Inferior goodIn economics, inferior goods are those goods the demand for which falls with increase in income of the consumer. So, there is an inverse relationship between income of the consumer and the demand for inferior goods. There are many examples of inferior goods, including subcompact economy cars, public transit, payday lending, second-hand clothes, and inexpensive food.
Luxury goodsIn economics, a luxury good (or upmarket good) is a product or item or service for which demand increases more than what is proportional as income rises, so that expenditures on the good become a more significant proportion of overall spending. Luxury goods are in contrast to necessity goods, where demand increases proportionally less than income.Marginal utilityIn mainstream economics, marginal utility refers to the change in utility (pleasure or satisfaction resulting from the consumption) of one unit of a good or service. Marginal utility can be positive, negative, or zero. Negative marginal utility implies that every consumed additional unit of a commodity causes more harm than good, leading to a decrease in overall utility.
Consumer behaviourStudy of consumption of goods and servicesThe Royal Saint-Hubert Galleries shopping arcade in Brussels, Belgium.

EconomicsEconomics () is a social science that studies the production, distribution, and consumption of goods and services. Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyses what is viewed as the basic elements of economies, including individual agents and markets, their interactions, and the outcomes of those interactions. Individual agents may include households, firms, buyers, and sellers.
Rivalry (economics)In economics, a good is said to be rivalrous or a rival if its consumption by one consumer prevents simultaneous consumption by other consumers, or if consumption by one party reduces the ability of another party to consume it. A good is considered non-rivalrous or non-rival if, for any level of production, the cost of providing it to a marginal (additional) individual is zero. A good is anti-rivalrous and inclusive if each person benefits more when other people consume it.

Public goodAids to navigation such as lighthouses are often used as an example of a public good, as they benefit all maritime users, but no one can be excluded from using them.In economics, a public good (also referred to as a social good or collective good) is a commodity, product or service that is both non-excludable and non-rivalrous and which is typically provided by a government and paid for through taxation.
ExcludabilityIn economics, excludability is the degree to which a good, service or resource can be limited to only paying customers, or conversely, the degree to which a supplier, producer or other managing body (e.g. a government) can prevent consumption of a good. In economics, a good, service or resource is broadly assigned two fundamental characteristics; a degree of excludability and a degree of rivalry.*As an Amazon Associate I earn from qualifying purchases.
