Informal economyAn informal economy (informal sector or grey economy) is the part of any economy that is neither taxed nor monitored by any form of government. Although the informal sector makes up a significant portion of the economies in developing countries, it is sometimes stigmatized as troublesome and unmanageable. However, the informal sector provides critical economic opportunities for the poor and has been expanding rapidly since the 1960s. Integrating the informal economy into the formal sector is an important policy challenge.
EconomyAn economy is an area of the production, distribution and trade, as well as consumption of goods and services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of scarce resources. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors.
Phillips curveThe Phillips curve is an economic model, named after William Phillips, that predicts a correlation between reduction in unemployment and increased rates of wage rises within an economy. While Phillips himself did not state a linked relationship between employment and inflation, this was a trivial deduction from his statistical findings. Paul Samuelson and Robert Solow made the connection explicit and subsequently Milton Friedman and Edmund Phelps put the theoretical structure in place.
Sterling areaThe sterling area (or sterling bloc, legally scheduled territories) was a group of countries that either pegged their currencies to sterling, or actually used sterling as their own currency. The area began to appear informally during the early 1930s, after sterling had left the gold standard in 1931, with the result that a number of currencies of countries that historically had performed a large amount of their trade in sterling were pegged to sterling instead of to gold.
Aggregate demandIn macroeconomics, aggregate demand (AD) or domestic final demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amount of goods and services that will be purchased at all possible price levels. Consumer spending, investment, corporate and government expenditure, and net exports make up the aggregate demand.
Economies of scopeEconomies of scope are "efficiencies formed by variety, not volume" (the latter concept is "economies of scale"). In economics, "economies" is synonymous with cost savings and "scope" is synonymous with broadening production/services through diversified products. Economies of scope is an economic theory stating that average total cost of production decrease as a result of increasing the number of different goods produced. For example, a gas station that sells gasoline can sell soda, milk, baked goods, etc.
Private currencyA private currency is a currency issued by a private entity, be it an individual, a commercial business, a nonprofit or decentralized common enterprise. It is often contrasted with fiat currency issued by governments or central banks. In many countries, the issuance of private paper currencies and/or the minting of metal coins intended to be used as currency may even be a criminal act such as in the United States (18 U.S. Code § 486). Digital cryptocurrency is sometimes treated as an asset instead of a currency.
Virtual economyA virtual economy (or sometimes synthetic economy) is an emergent economy existing in a virtual world, usually exchanging virtual goods in the context of an online game, particularly in massively multiplayer online games (MMOs). People enter these virtual economies for recreation and entertainment rather than necessity, which means that virtual economies lack the aspects of a real economy that are not considered to be "fun" (for instance, avatars in a virtual economy often do not need to buy food in order to survive, and usually do not have any biological needs at all).
Welfare capitalismWelfare capitalism is capitalism that includes social welfare policies and/or the practice of businesses providing welfare services to their employees. Welfare capitalism in this second sense, or industrial paternalism, was centered on industries that employed skilled labor and peaked in the mid-20th century. Today, welfare capitalism is most often associated with the models of capitalism found in Central Mainland and Northern Europe, such as the Nordic model and social market economy (also known as Rhine capitalism and social capitalism).
Developing countryA developing country is a sovereign state with a less developed industrial base and a lower Human Development Index (HDI) relative to other countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but refers only to the economy of the countries.
