Public goods in economics are goods or services that are non-excludable and non-rivalrous. This means that once provided, individuals cannot be excluded from using the good or service, and one person's use of the good does not diminish its availability for others. Examples of public goods include national defense, clean air, and street lighting. Because public goods are not efficiently provided by the market due to the free-rider problem, they are often provided by the government. **

In the field of law and economics, complementary goods are products or services that are typically consumed together, such as a printer and ink cartridges. When the price of one complementary good increases, the demand for the other complementary good may decrease. On the other hand, substitute goods are products or services that can be used in place of each other, such as butter and margarine. If the price of one substitute good increases, consumers may switch to the other substitute good to save money. **

In economics, goods are categorized into two main types: 1) tangible goods, which are physical products that can be touched and seen, such as cars, clothes, and food; and 2) intangible goods, which are services or experiences that cannot be physically touched, such as healthcare, education, and entertainment. Tangible goods are typically produced and consumed, while intangible goods are often provided by individuals or businesses to meet specific needs or wants. Both types of goods play a crucial role in the economy by satisfying consumer demands and driving economic growth. **
