Trade is the voluntary exchange of goods, services, or both. Trade is also called commerce. A mechanism that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and services. Modern traders instead generally negotiate through a medium of exchange, such as money. As a result, buying can be separated from selling, or earning. The invention of money (and later credit, paper money and non-physical money) greatly simplified and promoted trade. Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade.
Trade exists for many reasons. Due to specialisation and division of labor, most people concentrate on a small aspect of production, trading for other products. Trade exists between regions because different regions have a comparative advantage in the production of some tradable commodity, or because different regions' size allows for the benefits of mass production. As such, trade at market prices between locations benefits both locations.
Trading can also refer to the action performed by traders and other market agents in the financial markets.
EC was transformed into the European Union, which accomplished the Economic and Monnetary Union (EMU) in 2002, through introducing the Euro , and creating this way a real single market between 13 member states as of January 1, 2007.
The first instances of money were objects with intrinsic value. This is called commodity money and includes any commonly-available commodity that has intrinsic value; historical examples include pigs, rare seashells, whale's teeth, and (often) cattle. In medieval Iraq, bread was used as an early form of money. In Mexico under Montezuma cocoa beans were money. [1]
Currency was introduced as a standardised money to facilitate a wider exchange of goods and services. This first stage of currency, where metals were used to represent stored value, and symbols to represent commodities, formed the basis of trade in the Fertile Crescent for over 1500 years.
Numismatists have examples of coins from the earliest large-scale societies, although these were initially unmarked lumps of precious metal.[2]
Ancient Sparta minted coins from iron to discourage its citizens from engaging in foreign trade.
The system of commodity money in many instances evolved into a system of representative money. In this system, the material that constitutes the money itself had very little intrinsic value, but nonetheless such money achieves significant market value through scarcity or controlled supply.

Doha rounds
State control - trade centrally controlled by government planning.
Guild control - trade controlled by private business associations holding either de facto or government-granted power to exclude new entrants.
In contemporary times, the language has evolved to business and professional organisations, often controlled by academia. For example in many states, a person may not practice the professions of engineering, law, law enforcement, medicine, and teaching unless they have a college degree and, in some cases, a license.
Free enterprise - trade without significant central controls; market participants engage in trade based on their own individual assessments of risk and reward, and may enter or exit a given market relatively unimpeded.
