Whether you are a student looking to supplement your economics knowledge or a curious individual interested in understanding basic economic concepts, this lesson will provide you with a comprehensive understanding of important microeconomic terms. So, let's dive in!
Introduction:
引言：
Microeconomics is the study of individual economic units and their interactions in specific markets. By understanding key microeconomic concepts, we can better comprehend market behavior, consumer choices, and the impact of government policies on the economy. This lesson aims to provide clear and concise explanations of essential microeconomic terms, accompanied by bilingual examples to enhance understanding.
Section 1: Supply and Demand
第一节：供求关系
1. Supply
供给
Supply refers to the quantity of a good or service that producers are willing and able to offer for sale at different prices during a specific time
period. It is determined by factors such as production costs, technological advancements, and resource availability. The law of supply states that as prices rise, the quantity supplied increases, and vice versa, assuming other factors remain constant.
Example:
举例：
If the price of oranges increases, orange growers will be motivated to increase their supply to take advantage of the higher profits.
2. Demand
需求
Demand represents the quantity of a good or service that consumers are willing and able to purchase at various prices during a given time period. It depends on factors such as the price of the product, consumer preferences, income levels, and the availability of substitutes. According to the law of demand, price and quantity demanded have an inverse relationship, assuming other factors remain constant.
Example:
举例：
When the price of smartphones decreases, the demand for smartphones increases as more consumers can afford to purchase them.
3. Equilibrium
均衡
Equilibrium refers to the point at which quantity demanded equals quantity supplied in a given market. At this point, there is no pressure for prices or quantities to change. The market reaches equilibrium when supply and demand intersect.
Example:
举例：
In a perfectly competitive market, the equilibrium price and quantity of a product are determined solely by market forces.
Section 2: Market Structures
第二节：市场结构
1. Perfect Competition
完全竞争
Perfect competition is a market structure characterized by a large number of buyers and sellers, homogeneous products, perfect information, freedom of entry and exit, and no individual market participant can influence the market price. In a perfectly competitive market, all firms are price takers.
Example:
举例：
The agricultural market, with many farmers selling identical crops, is often considered an example of perfect competition.
2. Monopoly
垄断
A monopoly exists when a single firm is the sole provider of a product or service in the market, giving it significant market power. Monopolies often emerge due to barriers to entry, such as exclusive ownership of essential resources or government regulations.
Example:
举例：
The pharmaceutical company XYZ has a monopoly on a specific drug, allowing them to dictate the price and control the supply.
3. Monopolistic Competition
垄断竞争
Monopolistic competition characterizes a market structure in which numerous firms sell differentiated products that are close substitutes. Each firm has some control over price by using advertising, branding, or product differentiation. However, they still face competition from other firms in the market.
Example:
举例：
The fast-food industry, with various restaurants offering slightly different menus and experiences, is an example of monopolistic competition.
Section 3: Market Failures
第三节：市场失灵
1. Externalities
外部性
Externalities are costs or benefits that result from the production or consumption of a good or service, affecting individuals or entities not directly involved in the transaction. Externalities can be positive (beneficial) or negative (harmful) and may lead to market failure due to the misalignment between private and social costs or benefits.
Example:
举例：
Air pollution caused by factory emissions is a negative externality that imposes health and environmental costs on society.
2. Public Goods
公共物品
Public goods are non-excludable and non-rivalrous goods or services. Non-excludable means that individuals cannot be excluded from enjoying the benefits of the good or service, and non-rivalrous means that one person consuming the good does not diminish its availability to others. Public goods are often provided by the government due to their difficulty to be efficiently provided by the market alone.
Example:
举例：
Street lighting is a public good because once installed, it benefits all individuals in a community, and one person's use does not impede others' ability to benefit from it.
