Keywords

💡Duopoly

A duopoly refers to a market structure where two firms dominate the market, controlling a high market share and having significant influence over the price and quantity of a particular product or service. In the context of the video, duopolies are discussed as a form of market concentration that can lead to limited competition and higher prices for consumers. Examples from the script include Coca-Cola and PepsiCo in the soft drink industry, and Google and Facebook in online advertising.

💡Market Share

Market share is the portion of the total available market that a company or a product captures. It is an indicator of a company's size and influence within its industry. The video explains that in a duopoly, the two dominant firms control a significant share of the market, leaving little room for smaller competitors, which is exemplified by the dominance of Coca-Cola and PepsiCo in the soft drink market.

💡Influence Over Price and Quantity

In a duopoly, the dominant firms have the power to influence the price and quantity of products or services in the market. This is due to their significant market share and control over supply. The video discusses how this influence can result in higher prices for consumers and less choice due to the limited competition.

💡Limited Competition

Limited competition refers to a situation where there are few players in the market, which can lead to a lack of alternatives for consumers and potentially higher prices. The video highlights that duopolies often result in limited competition, as seen with the dominance of Google and Facebook in online advertising, which can stifle innovation and consumer choice.

💡Higher Prices for Consumers

Higher prices for consumers are a potential consequence of a duopoly, where the lack of competition can lead to the dominant firms setting higher prices for their products or services. The video script mentions that due to the limited competition in a duopoly, prices may be higher than in a more competitive market.

💡Stifle Innovation

Stifling innovation means to suppress or discourage the development of new ideas, products, or services. In the context of the video, duopolies may stifle innovation because the dominant firms have less incentive to innovate when they face little competition, and new entrants may find it difficult to break into the market.

💡Consumer Choice

Consumer choice refers to the range of options available to consumers when making a purchase decision. The video explains that duopolies can limit consumer choice by reducing the number of firms in the market, which in turn reduces the variety of products and services available to consumers.

💡Antitrust Laws

Antitrust laws are legal regulations designed to promote fair competition and prevent the abuse of market power by dominant firms. The video discusses how governments use antitrust laws, such as the Sherman Antitrust Act in the USA, to combat the negative effects of monopolies and duopolies by preventing firms from acquiring too much market power.

💡Monopolistic Practices

Monopolistic practices refer to actions taken by a firm or a group of firms to dominate a market in a way that excludes competition. The video mentions that antitrust laws aim to prevent such practices, which can lead to higher prices, reduced innovation, and limited consumer choice.

💡Telecommunication Industry

The telecommunication industry is an example of a market where a duopoly can occur, as mentioned in the video. Companies in this industry provide services related to communication, such as mobile phones and internet services. The video script uses AT&T and another unnamed company as an example of how a duopoly can dominate the telecommunication market in the USA.

💡Online Advertising Industry

The online advertising industry is another context where a duopoly is discussed in the video. This industry involves the buying and selling of advertising space on digital platforms. Google and Facebook are cited as the dominant players in this industry, with Google leading in search advertising and Facebook in social media advertising.
