Commodity in the context of "Derivative (finance)"

Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment.

Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international community has created policy focused on sustainable infrastructure through the Sustainable Development Goals, especially Sustainable Development Goal 8 "Industry, Innovation and Infrastructure".

A plantation economy is an economy based on agricultural mass production, usually of a few commodity crops, grown on large farms worked by laborers or slaves. The properties are called plantations. Plantation economies rely on the export of cash crops as a source of income. Prominent crops included cotton, rubber, sugar cane, tobacco, figs, rice, kapok, sisal, Red Sandalwood, and species in the genus Indigofera, used to produce indigo dye.

The longer a crop's harvest period, the more efficient plantations become. Economies of scale are also achieved when the distance to market is long. Plantation crops usually need processing immediately after harvesting. Sugarcane, tea, sisal, and palm oil are most suited to plantations, while coconuts, rubber, and cotton are suitable to a lesser extent.

In economics, scarcity refers to the basic fact of life that there exists only a finite amount of human and nonhuman resources which the best technical knowledge is capable of using to produce only limited maximum amounts of each economic good. If the conditions of scarcity did not exist and an "infinite amount of every good could be produced or human wants fully satisfied ... there would be no economic goods, i.e. goods that are relatively scarce..." Scarcity is the limited availability of a commodity, which may be in demand in the market or by the commons. Scarcity also includes an individual's lack of resources to buy commodities. The opposite of scarcity is abundance. Scarcity plays a key role in economic theory, and it is essential for a "proper definition of economics itself".

British economist Lionel Robbins is famous for his definition of economics which uses scarcity: "Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses." Economic theory views absolute and relative scarcity as distinct concepts and is "quick in emphasizing that it is relative scarcity that defines economics." Current economic theory is derived in large part from the concept of relative scarcity which "states that goods are scarce because there are not enough resources to produce all the goods that people want to consume".

A store of value is any commodity or asset that would normally retain purchasing power into the future and is the function of the asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved.

The most common store of value in modern times has been money, currency, or a commodity like a precious metal or financial capital. The point of any store of value is risk management due to a stable demand for the underlying asset.

Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves (intrinsic value) as well as their value in buying goods.This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, for which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.

Examples of commodities that have been used as media of exchange include precious metals and stones, grain, animal parts (such as beaver pelts), tobacco, fuel, and others. Sometimes several types of commodity money were used together, with fixed relative values, in various commodity valuation or price system economies.

Fiat money is a type of government-issued currency, authorized by government regulation to be legal tender. Typically, fiat currency is not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Since the end of the Bretton Woods system in 1976 by the Jamaica Accords, all the major currencies in the world are fiat money.

Fiat money generally does not have intrinsic value and does not have use value. It has value only because the individuals who use it (as a unit of account or, in the case of currency, a medium of exchange) agree on its value. They trust that it will be accepted by merchants and other people as a means of payment for liabilities.

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.

Hoarding in economics refers to the concept of purchasing and storing a large amount of a particular product, creating scarcity of that product, and ultimately driving the price of that product up. Commonly hoarded products include assets such as money, gold and public securities, as well as vital goods such as fuel and medicine. Consumers are primarily hoarding resources so that they can maintain their current consumption rate in the event of a shortage (real or perceived). Hoarding resources can prevent or slow products or commodities from traveling through the economy. Subsequently, this may cause the product or commodity to become scarce, causing the value of the resource to rise.

A common intention of economic hoarding is to generate a profit by selling the product once the price has increased. Hence, economic speculators tend to hoard products that are inelastic in price so that when the price of the product does increase, the demand for that product is maintained. Unlike investing, hoarded goods are excluded from an economy's flow of money and purchasing goods for hoarding generally occurs in markets operating under a non-competitive structure. The practice of hoarding can have varied effects in the economy and is legal in most cases, however price controls and other regulatory laws are often enforced to prevent negative market implications. Under Islamic jurisprudence, intentional acts of economic hoarding are regarded as highly sinful and unlawful.

In economics, a duty is a target-specific form of tax levied by a state or other political entity. It is often associated with customs, in which context they are also known as tariffs or dues. The term is often used to describe a tax on certain items purchased abroad.

A duty is levied on specific commodities, financial transactions, estates, etc. rather than being a direct imposition on individuals or corporations such income or property taxes. Examples include customs duty, excise duty, stamp duty, estate duty, and gift duty.
