Information About

Economic




An economy is the system of human activities related to the production, distribution, exchange, and consumption of goods and services in a particular geographic region.

The composition of a given economy is inseparable from Technological Evolution , civilization's History and Social Organization , as well as from Earth's Geography and Ecology , e.g. ecoregions which represent different Agricultural and Resource Extraction opportunities, among other factors.

Economy refers also to the measure of how a country or region is progressing in terms of Product .


ETYMOLOGY

The word "economy" can be traced back to the Greek word ''oikonomos'', "one who manages a household," derived from ''oikos'', "house," and ''nemein'', "to manage." From ''oikonomos'' was derived ''oikonom'', which had not only the sense "management of a houseold or family" but also senses such as "thrift," "direction," "administration," "arrangement," and "public revenue of a state." The first recorded sense of the word "economy", found in a work possibly composed in 1440, is "the management of economic affairs," in this case, of a monastery. Economy is later recorded in other senses shared by ''oikonomi'' in Greek, including "thrift" and "administration." What is probably the most frequently used current sense, "the economic system of a country or an area," seems not to have developed until the 19th or 20th century.


THE RANGE OF ACTIVITIES INVOLVED



SECTORS

See Also: Three-sector hypothesis


See Also: List of recognized economic sectors


The economy includes several sectors (also called Industries ), that evolved in successive phases.




In modern economies, there are three main sectors of economic activity:
  • Primary sector: Involves the extraction and production of raw materials, such as corn, coal, wood and iron. (A coal miner and a fisherman would be workers in the primary sector.)

  • Secondary sector: Involves the transformation of raw or intermediate materials into goods e.g. manufacturing steel into cars, or textiles into clothing. (A builder and a dressmaker would be workers in the secondary sector.)

  • Tertiary sector: Involves the provision of services to consumers and businesses, such as baby-sitting, cinema and banking. (A shopkeeper and an accountant would be workers in the tertiary sector.)


More details about the various phases of Economic Development follow. As this process was far from being homogenous geographically, the balance between these sectors differs widely among the various regions of the world.


HISTORY


Ancient times

The ancient economy was mainly based on Subsistence Farming . The exchange of goods happened within a Barter Economy . In Ancient Greece , when the word 'economy' arose, the majority of people were Bond Slaves of the Freeholders . Economic discussion was driven by Scarcity . Aristotle (384-322 B.C.) was the first to differentiate between a Use Value and an Exchange Value of goods. (Politics, Book I). The Exchange Ratio he defined was not only the expression of the value of goods but of the relations between the people involved in Trade . For most of the time in history economy therefore stood in opposition to institutions with ''fixed'' exchange ratios as Reign , State , Religion , Culture and Tradition .


Middle ages

In Medieval times the great conquerors raised Venture Capital (from ''ventura'', ital.; ''risk'') to finance their captures. The capital should be refunded by the goods they would bring up in the New World . Merchants such as Jakob Fugger (1459-1525) and Giovanni Di Bicci De' Medici (1360-1428) founded the first Bank s. The discoveries of Marco Polo (1254-1324), Christopher Columbus (1451-1506) Vasco De Gama (1469-1524) lead to a first World Economy , meaning international trade between the continents. The first Enterprises therefore were trading establishments. In 1513 the first Stock Exchange was founded in Antwerpen . Economy at the time meant firstly Trade .


Early modern times

The European captures became branches of the ) was a first approach to intermediate between private wealth and Public Interest .
The Secularization in Europe allowed states to use the immense property of the church for the development of towns. The influence of the Nobles decreased. The first Secretaries Of State for economy started their work. Bankers like Amschel Mayer Rothschild (1773-1855) started to finance national projects such as wars and Infrastructure . Economy from then on meant national economy as a topic for the economic activities of the Citizens of a State .


The industrial revolution

The first are offered at a Natural Price generated by the use of Competition - Supply and Demand - and the Division Of Labour . He maintained that the basic motive for Free Trade is human Self Interest . The so-called Self Interest Hypothesis became the Anthropological basis for economics. Thomas Malthus (1766-1834) transferred the idea of supply and demand to the problem of Over Population . The United States Of America became the place where millions of Expatriates from all European countries were searching for free Economic Evolvement .
In Europe ) and lead to Economic Growth . The period today is called Industrial Revolution because the system of Production and Division Of Labour enabled the Mass Production of Goods .


Capitalism and communism

Especially in England the ideas of Adam Smith became reality while the Economization —the process of always diminishing the Efforts Of Production —lead to Mass Poverty , Starvation , Urbanization and Pauperization of the population. Karl Marx (1818-1883) and the German industrialist and philosopher Friedrich Engels (1820-1895) described economy as the "system of capitalism".
The Exploitation of Labour and nature by the capitalist is creating a Surplus Value . The Capital will Accumulate itself and finally destroy the Competition . Therefore the system of Communism should liberate the economy from the reign of capital. The first Centrally Planned Economy was established after the Russian Revolution Of 1917 by Lenin .
Other states launched Social Security systems in order to minimize the effects of uncontrolled capitalism, called Manchester Capitalism .


After World War II

In order to build up the countries destroyed in two . In 1958 Kenneth Galbraith (1908-2006) was the first to speak of an Affluent Society . In most of the countries the economic system is called a Social Market Economy .


Postmodern society

The Globalization pushes national economies and rules in the backyard. The global and controversial discussion on the politics of the World Bank , the World Trade Organization and Global Players within the World Economic Forum as well as the discussion of global Ecology and Sustainability issues influences the definition of economy.
Joseph E. Stiglitz today defines economy to be a ''global public good''. Economists like Peter Barnes and Alexander Dill are reclaiming the Commons and give new definitions including new phenomena like Freeware . Game Theorists such as Ernst Fehr and Klaus M. Schmidt are disproving the Self-interest Hypothesis . A so-called Gift Economy is the topic for widespread activities of Grassroot movements as well as of the credit programs of Nobel laureate Muhammed Yunus . The Wealth of Nations Report 2006 of the World Bank for the first times tracks Social and Human Capital . The change of definitions is to be continued. There's also Neoclassical Economics .


ECONOMIC MEASURES

There are number of ways to measure economic activity of a nation. These methods of measuring economic activity include:



GDP

The GDP - Gross domestic product of a country measures the size of its Economy.
