Supply (economics) in the context of "Shortage"

A price is the (usually not negative) quantity of payment or compensation expected, required, or given by one party to another in return for goods or services. In some situations, especially when the product is a service rather than a physical good, the price for the service may be called something else such as "rent" or "tuition". Prices are influenced by production costs, supply of the desired product, and demand for the product. A price may be determined by a monopolist or may be imposed on the firm by market conditions.

Price can be quoted in currency, quantities of goods or vouchers.

A supply shock is an event that suddenly increases or decreases the supply of a commodity or service, or of commodities and services in general. This sudden change affects the equilibrium price of the good or service or the economy's general price level.

In the short run, an economy-wide negative supply shock will shift the aggregate supply curve leftward, decreasing the output and increasing the price level. For example, the imposition of an embargo on trade in oil would cause an adverse supply shock, since oil is a key factor of production for a wide variety of goods. A supply shock can cause stagflation due to a combination of rising prices and falling output. The 1973 Oil Crisis is often used as the exemplar case of a supply shock, when OPEC restrictions on production and sale of petroleum resulted in fuel shortages throughout the developed world.

In microeconomics, a monopoly price is set by a monopoly. A monopoly occurs when a firm lacks any viable competition and is the sole producer of the industry's product. Because a monopoly faces no competition, it has absolute market power and can set a price above the firm's marginal cost.

The monopoly ensures a monopoly price exists when it establishes the quantity of the product. As the sole supplier of the product within the market, its sales establish the entire industry's supply within the market, and the monopoly's production and sales decisions can establish a single price for the industry without any influence from competing firms. The monopoly always considers the demand for its product as it considers what price is appropriate, such that it chooses a production supply and price combination that ensures a maximum economic profit, which is determined by ensuring that the marginal cost (determined by the firm's technical limitations that form its cost structure) is the same as the marginal revenue (MR) (as determined by the impact a change in the price of the product will impact the quantity demanded) at the quantity it decides to sell. The marginal revenue is solely determined by the demand for the product within the industry and is the change in revenue that will occur by lowering the price just enough to ensure a single additional unit is sold. The marginal revenue is positive, but it is lower than its associated price because lowering the price will increase the demand for its product and increase the firm's sales revenue, and lower the price paid by those who are willing to buy the product at the higher price, which ensures a lower sales revenue on the product sales than those willing to pay the higher price.

In economics, induced demand – related to latent demand and generated demand – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that the quantity demanded subsequently increases. This is consistent with the economic model of supply and demand.

In transportation planning, induced demand, also called "induced traffic" or consumption of road capacity, has become important in the debate over the expansion of transportation systems, and is often used as an argument against increasing roadway traffic capacity as a cure for congestion. Induced traffic may be a contributing factor to urban sprawl. City planner Jeff Speck has called induced demand "the great intellectual black hole in city planning, the one professional certainty that every thoughtful person seems to acknowledge, yet almost no one is willing to act upon."

Georgism, in modern times also called Geoism, and known historically as the single tax movement, is an economic ideology holding that persons should own the value that they produce themselves, while the economic rent derived from land—including from all natural resources, the commons, and urban locations—should belong equally to all members of society. Developed from the writings of American economist and social reformer Henry George, the Georgist paradigm seeks solutions to social and ecological problems based on principles of land rights and public finance that attempt to integrate economic efficiency with social justice.

Georgism is concerned with the distribution of economic rent caused by land ownership, natural monopolies, pollution rights, and control of the commons, including title of ownership for natural resources and other contrived privileges (e.g., intellectual property). Any natural resource that is inherently limited in supply can generate economic rent, but the classical and most significant example of land monopoly involves the extraction of common ground rent from valuable urban locations. Georgists argue that taxing economic rent is efficient, fair, and equitable. The main Georgist policy recommendation is a land value tax (LVT), the revenues from which can be used to reduce or eliminate existing taxes (such as on income, trade, or purchases) that are posited to be unfair and inefficient. Some Georgists also advocate the return of surplus public revenue to the people by means of a basic income or citizen's dividend.

A drug cartel is a criminal organization composed of independent drug lords who collude with each other in order to improve their profits and dominate the illegal drug trade. Drug cartels form with the purpose of controlling the supply of the illegal drug trade and maintaining prices at a high level. The formations of drug cartels are common in Latin American countries. Rivalries between multiple drug cartels cause them to wage turf wars against each other. Drug cartels often transport both drugs and narcotics, and most often the term "Narcotics cartel" is not used to describe an organization that transports the latter legally defined set of illegal substances, such as marijuana.
