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.

Sir Edgar Speyer, 1st Baronet (7 September 1862 – 16 February 1932) was an American-born financier and philanthropist. He became a British subject in 1892 and was chairman of Speyer Brothers, the British branch of the Speyer family's international finance house, and a partner in the German and American branches. He was chairman of the Underground Electric Railways Company of London (UERL, forerunner of the London Underground) from 1906 to 1915, a period during which the company opened three underground railway lines, electrified a fourth and took over two more.

Project management is the process and activity of planning, organizing, motivating, and controlling resources, procedures and protocols to achieve specific goals in scientific or daily problems. A project is a temporary endeavor designed to produce a unique product, service or result with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables), undertaken to meet unique goals and objectives, typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with business as usual (or operations), which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, the management of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies.)

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.

Selected quote

"Man cannot create material things. In the mental and moral world indeed he may produce new ideas; but when he is said to produce material things, he really only produces utilities; or in other words, his efforts and sacrifices result in changing the form or arrangement of matter to adapt it better for the satisfaction of wants. All that he can do in the physical world is either to readjust matter so as to make it more useful, as when he makes a log of wood into a table; or to put it in the way of being made more useful by nature, as when he puts seed where the forces of nature will make it burst out into life.

It is sometimes said that traders do not produce: that while the cabinet-maker produces furniture, the furniture-dealer merely sells what is already produced. But there is no scientific foundation for this distinction. They both produce utilities, and neither of them can do more: the furniture-dealer moves and rearranges matter so as to make it more serviceable than it was before, and the carpenter does nothing more. The sailor or the railway-man who carries coal above ground produces it, just as much as the miner who carries it underground; the dealer in fish helps to move on fish from where it is of comparatively little use to where it is of greater use, and the fisherman does no more. It is true that there are often more traders than are necessary; and that, whenever that is the case, there is a waste. But there is also waste if there are two men to a plough which can be well worked by one man; in both cases all those who are at work produce, though they may produce but little. Some writers have revived the mediæval attacks on trade on the ground that it does not produce. But they have not aimed at the right mark. They should have attacked the imperfect organization of trade, particularly of retail trade."

Alfred Marshall, Principles of Economics, 1890
