In the social sciences, economics is the study of human choice behavior and the methodology used to make associated investment and production decisions; in particular, though not limited to, how those choices and decisions determine the allocation of scarce resources and their effect on production, distribution, and consumption. The word "economics" is from the Greek words οἶκος [oikos], meaning "family, household, estate", and νόμος [nomos], or "custom, law", and hence literally means "household management" or "management of the state". An economist is a person using economic concepts and data in the course of employment, or someone who has earned a university degree in the subject. Economics undergraduate courses always cover at least the two main branches:

  • Microeconomics studies the behavior of individual households and firms in making decisions on the allocation of limited resources. Microeconomics applies to markets where goods or services are bought and sold. It examines how decisions and behaviors affect the supply and demand for goods and services, which determines prices, and how prices, in turn, determine the quantity supplied and quantity demanded of goods and services.
  • Macroeconomics deals with the performance, structure, behavior, and decision-making of an economy as a whole, rather than individual markets. This includes national, regional, and global economies.

However, there are also other sub-fields of economics.

In economics, economic systems is the study and analysis of organizing production, distribution, consumption and investment and the study of optimal resource allocation and institutional design. Traditionally the study of economic systems was based on a dichotomy between market economies and planned economies, but contemporary studies compare and contrast a number of different variables, such as ownership structure (Public, Private or Collective), economic coordination (planning, markets or mixed), management structure (Hierarchy versus adhocracy), the incentive system, and the level of centralization in decision-making. An economy can be analyzed in terms of its economic sectors, the classic breakdown being into primary, secondary and tertiary. A business, also known as an enterprise or a firm, is an organization involved in the trade of goods, services, or both to consumers. Businesses are prevalent in capitalist economies, where most of them are privately owned and provide goods and services to customers in exchange of other goods, services, or money. Businesses may also be not-for-profit or state-owned. Management in business and organizations is the function that coordinates the efforts of people to accomplish goals and objectives using available resources efficiently and effectively. Management comprises planning, organizing, staffing, leading or directing, and controlling an organization or initiative to accomplish a goal. Management is also an academic discipline, and is traditionally taught at business schools. Economic policy refers to the actions that governments take in the economic field. It covers the systems for setting interest rates and government budget as well as the labor market regulations, national ownership, trade policy, monetary policy, fiscal policy, regulatory policy, anti-trust policy and industrial policy. In economics, sustainable development refers to development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

At Old Street, street markings and a sign (inset) with the white-on-red C alert drivers to the charge. The sign displays the original operating hours for the scheme.

The London congestion charge is a fee charged on most motor vehicles operating within the Congestion Charge Zone (CCZ) in central London between 07:00 and 18:00 (Monday-Friday only). The charge, which was introduced on 17 February 2003, remains one of the largest congestion zones in the world despite the cancellation of the Western Extension which operated between February 2007 and January 2011. The charge aims to reduce congestion, and to raise investment funds for London's transport system. The standard charge is £10 for each day, for each non-exempt vehicle that travels within the zone with a penalty of between £60 and £187 levied for non-payment. Enforcement is primarily based on automatic number plate recognition (ANPR). Transport for London (TfL) is responsible for the charge which has been operated by IBM since 1 November 2009.

The United States of America is the world's largest single national economy. The United States' nominal GDP was estimated to be $17.295 trillion as of Q2 2014, approximately a quarter of nominal global GDP. Its GDP at purchasing power parity is also the largest of any single country in the world, approximately a fifth of the global total. The U.S. dollar is the currency most used in international transactions and is the world's foremost reserve currency. Several countries use it as their official currency, and in many others it is the de facto currency. Its six largest trading partners are Canada, China, Mexico, Japan, Germany, and Italy.

The differential rate system of piece-work consists briefly, in offering two different rates for the same job, a high price per piece in case the work is finished in the shortest possible time and in perfect condition, and a low price if it takes a longer time to do the job, of if there are any imperfections in the work. (The high rate should be such that the workman can earn more per day than is usually paid in similar establishments.) This is directly the opposite of the ordinary plan of piece-work in which the wages of the workmen are reduced when they increase their productivity.

Frederick Winslow Taylor, Piece-Rate System, 1896

  • ...the term petrodollars was coined by Ibrahim Oweiss to describe dollars that did not circulate inside the United States, and therefore were not part of the normal money supply, and instead were received by petroleum exporting countries (OPEC) in exchange for oil?
