry: Economies of Scale causes one firm to be able to supply the entire market at the lowest possible cost. A natural barrier to entry creates natural monopoly.

      Monopoly natural barrier to entry
      Note: The firm realizes from the LRAC that the more outputs they produce, the lower the cost for each unit. Hence, they supply the entire market.

    2. Ownership Barrier to Entry:occurs when one firm owns a huge portion of a resource that is used to produce the good.

    3. Legal Barrier to Entry:a barrier where competition and entry are restricted by the granting of:

      1. Public franchise: exclusive right granted to a firm to supply a good or service
      2. Government license: controls entry into specific jobs, or industries
      3. Patent: exclusive right given to the inventor of a good
      4. Copyright: exclusive right given to an author or composer.

    Methods to Setting Prices to Monopoly:

    In a monopoly, the firm can set its own prices. However, they also know that the amount of quantity produces changes the market price. There are two methods to setting prices to buyers:

    1. Single-Price Monopoly: the firm sells each unit of output for the same price to all buyers.

    2. Price Discrimination: the firms sell their unit of output for difference prices to different buyers.

      Note: When firms price discriminates, their motive is to charge the highest possible price for each unit sold to gain the most profit.
